raw_dataobject
The unsigned transaction body containing the contract instruction and blockchain reference data.
object
contractarray_of_objects
The list of contract instructions to be executed by this transaction.
object
parameterobject
The typed payload describing the specific contract call being made.
object
valueobject
The decoded fields of the contract — here, a request to register the account as a new Super Representative candidate.
object
owner_addressstring
[Required] The address of the account applying to become a witness (SR candidate), in hex format.
urlstring
