debug_traceBlockByHash

Returns EVM execution traces for all transactions in a block by block hash.

Replays all transactions in a block identified by its hash and returns an execution trace for each.

Debug methods replay all transactions in the block and are computationally expensive. Availability varies by node provider.

Parameters

blockHash · string · required

The 32-byte block hash.

traceOptions · object

Optional trace configuration. Accepts the same fields as debug_traceTransaction.

Returns

result · array

An array of trace result objects, one per transaction in the block.
