debug_traceBlockByHash

​

Parameters

• tracer - String - The type of tracer, options are: callTracer or prestateTracer.
  • callTracer - String - The callTracer keeps track of all call frames, including depth - calls, that are made during a transaction.
  • prestateTracer - String - The prestateTracer replays the transaction and tracks every part of state that occurred during the transaction.
• tracerConfig - Object (Optional) - The object to specify the configurations of the tracer.
  • onlyTopCall - Boolean - When set to true, this will only trace the primary (top-level) call and not any sub-calls. It eliminates the additional processing for each call frame.

​

Returns

• txHash - The hash of the transaction.
• result - With callTracer, the call trace of the transaction, an object with:
  • from - The address the transaction is sent from.
  • gas - The integer of the gas provided for the transaction execution.
  • gasUsed - The integer of the gas used.
  • to - The address the transaction is directed to.
  • input - The data given at the time of input.
  • output - The data returned by the call, when present.
  • value - The integer of the value sent with this transaction.
  • type - The type of call.
  • calls - A list of sub-calls, when present.
