arbtrace_call

Executes a new message call and returns traces created at given call.

๐Ÿ“˜

All arbtrace methods on the Arbitrum One chain should be called on blocks prior to 22207815.

Parameters

  • object (object): The transaction call object, should have this shape:
    • from: The address the transaction is sent from.
    • to (string): The address the transaction is directed to.
    • gas (integer): Integer formatted as a hex string of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
    • gasPrice (integer): Integer of the gasPrice used for each paid gas encoded as a hexadecimal.
    • value (integer): Integer of the value sent with this transaction encoded as a hexadecimal.
    • data (string): The hash of the method signature followed by encoded parameters.
  • array (array): REQUIRED. The type of trace, which can be one of the following:
    • vmTrace: To get a full trace of the virtual machine's state during the execution of the given transaction, including for any subcalls.
    • trace: To get the basic trace of the given transaction.
    • stateDiff: To get information on altered Ethereum state due to execution of the given transaction.
  • blockNumber (string): The block number or tags (latest or pending).

Returns

  • array: The block traces, which have the following fields (please note that all return types are hexadecimal representations of their data type unless otherwise stated):
    • output: The data which is returned as an output encoded in hexadecimal format.
    • stateDiff: It returns the information on altered Ethereum state due to execution of the given transaction.
    • trace: It is used to retrieve the basic trace of the given information.
    • action: The action to be performed on the receiver id.
    • from: The address of the sender.
    • callType: The type of method such as call, delegatecall.
    • gas: The gas provided by the sender, encoded as hexadecimal.
    • input: The data sent along with the transaction.
    • to: The address of the receiver.
    • value: The integer of the value sent with this transaction, encoded as hexadecimal.
    • result: The integer of the gas price used encoded as hexadecimal.
    • gasUsed: The total used gas by all transactions in this block encoded as hexadecimal.
    • output: The value returned by the contract call, and it only contains the actual value sent by the RETURN method. If the RETURN method was not executed, the output is empty bytes.
    • subtraces: The traces of contract calls made by the transaction.
    • traceAddress: The list of addresses where the call was executed, the address of the parents, and the order of the current sub call.
    • type: The value of the method such as call or create.
    • vmTrace: The virtual machine traces.
    • destroyedContracts: It tracks terminated contracts in a system.
