v0.14.0

This release is packed with new features. It ships the new w3vm package, which can be uses for blazing fast message simulation in the EVM. w3vm can be used in various ways, from Smart Contract testing and fuzzing to tracing of historic transactions or blocks. Better documentation and examples will be published in the upcoming month. For now you can refer to https://pkg.go.dev/github.com/lmittmann/w3/w3vm.

v0.10.0

w3 v0.10.0 adds support for transaction and call tracing. This release also contains some minor improvements and bug fixes.

Changes

• module/debug: Added RPC methods:
  • CallTraceCall
  • CallTraceTx
  • TraceCall
  • TraceTx
• module/eth: Dropped deprecated methods:
  • SendTransaction use SendTx instead
  • SendRawTransaction use SendRawTx instead
  • TransactionByHash use Tx instead
  • TransactionReceipt use TxReceipt instead
• Client.Call and Client.CallCtx now return the CallErrors error type, which allows to check which individual calls of a batch request failed (#18).

Bug Fixes

• Func.DecodeReturns now correctly decodes tuple types (#24, #25)
• Func.DecodeArgs now returns an error instead of panicking if len(input) < 4 (#22)

v0.9.1

Hotfix release for a regression in eth.CallFunc that was introduced in v0.9.0.

Changes

• fixed a regression in eth.CallFunc
• Bumped github.com/ethereum/go-ethereum from 1.10.23 to 1.10.25

v0.9.0

w3 v0.9.0 is packed with new RPC method bindings in the eth namespace and
introduces a new Message type that is used in e.g. eth.Call(...) that supports
passing a Func and its Args directly so arguments can be encoded automatically
by e.g. eth.Call(...).

This release contains breaking changes.

Changes

• module/eth: Added RPC Methods:

  • eth.AccessList(...)
  • eth.EstimateGas(...)
  • eth.BlockTxCountByHash(...)
  • eth.BlockTxCountByNumber(...)
  • eth.TxByBlockHashAndIndex(...)
  • eth.TxByBlockNumberAndIndex(...)
  • eth.UncleByBlockHashAndIndex(...)
  • eth.UncleByBlockNumberAndIndex(...)
  • eth.UncleCountByBlockHash(...)
  • eth.UncleCountByBlockNumber(...)

• module/eth: Refactored RPC Methods:

  • eth.TransactionByHash(...) (deprecated) to eth.Tx(...)
  • eth.TransactionReceipt(...) (deprecated) to eth.TxReceipt(...)
  • eth.SendRawTransaction(...) (deprecated) to eth.SendRawTx(...)
  • eth.SendTransaction(...) (deprecated) to eth.SendTx(...)
  • The deprecated methods will be removed in the next release.

• w3types:

  • Added new Message types that is used in eth.Call(...), eth.EstimateGas(...) and eth.AccessList(...).
  • Added new State types that can be used in eth.Call(...) to override existing state.

• Bumped github.com/ethereum/go-ethereum from 1.10.19 to 1.10.23

Breaking Changes

• Refactored package core to w3types
• module/eth:
  • Dropped types RPCBlock, RPCHeader, RPCTransaction, RPCReceipt, AccountOverrides, Account
  • eth.Call(...) uses w3types.Message instead of ethereum.CallMsg

v0.8.1
