Modules: trace

trace_block

Block returns the structured logs created during the execution of EVM and returns them as a JSON object. The correct name will be TraceBlockByNumber, though we want to be compatible with Parity trace module.

trace_call

Call lets you trace a given eth_call. It collects the structured logs created during the execution of EVM if the given transaction was added on top of the provided block and returns them as a JSON object. You can provide -2 as a block number to trace on top of the pending block.
