Contract & Deployment Script

Prepare your contract & deployment script

Deploying Your Smart Contract with Ignition

Paste Your Solidity Contract

Go to contracts and use the one you built in the Solidity lessons, or drop in an example like this:

pragma solidity ^0.8.20;
contract MyContract {
    uint public value;
    constructor(uint _value) {
        value = _value;
    }
}
pragma solidity ^0.8.20;
contract MyContract {
    uint public value;
    constructor(uint _value) {
        value = _value;
    }
}

Create the Deploy Script

File path: contracts/ignition/modules/myScript.ts

import { ethers } from "hardhat";
async function main() {
  const [deployer] = await ethers.getSigners();
  console.log("Deploying with:", deployer.address);
  const ContractFactory = await ethers.getContractFactory("MyContract");
  const contract = await ContractFactory.deploy(42);
  console.log("Contract deployed at:", contract.target);
}
main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});
import { ethers } from "hardhat";
async function main() {
  const [deployer] = await ethers.getSigners();
  console.log("Deploying with:", deployer.address);
  const ContractFactory = await ethers.getContractFactory("MyContract");
  const contract = await ContractFactory.deploy(42);
  console.log("Contract deployed at:", contract.target);
}
main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});
