deployContract
Deploys a contract to the network, given bytecode & constructor arguments.
Install
ts
import { deployContract } from 'viem'
Usage
ts
import { deployContract } from 'viem'
import { wagmiAbi } from './abi'
import { walletClient } from './client'
await deployContract(walletClient, {
abi,
bytecode: '608060405260405161083e38038061083e833981016040819052610...',
})
ts
export const wagmiAbi = [
...
{
inputs: [],
stateMutability: "nonpayable",
type: "constructor",
},
...
] as const;
ts
import { createWalletClient, custom } from 'viem'
import { mainnet } from 'viem/chains'
export const walletClient = createWalletClient({
chain: mainnet,
transport: custom(window.ethereum)
})
Deploying with Constructor Args
ts
import { deployContract } from 'viem'
import { wagmiAbi } from './abi'
import { walletClient } from './client'
await deployContract(walletClient, {
abi,
args: [69420],
bytecode: '608060405260405161083e38038061083e833981016040819052610...',
})
ts
export const wagmiAbi = [
...
{
inputs: [{ internalType: "uint32", name: "x", type: "uint32" }],
stateMutability: "nonpayable",
type: "constructor",
},
...
] as const;
ts
import { createWalletClient, custom } from 'viem'
import { mainnet } from 'viem/chains'
export const walletClient = createWalletClient({
chain: mainnet,
transport: custom(window.ethereum)
})
Deploying with CREATE2
Unlike normal contract deployments (a la CREATE), the CREATE2 EVM opcode is a feature that allows for the creation of smart contracts with a predetermined address.
You can derive a predetermined address using getContractAddress, and deploy it with the snippet below.
ts
import { deployContract } from 'viem'
import { wagmiAbi } from './abi'
import { walletClient } from './client'
const address = getContractAddress({
bytecode: '608060405260405161083e38038061083e833981016040819052610...',
from: '0xc961145a54C96E3aE9bAA048c4F4D6b04C13916b',
opcode: 'CREATE2',
salt: 'hello',
})
await deployContract(walletClient, {
abi,
bytecode: '608060405260405161083e38038061083e833981016040819052610...',
salt: 'hello',
})
ts
export const wagmiAbi = [
...
{
inputs: [],
stateMutability: "nonpayable",
type: "constructor",
},
...
] as const;
ts
import { createWalletClient, custom } from 'viem'
import { mainnet } from 'viem/chains'
export const walletClient = createWalletClient({
chain: mainnet,
transport: custom(window.ethereum)
})
Parameters
