4-4: LGTM: Import addition is necessary.The fmt package import is required for formatting the eth_hash attribute value.
113-113: LGTM: Enhanced event attribute verification.The addition of the eth_hash attribute in the test case improves verification of transaction hash handling in Ethereum events, ensuring consistency between pending_ethereum_tx and EventEthereumTx events.
x/evm/keeper/msg_server.go (2)
83-83: LGTM! Gas consumption is now more direct and accurate.The change simplifies gas tracking by directly consuming the actual gas used from the EVM response, removing the need for intermediate calculations.
564-564: LGTM! Consistent gas consumption pattern for ERC20 minting.The change maintains consistency with the simplified gas tracking approach, directly consuming the actual gas used from the EVM response.

87-87: LGTM! Gas consumption is now handled more directly.The simplified gas consumption logic aligns well with the PR objective of removing the
blockGasUsedvariable while maintaining proper gas tracking.
87-87: Verify gas consumption behavior with multiple messages.Since this PR aims to improve handling of multiple Ethereum messages within a single transaction, let's verify that the gas consumption is correctly tracked in such scenarios.
✅ Verification successful
Gas consumption behavior is properly implemented for multiple messages
The gas consumption implementation correctly tracks and accumulates gas usage across multiple Ethereum messages within a single transaction. This is verified by:
- Individual gas consumption tracking for each operation (deploy, mint, execute)
- Proper gas metering implementation in the msg_server
- Comprehensive test coverage in
gas_used_test.gothat verifies correct gas accounting across multiple messages🏁 Scripts executed
The following scripts were executed for the analysis:

#!/bin/bash # Description: Search for test cases that verify gas consumption with multiple messages # and check if the gas consumption is properly tracked. # Look for test files containing multiple message tests echo "Searching for relevant test files..." rg -l "multiple|message.*transaction|gas.*consumption" --type go # Look for specific gas consumption patterns in EVM calls echo "Checking gas consumption patterns..." ast-grep --pattern 'CallContractWithInput($$$)' # Look for gas meter usage patterns echo "Checking gas meter usage..." rg -A 2 "GasMeter\(\).ConsumeGas"Length of output: 1955

89-92: Robust replacement of pending transactions using transaction hashThe updated logic replaces pending transactions by matching the transaction hash (
EthHash), which is more reliable than relying solely on the message index (MsgIndex). This change enhances the robustness of the transaction parsing process and ensures accurate transaction mapping.eth/rpc/backend/nonce_test.go (1)
23-25:⚠️ Potential issueVerify function parameter alignment for
buildContractCallTxThe
buildContractCallTxfunction's signature has been updated to include an additional parameter. Ensure that the argument100_000corresponds to the correct parameter in the updated function signature. There might be a mismatch between the expectedgasLimitoramountparameter and the provided arguments.eth/rpc/backend/gas_used_test.go (1)
191-234: Comprehensive test for gas usage with multiple messagesThe
TestMultipleMsgsTxGasUsagefunction is a valuable addition that effectively verifies gas consumption for each message within a single transaction. The test correctly asserts that the gas used is within expected limits and that the account balance reflects the total gas consumed. The implementation follows best practices and enhances test coverage.eth/rpc/backend/backend_suite_test.go (1)
226-226: LGTM! Good improvement in test flexibility.The parameterization of gas limits allows for more comprehensive testing of different gas usage scenarios, which aligns well with the PR's goal of improving gas usage tracking.
