Deploying a smart contract on zkSync, particularly on the testnet, involves several steps and prerequisites. Here’s a step-by-step guide to help you get started:

Prerequisites

1. Node.js: Ensure you have Node.js version 14.x or later installed on your machine.
2. Package Manager: You should have Yarn or npm installed.
3. Hardhat Project: You need an initialized Hardhat TypeScript project.
4. Wallet with Testnet ETH: Your wallet should have sufficient Sepolia ETH on Ethereum and zkSync Era Testnet to pay for deploying smart contracts. You can obtain Sepolia ETH from network faucets. Additionally, you can get testnet ETH for zkSync Era using bridges to bridge funds to zkSync.

Steps to Deploy a Smart Contract

1. Install Hardhat zkSync Plugins: You need to install the hardhat-zksync-deploy and hardhat-zksync-ethers plugins. These plugins facilitate the deployment of smart contracts on zkSync. You can install these using npm or Yarn:

   npm install hardhat-zksync-deploy hardhat-zksync-ethers
   # or
   yarn add hardhat-zksync-deploy hardhat-zksync-ethers

2. Configure Hardhat: Add the installed plugins at the top of your hardhat.config.ts file.
3. Write Your Smart Contract: Navigate to the contracts directory in your project and create your smart contract files there.
4. Deploy the Contract:
   • To deploy your contract, you can use the hardhat-zksync-deploy plugin. This plugin simplifies the deployment process on the zkSync network.
   • Run the deployment script from your Hardhat project's root directory. The specific command will depend on the script you have set up in your Hardhat configuration.

Verifying Deployment

• After deploying your contract, you can verify it on the Sepolia testnet block explorer by using the deployed address of your contract.

Additional Resources

• For a more detailed guide and examples, you can refer to the Deploying Smart Contracts tutorial on the zkSync documentation site.
• It’s also helpful to familiarize yourself with zkSync’s development tools and SDKs, which provide further functionalities for interacting with your deployed contracts.

This should give you a comprehensive start to writing and deploying smart contracts on zkSync's testnet. If you encounter specific issues during the process, feel free to provide more details for further assistance.
