tronweb.contract().new

Deploy a smart contract.

Usage

let abi = 'some abi for contract';
let code = 'bytecode';
async function deploy_contract(){
  let contract_instance = await tronWeb.contract().new({
    abi:JSON.parse(abi),
    bytecode:code,
    feeLimit:1000000000,
    callValue:0,
    userFeePercentage:1,
    originEnergyLimit:10000000,
    parameters:[param1, param2, param3,...]
  });
  console.log(contract_instance.address);
}

Parameters

Parameter	Description	Data Type	Option
abi	Smart Contract's String Application Binary Interface.	Required
bytecode	The compiled contract's identifier, used to interact with the Virtual Machine.	String	Required
feeLimit	The maximum SUN consumes by deploying this contract. (1TRX = 1,000,000SUN)	Integer, long	Optional
allValue	Amount of SUN transferred to the contract with this transaction.(1TRX = 1,000,000SUN)	Integer	Optional
userFeePercentage	The energy consumption percentage specified for the user calling this contract.	Integer between 0 and 100	Optional
originEnergyLimit	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.	Integer	Optional
parameters	Parameter passed to the constructor of the contract.	Array	Optional, required if constructor needs parameters

Important Note: for the userFeePercentage parameter, it is strongly recommended to set the integer value between 1 and 99 (inclusive). Setting as 0 could potentially open the contract developer up to an infinite loop time-out attack.
