: Consider specifying the Compose file version.While optional in recent Docker Compose versions, it's good practice to specify the version for clarity and compatibility. Consider adding
version: "3.8"
or the appropriate version you're targeting.+version: "3.8" name: "reth" services:

: Architecture Review: Solid foundation with room for enhancement.The
EngineAPIExecutionClient
implementation follows good design principles:
- Uses the decorator pattern effectively
- Provides clear separation of concerns
- Maintains good documentation
For future iterations, consider:
- Adding observability (logging, metrics, tracing)
- Implementing graceful shutdown mechanisms
- Adding health checks and readiness probes
- Documenting error scenarios and recovery strategies

: Remove unused JWT-related constant.The
jwtSecretFile
constant is defined but never used in the test suite.
21-28
: Remove unused field from testEnv struct.The
jwtSecret
field is initialized as empty and never used in the test suite.
54-56
: Consider making URLs configurable.The eth and engine URLs are hardcoded. Consider making these configurable through test constants or environment variables for better test environment flexibility.
- ethURL := "http://localhost:8545" - engineURL := "http://localhost:8551" + ethURL := os.Getenv("TEST_ETH_URL") + if ethURL == "" { + ethURL = "http://localhost:8545" + } + engineURL := os.Getenv("TEST_ENGINE_URL") + if engineURL == "" { + engineURL = "http://localhost:8551" + }
72-76
: Add error handling in cleanup function.The cleanup function should handle potential errors during cleanup operations.
cleanup: func() { - cleanup() - testServer.Close() - proxyClient.Stop() + if err := os.RemoveAll(tmpDir); err != nil { + t.Errorf("failed to cleanup temp dir: %v", err) + } + testServer.Close() + if err := proxyClient.Stop(); err != nil { + t.Errorf("failed to stop proxy client: %v", err) + } },
1-162
: Consider enhancing test infrastructure for better maintainability.While the test suite provides good basic coverage, consider these architectural improvements:
- Create a separate test configuration package to manage test constants and environment variables
- Implement a test helper package for common setup and assertion functions
- Add table-driven tests for better coverage of edge cases
- Consider using a test fixture pattern for complex test scenarios
This will improve maintainability and make it easier to add new test cases as the execution client evolves.

: Consider pruning unnecessary indirect dependenciesThe
go.mod
file includes a large number of indirect dependencies. While some may be necessary, consider reviewing and pruning any unnecessary indirect dependencies. This can reduce the module's size and potential security vulnerabilities.proxy/client.go (5)
80-100
: Use strongly typed structs instead of 'map[string]interface{}'In the
InitChain
method, you're usingmap[string]interface{}
forforkchoiceResult
andpayload
variables. This approach can introduce type assertions and potential runtime errors.Consider defining Go structs that match the expected JSON-RPC response payloads. This will:
- Improve type safety by catching mismatches at compile time.
- Enhance code readability and maintainability.
- Reduce the need for type assertions throughout your code.
For example:
type ForkchoiceUpdatedResult struct { PayloadID string `json:"payloadId"` } type Payload struct { StateRoot string `json:"stateRoot"` GasLimit uint64 `json:"gasLimit"` // Add other relevant fields }Then, modify your code to unmarshal responses into these structs.
112-142
: Handle large transaction pools efficientlyIn the
GetTxs
method, you are iterating over all pending and queued transactions:for _, accountTxs := range result.Pending { for _, tx := range accountTxs { // ... } }While this works for small numbers of transactions, large transaction pools may impact performance and memory usage.
Consider implementing pagination or limiting the number of transactions processed to handle scalability more effectively.
152-163
: Extract common logic for 'engine_forkchoiceUpdatedV1' callsThe code for invoking
engine_forkchoiceUpdatedV1
is similar in bothInitChain
andExecuteTxs
methods.To improve code reusability and reduce duplication, consider extracting this logic into a helper function. For example:
func (p *ProxyClient) updateForkChoice(ctx context.Context, headBlockHash common.Hash, payloadAttributes map[string]interface{}) (string, error) { var result map[string]interface{} err := p.engineClient.CallContext(ctx, &result, "engine_forkchoiceUpdatedV1", map[string]interface{}{ "headBlockHash": headBlockHash, "safeBlockHash": headBlockHash, "finalizedBlockHash": headBlockHash, }, payloadAttributes, ) if err != nil { return "", fmt.Errorf("engine_forkchoiceUpdatedV1 failed: %w", err) } payloadID, ok := result["payloadId"].(string) if !ok { return "", ErrNilPayloadStatus } return payloadID, nil }Then, you can call this helper function in both methods:
// In InitChain payloadID, err := p.updateForkChoice(ctx, p.genesisHash, /* payload attributes */) // In ExecuteTxs payloadID, err := p.updateForkChoice(ctx, common.BytesToHash(prevStateRoot[:]), /* payload attributes */)
183-185
: Improve error handling for payload status checksIn the
ExecuteTxs
method, when checking the payload status:status, ok := newPayloadResult["status"].(string) if !ok || PayloadStatus(status) != PayloadStatusValid { return rollkitTypes.Hash{}, 0, ErrInvalidPayloadStatus }Consider providing more detailed error messages to assist in debugging. If the payload status is invalid, including the received status in the error can be helpful.
Apply this diff to enhance the error message:
if !ok || PayloadStatus(status) != PayloadStatusValid { - return rollkitTypes.Hash{}, 0, ErrInvalidPayloadStatus + return rollkitTypes.Hash{}, 0, fmt.Errorf("invalid payload status: %v", status) }

: Consider enhancing the implementation for production readiness.
While the current implementation correctly delegates to the underlying executor, consider the following improvements for production use:
- Add context support for cancellation and timeouts
- Add input validation
- Add logging and metrics for monitoring
Example enhancement for the ExecuteTxs method:
func (c *EngineAPIExecutionClient) ExecuteTxs(
+ ctx context.Context,
txs []rollkitTypes.Tx,
blockHeight uint64,
timestamp time.Time,
prevStateRoot rollkitTypes.Hash,
) (rollkitTypes.Hash, uint64, error) {
+ if len(txs) == 0 {
+ return rollkitTypes.Hash{}, 0, fmt.Errorf("no transactions provided")
+ }
+ if timestamp.IsZero() {
+ return rollkitTypes.Hash{}, 0, fmt.Errorf("invalid timestamp")
+ }
+
+ // Add logging
+ logger := log.With().
+ Uint64("blockHeight", blockHeight).
+ Time("timestamp", timestamp).
+ Int("txCount", len(txs)).
+ Logger()
+ logger.Debug().Msg("executing transactions")
+
+ // Add metrics
+ defer func(start time.Time) {
+ metrics.ExecutionDuration.Observe(time.Since(start).Seconds())
+ }(time.Now())
+
- return c.execute.ExecuteTxs(txs, blockHeight, timestamp, prevStateRoot)
+ return c.execute.ExecuteTxs(ctx, txs, blockHeight, timestamp, prevStateRoot)
}

: Ensure block retrieval handles nil blocks
In the SetFinal
method, when retrieving the block by number:
block, err := p.ethClient.BlockByNumber(ctx, big.NewInt(int64(height)))
if err != nil {
return fmt.Errorf("failed to get block at height %d: %w", height, err)
}
There's a possibility that the block at the given height does not exist, resulting in block
being nil
. Ensure that block
is not nil
before proceeding.
Verification Script:
#!/bin/bash
# Description: Verify that 'BlockByNumber' properly handles non-existent blocks.
# Test: Attempt to retrieve a block at a future height.
# Expect: The function returns an error and does not panic.
# Replace <FUTURE_HEIGHT> with a block number greater than the current chain height.

:
Fix undefined reference to 'execution.Execute'
At line 33, the code attempts to ensure that ProxyClient
implements the Execute
interface:
var _ execution.Execute = (*ProxyClient)(nil)
However, the compiler error indicates that execution
is undefined. This suggests that the execution
package does not expose an Execute
interface, or the package is not correctly imported.
To resolve this issue:
-
Verify the import path: Ensure that the
execution
package is correctly imported and that it provides theExecute
interface. -
Check the package contents: It's possible that the interface is named differently or resides in a subpackage.
Verification Script:
To verify the available interfaces in the execution
package, run the following script:
This script will list all interfaces defined in the go-execution
package, allowing you to confirm the correct interface name and adjust the code accordingly.

🛠️ Refactor suggestion
Consider improving the constructor implementation.
The current implementation has a few areas for improvement:
- The constructor returns an error but never uses it
- The
execute
parameter should be validated for nil
Consider applying this change:
func NewEngineAPIExecutionClient(execute execution.Execute) (*EngineAPIExecutionClient, error) {
+ if execute == nil {
+ return nil, fmt.Errorf("execute implementation is required")
+ }
return &EngineAPIExecutionClient{

🛠️ Refactor suggestion
Add negative test cases for InitChain.
The test only covers the happy path. Consider adding test cases for:
- Invalid chain ID
- Zero genesis time
- Mock returning an error
Also, consider making the chain ID a named constant:
- chainID := "11155111" // sepolia chain id

🛠️ Refactor suggestion
Enhance ExecuteTxs test coverage.
The test should include additional scenarios:
- Empty transaction list
- Invalid previous state root
- Multiple transactions
- Large transactions that might hit size limits
- Transactions that would exceed block gas limit
Also, consider making the gas values constants:

: Imports look good!
The import aliases are consistently formatted in lowercase, addressing the previous review comment.

: Consider moving the implementation logic to EngineAPIExecutionClient
.
As suggested in the previous review, it might be better to implement the core logic directly in the EngineAPIExecutionClient
struct and have the ProxyClient
delegate to it. This would promote a cleaner separation of concerns and make the ProxyClient
a thinner wrapper around the execution client.

: Properly close connections in the Stop
method.
The previous review comment about closing engineClient
and ethClient
connections has been addressed. The Stop

: Verify error handling for payload status.
The ExecuteTxs
method handles errors related to nil and invalid payload statuses. Please verify that this error handling is sufficient and covers all necessary scenarios.
Run the following script to verify the error handling:
✅ Verification successful
Let me gather more information about the payload status handling by checking the PayloadStatus type and its possible values.
Error handling for payload status is comprehensive and correct
The error handling for payload status in ExecuteTxs
is sufficient and properly implemented:
- It correctly handles nil payload status by returning
ErrNilPayloadStatus
when the payload ID type assertion fails - It properly validates the payload status by checking both the type assertion and value comparison against all possible states (
VALID
,INVALID
,SYNCING
) - It returns
ErrInvalidPayloadStatus
for any non-VALID
status, which is the correct behavior as onlyVALID
payloads should proceed - The error types are properly defined and exported for external error handling
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:

Set secure file permissions for JWT token.
The JWT token file needs restricted permissions since it's used for authentication. Add chmod 600
to ensure only the owner can read/write the file.

Implement proper logic for deriving prevRandao
.
The current implementation of derivePrevRandao
is a placeholder that simply returns the block height as a hash. This needs to be updated with the correct logic for deriving the prevRandao
value.
Do you want me to generate the code for deriving the prevRandao
value or open a GitHub issue to track this task?

: Consider using strongly-typed structs for JSON-RPC responsesRelying on
map[string]interface{}
and type assertions can be error-prone and may lead to runtime panics due to unexpected data formats.Define structs that match the expected response formats to enhance type safety and code readability. For example:
type ForkchoiceUpdatedResult struct { PayloadID string `json:"payloadId"` } type PayloadAttributes struct { Timestamp uint64 `json:"timestamp"` PrevRandao common.Hash `json:"prevRandao"` SuggestedFeeRecipient common.Address `json:"suggestedFeeRecipient"` } type ExecutionPayload struct { StateRoot string `json:"stateRoot"` GasLimit uint64 `json:"gasLimit"` // Add other relevant fields }Then, use these structs when making RPC calls:
var forkchoiceResult ForkchoiceUpdatedResult err := c.engineClient.CallContext(ctx, &forkchoiceResult, "engine_forkchoiceUpdatedV1", forkchoiceState, payloadAttributes)This approach reduces the risk of runtime errors and makes the codebase easier to maintain.

Prevent integer overflow when converting blockHeight
In derivePrevRandao
, converting blockHeight
from uint64
to int64
can cause an integer overflow if blockHeight
exceeds MaxInt64
, leading to incorrect behavior.
Use new(big.Int).SetUint64(blockHeight)
to safely handle the conversion:
func (c *EngineAPIExecutionClient) derivePrevRandao(blockHeight uint64) common.Hash {

: Consider using table-driven tests.
The test functions could benefit from using table-driven tests to make it easier to add new test cases and improve maintainability. This would also make it simpler to implement the additional test scenarios mentioned in the previous review comments.
Example structure:
func TestEngineAPIExecutionClient_InitChain(t *testing.T) {
tests := []struct {
name string
genesisTime time.Time
height uint64
chainID string
wantRoot rollkit_types.Hash
wantGas uint64
wantErr bool
}{
// Add test cases here
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
env := setupTestEnv(t)
defer env.cleanup()
// Test implementation
})
}
}
Skipping generation of comments about adding negative test cases as they were already mentioned in previous reviews and are still valid.

💡 Codebase verification
Security review of cryptographic dependencies required
Based on the analysis of the security-critical dependencies, immediate attention is needed:
- btcd/btcec v2.3.4 is significantly behind the latest v0.24.2 release and has a high severity security advisory related to "OP_CODESEPARATOR fuzzy match"
- gnark-crypto v0.12.1 is behind the latest v0.14.0 release and has a known low severity issue affecting exponentiation operations
- Both repositories show active maintenance with recent commits, but security issues exist
Action items:
- Upgrade btcd/btcec to latest v0.24.2 to address the high severity security issue
- Consider upgrading gnark-crypto to v0.14.0 which may include security improvements
- Review the impact of the known gnark-crypto exponentiation issue on your implementation
🔗 Analysis chain
Verify versions of security-critical dependencies
Several security-critical dependencies are included. Please ensure these versions have no known vulnerabilities:
- btcd/btcec/v2 v2.3.4 (cryptographic operations)
- gnark-crypto v0.12.1 (cryptographic primitives)
- go-kzg-4844 v1.0.0 (trusted setup)
Let me gather more information about the security aspects of these dependencies.

💡 Codebase verification
Remove unused JWT constant
The jwtSecretFile
constant is not being used in the codebase. While there is a jwtSecret
field in the testEnv
struct, it's only initialized as an empty string and the jwtSecretFile
constant is never referenced. The constant can be safely removed.
🔗 Analysis chain
Verify if the JWT secret file constant is needed.
The constant jwtSecretFile
is currently unused. If it's intended for future JWT authentication implementation, consider adding a TODO comment explaining its purpose or remove it if not needed.
Let me gather more context about the JWT usage in the codebase.
Let me check if this JWT-related code is used in any test cases or if there are any other files that might be using this constant.

💡 Codebase verification
Dependency replacement requires attention
Based on the verification results:
- The fork is correctly linked to
rollkit/go-execution
as its parent repository - The specific commit (
d1712b8c4d58
) referenced in thereplace
directive is a simple dependency bump from dependabot - There are no visible substantial changes or custom modifications in the fork
The replace
directive appears unnecessary as it points to a fork that:
- Contains the same code as the original repository
- Has no custom modifications
- Points to a commit that's just a routine dependency update
Please:
- Remove the
replace
directive and use the originalrollkit/go-execution
repository directly - If specific version pinning is needed, use a proper version tag or commit hash from the original repository
🔗 Analysis chain
Verify the use of a forked dependency.
Using a fork of go-execution
could lead to maintenance challenges and potential security risks. Please ensure:
- The fork is necessary and temporary
- There's a plan to migrate back to the official repository
- The changes in the fork are reviewed for security implications

:
Fix potential integer overflow in uint64 to int64 conversions
Converting uint64
to int64
can cause overflow if the value exceeds MaxInt64
. This affects both derivePrevRandao
and SetFinal
methods.
func (c *EngineAPIExecutionClient) derivePrevRandao(blockHeight uint64) common.Hash {
- return common.BigToHash(big.NewInt(int64(blockHeight)))
+ return common.BigToHash(new(big.Int).SetUint64(blockHeight))
}
Also update the conversion in SetFinal
:
- block, err := c.ethClient.BlockByNumber(ctx, big.NewInt(int64(height)))
+ block, err := c.ethClient.BlockByNumber(ctx, new(big.Int).SetUint64(height))
Likely invalid or redundant comment.

Security concern: Using a forked dependency
Using a fork of go-execution
instead of the official repository introduces security risks:
- The fork may not receive security updates as promptly as the official repository
- Changes in the fork may not undergo the same level of security review
- Supply chain attacks could be introduced through the fork
Consider removing the replace directive and using the official repository directly, as suggested in the previous review.

The package name and import are appropriate for an EVM execution client implementation.
36-41
: LGTM!
The ForkchoiceState struct correctly implements all required fields with appropriate types.
43-49
: LGTM!
The PayloadAttributes struct correctly implements all required fields according to the Engine API specification.
15-22
: Verify struct against Engine API specification.
The struct implementation looks correct. However, let's verify it matches the official Engine API specification.
✅ Verification successful
ForkchoiceUpdatedResponse struct matches Engine API implementation
The struct implementation is verified to be correct based on its usage throughout the codebase:
- The struct is used consistently in
engine_forkchoiceUpdatedV3
API calls - The response structure matches the expected format with:
payloadStatus
containingstatus
and optionalvalidationError
- Optional
payloadId
field
- The implementation is validated through multiple test cases and actual usage in the execution client

Review prevRandao implementation for production use.
- The current implementation has potential integer overflow issues
- Using block height directly as prevRandao might be too predictable for production use
For the immediate fix:
func (c *EngineAPIExecutionClient) derivePrevRandao(blockHeight uint64) common.Hash {
- return common.BigToHash(big.NewInt(int64(blockHeight)))
+ return common.BigToHash(new(big.Int).SetUint64(blockHeight))
}
Consider implementing a more secure randomness source for production use. Would you like assistance in implementing a more robust solution?

Fix potential integer overflow in block height conversion.
Converting uint64
to int64
in BlockByNumber
can cause overflow for large block heights.
- block, err := c.ethClient.BlockByNumber(ctx, big.NewInt(int64(height)))
+ block, err := c.ethClient.BlockByNumber(ctx, new(big.Int).SetUint64(height))

: 🛠️ Refactor suggestion
Replace global state with instance variable.
Using a global variable for lastForkchoiceUpdate
could cause interference between concurrent tests. Consider making it an instance variable of MockEngineAPI
.
-var lastForkchoiceUpdate *ForkchoiceState
type MockEngineAPI struct {
*httptest.Server
+ lastForkchoiceUpdate *ForkchoiceState
}

339-342
:
Review prevRandao implementation for production use.
- Using block height directly as prevRandao might be too predictable
- Integer overflow issue in the conversion
For immediate fix:
func (c *EngineAPIExecutionClient) derivePrevRandao(blockHeight uint64) common.Hash {
- return common.BigToHash(big.NewInt(int64(blockHeight)))
+ return common.BigToHash(new(big.Int).SetUint64(blockHeight))
}
Consider implementing a more secure randomness source for production use, such as VRF (Verifiable Random Function) or other cryptographic methods.

💡 Codebase verification
Debug settings should be removed for production deployment
Based on the documentation and docker-compose configuration, this setup appears to be intended for development and testing purposes:
- The README explicitly shows this docker-compose setup under the "Development" section
- The configuration contains multiple development-focused settings:
- Discovery disabled (
--disable-discovery
) - Hardcoded debug tip
- Maximum verbosity (
-vvvvv
)
- Discovery disabled (
- The architecture documentation confirms the presence of a test environment
These debug settings should not be used in production as they could impact performance and security.
🔗 Analysis chain
Review debug configuration for production readiness
The current configuration includes development settings that should be reviewed:
- Discovery is disabled (
--disable-discovery
) - Debug tip is hardcoded
- Maximum verbosity is set (
-vvvvv
)
Let's verify if this is the intended configuration:
The previous search was too narrow. Let's broaden our search to understand the context better by:
- Looking for any documentation about production settings
- Checking other docker-compose files that might exist
- Looking for patterns related to production, debug, or discovery settings in config files
This will help us determine if these settings are intentionally different between environments.
Let's search for any documentation that might explain the purpose of this configuration, particularly if this is meant for development/testing purposes. This will help us determine if these debug settings are intentionally set this way.

Avoid hardcoding JWT secrets in code
Hardcoding JWT secrets can lead to security vulnerabilities if the codebase is exposed. Consider loading the JWT secret from a secure configuration file or environment variable instead.
Would you like assistance in refactoring the code to securely load the JWT secret?

Improve prevRandao implementation for production use.
The current implementation has two issues:
- Potential integer overflow when converting block height
- Using block height directly as prevRandao might be too predictable for production use
For the immediate fix:
func (c *EngineAPIExecutionClient) derivePrevRandao(blockHeight uint64) common.Hash {
- return common.BigToHash(big.NewInt(int64(blockHeight)))
+ return common.BigToHash(new(big.Int).SetUint64(blockHeight))

Replace sleep with proper container readiness check
Using a fixed sleep duration for container startup is unreliable and could lead to flaky tests. Implement a proper readiness check.
Replace the sleep with a retry mechanism:
func waitForContainer(client *ethclient.Client, timeout time.Duration) error {
ctx, cancel := context.WithTimeout(context.Background(), timeout)
defer cancel()
ticker := time.NewTicker(100 * time.Millisecond)
defer ticker.Stop()

select {
case <-ctx.Done():
return fmt.Errorf("timeout waiting for container")
case <-ticker.C:
if _, err := client.BlockNumber(ctx); err == nil {
return nil
}
}
}
}
Then use it instead of sleep:
- // a reasonable time to wait for the container to start!
- // do we want a more predictable elaborate code to wait for the container to be running?
- time.Sleep(50 * time.Millisecond)
+ rpcClient, err := ethclient.Dial(TEST_ETH_URL)
