Zksync Era合约部署超详细教程，避坑实录-Toy模板网

这篇具有很好参考价值的文章主要介绍了Zksync Era合约部署超详细教程，避坑实录。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

说明：

1.zksync era部署合约和ETH等网络不同，不能直接使用remix进行部署，官方出的解决方案是使用hardhat插件。

2.合约中的constructor需要传参进去，不能直接写入

3.官方的python sdk也是不能使用的状态。

系统环境：ubuntu 22.04

1.升级apt

sudo apt update

2.安装并激活NVM

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
source ~/.bashrc

3.安装NodeJS LTS版本

nvm install --lts

4.确认已成功安装 Node.js 和 npm

node --version
npm --version

能正常显示版本就安装成功了

5.创建文件夹并初始化环境

mkdir greeter-example
cd greeter-example
npm init -y
npm i -D typescript ts-node ethers@^5.7.2 zksync-web3@^0.14.3 hardhat @matterlabs/hardhat-zksync-solc @matterlabs/hardhat-zksync-deploy

ethers 版本当前只兼容v5.7.x

zksync-web3 版本需要对应本地版本

6.设置对应的文件

文件结构如图

Zksync Era合约部署超详细教程，避坑实录

hardhat.config.ts

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

module.exports = {
  zksolc: {
    version: "1.3.5",
    compilerSource: "binary",
    settings: {},
  },
  defaultNetwork: "zkSyncTestnet",

  networks: {
    zkSyncTestnet: {
      url: "https://zksync2-testnet.zksync.dev",
      ethNetwork: "goerli", // Can also be the RPC URL of the network (e.g. `https://goerli.infura.io/v3/<API_KEY>`)
      zksync: true,
    },
  },
  solidity: {
    version: "0.8.17",
  },
};

这是在测试网发布的例子，如果想在Era主网发布

url: "https://mainnet.era.zksync.io",
ethNetwork: "mainnet"  //或者改为你自己的infura ETH主网地址

修改这两项即可。

deploy文件夹下放部署脚本deploy.ts

import { Wallet, utils } from "zksync-web3";
import * as ethers from "ethers";
import { HardhatRuntimeEnvironment } from "hardhat/types";
import { Deployer } from "@matterlabs/hardhat-zksync-deploy";

export default async function (hre: HardhatRuntimeEnvironment) {
  console.log(`Running deploy script for the Greeter contract`);

  // 初始化钱包 填入私钥
  const wallet = new Wallet("your private key");

  // 创建deployer
  const deployer = new Deployer(hre, wallet);
  // 设置部署的合约名
  const artifact = await deployer.loadArtifact("Greeter");

  // 计算gas fee
  // 参数为合约中construct的参数
  const greeting = "Hi there!";
  const deploymentFee = await deployer.estimateDeployFee(artifact, [greeting]);

  //部署合约
  
  const parsedFee = ethers.utils.formatEther(deploymentFee.toString());
  console.log(`The deployment is estimated to cost ${parsedFee} ETH`);

  const greeterContract = await deployer.deploy(artifact, [greeting]);

  console.log("constructor args:" + greeterContract.interface.encodeDeploy([greeting]));

  const contractAddress = greeterContract.address;
  console.log(`${artifact.contractName} was deployed to ${contractAddress}`);
}

contracts文件夹下放需要部署的合约sol文件

举例：Greeter.sol

//SPDX-License-Identifier: Unlicense
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;
    }
}
