trace_replayBlockTransactions - MegaETH RPC Method

Replay all transactions in a block and return traces on MegaETH. Requires archive node for high-frequency trading, real-time gaming, instant payments, and latency-sensitive applications.

Replays all transactions in a block on MegaETH and returns the requested traces.

Archive Node Required

This method requires an archive node. It is not available on full nodes.

When to Use This Method

  • Replay all transactions in a block - Get vmTrace, stateDiff, and trace for every transaction in a block on MegaETH
  • Comprehensive block-level execution analysis - Audit exactly how each transaction in a block modified state for high-frequency trading, real-time gaming, instant payments, and latency-sensitive applications
  • Audit entire block execution - Verify that all transactions in a block executed as expected
  • Historical block replay - Re-execute blocks at any point in MegaETH chain history

Best Practices

  • Very resource-intensive; each transaction is fully traced with all requested types
  • Limit to small blocks or use specific tracer types to reduce response size
  • Request only the trace types you actually need to minimize overhead
  • Requires archive node access; not available on standard full nodes
