trace_rawTransaction

Traces a signed transaction that has not yet been included in a block, without broadcasting it.

This method will use 80 Compute Units.

The transaction must be signed by an account whose nonce has not yet been used. Passing an already-mined transaction returns nonce too low.

---

Parameters

data - String - Required - The signed transaction data, as a hexadecimal string

array - Array - Required - The type of trace, which can be one of the following:

• trace - string - To get the basic trace of the given transaction

• stateDiff - string - To get information on altered Ethereum state due to execution of the given transaction

• vmTrace - string - To get a full trace of the virtual machine's state during the execution of the given transaction, including for any subcalls

Returns

object - object - The transaction trace result object

• output - string - The data returned as output encoded in hexadecimal format

• stateDiff - object - The altered Ethereum state due to execution of the given transaction, or null if not requested

• trace - array - An array of basic trace objects for the given transaction containing:

  • action - object - The ParityTrace action object containing call details

    • from - string - The address of the sender

    • callType - string - The type of method such as call, staticcall, delegatecall

    • gas - string - The gas provided by the sender, encoded as hexadecimal

    • input - string - The input data sent along with the transaction

    • to - string - The address of the receiver

    • value - string - The integer of the value sent with this transaction, encoded as hexadecimal

  • result - object - The execution result of the trace

    • gasUsed - string - The amount of gas used by this trace

    • output - string - The return value of the contract call, empty if no RETURN executed

  • subtraces - integer - The number of subtraces (internal calls) within this trace

  • traceAddress - array - The list of addresses where the call executed, including parent calls and order

  • type - string - The type of the trace, such as call or create

• vmTrace - object - The full trace of the virtual machine's state during execution, or null if not requested
