trace_rawTransaction RPC Method

trace_rawTransaction executes a raw transaction but returns traces instead of posting it on chain.

Note: Chainnodes does not support trace_rawTransaction yet as erigon (opens in a new tab) hasn't implemented it to date. In the meantime you can easily replace this call with trace_call.

Parameters

1.RAW TRANSACTION [required]

The raw transaction as a string.

2.TRACE TYPE [required]

  • array - The type of traces to include

    • vmTrace - Include the full trace of the virtual machine during the transaction

    • trace - Include the basic trace of the transaction

    • stateDiff - Include state changes caused by the transaction

Returns

  • object - The trace object

    • output - The output (return value) of the call

    • stateDiff - The state changes that would happen due to the transaction in the given eth_call

    • vmTrace - The full trace of the virtual machine's state during execution of the given eth_call, including any sub-calls

    • trace - The trace of the call

      • action - The action to be performed

        • from - The address of the sender

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

        • gas - The gas provided by the sender

        • input - The input data of the call or delegatecall

        • to - The address of the receiver

        • value - The amount of ETH sent with this transaction

      • result - The result of the transaction

        • gasUsed - Gas used by the transaction

        • output - The return value of the call. Can be empty.

      • subtraces - The traces of internal transactions (calls made by the contract)

      • traceAddress - The list of addresses where the call was executed, the address of the parents and the order of the current sub call
