  • 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.
