+title: '👷 Deploy to Etherlink with Hardhat'
+---
+
+[Hardhat](https://hardhat.org/) is a suite of tools for working with Ethereum contracts and dApps.
+You can use Hardhat to deploy contracts to Etherlink just like you use it on other networks:
+
+1. Set up a new Hardhat project by running `npx hardhat init`.
+1. Add Etherlink as a network by putting the Etherlink RPC node and your private key in the `hardhat.config.js` file, as in this example:
+
+   ```javascript
+   import "@nomicfoundation/hardhat-toolbox";
+   import 'dotenv/config';
+
+   const config = {
+     solidity: "0.8.19",
+     networks: {
+       etherlinkTest: {
+         url: "https://node.ghostnet.etherlink.com",
+         accounts: [process.env.MY_PRIVATE_KEY],
+       }
+     }
+   };
+
+   export default config;
+   ```
+
+1. Create a contract or use the default contract in the `contracts` folder.
+1. Compile the contract by running `npx hardhat compile`.
+1. Update the default `scripts/deploy.js` file to deploy your contract.
+For example, if your contract is named "MyContract.sol" and accepts a string value and an integer value in the constructor, the deployment script looks like this example:
+
+   ```javascript
+   import { ethers } from "hardhat";
+
+   async function deployMyContract() {
+     const deployedContract = await ethers.deployContract("MyContract", ["Hello", 5]);
+     await deployedContract.waitForDeployment();
+   }
+
+   deployMyContract().catch((error) => {
+     console.error(error);
+     process.exitCode = 1;
+   });
+   ```
+
+1. Run the deployment script on the Etherlink network with this command:
+
+   ```bash
+   npx hardhat run --network etherlinkTest scripts/deploy.js
+   ```
+
+   This command refers to the `etherlinkTest` network in the Hardhat config file.
+
+1. Copy the address of the deployed contract from the log.
+
+Now you can interact with the contract from Hardhat.
+For example, if the contract has a function named "DoSomething," you can call it with this code:
+
+   ```javascript
+   import { ethers } from "hardhat";
+
+   async function callMyContract() {
+     const MyContract = await ethers.getContractFactory("MyContract");
+     const contract = MyContract.attach(
+       // The deployed contract address
+       "0xcDd461a8dD3d519111Fe7a4ac2b9563AcEbF5B7c"
+     );
+
+     await contract.DoSomething();
+   }
+
+   callMyContract().catch((error) => {
+     console.error(error);
+     process.exitCode = 1;
+   });
+   ```
+
+Then you can run this script on the Etherlink network with the command `npx hardhat run --network etherlinkTest scripts/myScript.js`.
