When it comes to deploying, there are no official plugins that implement a deployment system for Hardhat yet, but there's an open issue (opens new window) with some ideas and we'd value your opinion on how to best design it.
In the meantime, we recommend deploying your smart contracts using scripts, or using the hardhat-deploy community plugin (opens new window). You can deploy the Greeter
contract from the sample project with a deploy script scripts/deploy.js
like this:
async function main() {
// We get the contract to deploy
const Greeter = await ethers.getContractFactory("Greeter");
const greeter = await Greeter.deploy("Hello, Hardhat!");
await greeter.deployed();
console.log("Greeter deployed to:", greeter.address);
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error);
process.exit(1);
});
You can deploy in the localhost
network following these steps:
Start a local node
npx hardhat node
Open a new terminal and deploy the smart contract in the localhost
network
npx hardhat run --network localhost scripts/deploy.js
As general rule, you can target any network configured in the hardhat.config.js
npx hardhat run --network <your-network> scripts/deploy.js
You can use Hardhat alongside Truffle if you want to use its migration system. Your contracts written using Hardhat will just work with Truffle.
All you need to do is install Truffle and follow their migrations guide (opens new window).
