  • contract_address - Smart contract address. If visible=true, use base58check format, otherwise use hex format.

  • function_selector - Function call, must not be left blank.

  • parameter - Parameter encoding needs to be in accordance with the ABI rules, the rules are more complicated, users can use the ethers library to encode,For details, please refer to the document-Guide-Smart Contract-Best Practice-Parameter Encoding and Decoding.
