Returns the number of possible tracing results by executing an eth call within the context of the given block execution.

This method will use 40 Compute Units.

Parameters

object - Object - The transaction call object with the following fields:

• from - String - The address the transaction is sent from

• to - String - Required - The address the transaction is directed to

• gas - Integer - The integer of the gas provided for the transaction execution

• gasPrice - Integer - The integer of the gasPrice used for paid gas

• value - Integer - The integer of the value sent with this transaction

• data - String - The has of the method signature and encoded parameters

blockReference - String - Required - The block number in hexadecimal format, the block hash, or tags: "earliest", "latest" or "pending".

object - Object (Optional) - The tracer object with the following fields:

• 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 trackers 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

result - An object with the result of the trace, containing:

• gas - The integer of the total consumed gas in the transaction.

• failed - A boolean to indicate whether the transaction was successful or not.

• returnValue - The return value of the executed contract call.

• structLogs - An array of the trace result of each step with the following fields:

  • pc - The current index in bytecode.

  • op - The name of the current executing operation.

  • gas - The available gas in the execution.

  • gasCost - The gas cost of the operation.

  • depth - The number of levels of calling functions.

  • error - The error of the execution.

  • stack - An array of values in the current stack.

  • memory - An array of values in the current memory.

  • storage - The mapping of the current storage.

  • refund - Total total value of the current refund value.
