    • 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
