Parameters

Parameter	Type	Description
`transactionHash`	`HASH`	32-byte transaction hash to inspect as 0x-prefixed hex.

Returns

Type: ARRAY
Description: Array of trace objects recorded during transaction execution, in execution order.

Notes

trace_transaction is supported on chains with Parity/OpenEthereum-style trace modules enabled; see the availability table below. A block outside the state window returns -32011, and an unknown hash returns -32000; neither is billed. For Geth-style call trees, use debug_traceTransaction.
