在zkSync Era上部署合约大致分为4歩：

**1 安装环境**

电脑上安装好nodejs，node版本不低于16.13.0, 安装包管理npm和yarn

**2 初始化项目**

创建项目主目录，在主目录下运行：

yarn init -y

和

yarn add -D typescript ts-node @types/node ethers@^5.7.2 zksync-web3 @ethersproject/hash @ethersproject/web hardhat @matterlabs/hardhat-zksync-solc @matterlabs/hardhat-zksync-deploy

新建hardhat.config.ts文件，内容如下：

import "@matterlabs/hardhat-zksync-deploy"; import "@matterlabs/hardhat-zksync-solc";

module.exports = { zksolc: { version: "1.3.5", compilerSource: "binary", settings: {}, }, defaultNetwork: "zkMainnet", networks: { zkMainnet: { url: "[https://mainnet.era.zksync.io](https://mainnet.era.zksync.io)", ethNetwork: "mainnet", zksync: true, }, }, solidity: { version: "0.8.17", }, };

**3 创建并编译合约**

在主目录下创建contracts子目录，新建极简合约contracts/Greater.sol:

//SPDX-License-Identifier: Unlicensed pragma solidity ^0.8.0;

contract Greeter { string private greeting;

    constructor(string memory \_greeting) {
        greeting = \_greeting;
    }
    
    function greet() public view returns (string memory) {
        return greeting;
    }
    
    function setGreeting(string memory \_greeting) public {
        greeting = \_greeting;
    }
    

}

使用 yarn hardhat compile 命令编译合约。

**4 部署合约**

在主目录下创建deploy子目录，新建deploy/deploy.js文件：

    import { utils, Wallet } from "zksync-web3";
    import * as ethers from "ethers";
    import { HardhatRuntimeEnvironment } from "hardhat/types";
    import { Deployer } from "@matterlabs/hardhat-zksync-deploy";
    
    // An example of a deploy script that will deploy and call a simple contract.
    export default async function (hre: HardhatRuntimeEnvironment) {
      console.log(`Running deploy script for the Greeter contract`);
    
      let key = '<YOUR_PRIVATE_KEY>'
      // Initialize the wallet.
      const wallet = new Wallet(key);
      console.log(wallet.address)
      
      // Create deployer object and load the artifact of the contract we want to deploy.
      const deployer = new Deployer(hre, wallet);
      const artifact = await deployer.loadArtifact("Greeter");
    
      // Deploy this contract. The returned object will be of a `Contract` type, similarly to ones in `ethers`.
      // `greeting` is an argument for contract constructor.
      const greeting = "Hi Frens!";
      const greeterContract = await deployer.deploy(artifact, [greeting]);
    
      // Show the contract info.
      const contractAddress = greeterContract.address;
      console.log(`${artifact.contractName} was deployed to ${contractAddress}`);
    
      // Call the deployed contract.
      const greetingFromContract = await greeterContract.greet();
      if (greetingFromContract == greeting) {
        console.log(`Contract greets us with ${greeting}!`);
      } else {
        console.error(`Contract said something unexpected: ${greetingFromContract}`);
      }
    }
    
    注： <YOUR_PRIVATE_KEY>替换成你的钱包私钥
    
    
    用命令 yarn hardhat deploy-zksync 部署合约。
