Executes a call within the context of the given block and returns the trace of its execution. This method will use 80 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 call data: the 4-byte function selector followed by the ABI-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 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

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