10-11: Enhance function documentation for better clarity.While the current documentation explains the rationale, consider adding:
- Return value documentation
- Example usage
- More details about block number handling in Cosmos
Consider updating the documentation:
-// MakeSigner returns a Signer based on the given chain config and block number. -// We use this instead of ethtypes.MakeSigner because cosmos always uses blockNumber for hard forks +// MakeSigner returns an ethtypes.Signer based on the given chain configuration and block number. +// Unlike ethereum's MakeSigner, this implementation always uses the exact block number for hard fork +// detection to align with Cosmos chain upgrade mechanics. +// +// Example usage: +// +// signer := types.MakeSigner(chainConfig, big.NewInt(blockNum)) +// signed, err := signer.SignatureValues(tx, sig)app/ante/sigs_test.go (1)
21-21: Consider using a named constant for the balance value.While the uint256 conversion is correct, consider extracting the magic number
10000000000into a named constant for better maintainability and clarity.+const defaultTestBalance = 10000000000 -acc.Balance = uint256.NewInt(10000000000) +acc.Balance = uint256.NewInt(defaultTestBalance)x/evm/keeper/hooks.go (1)
37-37: Add nil check for msg parameter.While the pointer parameter change aligns with go-ethereum v1.13.x, it introduces potential nil pointer risks.
Add a nil check at the start of the method:
func (mh MultiEvmHooks) PostTxProcessing(ctx sdk.Context, msg *core.Message, receipt *ethtypes.Receipt) error { + if msg == nil { + return errorsmod.Wrap(types.ErrInvalidParams, "nil message") + } for i := range mh {x/evm/types/tracer.go (1)
67-67: Consider updating documentation for interface changesThe change in method signature represents a breaking change in the EVMLogger interface implementation. Consider adding a comment explaining the rationale behind removing the duration parameter.
+// CaptureEnd implements vm.Tracer interface +// Note: time.Duration parameter was removed as part of go-ethereum v1.13.x upgrade func (dt NoOpTracer) CaptureEnd(_ []byte, _ uint64, _ error) {}x/evm/keeper/config.go (1)
64-66: Consider documenting the NoBaseFee logic.The NoBaseFee determination is a critical part of the London hardfork compatibility. Consider adding a comment explaining this logic for better maintainability.
+ // Set NoBaseFee flag based on London hardfork activation and fee market parameters noBaseFee := true if types.IsLondon(cfg.ChainConfig, ctx.BlockHeight()) { noBaseFee = k.feeMarketKeeper.GetParams(ctx).NoBaseFee }tests/importer/chain_ctx_test.go (2)
95-96: Improve VerifyHeader test coverage.The current test only verifies that no error is returned. Consider adding test cases that:
- Verify header validation with different consensus parameters
- Test invalid headers
- Validate compatibility with the upgraded go-ethereum types
Line range hint
1-120: Consider implementing a comprehensive test suite for ChainContext.Given the significant changes in the go-ethereum upgrade (v1.13.x) and the modifications to stateful precompiled contracts, the current test coverage is insufficient. Consider implementing:
- A table-driven test suite for each method
- Integration tests with the new go-ethereum types
- Benchmarks for performance-critical methods
- Fuzz testing for header verification
- Mock implementations for proper isolation
This would help improve the current patch coverage of 47.56% and ensure compatibility with the upgraded dependencies.

51-78: Consider adding explicit chain ID validationThe signer creation and transaction validation flow is correct, but consider adding an explicit chain ID validation before the sender recovery to provide clearer error messages.
signer := types.MakeSigner(ethCfg, blockNum) for _, msg := range tx.GetMsgs() { msgEthTx, ok := msg.(*evmtypes.MsgEthereumTx) if !ok { return ctx, errorsmod.Wrapf(errortypes.ErrUnknownRequest, "invalid message type %T, expected %T", msg, (*evmtypes.MsgEthereumTx)(nil)) } allowUnprotectedTxs := evmParams.GetAllowUnprotectedTxs() ethTx := msgEthTx.AsTransaction() + // Validate chain ID for protected transactions + if ethTx.Protected() && ethTx.ChainId().Cmp(chainID) != 0 { + return ctx, errorsmod.Wrapf( + errortypes.ErrInvalidChainID, + "invalid chain ID: got %s, expected %s", + ethTx.ChainId().String(), + chainID.String(), + ) + } + if !allowUnprotectedTxs && !ethTx.Protected() {x/evm/keeper/utils.go (1)
Based on the analysis of the codebase, I can now provide a final response regarding the test coverage concern.
Test coverage for gas calculations needs improvement
The codebase shows gaps in test coverage for intrinsic gas calculations, specifically:
- No dedicated test cases for
IntrinsicGasfunction variations- Missing test coverage for Shanghai EIP-3860 gas calculations
- Limited testing of protocol version combinations (homestead/istanbul)
Required test additions:
- Test cases in
x/evm/keeper/utils_test.gocovering:
- Contract creation with EIP-3860 initcode size gas costs
- Different combinations of homestead/istanbul flags
- Edge cases with varying data sizes and access lists
- Protocol version transitions affecting gas calculations

97-106: Enhance test coverage for gas calculation changes.Given the critical nature of gas calculations and the PR's coverage report showing gaps, please add test cases for:
- Shanghai EIP-3860 gas calculations
- Edge cases with different combinations of homestead/istanbul flags
- Contract creation vs regular transactions
Let me gather more information about the test coverage for gas calculations.
Let me try a different approach to analyze the test coverage.
Let me check the implementation of IntrinsicGas and related test files to get a complete picture.
Let me check for specific test coverage of the intrinsic gas calculation.

x/feemarket/types/params.go (1)
92-95: Consider enhancing documentation for default parameters.While the code changes are correct, it would be beneficial to document the specific values and rationale for using go-ethereum's defaults. This helps future maintainers understand the parameter selection.
Add comments explaining the values and their implications:
return Params{ NoBaseFee: DefaultNoBaseFee, + // Use go-ethereum's default value (8) for base fee adjustment BaseFeeChangeDenominator: params.DefaultBaseFeeChangeDenominator, + // Use go-ethereum's default value (2) for target gas utilization ElasticityMultiplier: params.DefaultElasticityMultiplier, BaseFee: sdkmath.NewIntFromUint64(params.InitialBaseFee),x/evm/statedb/journal.go (1)
144-147: Add documentation for transient storage implementationConsider adding documentation to explain:
- The purpose and lifecycle of transient storage
- The difference between transient and permanent storage
- When and how transient storage should be used
x/evm/types/tx_args.go (1)
176-176: Enhance error message clarity.Consider providing more context in the error message to help users understand the incompatibility.

173-280: Consider refactoring benchmarks to reduce duplication.The benchmark functions share similar patterns and could be refactored into a table-driven approach to improve maintainability and test coverage.
Consider refactoring the benchmarks like this:
func BenchmarkApplyTransactions(b *testing.B) { testCases := []struct { name string txData ethtypes.TxData enableFeemarket bool enableLondonHF bool }{ { name: "AccessListTx", txData: templateAccessListTx, enableLondonHF: true, }, { name: "LegacyTx", txData: templateLegacyTx, enableLondonHF: true, }, { name: "DynamicFeeTx", txData: templateDynamicFeeTx, enableFeemarket: true, enableLondonHF: true, }, } for _, tc := range testCases { b.Run(tc.name, func(b *testing.B) { suite := KeeperTestSuite{ enableFeemarket: tc.enableFeemarket, enableLondonHF: tc.enableLondonHF, } suite.SetupTestWithT(b) ethSigner := ethtypes.LatestSignerForChainID(suite.app.EvmKeeper.ChainID()) b.ResetTimer() b.ReportAllocs() for i := 0; i < b.N; i++ { b.StopTimer() tx, err := newSignedEthTx( tc.txData, suite.app.EvmKeeper.GetNonce(suite.ctx, suite.address), sdk.AccAddress(suite.address.Bytes()), suite.signer, ethSigner, ) require.NoError(b, err) b.StartTimer() resp, err := suite.app.EvmKeeper.ApplyTransaction(suite.ctx, tx) b.StopTimer() require.NoError(b, err) require.False(b, resp.Failed()) } }) } }rpc/backend/chain_info.go (2)

164-255: Consider enhancing error handling and documentation.The
FeeHistoryimplementation could benefit from:
- Documentation explaining the relationship between
userBlockCountandmaxBlockCount- More descriptive error messages for validation failures
- Clearer comments explaining the reward calculation logic
Apply these documentation improvements:
// FeeHistory returns data relevant for fee estimation based on the specified range of blocks. +// Parameters: +// - userBlockCount: number of blocks to fetch (max: FeeHistoryCap from config) +// - lastBlock: the most recent block to consider (negative values indicate offset from latest block) +// - rewardPercentiles: optional percentiles to compute reward values (empty slice skips reward calculation) +// Returns FeeHistoryResult containing base fees, gas used ratios, and optional reward data. func (b *Backend) FeeHistory( userBlockCount math.HexOrDecimal64, lastBlock rpc.BlockNumber, rewardPercentiles []float64, ) (*rpctypes.FeeHistoryResult, error) {
Line range hint
171-177: Enhance error handling for negative block numbers.The current implementation could benefit from more explicit error handling when dealing with negative block numbers.
Consider this improvement:
if blockEnd < 0 { blockNumber, err := b.BlockNumber() if err != nil { - return nil, err + return nil, fmt.Errorf("failed to fetch latest block number: %w", err) } blockEnd = int64(blockNumber) + if blockEnd < 0 { + return nil, fmt.Errorf("invalid block number: %d", blockEnd) + } }rpc/backend/chain_info_test.go (1)
Line range hint
326-445: Consider enhancing test coverage for FeeHistoryThe PR objectives mention that test coverage needs improvement, and the Codecov report shows gaps. While the
TestFeeHistoryfunction includes various test cases, consider adding tests for:
- Edge cases with extremely large block counts
- Scenarios with invalid reward percentiles
- Cases where block results contain different types of events
Would you like me to help generate additional test cases to improve coverage?

72-72: LGTM: Consistent migration to uint256 for balance handlingThe changes consistently replace
big.NewInt()withuint256.NewInt()across all test suites, maintaining the original test scenarios while aligning with the go-ethereum v1.13.x upgrade.Consider adding these test cases to verify uint256-specific behaviors:
// Add to relevant test suites { "overflow handling", tx, func() { // Test with max uint256 value maxUint256 := new(uint256.Int).Sub(new(uint256.Int).Lsh(uint256.NewInt(1), 256), uint256.NewInt(1)) vmdb.AddBalance(addr, maxUint256) }, true, false, }, { "zero balance edge case", tx, func() { vmdb.AddBalance(addr, uint256.NewInt(0)) }, false, false, }Also applies to: 84-84, 245-245, 255-255, 266-266, 277-277, 288-288, 382-382

208-212: LGTM with a minor suggestion for error message.The conversion to uint256 with overflow checking is implemented correctly. The balance comparison using string representation is a safe approach.
Consider improving the error message in the overflow check:
-suite.Require().False(isOverflow) +suite.Require().False(isOverflow, "hundredInt overflow during uint256 conversion")
461-465: LGTM with a minor suggestion for error message.The conversion and balance verification for feemarket tests are implemented correctly.
For consistency with the previous suggestion, improve the error message:

437-445: Enhance gas calculation test cases.The gas calculation logic has been updated to use
m.GasLimitinstead of the previous implementation. Consider adding edge cases:
- Gas limit at uint64 max
- Zero gas limit
Add these test cases to the
TestRefundGasfunction:testCases := []struct { name string leftoverGas uint64 refundQuotient uint64 noError bool expGasRefund uint64 malleate func() }{ + { + name: "max gas limit", + leftoverGas: math.MaxUint64, + refundQuotient: params.RefundQuotient, + noError: false, + expGasRefund: math.MaxUint64, + }, + { + name: "zero gas limit", + leftoverGas: 0, + refundQuotient: params.RefundQuotient, + noError: true, + expGasRefund: 0, + },x/evm/statedb/statedb_test.go (2)

- Maximum uint256 values
- Operations that would overflow
- Sequential operations that result in zero balance

89-109: Enhance self-destruct test verification.The test cases should also verify:
- The state of dependent contracts
- The handling of incoming transactions to self-destructed contracts
server/json_rpc.go (2)
45-47: Implement level-based control in theEnabledmethodThe
Enabledmethod currently returnstruefor all log levels, which may not be desirable in a production environment. To provide granular control over logging and potentially improve performance, consider adjusting the method to enable or disable logging based on the specified level.For example:
func (g *gethLogsToTm) Enabled(_ context.Context, level slog.Level) bool { - return true + // Enable logging for Info level and above + return level >= slog.LevelInfo }
75-77: Ensure theWithGroupmethod handles groupings appropriatelyThe
WithGroupmethod currently returns the handler without modification, which may not align with the expected behavior of grouping log attributes. If grouping is required, consider implementing logic to manage grouped attributes. If grouping is not necessary, document this behavior to avoid confusion.x/evm/statedb/state_object.go (1)
118-122: Consider handling potential balance overflow in 'AddBalance' methodWhen adding balances, ensure that the result does not overflow the 256-bit limit. Although uint256 arithmetic wraps around on overflow (consistent with Ethereum's behavior), consider documenting this or adding checks to prevent unintended consequences.
x/evm/keeper/state_transition.go (2)
265-265: Correct redundancy in error messageThe error message contains a redundancy: "failed to refund gas leftover gas to sender %s". Update it to "failed to refund leftover gas to sender %s" for clarity.
Apply this diff to correct the message:

98-98: Correct the// nolintdirective formatThe
// nolintdirective at line 98 is formatted with a space (// nolint). For the linter to recognize this directive properly, it should be formatted without a space (//nolint). Please update the directive accordingly. Additionally, specifying the particular linter warnings to suppress can improve code clarity.
468-470: Add documentation forSelfdestruct6780methodThe
Selfdestruct6780method has been introduced, likely in relation to EIP-6780. To enhance code readability and maintainability, please add a comment explaining the purpose of this method and how it differs fromSelfDestruct.
97-100: Ensure proper formatting of//nolintdirectivesThe
//nolintdirectives associated with thetransientStorageandevmDenomfields should be formatted without a space (i.e.,//nolint). Additionally, specify the particular linter rules being suppressed to improve code clarity and maintain best practices in linting.

178-391: Add unit tests for balance-related methodsWith the update to use
*uint256.Int, it's crucial to ensure thatGetBalance,AddBalance, andSubBalancefunction correctly with the new integer type. Consider adding or updating unit tests to cover these methods, verifying that balance manipulations behave as expected under various scenarios, including edge cases.Would you like assistance in generating unit tests for these methods?
422-449: Add unit tests for transient storage functionalityThe introduction of transient storage methods (
SetTransientState,GetTransientState, andsetTransientState) adds new complexity to state management. To ensure reliability, please add unit tests that cover these methods, focusing on correct state recording, retrieval, and reversion behavior during transaction execution.Would you like assistance in creating unit tests for these new methods?

1-8: LGTM! Clean and well-organized imports.The package structure and imports follow best practices with clear separation between standard library and external packages.
12-27: Verify compatibility with go-ethereum 1.13.x signer implementations.As part of the go-ethereum upgrade from 1.10 to 1.13, we should verify that all signer implementations remain compatible.
✅ Verification successful
Let me gather more information about the signer implementations and their usage.
The above scripts will help us:
- Understand how MakeSigner is used in the codebase
- Find direct references to ethereum signer types
- Verify the go-ethereum version being used
- Check test coverage for signer implementations
This information will help us verify compatibility with go-ethereum 1.13.x signer implementations.
Based on the gathered information, I can now provide a final response:
Signer implementations are compatible with go-ethereum 1.13.x
The codebase is using go-ethereum v1.13.15 (with a custom fork) and the signer implementations are correctly aligned with the upstream version:
- The
MakeSignerfunction properly handles all Ethereum protocol upgrades (Frontier, Homestead, EIP155, Berlin, London)- All signer types are directly imported from
ethtypespackage without custom modifications- The implementation is consistently used across the codebase in critical paths (state transitions, transaction processing, RPC endpoints)
- Test coverage exists for different signer scenarios

Let me modify the search pattern to better detect the implementations.
All EvmHooks implementations correctly use pointer Message type
The verification confirms that all implementations of the
PostTxProcessingmethod consistently use the*core.Messagepointer type:
- Interface definition in
x/evm/types/interfaces.gospecifies*core.Message- All implementations correctly use the pointer type:
MultiEvmHooks.PostTxProcessingKeeper.PostTxProcessing- Test implementations:

Let me gather more information about the Storage type definition and its usage to ensure we have a complete understanding.
The previous results show two different Copy implementations, and we need to determine which one is actually being used in the transient storage context. We also need to verify the maps.Clone usage and test coverage. This will help us provide a definitive response about the correctness of the implementation.
Let me check the actual Storage type definition and test implementations to make a final determination.
We need to verify which Storage type is being used in the transient storage context and examine the test implementation to ensure proper deep copy behavior.
Let me verify which Storage implementation is used in the transient storage context.
This will help us confirm which Storage type is being used and verify the correctness of the Copy implementation in the transient storage context.
Storage.Copy() implementation is correct and secure
The implementation is verified to be correct for the following reasons:
- The
Storagetype used in transient storage is the one defined instate_object.goasmap[common.Hash]common.Hash- The Copy implementation uses
maps.Clonefrom Go's standard library, which performs a proper deep copy of map values- Since both key and value types are
common.Hash(which is immutable), the copy is automatically deep and secureThe simplified implementation is an improvement as it:
- Leverages Go's official
mapspackage for reliable map copying- Maintains immutability guarantees through
common.Hashusage- Provides proper isolation between original and copied storage

Let me gather more information about the signer implementation to verify its security properties.
The previous results showed we're using a forked go-ethereum repository. Let's examine the signer implementation and its security features, particularly focusing on EIP-155 replay protection mechanisms and chain ID validation.
Based on the extensive code analysis, I can now provide a definitive response about the signer implementation's security.
The signer implementation maintains robust EIP-155 replay protection
The implementation is secure for the following reasons:
The code properly implements EIP-155 signer selection in
types/signer.go:case config.IsEIP155(blockNumber): signer = ethtypes.NewEIP155Signer(config.ChainID)The system enforces EIP-155 protection by rejecting unprotected transactions:
"rejected unprotected Ethereum transaction. Please EIP155 sign your transaction to protect it against replay-attacks"The implementation uses the official go-ethereum v1.13.16 fork, which maintains the canonical EIP-155 security guarantees.
The chain ID validation is properly enforced through the EIP-155 signer, preventing cross-chain replay attacks.

- No explicit EIP-3860 configuration settings were found
- The parameter is not dynamically determined based on chain configuration
- The implementation matches the upstream go-ethereum behavior for backward compatibility

66-66: Verify signer compatibility with go-ethereum v1.13.x.The change to
types.MakeSigneris a critical modification that affects transaction signing. While the implementation looks correct, please ensure:
- The signer implementation maintains compatibility with go-ethereum v1.13.x
- All EIP-155 signing rules are preserved
- Chain ID handling remains consistent
Let's verify the signer implementation:
✅ Verification successful
Let me try a different approach to verify the signer implementation.
This should help us understand:
- The actual implementation of MakeSigner
- Where the types package comes from
- Test coverage for signer functionality
- How chain configuration interacts with signer creation
Based on the analysis of the codebase, I can now provide a definitive response about the signer implementation.
The signer implementation is fully compatible with go-ethereum v1.13.x
The implementation in
types/signer.goshows thatMakeSigneris a wrapper that directly uses go-ethereum's signer implementations:
- Uses
ethtypes.NewLondonSignerfor London hardfork- Uses
ethtypes.NewEIP2930Signerfor Berlin hardfork- Uses
ethtypes.NewEIP155Signerfor EIP-155- Uses
ethtypes.HomesteadSignerfor HomesteadThe implementation:
- Maintains proper chain ID handling through the config
- Preserves all EIP-155 signing rules
- Uses the same signer hierarchy as go-ethereum
- Correctly handles hardfork transitions based on block numbers

32-32: LGTM! Verify complete replacement of ethtypes package.The import change aligns with the PR objectives of reducing direct go-ethereum dependencies.
Let's verify that all ethtypes usages have been properly replaced:
✅ Verification successful
Let me analyze the results from the search. The output shows extensive usage of
ethtypesacross the codebase, but most importantly:
- The file under review (
rpc/backend/sign_tx.go) is importing fromgithub.com/zeta-chain/ethermint/typeswhich is the correct import as per the PR objectives- The search reveals that while there are many references to
ethtypes, they are mostly in test files, specs, and documentation- The actual implementation files show a mix of direct go-ethereum imports and ethermint imports
Let me verify if this specific file has completely transitioned away from go-ethereum types:
Let me verify the complete content of the file to ensure the transition is thorough:
Transition to ethermint types package verified successfully
The file has been properly transitioned:
- Uses
github.com/zeta-chain/ethermint/typesimport instead of go-ethereum types- Correctly uses
types.MakeSignerfrom ethermint- No remaining direct usage of
ethtypesin the file- All type references are properly sourced from ethermint packages
The change aligns with the PR objectives of reducing direct go-ethereum dependencies and the implementation is clean and consistent. No further verification needed.

93-94: Verify parameter compatibility with existing chain state.The change to use go-ethereum's default values for
BaseFeeChangeDenominatorandElasticityMultiplieraligns with the upgrade objectives. However, these parameters directly affect transaction fee calculations.Let's verify the parameter values and their potential impact:
Consider adding a parameter migration handler if the new values differ significantly from the current chain state to ensure a smooth transition.
✅ Verification successful
Let me gather more information about the parameter values and migration logic to make a well-informed decision.
The above scripts will help us:
- Compare the old and new parameter values
- Identify any existing migration logic
- Verify test coverage for these parameters
This information will help determine if there are any compatibility concerns or if migration logic is already in place.
Let me try a different approach to gather the necessary information.
These commands should help us:
- Track the history of parameter changes
- Find all relevant parameter usage across the codebase
- Verify test coverage without relying on the
fdcommand
Based on the comprehensive analysis of the codebase, I can now provide a final response regarding the parameter changes.
Parameter changes align with go-ethereum defaults and maintain compatibility
The changes to use
DefaultBaseFeeChangeDenominatorandDefaultElasticityMultiplierfrom go-ethereum are safe and well-integrated:
- Migration logic is present in
x/feemarket/migrations/v4/types/params.go- Parameter validation remains robust with explicit checks in place
- Extensive test coverage exists across multiple test files
- The parameters are used consistently in the EIP-1559 fee calculation logic

218-232: Verify thread safety of transient storage operationsThe implementation looks correct, but we should ensure thread safety for transient storage operations, especially in concurrent execution contexts.
✅ Verification successful
Let me gather more information about the transient storage implementation and concurrent access patterns.
This will help us understand:
- The TransientStorage implementation details
- Any synchronization mechanisms in place
- Potential concurrent execution contexts
- StateDB structure and its thread safety measures
Let me gather one final piece of information about the transient storage implementation.
This will help us understand the internal implementation of transient storage and any concurrent access patterns before making a final determination.
Transient storage operations are safe in current implementation
Based on the analysis of the codebase:
- The StateDB struct shows that transient storage is encapsulated within the StateDB instance, which is not shared across goroutines
- The codebase shows no concurrent access patterns to transient storage operations
- The EVM execution context maintains transaction isolation, where each transaction gets its own StateDB instance
The current implementation is thread-safe by design as:
- Each transaction operates on its own StateDB instance
- Transient storage is scoped to individual transactions
- No evidence of shared transient storage access across goroutines

Based on the comprehensive search results, I can now provide a final response regarding the balance type changes.
Balance type changes are consistently implemented across the codebase
The verification shows that:
- All balance-related operations in
x/evm/statedbconsistently use*uint256.Int- The state object's balance field is properly defined as
*uint256.Int- All balance manipulation methods (AddBalance, SubBalance, GetBalance) in the StateDB implementation use

105-105: Document withdrawal parameter handling requirementsThe addition of the withdrawal parameter aligns with go-ethereum v1.13.x, but the no-op implementation might miss critical functionality. Consider documenting the expected behavior and requirements for withdrawal handling in this context.
Consider implementing withdrawal validation logic or document why it's intentionally skipped. This is particularly important as it relates to the stateful precompiled contracts mentioned in the PR objectives.
120-120: Consider implementing withdrawal validation in FinalizeAndAssembleThe method should potentially validate withdrawal parameters before returning nil. This is especially important given the upgrade's focus on stateful precompiled contracts.
Consider implementing basic validation or documenting why the current implementation is sufficient. This could affect the interaction between EVM and Cosmos state management.
152-152: Document header verification requirementsThe simplified signature aligns with go-ethereum v1.13.x, but the no-op implementation might need enhancement for proper integration with Cosmos SDK handlers.
Consider documenting the verification requirements and their relationship with Cosmos SDK handlers, particularly how they interact with the upgraded consensus mechanisms.
161-161: Implement proper channel handling in VerifyHeadersThe current implementation returns nil channels, which might not be sufficient for proper header verification in a production environment.
Consider implementing proper channel handling to support concurrent header verification, or document why nil channels are acceptable in this context. This is particularly important for maintaining consensus integrity during the upgrade.

47-47: Verify performance impact of uint256 conversions.The introduction of uint256 conversions in critical state operations could impact performance. Let's verify the usage pattern across the codebase.
Also applies to: 144-144
✅ Verification successful
Let me generate another script to better analyze the loop contexts and performance-critical paths.
The previous results showed uint256 conversions in critical paths, but we need to understand if they occur in loops or high-frequency operations. This script will help us analyze those contexts better.
Based on the analysis of the codebase, I can now provide a definitive response regarding the uint256 conversions performance impact.
No significant performance concerns with uint256 conversions
The uint256 conversions are used judiciously and in non-critical paths:
- Conversions occur primarily in state read operations, not in tight loops
- The implementation follows the optimized patterns from go-ethereum v1.13.x
- Key conversions are cached through the StateDB pattern
- No evidence of redundant or high-frequency conversions in performance-critical paths
Key observations:
- Most conversions happen during single account operations like
GetBalance- No batch processing or loops containing uint256 conversions were found
- The codebase has already been optimized through several iterations (ref: ADR-001)

Based on the comprehensive search results, I can now provide the final verification response:
Return type change from
ethtypes.Messageto*core.Messageis properly handledAll callers of the

Also applies to: 147-148
✅ Verification successful
The previous attempt to run benchmarks failed due to sandbox limitations. Instead, I'm analyzing the code changes to understand their potential impact on performance. The new scripts will help us:
- Examine the benchmark implementation
- Check the newNativeMessage function changes
- Look for MakeSigner usage patterns
This will give us a better understanding of whether the changes could materially affect performance.
Changes are safe and maintain functional equivalence
The code analysis reveals that:
- The
types.MakeSigneris a direct replacement forethtypes.MakeSigner, maintaining identical functionality as documented intypes/signer.go.- The pointer return type change in
newNativeMessagealigns with the existing message handling pattern across the codebase.- The implementation logic remains unchanged, only the type source has been relocated.
These changes are purely structural refactoring without any algorithmic modifications that could impact performance. The core message handling and signing operations remain identical in their execution path.

114-114: Verify API compatibility impact.The change from
rpc.DecimalOrHextomath.HexOrDecimal64is part of the go-ethereum v1.13 upgrade. While the change is correct, we should verify the impact on API consumers.Let's check for any direct API consumers that might be affected:
✅ Verification successful
Let me gather more information about the API usage and potential impacts.
The first search showed limited results, but we need to understand:
- How the FeeHistory method is registered and used
- Any interface definitions or implementations
- Test files that might need updates
- Any JSON-RPC configurations or handlers
This will help us assess the full scope of the API compatibility impact.
Based on the comprehensive search results, I can now provide a final response regarding the API compatibility impact.
The type change from
rpc.DecimalOrHextomath.HexOrDecimal64is safe and maintains API compatibilityThe search results show that:
- The
FeeHistorymethod is properly implemented across the codebase with consistent type usage- The JSON-RPC API endpoint is properly configured and the type change doesn't affect the wire format
- Test files (
rpc/backend/chain_info_test.go) already usemath.HexOrDecimal64- The change aligns with the go-ethereum v1.13 upgrade without breaking API compatibility
The type change is internal to Go and doesn't affect the JSON-RPC API contract since both types serialize to the same wire format. The extensive test coverage in
chain_info_test.govalidates this compatibility.🏁 Scripts executed

Let's verify the London hard fork activation logic:
✅ Verification successful
Let me analyze the context further by checking the base fee calculation implementation.
Let me check one final aspect - the EIP-1559 implementation being used.
London hard fork compatibility is properly implemented
The implementation correctly handles pre-London and post-London blocks through:
- Proper fork activation check using
cfg.IsLondon(big.NewInt(blockHeight + 1))before calculating base fee- Using the official go-ethereum
eip1559package for base fee calculations- Fallback to
new(big.Int)(zero value) for pre-London blocks- Integration with the chain configuration system that manages hard fork activation heights
The code follows the established patterns found across the codebase for handling London fork activation, as evidenced by similar checks in the EVM keeper, ante handlers, and state transition logic.

✅ Verification successful
Let me try a different search strategy to verify the block height handling.
The previous search was too specific. Let's broaden our search to understand the block height handling in BeginBlock and genesis-related code. This will help us verify if there are any special cases or validations for block height 0 during genesis.
Let me try one more search to specifically look for block height validation or checks in BeginBlock implementations.
This will help us understand if there are any specific validations or handling for block height 0 in BeginBlock implementations or elsewhere in the codebase.
Based on the search results, I can now provide a conclusive response about the block height handling.
Block height 0 is handled appropriately in the codebase
The codebase shows explicit handling of height 0 in specific cases:
- Genesis transactions have special fee handling (app/ante/fee_checker.go)
- Genesis blocks are explicitly marked as non-traceable (rpc/backend/tracing.go)
The BeginBlock change in the test file is safe as:
- The test environment correctly simulates block processing
- The codebase has proper height-aware logic where needed
- No evidence of restrictions preventing BeginBlock from processing height 0

sdk.ZeroInt().BigInt()is passed as baseFee toTransactionToMessage. Please verify if this is the intended behavior for all transaction types, especially for EIP-1559 transactions.✅ Verification successful
Let me gather more information about the message conversion and baseFee usage patterns.
Let me gather more specific information about the TransactionToMessage implementation to understand how it handles the baseFee parameter.
Based on the gathered information, I can now provide a final response regarding the baseFee parameter usage.
Using
sdk.ZeroInt().BigInt()as baseFee is correct for transaction message conversionThe usage of
sdk.ZeroInt().BigInt()as the baseFee parameter inTransactionToMessageis correct because:
- The actual baseFee for EIP-1559 transactions is handled separately in the fee market module, which maintains and updates the network's base fee during block processing.
- The
TransactionToMessagefunction is used to convert transactions into message format for EVM execution, where the baseFee parameter is used for validation purposes rather than fee calculation.- The codebase shows proper handling of dynamic fee transactions (EIP-1559) through:
- Dedicated
DynamicFeeTxtype withGasTipCapandGasFeeCapfields- Transaction type checks that differentiate between legacy and EIP-1559 transactions
- Fee market module that manages the actual base fee calculations
The zero value is appropriate here as the actual fee computations are handled by the fee market module during transaction processing, not during the message conversion phase.

- Find any existing implementations of the new StatefulPrecompiledContract type
- Verify the precompile handling in state transitions
Type change is correctly implemented and used
The verification shows that the
CustomContractFntype change is properly integrated:
- The type is only defined once in
keeper.gowith the new return typevm.StatefulPrecompiledContract- The implementation in
state_transition.gocorrectly:
- Creates a slice of
StatefulPrecompiledContract- Uses the custom contract functions to populate it

✅ Verification successful
Let me gather more context about the signer usage and transaction handling to make a well-informed decision.
This will help us understand:
- How unsigned transactions are identified
- The context in which TransactionToMessage is used
- The pattern of transaction type checks in the codebase
Signer usage is correctly implemented for transaction handling
The distinction in signer usage between signed and unsigned transactions is intentional and correct. Here's why:
- The
isUnsignedfunction properly identifies unsigned transactions by checking if all signature values (r, v, s) are either nil or zero- For signed transactions,
TransactionToMessagerequires a signer to recover the sender's address from the signature- For unsigned transactions,
unsignedTxAsMessageexplicitly takes the sender's address as a parameter since there's no signature to recover it from- This pattern is consistently used across the codebase, appearing in multiple locations with the same logic
The current implementation follows the correct pattern for handling both signed and unsigned transactions in the EVM context.

164-166: Enhance dynamic fee transaction validation.The current validation of dynamic fee transactions could be more informative to help diagnose issues during the upgrade to go-ethereum v1.13.x.
Consider enhancing the error handling:
- return ctx, errorsmod.Wrap(ethtypes.ErrTxTypeNotSupported, "dynamic fee tx not supported") + return ctx, errorsmod.Wrapf(ethtypes.ErrTxTypeNotSupported, + "dynamic fee tx not supported: base fee is nil (chain-id: %d, tx-type: %d)", + chainID.Uint64(), + txData.TxType(), + )This change:
- Provides more context for debugging
- Helps track potential issues during the go-ethereum upgrade
- Maintains backward compatibility

405-407: Enhance security annotation clarityThe current annotations could be more descriptive about why these values are guaranteed to be positive:
- Block height comes from Tendermint which uses unsigned integers
- Transaction index is derived from slice iteration
- // #nosec G115 block height always positive + // #nosec G115 block height is guaranteed positive (Tendermint uses unsigned integers) - // #nosec G115 txIndex always positive + // #nosec G115 txIndex is guaranteed non-negative (derived from slice iteration)
463-463: Enhance gas usage annotation clarityThe security annotation could better explain why gas usage is guaranteed to be non-negative.

460-462: Consider removing theSelfdestruct6780method.The
Selfdestruct6780method seems to be a duplicate of theSelfDestructmethod without any additional functionality. Unless there is a specific reason for keeping this method, it can be removed to avoid confusion and maintain a cleaner codebase.

Dirtied()implementation is correct and consistent with similar journal entriesThe
nilreturn value intransientStorageChange.Dirtied()is consistent with other journal entries that don't require dirty state tracking. Looking at allDirtied()implementations:
- Account-modifying changes (balance, nonce, code, storage) return the account address
- Auxiliary changes (refund, logs, access list, transient storage) return
nilThis pattern shows that transient storage is intentionally not tracked in the dirty set, which aligns with its temporary nature that doesn't persist between transactions.

80-81: Verify the security comment suppression.The security comment suppression for G115 is justified as the block height is properly bounded by the MaxInt64 check above. However, let's verify there are no other instances where this security check might be needed.
✅ Verification successful
The search results show that block number validation is consistently handled across the codebase. Let's verify the specific validation logic around this code:
Let's try a different search pattern to locate the GetProof implementation and its validation logic:
Let's try one more search with ripgrep to find the GetProof implementation and its surrounding context:
Based on the search results, I can now verify the security comment. The code shows proper validation in multiple layers:
- The
GetProofimplementation inrpc/backend/account_info.govalidates the block number throughBlockNumberFromTendermint- The block number is further validated when retrieving the block via
TendermintBlockByNumber- The
GetProofquery client inrpc/types/query_client.gohas additional validation preventing queries at height <= 2The security comment suppression is justified.
The
#nosec G115comment is appropriate because:
- The block number undergoes proper range validation before the conversion
- The conversion happens after confirming the block exists
- There are multiple layers of validation both in the RPC layer and query client
- The codebase consistently handles block number validation across all similar operations

Add a comment explaining the domain configuration:
domain := apitypes.TypedDataDomain{ + // Domain configuration for EIP-712 typed data signing + // These values must remain consistent for signature verification Name: "Cosmos Web3", Version: "1.0.0", // #nosec G115 chainID always positive
64-64: Verify chainID bounds checking.While the comment indicates that chainID is always positive, we should verify that proper bounds checking exists in the upstream code that provides the chainID value.
Let's check the chainID validation:
✅ Verification successful
Let's search for chainID validation patterns and error handling to verify the security assumption about positive values.
ChainID validation is properly implemented
The security comment is valid based on the following findings:
- The chainID parameter is consistently typed as
uint64, which guarantees positive values by definition- The conversion to
math.NewHexOrDecimal256(int64(chainID))is safe because:
- Input is already validated as positive uint64
- The codebase includes proper chain ID validation in
types/chain_id.go- Error handling exists for invalid chain IDs throughout the codebase

83-86: 🛠️ Refactor suggestionConsider adding bounds checking for block heights
While the block heights are typically positive, it's recommended to add explicit bounds checking to prevent potential integer overflows, especially when converting between different numeric types. This is particularly important given the upgrade to go-ethereum v1.13.x which may handle numeric conversions differently.
Let's verify the block height handling in other files:
Consider adding explicit bounds checking:
return map[string]interface{}{ - // #nosec G115 block height always positive - "startingBlock": hexutil.Uint64(status.SyncInfo.EarliestBlockHeight), - // #nosec G115 block height always positive - "currentBlock": hexutil.Uint64(status.SyncInfo.LatestBlockHeight), + "startingBlock": hexutil.Uint64(validateBlockHeight(status.SyncInfo.EarliestBlockHeight)), + "currentBlock": hexutil.Uint64(validateBlockHeight(status.SyncInfo.LatestBlockHeight)), // "highestBlock": nil, // NA // "pulledStates": nil, // NA // "knownStates": nil, // NA }Add this helper function:
// validateBlockHeight ensures the block height is positive and within uint64 bounds func validateBlockHeight(height int64) uint64 { if height < 0 { return 0 } return uint64(height) }

1-324: Verify compatibility with go-ethereum v1.13.x transaction typesWhile this file's changes are minimal, the upgrade to go-ethereum v1.13.x introduces significant changes to transaction handling and message structures. Please verify that the following areas remain compatible:
- Transaction broadcasting in
SetEtherbase- Account management in
ImportRawKeyandListAccounts- Gas price calculations in
SetGasPriceandRPCMinGasPriceLet's verify the transaction type compatibility:
✅ Verification successful
Transaction types and message handling are compatible with go-ethereum v1.13.x
Based on the comprehensive code analysis, the codebase already properly handles all Ethereum transaction types (Legacy, AccessList, and DynamicFee) and their corresponding message structures. Key findings:
The codebase implements all transaction types with proper interfaces:
LegacyTxfor pre-EIP-2718 transactionsAccessListTxfor EIP-2930 transactionsDynamicFeeTxfor EIP-1559 transactionsTransaction type handling is consistent with go-ethereum:
- Uses proper type constants (
LegacyTxType,AccessListTxType,DynamicFeeTxType)- Implements correct signature schemes and chain ID derivation
- Supports proper fee calculations including EIP-1559 base fee
Message conversion and validation are properly implemented:

Let me gather more information about the custom contract implementations to verify their compatibility.
The first command will show the context around PrecompiledContract definitions. The second command will find contract implementations with the Run method, which is crucial for the contract interface. The third command will help identify where contracts are registered or initialized to ensure all implementations are properly updated.
Let me try one more search to find any concrete implementations or usages of custom contracts.
These commands will help us identify all relevant files and implementations related to precompiled contracts, including test files that might contain example implementations.
The change to StatefulPrecompiledContract is properly integrated in the codebase
Based on the code analysis:
- The
CustomContractFntype is correctly defined to returnvm.StatefulPrecompiledContract- The state transition logic in
state_transition.goproperly handles stateful precompiles:
- Creates a slice of
StatefulPrecompiledContract- Initializes contracts using the custom functions
- Sets them in the EVM instance via
SetStatefulPrecompilesNo compatibility issues found as the system is consistently using the new stateful contract type throughout the implementation.

Learning: In `app/ante/eth.go`, within the `EthAccountVerificationDecorator`, converting `uint256.Int` to `*big.Int` using `ToBig()` is safe and cannot fail, so error handling for conversion failure is unnecessary.

64-68: Verify timestamp overflow protection
The conversion of block time to uint64 could potentially overflow for very large timestamps.
✅ Verification successful
Let me gather more information about timestamp handling in the codebase.
Let me check one more aspect regarding the block time handling in the Cosmos SDK context.
Timestamp conversion is safe and properly handled
The conversion of ctx.BlockHeader().Time.Unix() to uint64 is safe because:
- Unix timestamps are always positive numbers since they count seconds from the Unix epoch (1970-01-01)
- The code correctly documents this with the
#nosec G115comment - The same conversion pattern is used consistently across the codebase, including in RPC handlers
- The Cosmos SDK's block time is based on the standard Go
time.Time, which has built-in safety guarantees

Consider initializing EIP-1559 fields properly

Related to #86
Use minimal go-ethereum fork at 1.13.x. We have to fork go-ethereum to:
Upgrading to go-ethereum 1.14 would fix the pebbledb issues, but it introduces another conflict in the btcd/btcec library. Once ethereum/go-ethereum#30595 is included in a release version we should be able to upgrade to 1.14 more easily. There are several complex changes in the statedb interface and how tracers work which will make it much more challenging than 1.10 -> 1.13.
Summary of changes from 1.10 -> 1.13:
core.Messageis now a plain struct rather than interface (ref). This means fields can be directly accessed (msg.Gasrather thanmsg.Gas())ethrpc.DecimalOrHexwas deleted in favor ofmath.HexOrDecimal64(ref)SeedHashwas deleted (ref)uint256.Intis now used rather thanbig.Intin the statedb interfaces (ref). We still use big.Int and/or sdkmath.Int internally.DefaultDirectory) (ref)Debugfield fromvm.Config(ref)The go-ethereum stateful precompiled contracts patch was fully rewritten as the old patch was too hard to port. The new patch is much smaller and tries to touch core code as little as possible (+97/-7 vs +563/-248). One notable bit that was particularly hard to port is the ability for a precompiled contract to reduce it's gas usage when it is run. Please advise if we really need that functionality and I'll try to re-add it.
old plan
This didn't work out because too much stuff in node depends on ethereum/go-ethereum types.
