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", 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。
