Transaction initiator address. (Format: Base58 or Hex)

Contract address. (Format: Base58 or Hex)

Function selector, e.g., transfer(address,uint256).

ABI-encoded function parameters (Hex String).

This field transmits the necessary data for smart contract interaction, including the function being called and its parameters. You may choose to use the data field, which contains the complete ABI-encoded information, or use the function_selector and parameter fields separately. Note that if both data and function_selector are present, the system will prioritize using the function_selector and parameter fields for the contract interaction.
