trace_replayBlockTransactions | Taiko RPC Docs

Replay all transactions in a block and return traces on Taiko. Requires archive node for Taiko mainnet.

Replays all transactions in a block on Taiko 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 Taiko
Comprehensive block-level execution analysis - Audit exactly how each transaction in a block modified state for Taiko mainnet
Audit entire block execution - Verify that all transactions in a block executed as expected
Historical block replay - Re-execute blocks at any point in Taiko chain history

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
