#Deploying your contracts

When it comes to deploying, there are no official plugins that implement a deployment system for Hardhat yet. We are working on it.

In the meantime, we recommend deploying your smart contracts using scripts, or using the hardhat-deploy community plugin. You can deploy the Lock contract from the sample project with a deployment script like this:

TypeScript

JavaScript

import { ethers } from "hardhat";

async function main() {
  const currentTimestampInSeconds = Math.round(Date.now() / 1000);
  const unlockTime = currentTimestampInSeconds + 60;

  const lockedAmount = ethers.utils.parseEther("0.001");

  const Lock = await ethers.getContractFactory("Lock");
  const lock = await Lock.deploy(unlockTime, { value: lockedAmount });

  await lock.deployed();

  console.log(
    `Lock with ${ethers.utils.formatEther(lockedAmount)}ETH and unlock timestamp ${unlockTime} deployed to ${lock.address}`
  );
}

// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

// We require the Hardhat Runtime Environment explicitly here. This is optional
// but useful for running the script in a standalone fashion through `node <script>`.
//
// You can also run a script with `npx hardhat run <script>`. If you do that, Hardhat
// will compile your contracts, add the Hardhat Runtime Environment's members to the
// global scope, and execute the script.
const hre = require("hardhat");

async function main() {
  const currentTimestampInSeconds = Math.round(Date.now() / 1000);
  const unlockTime = currentTimestampInSeconds + 60;

  const lockedAmount = hre.ethers.utils.parseEther("0.001");

  const Lock = await hre.ethers.getContractFactory("Lock");
  const lock = await Lock.deploy(unlockTime, { value: lockedAmount });

  await lock.deployed();

  console.log(
    `Lock with ${ethers.utils.formatEther(
      lockedAmount
    )}ETH and unlock timestamp ${unlockTime} deployed to ${lock.address}`
  );
}

// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main().catch((error) => {
  console.error(error);
  process.exitCode = 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

TypeScript

JavaScript

npx hardhat run --network localhost scripts/deploy.ts

npx hardhat run --network localhost scripts/deploy.js

As general rule, you can target any network from your Hardhat config using:

npx hardhat run --network <your-network> scripts/deploy.js
