​

Parameters

• object — the transaction call object:
  • from — (optional) the string of the address used to send the transaction.
  • to — the string of the address to which the transaction is directed, a wallet, or a smart contract.
  • gas — (optional) the maximum amount of gas that can be used by the transaction.
  • gasprice — (optional) the amount of gas price the sender is willing to pay for each gas unit in wei.
  • value — (optional) the value sent with this transaction, encoded as hexadecimal.
  • data — (optional) additional data to be sent with the call, usually used to invoke functions from smart contracts as a string of the hash of the method signature and encoded parameters; see the Ethereum Contract ABI.
• quantity — the integer of a block, encoded as hexadecimal.
• array — an array identifying the type of tracer and its configuration:
  • trace — tracer that captures information on all call frames executed during a transaction. The resulting nested list of call frames is organized into a tree structure that reflects the way the Ethereum Virtual Machine works and can be used for debugging and analysis purposes.

​

Response

• output — the data returned as a result of the transaction, encoded in hexadecimal format.
• stateDiff — reveals changes to the state resulting from the execution of the given transaction.
• trace — the basic trace of specific information.
  • action — the operation to be performed on the recipient.
    • from — the address initiating the transaction.
    • callType — the type of method, such as call or delegatecall.
    • gas — the units of gas supplied by the sender, encoded in hexadecimal format.
    • input — the data transmitted along with the transaction, typically used for interaction with smart contracts.
    • to — the recipient’s address. If it’s a contract creation transaction, this field is null.
    • value — the amount sent with the transaction, encoded as a hexadecimal.
  • result — the value of the gas price used, encoded as hexadecimal.
    • gasUsed — the total amount of gas used by all the transactions in the block, encoded as hexadecimal.
    • output — the return value from the contract call, encoded in hexadecimal. If the RETURN method isn’t executed, the output will be empty bytes.
  • subtraces — a list of contract calls made by the transaction, each represented as a nested callframe object.
  • traceAddress — a list of addresses where the call was executed, the addresses of the parent calls, and the order of the current sub-call.
  • type — the value of the method, such as call or create.
• vmTrace — a comprehensive trace of the virtual machine’s state during the execution of a given transaction, including any sub-calls.
