eth_getTraceActionByTxHash
This method returns logs of internal transactions by the hash of a transaction.
Parameters
DATA, 32 Bytes: Hash of a transaction.Object: Filter options:fromUser:DATA|Array, 20 Bytes (optional) - Address of the sender.toBlock:DATA|Array, 20 Bytes (optional) - Address of the receiver.opCode: String (optional) - An EVM opcode for a transaction’s log.minValue:QUANTITY|TAG(optional) - The minimal value or amount transferred in BRC.
Returns
An object containing an internal transaction’s log, or null if no log was found:
transactionHash:DATA, 32 Bytes - Hash of the transaction.blockHash:DATA, 32 Bytes - Hash of the block (null if pending).blockNumber:QUANTITY- Block number of the transaction.logs: Array of log objects generated by the transaction:from:DATA, 20 Bytes - Address of the sender.to:DATA, 20 Bytes - Address of the receiver (null if it’s a contract creation transaction).value:QUANTITY- Value transferred in BRC.success: Boolean - Indicates whether the call was successful.opcode:DATA- The EVM opcode of the transaction’s log.depth:QUANTITY- The depth of the call stack in EVM.gas:QUANTITY- Gas provided by the sender.gas_used:QUANTITY- Amount of gas used by the transaction.input:DATA- Data sent along with the transaction.trace_address:QUANTITY|Array- Array representing the call trace depth during execution.
