debug_traceTransaction

post https://ethereum-mainnet-archive.allthatnode.com/{apiKey}

The traceTransaction debugging method will attempt to run the transaction in the exact same manner as it was executed on the network. It will replay any transaction that may have been executed prior to this one before it will finally attempt to execute the transaction that corresponds to the given hash. OBS In most scenarios, debug.standardTraceBlockToFile is better suited for tracing!

Parameters

transactionHash - the transaction hash of the transaction that needs to be traced.
object- (Optional) The tracer object with the following fields:
- disableStorage: boolean - Setting this to true will disable storage capture (default = false).
- disableStack: boolean - Setting this to true will disable stack capture (default = false).
- enableMemory: boolean - Setting this to true will disable memory capture (default = false).
- enableReturnData: boolean - Setting this to true will disable stack capture (default = false).
- tracer: string - The type of tracer. It could be callTracer or prestateTracer
  - callTracer - The calltracer keeps track of all call frames, including depth 0 calls, that are made during a transaction
  - prestateTracer - The prestateTracer replays the transaction and tracks every part of state that occured during the transaction
- tracerConfig: object - 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
