Base API method trace_replayBlockTransactions replays transactions in a specified block individually, returning the trace data for each transaction. This method is invaluable for developers, auditors, and analysts who wish to inspect the execution path of transactions within a block, including calls to other contracts, state changes, and execution outcomes without affecting the live blockchain.
Parameters
blockHashorblockNumber— The hash or number of the block whose transactions you want to replay. This can be specified as a hexadecimal string for the block hash or a hexadecimal or decimal number for the block number.traceTypes— An array of strings specifying the types of traces to return for each transaction. Common trace types include"vmTrace","trace", and"stateDiff".
Response
result— An array containing the trace data for each transaction in the specified block. Each item in the array represents the trace of a single transaction, detailing calls to contracts, value transfers, and other relevant state changes that occurred during its execution.
Use case
The trace_replayBlockTransactions method is particularly useful for conducting detailed analyses of block transactions. Developers can use it to debug contract interactions within a specific block, auditors can use it to verify the correctness and security of transactions, and analysts might use it to study transaction patterns or detect anomalies. This method provides a granular view of transaction execution, which is essential for understanding complex interactions on the blockchain.
