85-89: Consider aggregating errors for caller awarenessWhile errors are correctly logged for individual transactions, the function always returns nil regardless of how many transactions failed. Consider adding an error return that indicates if the stress test encountered a significant number of failures.
func StressIdentityUpdates( ctx context.Context, logger *zap.Logger, n int, contractAddress, rpc, privateKey string, -) error { +) (int, error) { // ... existing code ... logger.Info("Stress Test Summary", zap.Int("total_transactions", n), zap.Int("successful_transactions", successCount), zap.Duration("total_duration", totalDuration), zap.Duration("average_duration", avgDuration), ) - return nil + // Return the number of failed transactions so caller can determine success + failedCount := n - successCount + if failedCount > 0 { + return failedCount, fmt.Errorf("%d of %d transactions failed", failedCount, n) + } + return 0, nil }

24-31: Great addition of EncodeDuration configuration!Adding the
EncodeDuration: zapcore.StringDurationEncoderfield to the encoder config ensures that durations will be formatted as human-readable strings in the logs. This complements the duration logging added in the stress testing code and improves readability of performance metrics.pkg/stress/cast.go (1)
18-18: Good type change for nonce fieldChanging the
Noncefield type from*intto*uint64is a good practice since:
- Ethereum nonces are non-negative values that can grow large
- This matches the type used in the updated stress testing logic
- It provides better type safety by preventing negative values
This change aligns well with the concurrent nonce handling implemented in the stress code.

32-40: Well-structured result tracking implementationThe
Resultstruct is a good design choice for tracking metrics. It captures all relevant transaction data (index, nonce, success status, and duration) which enables the detailed analytics reporting added at the end of the function.
41-41: Effective concurrency management with semaphoreUsing a semaphore channel with 50 slots is an excellent approach to limit concurrent transactions. This prevents overwhelming the node with too many simultaneous requests while still achieving high throughput.
48-50: Thread-safe nonce managementUsing an atomic counter for nonce management is the correct approach for concurrent execution. This ensures each transaction gets a unique, sequential nonce without race conditions.
51-91: Solid implementation of concurrent transaction executionThe implementation correctly:
- Launches each transaction in its own goroutine
- Uses the semaphore pattern to limit concurrency
- Safely increments the nonce counter with atomic operations
- Protects shared state (results slice) with a mutex
- Includes proper timing and logging
This is a significant improvement over sequential execution for stress testing.
95-111: Excellent analytics reportingThe aggregation and reporting of test metrics is thorough and well-structured. Calculating and logging total transactions, success rate, total duration, and average duration provides valuable insights into the stress test performance.
116-116: Good type consistency improvementChanging the return type of
getCurrentNoncefrominttouint64improves type consistency and safety throughout the codebase. This aligns properly with Ethereum's use of nonces as unsigned integers.
