To deploy a smart contract on zkSync, you can use the Hardhat framework along with specific plugins designed for zkSync. Here's a step-by-step guide to help you deploy your contract using Hardhat:

Prerequisites

• Ensure you have Node.js (version 14.x or later) installed.
• You should have Yarn or npm as your package manager.
• Initialize a Hardhat project if you haven't already.

Steps to Deploy a Contract on zkSync

1. Install the necessary plugins:

   • Install the hardhat-zksync-deploy plugin which is specifically designed for deploying contracts on zkSync. You can install it using the following command:

     yarn add @matterlabs/hardhat-zksync-deploy

   • Once installed, add the plugin at the top of your hardhat.config.ts file.

2. Configure your Hardhat project:

   • Ensure your hardhat.config.ts file is set up to include zkSync as a network. This typically involves specifying the network details and ensuring your wallet is configured with sufficient testnet ETH. You can obtain Sepolia ETH from network faucets and bridge these funds to zkSync using bridges.

3. Write your deployment script:

   • Navigate to the root directory of your project.
   • Create a new folder named deploy if it doesn't already exist.
   • Inside the deploy folder, create a new file for your deployment script (e.g., deploy-my-contract.ts).
   • Write the deployment script using Hardhat's environment. An example script might look like this:

     async function main() {
       const ContractFactory = await ethers.getContractFactory("MyContract");
       const contract = await ContractFactory.deploy();
       console.log("Contract deployed to:", contract.address);
     }
     
     main().catch((error) => {
       console.error(error);
       process.exit(1);
     });

4. Deploy the contract:

   • Run your deployment script by executing the following command in your terminal:

     npx hardhat run scripts/deploy-my-contract.ts --network zksync

5. Verify the deployment:

   • After deployment, you can verify your contract on the zkSync block explorer by searching for the deployed contract address.

This guide should help you deploy your smart contract on zkSync using Hardhat. If you encounter any specific errors during the process, please provide the error messages for more detailed assistance.
