17-29: Consider documenting the EIP-1559 removal strategyThe current code comments extensively document EIP-1559 support, but the implementation is being disabled. Consider updating this documentation to:
- Explain why EIP-1559 is being disabled
- Document the transition strategy
- Clarify how legacy transactions will be handled going forward
EIP-1559 code is already disabled, but priority fee handling should be removed
The code shows that EIP-1559 transaction creation (
DynamicFeeTx) is already commented out inzetaclient/chains/evm/signer/signer.go, and only legacy transactions are being created. However, the priority fee handling code in the reviewed file is now redundant since it's not being used in transaction creation. This code should be simplified to only handle legacy gas pricing.

zetaclient/chains/evm/signer/gas.gosince it's not used in the legacy transaction creation- Consider removing the
PriorityFeefield from theGasstruct if it's not needed elsewhere🔗 Analysis chain

92-106: Review priority fee handling for EIP-1559 removalThe code still handles priority fees and includes logic for adjusting them. If EIP-1559 is being disabled, this section might need to be simplified to handle only legacy gas pricing.
Let's verify the transaction creation flow:
Let me search for transaction creation and EIP-1559 related code to verify the concern.

60-61: Verify complete EIP-1559 removal strategy
While the isLegacy() method is marked as unused, its presence alongside the EIP-1559 related fields (PriorityFee) suggests that the EIP-1559 support removal might be incomplete. Consider whether this method and associated fields should be removed entirely to maintain code clarity.
Let's verify other EIP-1559 related code that might need attention:
✅ Verification successful
EIP-1559 removal is correctly implemented
The code shows that EIP-1559 support has been properly disabled:
- All transactions are now using
LegacyTxtype, withDynamicFeeTxcode commented out insigner.go - The
isLegacy()method is correctly marked as unused with a reference to issue Gas pricing: ensurepriorityFee<gasFee[EIP-1559] #3221 - Tests for
DynamicFeeTxare explicitly skipped with the same issue reference - The remaining EIP-1559 related fields (
PriorityFee) are still used but only for gas price calculations, not for transaction type determination

235-241: Verify gas price optimization for legacy transactions
With EIP-1559 disabled, ensure that the gas price calculation in legacy transactions is optimized for the current network conditions. Consider implementing a gas price suggestion mechanism based on network congestion.

62-98: Consider maintaining test coverage with legacy transaction assertionsWhile skipping the DynamicFeeTx test is appropriate given the removal of EIP-1559 support, consider adding equivalent test cases for legacy transactions to maintain coverage of the gas price handling logic.
Consider adding a test case like this:
t.Run("SignOutbound - should correctly handle gas price for legacy tx", func(t *testing.T) { const gasPrice = 3 * 1_000_000_000 // 3 gwei cctx := getCCTX(t) cctx.OutboundParams[0].GasPrice = big.NewInt(gasPrice).String() txData, skip, err := NewOutboundData(ctx, cctx, 123, makeLogger(t)) require.False(t, skip) require.NoError(t, err) tx, err := evmSigner.SignConnectorOnReceive(ctx, txData) require.NoError(t, err) assert.Equal(t, ethtypes.LegacyTxType, int(tx.Type())) assert.Equal(t, int64(gasPrice), tx.GasPrice().Int64()) })zetaclient/chains/evm/signer/signer.go (2)
222-222: Consider removing the unused parameterThe chainID parameter is marked as unused with an underscore but could be removed entirely since it's no longer needed after disabling EIP-1559 support.
-func newTx( - _ *big.Int, +func newTx( data []byte, to ethcommon.Address, amount *big.Int, gas Gas, nonce uint64, ) (*ethtypes.Transaction, error) {
235-242: Clean up commented codeInstead of keeping the commented-out code, consider removing it entirely and tracking the changes in version control. This improves code readability and maintenance.

Line range hint 1-98: Test structure and coverage are well-maintained
The overall test structure is robust with comprehensive coverage of signing operations, proper error handling, and consistent test patterns. The changes maintain this quality while appropriately handling the EIP-1559 deprecation.

233-254: Verify gas price implications of disabling EIP-1559
The change to use only legacy transactions by removing EIP-1559 support might affect gas price optimization. Legacy transactions use a simpler but less efficient gas pricing model.
Run the following script to analyze gas price patterns in the codebase:
Consider:
- Adding a comment explaining why EIP-1559 is disabled
- Documenting the gas price strategy for legacy transactions
- Monitoring transaction confirmation times after this change
✅ Verification successful
Let me gather more information about the gas price implementation and EIP-1559 support in the codebase.
EIP-1559 support temporarily disabled for stability and consistency
The change to use only legacy transactions is an intentional stability measure, as evidenced by issue #3221 referenced in the code. The EIP-1559 implementation exists but is currently commented out to ensure consistent gas pricing behavior across different EVM chains.
Key findings:
- The
isLegacy()function is marked with//nolint:unusedindicating a temporary state - Test cases for DynamicFeeTx are skipped with explicit reference to issue Gas pricing: ensure
priorityFee<gasFee[EIP-1559] #3221 - The codebase maintains the EIP-1559 code structure for future re-enablement
Recommendations:
- Add a comment explaining the temporary nature of legacy-only transactions:
// Currently using legacy transactions only for stability across EVM chains
// EIP-1559 support is temporarily disabled - see issue #3221- Consider adding configuration flags to enable EIP-1559 per chain when the stability issues are resolved
