Deploys a contract. Returns TransactionExtention, which contains an unsigned transaction.

Body params:

  • abi - Smart Contract's Application Binary Interface

  • bytecode - The compiled contract's identifier, used to interact with the Virtual Machine.

  • fee_limit - Maximum TRX consumption, measured in SUN (1 TRX = 1,000,000 SUN).

  • parameter - Parameter passed to the constructor of the contract. Call the virtual machine format of the parameter [1, 2], use the js tool provided by remix, convert the parameter array [1, 2] called by the contract caller into the parameter format required by the virtual machine.

  • origin_energy_limit - The max energy which will be consumed by the owner in the process of execution or creation of the contract, is an integer which should be greater than 0.

  • owner_address - Contract owner address, converted to a hex string

  • name - Contract name

  • call_value - Amount of TRX transferred with this transaction, measured in SUN (1TRX = 1,000,000 SUN)

  • consume_user_resource_percent - The same as User Pay Ratio. The percentage of resources specified for users who use this contract. This field accepts integers between [0, 100]. If it is 0, it means the user does not consume resources until the developer resources are exhausted. However, it is strongly recommended to set the value between 1 and 99 (inclusive). This is prevent the contract developer from potential malicious infinite loop time out attacks.

  • permission_id - Optional. Whehter the address is in base58 format.

  • visible - Optional. Whehter the address is in base58 format.
