  • Integration test scripts to deposit and prove deposit for Bootstrap
  • Then we can run the generate.js
  • Follows the same logic as the price feeder tool to determine the last finalized epoch / slot, the validator status, the effective balance, etc. However, one question is how to get the validator pub key from the hashed form. It is not clear how the price feeder handles it either.

This PR fixes a potentially major (yet unnoticed) bug that the same constants (such as the ETH1_DEPOSIT_ADDRESS and GENESIS_TIME) were used across all networks.

Summary by CodeRabbit

  • New Features

    • Introduced new environment variables for integration testing, enhancing configuration capabilities.
    • Added a new NetworkConfig contract for managing network parameters.
    • Implemented a BeaconOracle contract for managing beacon chain data.
    • Enhanced Bootstrap contract with new public functions for validator management.
    • Updated the ExoCapsule contract to improve initialization and withdrawal logic.
    • Introduced a new VerifyDepositNST contract for integration testing of deposit functionalities.
    • Updated scripts for genesis file handling and improved logic for managing validator states.
    • Enhanced error handling mechanisms across various scripts and contracts.
  • Bug Fixes

    • Improved error handling in various scripts and contracts to ensure robustness.
  • Documentation

    • Updated comments and documentation for clarity across multiple contracts and scripts.
  • Tests

    • Expanded test coverage for the new NetworkConfig contract and updated existing tests to reflect changes in initialization parameters.

A lot of the parameters such as the beacon genesis time, the deneb time
and the deposit address are dependent on the network chosen for
deployment. This change allows a library to provide these constants,
based on the `block.chainid`.

Additionally, it creates the possibility of using a separately deployed
contract for integration networks (refer to the next commit), for which,
the parameters can be dynamically provided via `INetworkConfig`.

As a side effect, the default chain_id used in tests has been changed to
let `NetworkConstants` library provide these constants during tests.

foundry.toml (1)

16-17: Consider making chain_id configurable for different test environments

While setting chain_id = 1 makes the NetworkConstants work, hard-coding it to mainnet might limit testing flexibility. Consider making this configurable through environment variables, similar to how RPC endpoints are handled, to facilitate testing across different networks.

Example approach:

-chain_id = 1
+chain_id = "${CHAIN_ID}"
.env.example (3)

25-25: Add description for BEACON_CHAIN_ENDPOINT

The purpose and expected format of this endpoint should be documented with a comment, similar to other variables in the file.

-BEACON_CHAIN_ENDPOINT=
+# Beacon chain HTTP endpoint for querying validator data
+BEACON_CHAIN_ENDPOINT=

34-35: Add format specifications for timestamps

The timestamp fields INTEGRATION_BEACON_GENESIS_TIMESTAMP and INTEGRATION_DENEB_TIMESTAMP should include comments specifying the expected format (Unix timestamp, ISO 8601, etc.).

-INTEGRATION_BEACON_GENESIS_TIMESTAMP=
-INTEGRATION_DENEB_TIMESTAMP=
+# Unix timestamp for beacon chain genesis
+INTEGRATION_BEACON_GENESIS_TIMESTAMP=
+# Unix timestamp for Deneb hard fork
+INTEGRATION_DENEB_TIMESTAMP=

30-36: Consider grouping related environment variables

The integration testing variables could be better organized by grouping them under a clear section header and including a description of their collective purpose.

-# These are used for integration testing ETH PoS
+# =============================================================================
+# ETH PoS Integration Testing Configuration
+# These variables are used to configure the environment for Ethereum PoS
+# integration testing, including deposit contract, timing parameters, and
+# network upgrade specifications.
+# =============================================================================
script/integration/deposit.sh (1)

25-31: Improve environment variable naming and documentation

While the variables are set correctly, consider these improvements for clarity and maintainability:

  1. Add validation for timestamp values
  2. Document the expected format and units of each variable
  3. Consider prefixing variables with a more specific namespace

Consider applying these improvements:

+# Validate timestamp
+if ! [[ "$timestamp" =~ ^[0-9]+$ ]]; then
+    echo "Error: Invalid genesis timestamp"
+    exit 1
+fi
+
+# Environment variables for integration testing
+# All timestamps are in Unix epoch seconds
+# INTEGRATION_BEACON_GENESIS_TIMESTAMP: The genesis time of the beacon chain
+# INTEGRATION_DENEB_TIMESTAMP: The activation time of the Deneb fork
+# INTEGRATION_SECONDS_PER_SLOT: Number of seconds per slot
+# INTEGRATION_SLOTS_PER_EPOCH: Number of slots per epoch
+# INTEGRATION_DEPOSIT_ADDRESS: The deposit contract address
 export INTEGRATION_BEACON_GENESIS_TIMESTAMP=$timestamp
 export INTEGRATION_DENEB_TIMESTAMP=$timestamp
 export INTEGRATION_SECONDS_PER_SLOT=$seconds_per_slot
 export INTEGRATION_SLOTS_PER_EPOCH=$slots_per_epoch
 export INTEGRATION_DEPOSIT_ADDRESS=$deposit_address
-export SENDER=$sender
+export INTEGRATION_SENDER=$sender
src/interfaces/INetworkConfig.sol (3)

10-32: Consider adding validation requirements in documentation.

While the interface methods are well-defined, consider adding @dev documentation notes specifying that the implementing contract should:

  • Ensure returned values are non-zero where appropriate
  • Validate that getSecondsPerEpoch() returns value equal to getSecondsPerSlot() * getSlotsPerEpoch()

36-47: Optimize struct field ordering and complete documentation.

  1. Consider reordering fields to optimize for storage packing:
 struct NetworkParams {
+    uint64 slotsPerEpoch;
+    uint64 secondsPerSlot;
     address depositContractAddress;
     uint256 denebHardForkTimestamp;
-    uint64 slotsPerEpoch;
-    uint64 secondsPerSlot;
     uint256 beaconGenesisTimestamp;
 }
  1. Add documentation for the beaconGenesisTimestamp parameter:
 /// @param depositContractAddress The address of the deposit contract for the network.
 /// @param denebHardForkTimestamp The timestamp of the Deneb hard fork for the network.
 /// @param slotsPerEpoch The number of slots in an epoch for the network.
 /// @param secondsPerSlot The number of seconds in a slot for the network.
+/// @param beaconGenesisTimestamp The genesis timestamp of the beacon chain.

1-47: Well-designed interface that addresses PR objectives.

This interface effectively solves the issue mentioned in the PR objectives regarding the use of same constants across different networks. By providing a configurable interface for network parameters, it allows for network-specific values of critical constants like deposit contract address and genesis time.

Consider adding a network identifier or chain ID parameter to prevent configuration mismatches across different networks.

script/integration/prove.sh (2)

37-46: Consider enabling the slot waiting logic.

The commented-out slot waiting logic could be useful for ensuring proper synchronization with the beacon chain. However, it needs proper error handling and timeout mechanisms.

Consider implementing this with proper safeguards:

+# Wait till the slot is reached (with timeout)
+seconds_per_slot=$(jq -r .data.SECONDS_PER_SLOT "$SCRIPT_DIR/spec.json")
+timeout=300  # 5 minutes timeout
+elapsed=0
+
+while [ $elapsed -lt $timeout ]; do
+    response=$(curl -s http://localhost:3500/eth/v1/beacon/headers)
+    if [ $? -ne 0 ]; then
+        echo "Error: Failed to fetch current slot"
+        exit 1
+    fi
+    
+    current_slot=$(echo "$response" | jq -r '.data[0].header.message.slot')
+    if [ $? -ne 0 ] || [ -z "$current_slot" ]; then
+        echo "Error: Failed to parse current slot"
+        exit 1
+    }
+    
+    if (( current_slot > slot )); then
+        break
+    fi
+    
+    echo "Waiting for slot $slot, current slot is $current_slot"
+    sleep "$seconds_per_slot"
+    elapsed=$((elapsed + seconds_per_slot))
+done
+
+if [ $elapsed -ge $timeout ]; then
+    echo "Error: Timeout waiting for slot $slot"
+    exit 1
+fi

1-55: Consider adding configuration file support.

The script contains multiple hardcoded values (URLs, ports) that should be configurable for different environments.

Consider adding a configuration file (e.g., config.sh) to store environment-specific values:

# config.sh
BEACON_NODE_URL=${BEACON_NODE_URL:-"http://localhost:3500"}
PROOF_GENERATOR_URL=${PROOF_GENERATOR_URL:-"http://localhost:8989"}
PROOF_GENERATOR_TIMEOUT=${PROOF_GENERATOR_TIMEOUT:-300}

This would make the script more maintainable and reusable across different environments.

script/integration/2_VerifyDepositNST.s.sol (1)

19-28: Consider using address type for nstDepositor.

The nstDepositor is declared as uint256 but appears to be used as an address in startBroadcast. Consider changing it to address type for better type safety and clarity.

-    uint256 nstDepositor;
+    address nstDepositor;
test/foundry/unit/NetworkConfig.t.sol (3)

11-16: Consider using a shared test configuration file

The hardcoded constants could be moved to a shared test configuration file to:

  1. Enable reuse across different test files
  2. Make it easier to update values for different test environments
  3. Maintain consistency across test suites

30-61: Consider adding edge cases for timestamp-related tests

While the basic test coverage is good, consider adding edge cases for timestamp-related functions:

  1. Timestamps near uint256 max value
  2. Timestamps before genesis
  3. Boundary conditions for epoch calculations

Example test case:

function testTimestampOverflow() public {
    uint256 maxTimestamp = type(uint256).max;
    vm.warp(maxTimestamp);
    // Add assertions here
}

1-103: Consider implementing a test fixture pattern

To improve test maintainability and reduce duplication:

  1. Create a base test contract with common setup and utilities
  2. Extend it for specific test cases
  3. Use fixtures for different network configurations

This would make it easier to:

  • Add tests for different network configurations
  • Share common test utilities
  • Maintain consistency across test suites
src/libraries/NetworkConstants.sol (4)

3-3: Consider pinning the Solidity version

Using ^0.8.0 allows any version from 0.8.0 to 0.9.0 (excluding 0.9.0). To ensure consistent compilation across different environments, consider pinning to a specific version.

-pragma solidity ^0.8.0;
+pragma solidity 0.8.23;

22-76: Consider optimizing chainId access and improving maintainability

The function could be optimized by storing chainId in a local variable to reduce storage reads. Additionally, consider breaking down the network-specific logic into separate internal functions for better maintainability.

 function getNetworkParams() internal view returns (NetworkParams memory) {
-    uint256 chainId = block.chainid;
+    uint256 chainId = _getChainId();
     if (chainId == 1) {
-        // mainnet
-        return NetworkParams(
-            0x00000000219ab540356cBB839Cbe05303d7705Fa,
-            1_710_338_135,
-            SLOTS_PER_EPOCH_DEFAULT,
-            SECONDS_PER_SLOT_DEFAULT,
-            1_606_824_023
-        );
+        return _getMainnetParams();
     } else if (chainId == 11_155_111) {
-        // sepolia
-        return NetworkParams(
-            0x7f02C3E3c98b133055B8B348B2Ac625669Ed295D,
-            1_706_655_072,
-            SLOTS_PER_EPOCH_DEFAULT,
-            SECONDS_PER_SLOT_DEFAULT,
-            1_655_733_600
-        );
+        return _getSepoliaParams();
     } // ... similar for other networks
 }

+function _getChainId() private view returns (uint256) {
+    return block.chainid;
+}

+function _getMainnetParams() private pure returns (NetworkParams memory) {
+    return NetworkParams(
+        0x00000000219ab540356cBB839Cbe05303d7705Fa,
+        1_710_338_135,
+        SLOTS_PER_EPOCH_DEFAULT,
+        SECONDS_PER_SLOT_DEFAULT,
+        1_606_824_023
+    );
+}

106-109: Optimize getSecondsPerEpoch to reduce storage reads

The function makes two separate calls to getNetworkParams(), which could be optimized by storing the result in a local variable.

 function getSecondsPerEpoch() external view returns (uint64) {
-    return getNetworkParams().slotsPerEpoch * getNetworkParams().secondsPerSlot;
+    NetworkParams memory params = getNetworkParams();
+    return params.slotsPerEpoch * params.secondsPerSlot;
 }

12-117: Consider a more extensible approach for network configurations

The current implementation requires code changes to add new networks. Consider implementing a more extensible approach that would allow adding new networks without modifying the library code. This could be achieved through:

  1. A separate configuration contract that can be updated
  2. A registry pattern for network configurations
  3. An upgradeable proxy pattern for network parameters

This would make the system more maintainable and reduce the need for redeployments when adding new networks.

Would you like me to provide a detailed implementation for any of these approaches?

script/17_WithdrawalValidator.s.sol (2)

Line range hint 91-94: Consider parameterizing the proof file paths.

The script currently uses hardcoded JSON file paths for loading validator and withdrawal proofs. Consider making these paths configurable through environment variables or constructor parameters for better flexibility and testing.

-        string memory validatorInfo = vm.readFile("script/withdrawalProof_fullwithdraw_2495260_2472449.json");
+        string memory proofPath = vm.envOr("WITHDRAWAL_PROOF_PATH", 
+            string("script/withdrawalProof_fullwithdraw_2495260_2472449.json"));
+        string memory validatorInfo = vm.readFile(proofPath);

Also applies to: 123-126


Line range hint 73-77: Consider extracting magic numbers into named constants.

The proof validation uses magic numbers (3, 46) for array length checks. These should be extracted into named constants for better maintainability and documentation.

+    uint256 private constant EXPECTED_STATE_ROOT_PROOF_LENGTH = 3;
+    uint256 private constant EXPECTED_VALIDATOR_ROOT_PROOF_LENGTH = 46;
+
     function _loadValidatorProof() internal {
         // ...
-        require(validatorProof.stateRootProof.length == 3, "state root proof should have 3 nodes");
+        require(validatorProof.stateRootProof.length == EXPECTED_STATE_ROOT_PROOF_LENGTH, 
+            "Invalid state root proof length");
-        require(validatorProof.validatorContainerRootProof.length == 46, "validator root proof should have 46 nodes");
+        require(validatorProof.validatorContainerRootProof.length == EXPECTED_VALIDATOR_ROOT_PROOF_LENGTH, 
+            "Invalid validator root proof length");
script/7_DeployBootstrap.s.sol (2)

64-64: LGTM! Consider enhancing documentation.

Using a pre-deployed beacon oracle instead of deploying a new one is a good optimization that saves gas and aligns with the PR's goal of addressing network-specific configurations.

Consider adding a comment explaining why using the pre-requisite is preferred (e.g., gas savings, network consistency) and where to find the pre-requisite contract addresses for different networks.


Line range hint 38-42: Document the rationale for TVL limits.

The TVL limits are set to 5% (1/20) of total supply for both tokens. This seems arbitrary and could be a significant parameter that affects system security and economics.

Consider:

  1. Making the fraction configurable rather than hardcoded
  2. Documenting the rationale for choosing 5%
  3. Adding validation to ensure the calculated limits are within safe bounds
src/libraries/BeaconChainProofs.sol (1)

Line range hint 162-186: Consider adding SafeMath for timestamp comparison

While the logic for determining the execution payload header field tree height is correct, consider adding SafeMath for the timestamp comparison to prevent potential overflow issues.

-        uint256 executionPayloadHeaderFieldTreeHeight = withdrawalTimestamp < denebForkTimestamp
+        uint256 executionPayloadHeaderFieldTreeHeight = SafeMath.lt(withdrawalTimestamp, denebForkTimestamp)
             ? EXECUTION_PAYLOAD_HEADER_FIELD_TREE_HEIGHT_CAPELLA
             : EXECUTION_PAYLOAD_HEADER_FIELD_TREE_HEIGHT_DENEB;
test/foundry/unit/ClientChainGateway.t.sol (1)

Line range hint 247-249: Add test cases for networkConfig initialization

While the test suite is comprehensive, consider adding specific test cases to verify:

  1. The initialization of networkConfig
  2. Any functionality that depends on or validates networkConfig

Add a test case in the Initialize contract:

+ function test_NetworkConfigInitialized() public {
+     assertEq(clientGateway.NETWORK_CONFIG(), address(0));
+ }
test/foundry/BootstrapDepositNST.t.sol (1)

103-104: Document the purpose of networkConfig field

The networkConfig field is being added to ImmutableConfig but is initialized with address(0). Consider:

  1. Adding documentation to explain the purpose of this field
  2. Verifying if address(0) is an appropriate default value

Add a comment above the field to explain its purpose:

 BootstrapStorage.ImmutableConfig memory config = BootstrapStorage.ImmutableConfig({
     exocoreChainId: exocoreChainId,
     beaconOracleAddress: address(beaconOracle),
     vaultBeacon: address(vaultBeacon),
     exoCapsuleBeacon: address(capsuleBeacon),
     beaconProxyBytecode: address(beaconProxyBytecode),
+    // Address of the network configuration contract that stores network-specific constants
     networkConfig: address(0)
 });

Line range hint 281-289: Consider extracting capsule setup logic into a helper function

The capsule setup logic (creating a new capsule and setting its storage slots) is duplicated across test cases. Consider extracting this into a helper function to improve maintainability and reduce code duplication.

+    function _setupCapsule(address capsuleAddress) internal returns (ExoCapsule) {
+        ExoCapsule anotherCapsule = new ExoCapsule(address(0));
+
+        bytes32 gatewaySlot = bytes32(stdstore.target(capsuleAddress).sig("gateway()").find());

+
+        bytes32 ownerSlot = bytes32(stdstore.target(capsuleAddress).sig("capsuleOwner()").find());

+        vm.store(capsuleAddress, beaconOraclerSlot, bytes32(uint256(uint160(address(beaconOracle)))));
+
+        return anotherCapsule;

-        vm.store(address(anotherCapsule), gatewaySlot, bytes32(uint256(uint160(address(this)))));
-
-        bytes32 ownerSlot = bytes32(stdstore.target(address(anotherCapsule)).sig("capsuleOwner()").find());
-        vm.store(address(anotherCapsule), ownerSlot, bytes32(uint256(uint160(address(capsuleOwner)))));
-
-        bytes32 beaconOraclerSlot = bytes32(stdstore.target(address(anotherCapsule)).sig("beaconOracle()").find());
-        vm.store(address(anotherCapsule), beaconOraclerSlot, bytes32(uint256(uint160(address(beaconOracle)))));
+        ExoCapsule anotherCapsule = _setupCapsule(address(anotherCapsule));

Line range hint 367-379: Consider consolidating duplicate capsule initialization logic

The capsule initialization logic in WithdrawalSetup is similar to DepositSetup. Consider creating a base test contract that both setups can inherit from to avoid code duplication.

+contract CapsuleTestBase is Test {
+    function _initializeCapsule(address withdrawalCredentials) internal returns (ExoCapsule) {
+        ExoCapsule phantomCapsule = new ExoCapsule(address(0));
+        address capsuleAddress = _getCapsuleFromWithdrawalCredentials(withdrawalCredentials);
+        vm.etch(capsuleAddress, address(phantomCapsule).code);
+        return ExoCapsule(payable(capsuleAddress));
+    }
+}
+
-contract WithdrawalSetup is Test {
+contract WithdrawalSetup is CapsuleTestBase {
     // ... existing code ...
     
     function setUp() public {
         // ... existing code ...
-        ExoCapsule phantomCapsule = new ExoCapsule(address(0));
-        address capsuleAddress = _getCapsuleFromWithdrawalCredentials(_getWithdrawalCredentials(validatorContainer));
-        vm.etch(capsuleAddress, address(phantomCapsule).code);
-        capsule = ExoCapsule(payable(capsuleAddress));

         // ... rest of the code ...
     }

7-7: Nitpick: Consistent Numeric Literal Formatting

Consider using consistent formatting for numeric literals. The ALLOWED_CHAIN_ID is written with an underscore (31_337) for readability. Ensure that this style is applied consistently across the codebase or adjust it for uniformity.


40-40: Suggestion: Avoid Hardcoding Values in Error Messages

The error message in the require statement hardcodes the chain ID value:

require(block.chainid == ALLOWED_CHAIN_ID, "only the 31337 chain ID is supported for integration tests");

To prevent discrepancies if ALLOWED_CHAIN_ID changes, consider referencing the constant directly in the error message. While Solidity doesn't support string interpolation in error messages, you can use custom error types introduced in Solidity 0.8.4 for more informative errors:

error UnsupportedChainId(uint256 provided, uint256 expected);

require(block.chainid == ALLOWED_CHAIN_ID, UnsupportedChainId(block.chainid, ALLOWED_CHAIN_ID));

This approach ensures consistency and provides clearer feedback during integration tests.


71-72: Gas Optimization: Cache Calculated Value to Reduce Storage Reads

In the getSecondsPerEpoch() function, you're calculating the value by multiplying two storage variables:

return params.slotsPerEpoch * params.secondsPerSlot;

While this avoids storing a derived value, it results in two storage reads each time the function is called. If this function is called frequently, consider caching the calculated value in the constructor to minimize gas costs:

Apply this diff to cache the value:

     require(beaconGenesisTimestamp > 0, "Beacon genesis timestamp must be set for integration network");
     params = NetworkParams(deposit, denebTimestamp, slotsPerEpoch, secondsPerSlot, beaconGenesisTimestamp);
+
+    secondsPerEpoch = slotsPerEpoch * secondsPerSlot;
 }

 /// @inheritdoc INetworkConfig
 function getSecondsPerEpoch() external view returns (uint64) {
-    // reading from storage is more expensive than performing the calculation
-    return params.slotsPerEpoch * params.secondsPerSlot;
+    return secondsPerEpoch;
 }

You'll need to declare secondsPerEpoch as a state variable:

uint64 private secondsPerEpoch;

This reduces the number of storage reads from two to one when getSecondsPerEpoch() is called.


35-39: Style Improvement: Streamline Comment Sections

The explanatory comments in the constructor are detailed but could be more concise for readability:

// the value of 31337 is known to be a reserved chain id for testing.
// it is different from Anvil's 1337 to avoid confusion, since it does not support PoS.
// the downside of this number is that another chain id must be configured in `foundry.toml` to be used
// by default, during tests. setting this configuration also prevents NetworkConstants from complaining
// about Unsupported Network during tests, so it is worth it.

Consider summarizing the key points to enhance clarity:

// Using chain ID 31337 for integration tests to differentiate from Anvil's 1337, which doesn't support PoS.
// Requires configuring this chain ID in `foundry.toml` to prevent Unsupported Network errors during tests.
script/integration/BeaconOracle.sol (4)

37-37: Typo in error message documentation

There is a duplicate "the" in the error message documentation. It should read "Timestamp out of range for the beacon roots precompile."


82-82: Typo in documentation: "available" misspelled

The word "available" is misspelled as "avaliable" in the comment. Please correct it to "available."


60-64: Optimize staticcall usage in addTimestamp

In the addTimestamp function, the staticcall to BEACON_ROOTS with _targetTimestamp only checks for success without utilizing the returned data. Since the findBlockRoot function subsequently performs staticcalls to retrieve the block root, this initial staticcall may be redundant. Consider removing it or refactoring the logic to avoid unnecessary calls, thereby saving gas.


83-83: Inconsistent comment style

Line 83 uses a single-line comment // instead of the triple-slash /// used in the surrounding documentation comments. For consistency and proper documentation generation, consider changing it to ///.

src/storage/ExoCapsuleStorage.sol (3)

40-50: Consider making VERIFY_BALANCE_UPDATE_WINDOW_SECONDS configurable

While the extensive comments provide clarity, consider making VERIFY_BALANCE_UPDATE_WINDOW_SECONDS a configurable parameter. This would allow flexibility across different networks with varying slot times, ensuring the contract remains adaptable.


99-134: Refactor repetitive getter functions to reduce code duplication

The internal view functions getDenebHardForkTimestamp, getSlotsPerEpoch, getSecondsPerEpoch, and getBeaconGenesisTimestamp share a similar pattern. Consider refactoring to eliminate redundancy and enhance maintainability.

Apply this refactor to create a generic getter function:

+function _getNetworkParameterUint256(
+    function () internal pure returns (uint256) constantFunction,
+    function (address) external view returns (uint256) configFunction
+) internal view returns (uint256) {
+    if (NETWORK_CONFIG == address(0)) {
+        return constantFunction();
+    } else {
+        return configFunction(NETWORK_CONFIG);
+    }
+}

function getDenebHardForkTimestamp() internal view returns (uint256) {
-    if (NETWORK_CONFIG == address(0)) {
-        return NetworkConstants.getDenebHardForkTimestamp();
-    } else {
-        return INetworkConfig(NETWORK_CONFIG).getDenebHardForkTimestamp();
-    }
+    return _getNetworkParameterUint256(
+        NetworkConstants.getDenebHardForkTimestamp,
+        INetworkConfig.getDenebHardForkTimestamp
+    );
}

function getSlotsPerEpoch() internal view returns (uint64) {
-    if (NETWORK_CONFIG == address(0)) {
-        return NetworkConstants.getSlotsPerEpoch();
-    } else {
-        return INetworkConfig(NETWORK_CONFIG).getSlotsPerEpoch();
-    }
+    return uint64(_getNetworkParameterUint256(
+        NetworkConstants.getSlotsPerEpoch,
+        INetworkConfig.getSlotsPerEpoch
+    ));
}

function getSecondsPerEpoch() internal view returns (uint64) {
-    if (NETWORK_CONFIG == address(0)) {
-        return NetworkConstants.getSecondsPerEpoch();
-    } else {
-        return INetworkConfig(NETWORK_CONFIG).getSecondsPerEpoch();
-    }
+    return uint64(_getNetworkParameterUint256(
+        NetworkConstants.getSecondsPerEpoch,
+        INetworkConfig.getSecondsPerEpoch
+    ));
}

function getBeaconGenesisTimestamp() internal view returns (uint256) {
-    if (NETWORK_CONFIG == address(0)) {
-        return NetworkConstants.getBeaconGenesisTimestamp();
-    } else {
-        return INetworkConfig(NETWORK_CONFIG).getBeaconGenesisTimestamp();
-    }
+    return _getNetworkParameterUint256(
+        NetworkConstants.getBeaconGenesisTimestamp,
+        INetworkConfig.getBeaconGenesisTimestamp
+    );
}

This refactor reduces code duplication and makes it easier to maintain and extend in the future.


40-50: Typographical corrections in comments

There are minor typographical errors in the comments that could be corrected for clarity:

  • Line 49~: "this one. So, there is no need" should be "this one, so there is no need".

Apply this diff to correct the typo:

-/// is higher than this one. So, there is no need to make this parameter configurable based on the network.
+/// is higher than this one, so there is no need to make this parameter configurable based on the network.
src/core/ExoCapsule.sol (1)

410-410: Clarify error message in require statement

The require condition allows timestamp to be equal to beaconChainGenesisTime, but the error message states "timestamp should be greater than beacon chain genesis timestamp". Consider updating the error message to "timestamp should be greater than or equal to beacon chain genesis timestamp" for consistency.

137-139: Consider Separating Virtual Tokens for Clarity

Adding VIRTUAL_STAKED_ETH_ADDRESS at index 0 of whitelistTokens and starting loops from i = 1 could lead to confusion or potential off-by-one errors. To enhance readability and maintainability, consider handling virtual tokens separately or explicitly documenting the indexing strategy.

script/generate.js (2)

303-306: Address the TODO regarding public key retrieval

The code contains a TODO comment about retrieving the correct validator public keys instead of hashes. This is crucial for accurate validator identification and affects the ClientChainGateway and overall network functionality.

Would you like assistance in implementing the retrieval of the correct public keys from their hashes? I can help by providing code snippets or opening a GitHub issue.


827-827: Handle asynchronous write operation errors

When writing the updated genesis file, consider handling potential errors from the asynchronous writeFile operation. Although unlikely, adding a try-catch around this operation enhances reliability.

- await fs.writeFile(RESULT_GENESIS_FILE_PATH, jsonBig.stringify(genesisJSON, null, 2));
+ try {
+   await fs.writeFile(RESULT_GENESIS_FILE_PATH, jsonBig.stringify(genesisJSON, null, 2));
+   console.log('Genesis file updated successfully.');
+ } catch (writeError) {
+   console.error('Error writing genesis file:', writeError.message);
+ }

Line range hint 1068-1077: Clarify vm.deal amount in test24_Stake_InvalidValue

In test24_Stake_InvalidValue, the test stakes {value: 31 ether} to validate that staking with an incorrect amount reverts. However, vm.deal provides 33 ether to addrs[0], which might be confusing. Consider adjusting vm.deal to provide exactly 31 ether to make the test intent clearer.


Line range hint 1218-1236: Future implementation note in test28_ProcessBeaconChainWithdrawal

The test28_ProcessBeaconChainWithdrawal function expects a revert due to Errors.NotYetSupported.selector. Since this feature is not implemented yet, consider updating this test when the functionality becomes available to ensure comprehensive coverage.


Line range hint 1276-1295: Optimize storage access in _enableNativeRestaking and _disableNativeRestaking

In the helper functions _enableNativeRestaking and _disableNativeRestaking, consider caching the storage slot or abstracting the logic to reduce repetitive code. This can enhance readability and maintainability.

16-17: Verify test behavior across different networks

Given the PR's mention of issues with constants being reused across networks, we should verify that this change doesn't mask underlying problems with network-specific configurations.

✅ Verification successful

Based on the search results, I can make a determination about the network-specific configurations. The results show:

  1. No NetworkConstants contract was found in the codebase, suggesting it might have been removed or renamed.
  2. Network configuration is now handled through a NetworkConfig contract that explicitly checks for chain ID 31337 (for integration tests) and contains proper validation.
  3. The tests demonstrate proper handling of network-specific constants (like BEACON_CHAIN_GENESIS_TIME, SLOTS_PER_EPOCH, etc.) with explicit values.

Let me verify the NetworkConfig contract implementation to ensure it properly handles network-specific configurations:


Let me check the actual implementation of NetworkConfig to understand how it handles network-specific configurations:


Let me check the interface to fully understand the contract's requirements:


Setting chain_id = 1 in foundry.toml is correct and necessary

The codebase shows a well-designed separation between test and production environments:

  1. The NetworkConfig contract explicitly documents that it's "used for integration testing and is a substitute for the NetworkConstants library"
  2. It enforces chain_id 31337 for integration tests
  3. The code comments specifically mention: "another chain id must be configured in foundry.toml to be used by default, during tests"
  4. Setting chain_id = 1 in foundry.toml allows tests to run with mainnet constants while the actual test environment uses chain_id 31337

This setup ensures proper testing behavior while maintaining network-specific configurations.

27-27: Verify the implications of initializing ExoCapsule with address(0)

The initialization of ExoCapsule with address(0) needs careful consideration as this will affect all proxy instances during the upgrade.

Let's verify the ExoCapsule constructor implementation and its dependencies:

✅ Verification successful

Let me gather more information about the ExoCapsule contract implementation to understand how the address(0) parameter is used.


Based on the gathered information, I can now provide the final response:

Using address(0) for ExoCapsule initialization is safe in this upgrade context

The ExoCapsule contract inherits from ExoCapsuleStorage where the constructor parameter networkConfig_ is only used to set the NETWORK_CONFIG immutable variable. In the upgrade script context:

  • The address(0) parameter is safe as this is just an implementation contract that will be used as a logic contract behind a beacon proxy
  • All existing proxy instances will retain their original storage, including their network configuration
  • This pattern is consistently used across tests and deployment scripts

31-31: Verify the hardcoded deposit address

The hardcoded deposit address 0x696969... appears to be a placeholder. This could be dangerous if accidentally used in production.

✅ Verification successful

The previous output showed partial information about the deposit address usage in integration scripts. Let's gather more context about how this address is used and if there are any other deposit addresses defined in environment files or integration scripts.


The hardcoded deposit address is a safe default for integration testing

The address 0x696969... is only used as a default fallback value in integration testing scripts when the INTEGRATION_DEPOSIT_ADDRESS environment variable is not set. This is evident from:

  1. The address is only used in script/integration/1_DeployBootstrap.s.sol with vm.envOr() which provides a default value if the environment variable is not set
  2. In actual usage, script/integration/deposit.sh exports the real deposit address from genesis configuration: export INTEGRATION_DEPOSIT_ADDRESS=$deposit_address
  3. The placeholder address is not used in any production code, only in integration test scripts

32-33: Verify slot and epoch configurations

The values INTEGRATION_SECONDS_PER_SLOT=4 and INTEGRATION_SLOTS_PER_EPOCH=3 seem unusually low compared to mainnet values (12 seconds per slot, 32 slots per epoch). While this might be intentional for testing, it should be documented why these values differ.

✅ Verification successful

Based on the search results, I can now generate a final response. The code shows these values are used in integration tests with proper validation, and the README confirms these are specifically for localnet testing purposes.

Integration test configuration values are properly validated

The low values for INTEGRATION_SECONDS_PER_SLOT and INTEGRATION_SLOTS_PER_EPOCH are specifically used for local integration testing, as evidenced by:

  • Values are properly validated in DeployBootstrap.s.sol with bounds checking
  • They are used within the integration test scripts (script/integration/ directory)
  • The README explicitly mentions these are localnet test configurations

script/12_RedeployClientChainGateway.s.sol (1)

67-68: Verify implications of initializing networkConfig to address(0)

The initialization of networkConfig to address(0) requires careful consideration:

  1. This might be problematic if other contracts or the price feeder tool expect a valid network configuration address.
  2. Given that this PR aims to fix the issue of using same constants across networks, we should ensure that address(0) doesn't reintroduce similar problems.

Let's verify the usage of networkConfig in other contracts:

Consider:

  1. Adding inline documentation explaining why address(0) is acceptable here
  2. Adding validation in the ClientChainGateway constructor if a non-zero network config is required
  3. Implementing a mechanism to update the network config post-deployment if needed
script/13_DepositValidator.s.sol (3)

22-22: LGTM: Import aligns with network-specific constant requirements.

The addition of NetworkConstants import supports the PR's objective of fixing network-specific constant handling.


32-32: Verify initialization timing of GENESIS_BLOCK_TIMESTAMP.

The change from constant to immutable is appropriate for network-specific values. However, we should verify:

  1. The initialization timing in the constructor
  2. The value's consistency across different networks
#!/bin/bash
# Search for NetworkConstants implementation and usage
echo "Searching for NetworkConstants implementation..."
ast-grep --pattern 'contract NetworkConstants {
  $$$
  function getBeaconGenesisTimestamp() $$ {
    $$$
  }
  $$$
}'

echo "Checking for other usages of getBeaconGenesisTimestamp..."
rg "getBeaconGenesisTimestamp" -A 3

Line range hint 95-96: Consider adding timestamp validation checks.

The beaconBlockTimestamp calculation now uses a network-specific genesis time. Consider adding validation to ensure:

  1. The calculated timestamp is not in the future
  2. The slot number is within reasonable bounds
  3. The timestamp aligns with the network's epoch boundaries

This will help prevent potential issues with cross-network validator proofs.

12-12: Verify the deposit contract address

The hardcoded deposit contract address appears to be a placeholder. Ensure this matches the expected address for the integration network.

✅ Verification successful

The hardcoded address is correct for test environment

The address 0x1234567890AbcdEF1234567890aBcdef12345678 is intentionally used as a placeholder in the test file NetworkConfig.t.sol. This is appropriate because:

  1. The actual deposit contract addresses for different networks are properly defined in NetworkConstants.sol:

    • Mainnet: 0x00000000219ab540356cBB839Cbe05303d7705Fa
    • Sepolia: 0x7f02C3E3c98b133055B8B348B2Ac625669Ed295D
    • Holesky: 0x4242424242424242424242424242424242424242
  2. The test file uses a mock implementation (ETHPOSDepositMock) and is specifically designed for integration tests on chain ID 31337 (local testnet).

script/14_CorrectBootstrapErrors.s.sol (3)

Line range hint 1-24: Verify the reinitializer pattern implementation

The comment at the top indicates this script uses a reinitializer pattern, requiring changes to modifier versions in both Bootstrap and ClientChainGateway contracts.

Let's verify the reinitializer implementation:

#!/bin/bash
# Check reinitializer usage in both contracts
ast-grep --pattern 'reinitializer($VERSION)'

# Verify the initialize function modifiers
ast-grep --pattern 'function initialize($$$) $MODIFIER {
  $$$
}'

Line range hint 82-91: Verify the initialization timestamp logic

The initialization uses a hardcoded timeframe of "1 week from now" (168 hours). This could be problematic if:

  1. The deployment gets delayed
  2. Different networks need different initialization windows
  3. The script needs to be rerun

Let's check for similar timestamp handling:

#!/bin/bash
# Search for other timestamp-based initializations
rg "block\.timestamp \+" 

# Check if this timing is referenced in tests
rg "168 hours" test/

Consider making the initialization window configurable through environment variables or constructor parameters instead of hardcoding it.


99-100: Verify the implications of using address(0) for networkConfig

Setting networkConfig to address(0) might be problematic:

  1. The PR objectives mention issues with network-specific constants, but using a zero address doesn't solve this problem
  2. If the Bootstrap contract depends on this configuration for network-specific behavior, a zero address could lead to unexpected behavior

Let's verify how this configuration is used:

Consider implementing a proper NetworkConfig contract that encapsulates network-specific constants (ETH1_DEPOSIT_ADDRESS, GENESIS_TIME, etc.) instead of using address(0). This would:

  1. Provide better separation of concerns
  2. Make network-specific configurations explicit
  3. Prevent potential issues from uninitialized configurations
✅ Verification successful

Let's try with simpler commands to understand how networkConfig is used and verify if address(0) is a valid value.


Based on the search results, I can now provide a definitive response about using address(0) for networkConfig:

Setting networkConfig to address(0) is valid and intentionally supported

The codebase explicitly handles the zero address case for networkConfig:

  1. In BootstrapStorage.sol:
// networkConfig is allowed to be 0
if (config.networkConfig == address(0)) {
    depositContract = NetworkConstants.getDepositContractAddress();
} else {
    depositContract = INetworkConfig(config.networkConfig).getDepositContractAddress();
}
  1. In ExoCapsuleStorage.sol, similar fallback patterns exist for all network configuration values:
if (NETWORK_CONFIG == address(0)) {
    return NetworkConstants.getDenebHardForkTimestamp();
} else {
    return INetworkConfig(NETWORK_CONFIG).getDenebHardForkTimestamp();
}

The system is designed to fall back to hardcoded constants in NetworkConstants library when networkConfig is not provided, making address(0) a valid configuration option.

script/17_WithdrawalValidator.s.sol (2)

26-27: LGTM! Import aligns with PR objectives.

The addition of NetworkConstants library import helps address the issue of constants being reused across different networks, as mentioned in the PR objectives.


38-38: Verify the genesis timestamp initialization across networks.

The change from a hardcoded constant to an immutable value from NetworkConstants is a good improvement. However, we should verify that:

  1. The genesis timestamp is correctly initialized for different networks
  2. The timestamp calculation in _loadValidatorProof() remains accurate with this change
✅ Verification successful

Based on the shell script results, I can now generate a final response as we have sufficient information about the genesis timestamp implementation and usage:

Genesis timestamp initialization is properly handled across networks

The verification shows that:

  • The genesis timestamp is correctly initialized through NetworkConstants.getBeaconGenesisTimestamp() with proper fallback to network-specific configuration
  • The timestamp calculation in _loadValidatorProof() remains accurate, using the formula GENESIS_BLOCK_TIMESTAMP + SECONDS_PER_SLOT * slot
  • The implementation includes proper validation checks and network-specific configurations through NetworkConfig
  • The constant SECONDS_PER_SLOT = 12 is consistently used across the codebase

The changes maintain consistency with the beacon chain specifications while providing flexibility for different network configurations.

The change from new ExoCapsule() to new ExoCapsule(address(0)) needs verification:

  2. Verify if this change is consistent with the contract's intended behavior
✅ Verification successful

Let me generate additional scripts to verify the safety of passing address(0) to ExoCapsule constructor.


Based on the search results, I can now generate the final response since we have found that ExoCapsule's initialize function explicitly validates the gateway address to prevent address(0):

Passing address(0) to ExoCapsule constructor is safe as it's only used for implementation contract

The ExoCapsule contract properly validates the gateway address in its initialize function with the check require(gateway_ != address(0), "ExoCapsule: gateway address can not be empty"). The constructor parameter is only used for the implementation contract which is never initialized, while actual ExoCapsule instances are created as proxies and properly initialized with non-zero addresses.

66-66: Verify the implications of using address(0) in ExoCapsule constructor

The ExoCapsule constructor now requires an address parameter, but it's initialized with address(0). This could indicate:

  1. A placeholder value that needs to be updated later
  2. An intentional null state initialization

Please clarify the intended behavior and verify if address(0) is safe to use here.

}'

82-83: Review the immutable networkConfig initialization

The addition of networkConfig to ImmutableConfig struct is good for network-specific settings, but two points need attention:

  1. Since this is an immutable configuration, verify if address(0) is the intended final value or if it needs to be set to a proper address during deployment
  2. Consider adding validation in the contract to ensure critical addresses are not address(0) if they're required for operation
✅ Verification successful

Based on the shell script results, I can now generate the final response:

The address(0) initialization for networkConfig is intentionally designed

The codebase explicitly handles the zero address case for networkConfig:

  • In BootstrapStorage.sol, there's a comment "networkConfig is allowed to be 0"
  • When networkConfig is address(0), the contract falls back to NetworkConstants for configuration values
  • When set to a valid address, it uses INetworkConfig interface to fetch values

This design pattern is consistently used across the codebase, making it a valid implementation choice rather than an oversight.

Zero address initialization for ExoCapsule is correct in test context

The zero address initialization for ExoCapsule in test files is intentional and correct. The ExoCapsule contract is designed to work with both zero and non-zero network config addresses:

  • In test environments, address(0) is commonly used as seen across multiple test files
  • In integration/production scenarios, it accepts a network config address (as seen in script/integration/1_DeployBootstrap.s.sol)
  • The contract handles both cases appropriately by falling back to constants when network config is zero (verified in src/storage/ExoCapsuleStorage.sol)

Let me check the INetworkConfig interface and ClientChainGateway implementation to complete the verification.


Setting networkConfig to address(0) is the correct implementation

The initialization of networkConfig with address(0) is valid and intentional because:

  1. The codebase implements a fallback mechanism where address(0) triggers the use of hardcoded NetworkConstants instead of a configurable INetworkConfig contract.
  2. ClientChainGateway doesn't directly use networkConfig - it's primarily used by BootstrapStorage for deposit contract resolution.
  3. The pattern is consistently used across all test cases and deployment scripts.
  4. There's explicit validation in BootstrapStorage that allows networkConfig to be zero: // networkConfig is allowed to be 0

Based on the comprehensive search results, I can now provide the final response:

Using address(0) for networkConfig is a valid initialization pattern

The codebase explicitly supports initializing ExoCapsule with address(0) for networkConfig. When networkConfig is set to address(0), the system falls back to using NetworkConstants library instead of a NetworkConfig contract instance. This is evidenced by:

  • The BootstrapStorage contract explicitly allows networkConfig to be 0 with the comment "networkConfig is allowed to be 0"
  • The codebase has a fallback mechanism in multiple places when networkConfig is address(0)
  • Most test files and deployment scripts intentionally use address(0) for networkConfig

No changes needed in deployment scripts for the optional networkConfig field

The networkConfig field has been properly handled in all deployment scripts and tests:

  • All deployment scripts already include the field in their ImmutableConfig struct initialization
  • The field is correctly set to address(0) in most deployments, which is valid as per the constructor's documentation

The ExoCapsule constructor is being called with address(0) as a parameter. This seems to be used for creating a phantom capsule for testing purposes, but the purpose and implications of this parameter should be clearly documented.

✅ Verification successful

Let me gather more context about the ExoCapsuleStorage to understand the implications of passing address(0).


Using address(0) in ExoCapsule constructor is valid for test purposes

The usage of address(0) in the test is valid and intentional. The ExoCapsuleStorage has a fallback mechanism when NETWORK_CONFIG is set to address(0), as seen in the getDenebHardForkTimestamp() function. This allows the contract to function in test environments without requiring a real network configuration contract.

29-29: LGTM: ValidatorContainer library integration

The ValidatorContainer library is properly imported and integrated using the using directive for bytes32[] arrays, which is consistent with its usage in the code.

Also applies to: 52-52


796-796: LGTM: Proper tracking of validator pubkeys

The stakerToPubkeys mapping is updated after successful verification of the deposit proof, maintaining an accurate record of validator keys for each staker.


827-834: LGTM: Well-documented pubkey count accessor

The getPubkeysCount function is properly implemented with clear documentation, providing a view into the number of validators associated with each staker address.


693-701: LGTM: Special handling for virtual native staked ETH token

Good practice to handle the virtual token (VIRTUAL_NST_ADDRESS) differently from regular ERC20 tokens. The hardcoded values are appropriate for representing native staked ETH.

✅ Verification successful

Based on the results, I can generate the final response as the verification is complete. The ripgrep results show consistent handling of VIRTUAL_NST_ADDRESS across the codebase:

Verified: VIRTUAL_NST_ADDRESS is consistently handled as a special case

The virtual native staked ETH token (VIRTUAL_NST_ADDRESS) is properly handled across the codebase with special cases for:

  • Token info with hardcoded ETH values (name, symbol, decimals)
  • TVL limit restrictions (not allowed)
  • Deposit tracking and withdrawal logic
  • Special withdrawal handling through ExoCapsule
  • Proper error handling with specific error messages

script/integration/NetworkConfig.sol (1)

1-80: General Assessment: Code Quality and Compliance

The NetworkConfig contract is well-structured and effectively serves its purpose for integration testing. The use of constructor parameters and validation ensures that the contract is correctly initialized.

src/storage/ExoCapsuleStorage.sol (5)

4-7: Imports are appropriate and necessary

The addition of NetworkConstants and INetworkConfig imports correctly brings in the required interfaces and libraries for network configuration.


14-15: Clarification in documentation is helpful

The added comments explaining why the contract does not inherit from INetworkConfig enhance the code's readability and maintainability.


59-61: Immutable NETWORK_CONFIG variable correctly introduced

The introduction of the NETWORK_CONFIG immutable variable is appropriate. It allows the contract to reference the NetworkConfig contract dynamically or fallback to NetworkConstants when not set.


93-97: Constructor properly initializes NETWORK_CONFIG

The constructor correctly sets the NETWORK_CONFIG variable, ensuring that the contract has access to the correct network configuration upon deployment.


119-124: Possible typo in getSecondsPerEpoch function

The getSecondsPerEpoch function seems to retrieve seconds per epoch, but it calls getSecondsPerEpoch() which might return seconds per slot based on standard naming conventions. Please verify that getSecondsPerEpoch() returns the correct value.

Run the following script to check the return values of getSecondsPerEpoch:

src/core/ExoCapsule.sol (4)

135-136: Constructor updated with networkConfig_ parameter

The addition of the networkConfig_ parameter to the constructor and passing it to ExoCapsuleStorage enhances configurability. This change appears correct and aligns with the updates for dynamic network configurations.


209-209: Use of getSlotsPerEpoch() in withdrawalEpoch calculation

Replacing hardcoded values with getSlotsPerEpoch() improves flexibility across different network configurations. This ensures that withdrawalEpoch is accurately calculated based on the network's slot duration.


383-383: Utilization of getDenebHardForkTimestamp() for withdrawal validation

Incorporating getDenebHardForkTimestamp() into the validation process ensures that withdrawal container validation adapts to network upgrades. This enhances correctness and future-proofs the contract against protocol changes.


408-411: Refactored _timestampToEpoch to use dynamic genesis timestamp and epoch duration

The function now retrieves beaconChainGenesisTime using getBeaconGenesisTimestamp() and uses getSecondsPerEpoch() for epoch calculations. This improves adaptability to different network parameters and removes hardcoded values.

script/integration/1_DeployBootstrap.s.sol (3)

119-133: Initialization and Validation of Network Parameters

The network configuration parameters are correctly read from environment variables, and the validations ensure they are within acceptable ranges and types. The casting from uint256 to uint64 is safely guarded by require statements.


233-245: Loop Indexing Aligns with Token Arrays

The loops correctly start from i = 1 to skip the virtual token at whitelistTokens[0], ensuring that only actual tokens are processed. The use of vaults[i - 1] aligns with the adjusted indexing and prevents unintended interactions with the virtual token.


80-84: Verify Replacement of Hardcoded Constants with Configurable Parameters

To ensure consistency across different networks, verify that all instances of hardcoded constants like ETH1_DEPOSIT_ADDRESS and GENESIS_TIME have been replaced with the newly introduced environment variables or parameters.

Run the following script to search for any remaining hardcoded instances:

✅ Verification successful

Based on the search results, I can now generate the final response:

Hardcoded Constants Have Been Properly Replaced with Configurable Parameters

The codebase shows that the deposit address and genesis-related parameters are properly configured through environment variables and network-specific configurations:

  • Deposit addresses are managed through NetworkConstants.sol for different networks (mainnet, sepolia, holesky)
  • Genesis and network parameters are properly configured in NetworkConfig.sol
  • The integration deployment script (1_DeployBootstrap.s.sol) correctly uses environment variables:
    • depositAddress = vm.envOr("INTEGRATION_DEPOSIT_ADDRESS", ...)
    • Network parameters like denebTimestamp are read from environment
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash

test/foundry/ExocoreDeployer.t.sol (4)

49-50: Import NetworkConstants for centralized configuration

The addition of NetworkConstants import helps centralize network constants, ensuring consistency across the codebase.


334-334: Utilize NetworkConstants for beacon genesis timestamp

Initializing beaconOracle with EigenLayerBeaconOracle(NetworkConstants.getBeaconGenesisTimestamp()) centralizes the beacon genesis timestamp retrieval, enhancing consistency and maintainability.


339-339: Initialize ExoCapsule with address(0)

Passing address(0) to the ExoCapsule constructor is acceptable if the contract is designed to handle a null address. Ensure that any operations within ExoCapsule safely handle address(0) without causing unintended side effects.


364-365: Add networkConfig to ImmutableConfig with address(0)

Including networkConfig in BootstrapStorage.ImmutableConfig and initializing it to address(0) is acceptable if the downstream code can handle a null networkConfig address appropriately. Confirm that any logic dependent on networkConfig accounts for this possibility.

script/generate.js (5)

64-64: Ensure accurate prefix comparison in isValidBech32 function

The isValidBech32 function compares the decoded prefix with EXOCORE_BECH32_PREFIX. Confirm that EXOCORE_BECH32_PREFIX correctly represents the expected prefix for Exocore addresses.


368-374: Verify balance_list values with the team

There's a TODO comment indicating the need to check values with Qing. Ensure that the balance_list fields such as round_id, block, index, change, and balance are correctly set according to the application's requirements.

Please confirm these values to ensure accurate staker balance initialization.


804-817: Ensure the correct structure for oracle staker assets

The newly added staker_list_assets and staker_infos_assets should conform to the expected schema of the oracle module.

Confirm that these structures are correctly formed:

  • staker_list_assets should be an array of objects, each containing asset_id and staker_list with staker_addrs.
  • staker_infos_assets should include asset_id and staker_infos, where staker_infos is an array of staker information.

If needed, I can assist in reviewing the schema definitions.


73-73: Ensure all environment variables are defined

The BEACON_CHAIN_ENDPOINT variable is added to the destructured process.env. Confirm that this environment variable is properly defined in your environment or .env file to prevent undefined errors.

If it's not already in your .env.example, consider adding it for clarity.


55-56: Verify compatibility of imported modules

Modules imported from @lodestar/api and @lodestar/config/default are used. Ensure that these dependencies are installed and compatible with your project's Node.js version.

Run npm install @lodestar/api @lodestar/config if not already installed.

test/foundry/unit/Bootstrap.t.sol (10)

105-105: Initialization of capsuleImplementation with address(0)

The change to initialize capsuleImplementation with new ExoCapsule(address(0)) ensures compatibility with the updated constructor of ExoCapsule that requires an address parameter. This is appropriate and aligns with similar updates in other test files.


125-126: Verify the initialization of networkConfig with address(0)

In the initialization of BootstrapStorage.ImmutableConfig, the networkConfig field is set to address(0). Please ensure that this is intentional and that the zero address is acceptable in this context. If networkConfig is required by the contract logic, providing a valid address might be necessary to avoid potential issues.


1135-1136: Consistent usage of networkConfig in initialization tests

In the test15_Initialize_* functions, the networkConfig field is consistently set to address(0) within BootstrapStorage.ImmutableConfig. Since these tests check for initialization failures or edge cases, using the zero address is appropriate to validate that the contract correctly handles invalid configurations.

Also applies to: 1172-1173, 1210-1211, 1247-1248, 1285-1286, 1323-1324, 1360-1361, 1397-1398


Line range hint 1050-1066: Mocking ETHPOS deposit in test24_Stake

The test24_Stake function correctly sets up the environment by enabling native restaking and mocking the ETHPOS deposit. The use of vm.mockCall to simulate the deposit function of the ETHPOS contract ensures that the staking process can be tested without relying on external contracts.


Line range hint 1079-1088: Correctly handling disabled restaking in test24_Stake_WhenDisabled

The test24_Stake_WhenDisabled function appropriately tests the staking behavior when native restaking is disabled, confirming that the contract reverts as expected.


Line range hint 1090-1103: Proper capsule creation in test25_CreateExoCapsule

The test25_CreateExoCapsule function effectively tests the creation of an ExoCapsule and verifies that it is correctly registered to the owner. The assertions confirm that the capsule address is not zero and is properly associated with the owner.


Line range hint 1105-1114: Handling existing capsule in test25_CreateExoCapsule_AlreadyExists

In test25_CreateExoCapsule_AlreadyExists, the test ensures that attempting to create an ExoCapsule when one already exists correctly reverts. This validates the contract's ability to prevent duplicate capsule creation.


Line range hint 1155-1170: Validate state changes in test26_VerifyAndDepositNativeStake

The test26_VerifyAndDepositNativeStake function mocks the capsule to return a specific deposit value and checks the changes in deposit amounts. Ensure that the mocked return value accurately represents the expected behavior, and that the state changes reflect the intended logic.


Line range hint 1172-1181: Correct revert handling in test26_VerifyAndDepositNativeStake_WithEther

The test correctly expects a revert when verifyAndDepositNativeStake is called with a non-zero value, adhering to the contract's requirement that no Ether should be sent with this transaction.


Line range hint 1378-1386: Consistent error handling in test functions

Across the test functions test16_SetSpawnTime, test17_SetOffsetDuration, etc., error handling is correctly implemented using vm.expectRevert. Ensure that error messages and selectors used in these reverts are consistent with the contract's definitions.

64-71: Consider moving hardcoded delegation values to configuration.

The delegation address and amount are hardcoded in the test script. Consider moving these to environment variables or configuration file for better maintainability and flexibility across different test environments.

+    string memory delegationAddress = vm.envOr(
+        "INTEGRATION_DELEGATION_ADDRESS",
+        "exo1rtg0cgw94ep744epyvanc0wdd5kedwql73vlmr"

-        18 ether
+        delegationAmount
     );
test/foundry/unit/NetworkConfig.t.sol (4)

13-13: Consider using a more flexible approach for test addresses

Instead of hardcoding the deposit contract address, consider:

  1. Using makeAddr("deposit") to generate deterministic addresses for testing
  2. Adding a comment explaining why this specific address was chosen if it represents a real contract
-    address public constant DEPOSIT_CONTRACT_ADDRESS = 0x1234567890AbcdEF1234567890aBcdef12345678;
+    // Generate deterministic address for testing
+    address public constant DEPOSIT_CONTRACT_ADDRESS = makeAddr("deposit");

20-28: Consider adding post-deployment validations in setUp

The setup function could benefit from additional assertions to ensure the contract is properly initialized:

     function setUp() public {
         vm.chainId(31_337);
 
         networkConfig = new NetworkConfig(
             DEPOSIT_CONTRACT_ADDRESS, DENEB_TIMESTAMP, SLOTS_PER_EPOCH, SECONDS_PER_SLOT, BEACON_GENESIS_TIMESTAMP
         );
+        // Validate initial state
+        assertEq(address(networkConfig).code.length > 0, true, "Contract deployment failed");
+        assertEq(block.chainid, ALLOWED_CHAIN_ID, "Chain ID mismatch");
     }

52-55: Enhance epoch-related test coverage

The testGetSecondsPerEpoch function could be expanded to include additional test cases:

     function testGetSecondsPerEpoch() public {
         assertEq(networkConfig.getSecondsPerEpoch(), SECONDS_PER_SLOT * SLOTS_PER_EPOCH, "Seconds per epoch mismatch");
+        
+        // Test epoch boundary calculations
+        uint256 timestamp = BEACON_GENESIS_TIMESTAMP;
+        uint256 secondsPerEpoch = networkConfig.getSecondsPerEpoch();
+        
+        // Verify epoch start
+        assertEq((timestamp - BEACON_GENESIS_TIMESTAMP) % secondsPerEpoch, 0, "Not at epoch boundary");
+        
+        // Verify mid-epoch
+        timestamp += secondsPerEpoch / 2;
+        assertTrue((timestamp - BEACON_GENESIS_TIMESTAMP) % secondsPerEpoch != 0, "Should not be at epoch boundary");
     }

86-90: Strengthen invalid input testing

Consider expanding the negative test cases to include more edge cases:

     function testRevertInvalidSlotsPerEpoch() public {
+        // Test zero value
         vm.expectRevert("Slots per epoch must be set for integration network");
         new NetworkConfig(DEPOSIT_CONTRACT_ADDRESS, DENEB_TIMESTAMP, 0, SECONDS_PER_SLOT, BEACON_GENESIS_TIMESTAMP);
+        
+        // Test extremely large value
+        vm.expectRevert("Slots per epoch value is unreasonable");
+        new NetworkConfig(DEPOSIT_CONTRACT_ADDRESS, DENEB_TIMESTAMP, type(uint64).max, SECONDS_PER_SLOT, BEACON_GENESIS_TIMESTAMP);
+        
+        // Test non-power-of-two value
+        vm.expectRevert("Slots per epoch must be a power of two");
+        new NetworkConfig(DEPOSIT_CONTRACT_ADDRESS, DENEB_TIMESTAMP, 31, SECONDS_PER_SLOT, BEACON_GENESIS_TIMESTAMP);
     }

Similar improvements could be applied to other negative test cases.

script/integration/1_DeployBootstrap.s.sol (7)

Line range hint 86-91: Consider removing hardcoded private keys from the code.

While these are default Anvil test keys, it's best practice to avoid hardcoding any private keys, even test ones, directly in the source code. Consider moving these to a separate test configuration file.


146-148: Document the purpose of index 0 reservation.

The comment indicates that index 0 is reserved for VIRTUAL_STAKED_ETH_ADDRESS, but this design choice should be documented more clearly as it affects multiple functions in the contract.


211-213: Consider making the initialization buffer configurable.

The 24-hour buffer for initialization is hardcoded. Consider making this configurable through environment variables to support different testing scenarios.


218-220: Document the purpose of dummy implementation upgrade values.

The implementation upgrade address is set to 0x1 with dummy data "123456". These values should be documented to explain their purpose in the testing context.


245-246: Consider using exact approval amounts.

Using type(uint256).max for token approvals, while common, might be unnecessary for testing. Consider approving only the required amount for better testing accuracy.


Line range hint 393-396: Improve random number generation implementation.

The current random number generation using block.timestamp and block.prevrandao is not secure for production use. While this might be acceptable for testing, consider adding a comment explicitly stating this limitation.

 function random(uint256 _range) internal view returns (uint256) {
-    // Basic random number generation; consider a more robust approach for production
+    // WARNING: This is a simplified random number generation for testing purposes only.
+    // DO NOT use this in production as it's vulnerable to manipulation by miners/validators.

133-133: Handle errors when parsing exchange rates

When processing INTEGRATION_EXCHANGE_RATES, invalid inputs can cause exceptions. Ensure the code handles parsing errors gracefully.

Consider adding error handling:

-const exchangeRates = INTEGRATION_EXCHANGE_RATES.split(',').map(Decimal);
+const exchangeRates = INTEGRATION_EXCHANGE_RATES.split(',').map(rateString => {
+  try {
+    return new Decimal(rateString);
+  } catch (error) {

+  }
+});

316-316: Validate response from getStateValidators

When calling api.beacon.getStateValidators, ensure that the response contains the expected data and handle cases where validators may not be found.

Add a check before processing validatorStates:

const validatorStates = (await api.beacon.getStateValidators({stateId: stateRoot, validatorIds: pubKeys})).value();

+if (!validatorStates || validatorStates.length === 0) {
+  console.error(`No validator states found for pubKeys: ${pubKeys}`);
+  continue;
+}

The setup function includes appropriate error handling and initialization. The fallback value for INTEGRATION_NST_DEPOSITOR is acceptable as it uses Anvil default keys for testing purposes.


68-68: Verify the native token address convention.

The hardcoded native token address 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is commonly used to represent the native token, but let's verify this convention in the codebase.

✅ Verification successful

The native token address convention 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is consistently used across the codebase

The address is consistently defined as a constant VIRTUAL_STAKED_ETH_ADDRESS or VIRTUAL_NST_ADDRESS throughout the codebase, including in core contracts, tests, and scripts. This convention is well-documented in ExocoreGateway.sol where it's specifically noted as being used for Ethereum.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the native token address convention usage across the codebase

# Search for the native token address usage

1-104: Well-structured and comprehensive test suite!

The test file demonstrates good testing practices with:

  • Clear documentation
  • Comprehensive coverage of both positive and negative cases
  • Proper use of Forge testing utilities
  • Well-organized test structure

While there are opportunities for enhancement, the current implementation provides a solid foundation for testing the NetworkConfig contract.

  • Balance validation against maximum and ejection thresholds
  • Slashing and reward calculations

The getPubkeysCount function is properly implemented with clear documentation explaining its purpose and requirements.


796-796: Verify validatorIndex casting safety

The casting of proof.validatorIndex to bytes32 assumes the validator index fits within 32 bytes. Please verify that this assumption holds true across all possible validator indices to prevent data truncation.

✅ Verification successful

Let me analyze the validator index usage in the codebase to verify if there are any constraints or potential issues with casting to bytes32.


Let me check one more thing to understand how the validator index is used in the Beacon Chain proofs.


Based on the analysis of the codebase, I can now provide a final response about the validator index casting safety.

Validator index casting to bytes32 is safe

The casting of proof.validatorIndex to bytes32 is safe because:

  1. The validator index is defined as uint256 in the BeaconChainProofs library, which means it already fits within 32 bytes (256 bits)
  2. The only constraint found is that validator index must be non-zero, as checked in multiple test files
  3. The validator index is used in Merkle proof verification where it's combined with VALIDATOR_TREE_ROOT_INDEX using bitwise operations, indicating it's designed to work within the 256-bit space

Line range hint 117-847: Consider modularizing the genesis file generation logic.

The updateGenesisFile function is quite large and handles multiple concerns. Consider breaking it down into smaller, focused modules:

  • Token and oracle configuration
  • Validator and operator management
  • Native token deposit handling
  • Genesis file structure management

This would improve maintainability and testability.

264-270: Verify token ID calculation logic.

The token ID calculation (i + 1 - offset) might need verification to ensure it doesn't generate duplicate IDs when tokens are mapped to the same oracle feed.

✅ Verification successful

Token ID calculation is correctly handling duplicates

The token ID calculation (i + 1 - offset) is working as intended. The code shows a proper duplicate handling mechanism where:

  • The offset is incremented when a token name already exists in oracleTokens
  • For duplicates, the asset IDs are concatenated with commas in the existing entry
  • The offset subtraction in token ID ensures unique and sequential IDs even when tokens map to the same oracle feed

the whole looks good.

- The `nstETH` token needs to be added both as a token and as a feeder
- The `nstETH` token's `asset_id` needs to map back to the native
  (non-staked) token's `asset_id`
In the event that the Bootstrap contract has whitelisted `nstETH` but
not `ETH`, the `nstETH` entry will only fetch the effective balance and
the token price from the `ETH` entry will be missing. This commit fixes
that by manually adding an `ETH` entry to the oracle state in such an
event.

14-24: Add documentation for token mapping logic.

Consider adding comments to explain:

  • The relationship between tokenMetaInfos and tokenNamesForOracle arrays
  • Why nstETH asset_id is mapped to ETH in the oracle

84-93: Enhance environment variable validation error messages.

Consider providing more specific error messages that indicate which variable is missing:

-    throw new Error('One or more required environment variables are missing.');
+    const missingVars = [
+        ['INTEGRATION_BEACON_CHAIN_ENDPOINT', INTEGRATION_BEACON_CHAIN_ENDPOINT],
+        ['CLIENT_CHAIN_RPC', CLIENT_CHAIN_RPC],

+    ].filter(([name, value]) => !value).map(([name]) => name);
+    throw new Error(`Missing required environment variables: ${missingVars.join(', ')}`);

386-389: Define constants for validator status values.

Consider extracting the validator status string into a named constant for better maintainability:

+const VALIDATOR_STATUS = {
+    ACTIVE_ONGOING: 'active_ongoing'

402-428: Document slashing and rewards logic.

The slashing and rewards logic is complex and would benefit from detailed documentation explaining:

  • The conditions that trigger slashing
  • How the slashing amount is calculated
  • How rewards are distributed

Add comments like:

// Case 1: Slashing - When deposit is greater than effective balance
// This happens due to downtime penalties or other slashing conditions
// The slashing amount is first taken from withdrawable balance
// If withdrawable balance is insufficient, the remaining is taken from deposit

// Case 2: Rewards - When effective balance is greater than deposit
// This represents accumulated rewards
// The rewards are added to both deposit and withdrawable amounts

5-11: Consider adding validation for chain information constants

The clientChainInfo object contains critical chain configuration. Consider adding runtime validation to ensure all required fields are present and have valid values.

✅ Verification successful

Chain configuration values appear to be safe and consistent

The clientChainInfo configuration in script/generate.mjs appears to be correctly defined with appropriate values for Sepolia testnet. The values are:

  • Consistent with Sepolia's Layer Zero chain ID (40161)
  • Using standard Ethereum address length (20 bytes)
  • Setting reasonable finalization blocks (10) for testnet environment

No validation issues were found in the codebase that would contradict these values, and the configuration appears to be used appropriately in the genesis file generation process.

Tested the cases around native restaking, single ETH validator. Start by depositing 32 ETH and staking 18 ETH.

  • Run generate.mjs and get 32 ETH deposited, of which 14 ETH withdrawable immediately

30-30: Avoid hardcoding chain IDs.

The layer_zero_chain_id: 0 is hardcoded with a comment indicating it's a "virtual chain". Consider making this configurable through environment variables.

-  "layer_zero_chain_id": 0, // virtual chain
+  "layer_zero_chain_id": process.env.NATIVE_CHAIN_LAYER_ZERO_ID || 0, // virtual chain

458-466: Consider extracting magic numbers into named constants.

The balance validation uses magic numbers (8, 16) for slashing thresholds. These should be extracted into named constants for better maintainability.

+const MIN_SLASHED_BALANCE = ejectionBalance.div(2); // 8 ETH
+const MAX_SLASHED_BALANCE = ejectionBalance;        // 16 ETH

-if (effectiveBalance.gt(ejectionBalance)) {
+if (effectiveBalance.gt(MAX_SLASHED_BALANCE)) {
   throw new Error(
     `The effective balance of ${effectiveBalance} is greater than the ejection balance.`
   );
-} else if (effectiveBalance.lt(ejectionBalance.div(2))) {
+} else if (effectiveBalance.lt(MIN_SLASHED_BALANCE)) {
   throw new Error(
     `The effective balance of ${effectiveBalance} is less than half the ejection balance.`
   );
 }

515-570: Consider breaking down complex slashing logic into smaller functions.

The slashing calculation logic is complex and handles multiple scenarios. Breaking it into smaller, well-named functions would improve readability and maintainability.

Example refactoring:

+function calculateSlashProportions(totalDelegated, slashFromWithdrawable, withdrawableValue) {
+  let pendingSlashAmount = slashFromWithdrawable.minus(withdrawableValue);
+  if (pendingSlashAmount.gt(ZERO_DECIMAL)) {
+    return {
+      slashFromWithdrawable: withdrawableValue,
+      pendingSlashAmount
+    };
+  }
+  return {
+    slashFromWithdrawable,
+    pendingSlashAmount: ZERO_DECIMAL
+  };
+}

// Use in main code
-let slashFromWithdrawable = depositValue.minus(totalEffectiveBalance);
-let pendingSlashAmount = slashFromWithdrawable.minus(withdrawableValue);
-if (pendingSlashAmount.gt(ZERO_DECIMAL)) {
-  slashFromWithdrawable = withdrawableValue;
-} else {
-  pendingSlashAmount = new Decimal(0);
-}
+const { slashFromWithdrawable, pendingSlashAmount } = calculateSlashProportions(
+  totalDelegated,
+  depositValue.minus(totalEffectiveBalance),
+  withdrawableValue
+);

944-948: Be explicit about power value truncation and precision.

The power calculation truncates decimal places and converts to integer, which could lead to precision loss. Consider documenting the precision requirements and handling edge cases.

 validators.forEach((val) => {
-  val.power = val.power.toFixed(0);
+  // Truncate to integer as required by the consensus engine
+  // Note: This may lose precision for small power differences
+  val.power = val.power.toFixed(0);
   totalPower += parseInt(val.power, 10);
 });

102-118: LGTM! Well-structured utility functions.

The utility functions are concise, focused, and serve clear purposes.


139-142: Verify slot calculation edge case handling.

The code changes the header if the finalized slot is not at an epoch boundary. This could potentially miss important state information.

✅ Verification successful

Let me analyze the code further to understand the slot calculation handling better.


The slot calculation edge case is handled correctly

The code's behavior of fetching the block header at the epoch boundary when the finalized slot is not at an epoch boundary is actually the correct approach. This ensures consistent state retrieval at epoch boundaries, which is important for beacon chain synchronization. The implementation:

  1. First gets the latest finalized header
  2. If that header is not at an epoch boundary, it fetches the header at the start of that epoch
  3. This guarantees we always work with epoch-aligned state roots
🏁 Scripts executed

The following scripts were executed for the analysis:

12-25: Consider adding validation for token array ordering.

The comment indicates that tokenMetaInfos and tokenNamesForOracle must maintain the same order as whitelistTokens. This ordering dependency could be a source of bugs.

Consider creating a single source of truth by using an object that maps tokens to their metadata and oracle names, eliminating the ordering dependency.

✅ Verification successful

Let me analyze the token arrays usage in the codebase to verify if there are potential issues with the ordering dependency.


The array ordering dependency is properly validated and safe to use.

The code already implements proper validation to ensure array length consistency and correct token mapping:

  1. Length validation checks ensure all arrays have matching sizes:
if (supportedTokensCount != tokenMetaInfos.length) {
  throw new Error(...)
}
if (supportedTokensCount != tokenNamesForOracle.length) {
  throw new Error(...)
}
  1. Token type validation ensures correct mapping:
if (tokenNamesForOracle[i].toLowerCase().startsWith('nst')) {
  if (token.tokenAddress != VIRTUAL_STAKED_ETH_ADDR) {
    throw new Error('Oracle name refers to NST token but this is LST');
  }
}

While the arrays must maintain order alignment, the code has sufficient safeguards to prevent misalignment issues. The original review comment's concern is addressed by the existing validation logic.

🏁 Scripts executed

The following scripts were executed for the analysis:

249-254: Add comments to clarify loop indexing

In the loops where indexing starts from 1 (e.g., for (uint256 i = 1; i < whitelistTokens.length; i++)), it's to skip the VIRTUAL_STAKED_ETH_ADDRESS at index 0. Adding comments to explain this can improve code readability and prevent confusion.

110-113: Avoid hardcoding private keys in code

Including private keys directly in the code, even for testing purposes, poses security risks and can lead to accidental exposure. Consider moving these sensitive values into environment variables or secure configurations.


292-295: Avoid including sensitive information in comments

Mentioning mnemonics or other sensitive keys in comments can pose security risks. Even if placeholders, it's best to remove or sanitize these comments to prevent accidental exposure.


397-401: Verify the usage of the serialize method with StdJson

Ensure that the serialize method is correctly used with the StdJson library to serialize deployment addresses. Improper usage may lead to incorrect JSON formation or runtime errors.


Line range hint 406-409: Random number generation is acceptable for testing purposes

The random() function uses block.timestamp and block.prevrandao, which is acceptable in a testing environment. For production code, consider using a more secure source of randomness.

Line range hint 74-147: Enhance validation for network configuration parameters.

The network configuration validation is thorough but could be improved for better error handling and security.

Consider these enhancements:

-        require(denebTimestamp > 0, "Deneb timestamp must be set");
+        require(denebTimestamp > block.timestamp, "Deneb timestamp must be in the future");
-        require(beaconGenesisTimestamp > 0, "Beacon timestamp must be set");
+        require(beaconGenesisTimestamp <= block.timestamp, "Beacon genesis must be in the past");

402-409: Consider enhancing deployment tracking.

The deployment tracking could be improved to include more metadata and validation.

Consider adding:

 string memory key = "deployments";
 key.serialize("beaconOracleAddress", address(beaconOracle));
+key.serialize("deploymentTimestamp", block.timestamp);
+key.serialize("networkId", block.chainid);
 string memory start = key.serialize("bootstrapAddress", address(bootstrap));
+require(address(bootstrap) != address(0), "Bootstrap deployment failed");
 vm.writeFile("script/integration/deployments.json", start);

Line range hint 417-420: Improve random number generation for production.

The current random number generation is not suitable for production use.

Consider using a more secure random number generation method:

-        return (uint256(keccak256(abi.encodePacked(block.timestamp, block.prevrandao))) % (_range - 1)) + 1;
+        // For testing purposes only
+        require(_range > 1, "Invalid range");
+        bytes32 randomBytes = keccak256(abi.encodePacked(

+        ));
+        return (uint256(randomBytes) % (_range - 1)) + 1;
script/generate.mjs (6)

12-25: Consider using a more robust token mapping system.

The current implementation relies on array order matching between tokenMetaInfos and tokenNamesForOracle. This coupling could lead to subtle bugs if arrays get out of sync during maintenance.

Consider using an object mapping or enum to maintain the relationship:

-const tokenMetaInfos = [
-  'Staked ETH',
-  'Exocore testnet ETH',
-  'Lido wrapped staked ETH',
-];
-const tokenNamesForOracle = [
-  'nstETH', 'ETH', 'wstETH'
-]
+const TOKEN_CONFIG = {
+  STAKED_ETH: {
+    metaInfo: 'Staked ETH',
+    oracleName: 'nstETH'
+  },
+  EXOCORE_ETH: {
+    metaInfo: 'Exocore testnet ETH',
+    oracleName: 'ETH'
+  },
+  LIDO_ETH: {
+    metaInfo: 'Lido wrapped staked ETH',
+    oracleName: 'wstETH'
+  }
+};

30-31: Extract magic numbers into named constants.

The code uses magic numbers for layer_zero_chain_id and address_length.

Consider defining these as named constants:

+const VIRTUAL_CHAIN_ID = 0;
+const ETH_ADDRESS_LENGTH = 20;

const nativeChain = {
  "name": "Exocore",
  "meta_info": "The (native) Exocore chain",
  "finalization_blocks": 10,
-  "layer_zero_chain_id": 0, // virtual chain
-  "address_length": 20,
+  "layer_zero_chain_id": VIRTUAL_CHAIN_ID,
+  "address_length": ETH_ADDRESS_LENGTH,
}

108-113: Consider using a more descriptive prefix for AVS address generation.

The prefix 'chain-id-prefix' is generic and its purpose isn't immediately clear.

Consider using a more descriptive prefix:

function generateAVSAddr(chainID) {
-  const ChainIDPrefix = 'chain-id-prefix';
+  const AVS_ADDR_PREFIX = 'exocore-avs-addr';
-  const hash = keccak256(ChainIDPrefix + chainID);
+  const hash = keccak256(AVS_ADDR_PREFIX + chainID);
  return '0x' + hash.slice(-40);
}

784-785: Address TODO comment regarding oracle module setup.

The comment indicates a temporary solution that needs to be updated once the oracle module is set up.

Would you like me to help create a GitHub issue to track this improvement task?


1080-1080: Address TODO comment regarding staking data migration.

The comment indicates missing implementation for copying staking data from previous genesis.

Would you like me to help create a GitHub issue to track this missing implementation?


989-1034: Potential performance bottleneck in nested loops.

The code contains deeply nested loops with multiple contract calls, which could be slow for a large number of operators or tokens.

Consider:

  1. Batching contract calls using Promise.all
  2. Using Map/Set for faster lookups
  3. Caching repeated contract method calls

151-154: Review the TVL limit for virtual staked ETH.

Setting TVL limit to 0 for virtual staked ETH might need additional consideration.

✅ Verification successful

Based on the search results, I can now provide a final response:

Setting TVL limit to 0 for virtual staked ETH is the intended behavior.

The codebase consistently sets TVL limit to 0 for virtual staked ETH across multiple files, and this is by design because:

  1. In test/foundry/ExocoreDeployer.t.sol: Comment explicitly states "no limit for native staked ETH"
  2. In script/3_Setup.s.sol: Comment states "irrelevant for native restaking"
  3. TVL limits are not enforced for virtual staked ETH as it represents natively staked ETH on Ethereum, which has different validation mechanisms through the beacon chain proof verification.
🏁 Scripts executed

280-289: Verify ETH value in stake function.

The hardcoded 32 ETH value should be validated against network requirements.

✅ Verification successful

Based on the search results, I can see that this is a native staking contract for Ethereum validators, and the 32 ETH value is a fundamental requirement of the Ethereum network for validator deposits. The documentation and code show that this is specifically for depositing to the beacon chain, where 32 ETH is the standard validator deposit amount. This is not a configurable value as it's a core Ethereum protocol requirement.

The 32 ETH stake value is correct as it matches Ethereum network requirements.

The value is hardcoded because it's a protocol-level requirement for Ethereum validator deposits, not a configurable parameter that needs validation against network requirements.

408-412: Consider using a more robust JSON serialization approach.

The current JSON serialization approach using string concatenation could be fragile. Consider using a structured JSON library or creating a proper JSON object.

-        string memory key = "deployments";
-        key.serialize("beaconOracleAddress", address(beaconOracle));
-        string memory start = key.serialize("bootstrapAddress", address(bootstrap));
-        vm.writeFile("script/integration/deployments.json", start);
+        string memory json = string(abi.encodePacked(
+            '{"deployments":{"beaconOracleAddress":"', 
+            toHexString(address(beaconOracle)),
+            '","bootstrapAddress":"',
+            toHexString(address(bootstrap)),
+            '"}}'
+        ));
+        vm.writeFile("script/integration/deployments.json", json);

303-306: Remove or update outdated comments.

The comments about mnemonics and consensus public keys appear to be outdated or incomplete. Consider updating them to reflect the current implementation or remove if no longer relevant.


Line range hint 419-422: Improve random number generation for production use.

The current random number generation implementation using block.timestamp and block.prevrandao might not be secure enough for production use.

Consider using a more robust random number generation approach, such as Chainlink VRF, for production environments. However, since this is a test script, the current implementation is acceptable.

114-148: Well-structured parameter validation in setUp.

The validation of environment variables and parameters is thorough and well-organized. The explicit checks for length requirements and value ranges enhance the reliability of the deployment process.


217-218: Hardcoded time values need review.

The initialization uses hardcoded time values (24 hours and 1 seconds) which might not be suitable for all deployment scenarios.

Consider making these configurable through environment variables to support different deployment environments and testing scenarios.


152-155: Consider adding validation for tvlLimits array.

While the code initializes the tvlLimits array, there's no validation to ensure its elements are within acceptable bounds.

Consider adding validation:

 whitelistTokens.push(VIRTUAL_STAKED_ETH_ADDRESS);
-tvlLimits.push(0); // not enforced for virtual staked eth
+require(tvlLimits.length < type(uint256).max, "TVL limits array too large");
+tvlLimits.push(0); // not enforced for virtual staked eth

I also tested the truncation case wherein, instead of 32 ETH, the staker has delegated only 30 ETH and the effective balance goes below that number, say, 29.

In such a case, the withdrawable balance becomes 0 first and we are still left with 1 ETH to slash from the delegated 30 ETH. The script was able to do that successfully and handled the decimals well without generating any extra tokens.
