1、打开gitpod

2、nvm install 16

3、新建文件夹

mkdir ex
cd ex

4、安装依赖

yarn init -y

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

yarn add -D @matterlabs/hardhat-zksync-verify @nomicfoundation/hardhat-verify

5、新建配置文件，命名为"hardhat.config.ts"。

6、填进去

默认测试网

import "@matterlabs/hardhat-zksync-deploy";
import "@matterlabs/hardhat-zksync-solc";
import "@matterlabs/hardhat-zksync-verify";
module.exports = {
  zksolc: {
    version: "1.3.13",
    compilerSource: "binary",
    settings: {},
  },
  defaultNetwork: "zkSyncTestnet",

  networks: {
    zkSyncTestnet: {
      url: "https://zksync2-testnet.zksync.dev",
      ethNetwork: "goerli",
      zksync: true,
    }, 
  },
  solidity: {
    version: "0.8.17",
  },
};

默认主网

import "@matterlabs/hardhat-zksync-deploy";
import "@matterlabs/hardhat-zksync-solc";
import "@matterlabs/hardhat-zksync-verify";
module.exports = {
  zksolc: {
    version: "1.3.13",
    compilerSource: "binary",
    settings: {},
  },
  defaultNetwork: "zkMainnet",

  networks: {
    zkSyncTestnet: {

      ethNetwork: "goerli",
      zksync: true,
    },
    zkMainnet: {
      url: "https://zksync2-mainnet.zksync.io",
      ethNetwork: "mainnet",
      zksync: true,
    }
  },
  solidity: {
    version: "0.8.17",
  },
};

7、建两个文件夹 一个叫contracts，一个叫deploy

mkdir contracts deploy

8、在contracts文件夹下建立EHS.sol文件，代码如下（如果是部署erc20合约就贴你自己的erc20合约）：

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.17;

contract EHS {
}

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.17;

contract WXY {
    string public name = "WXY";
    string public symbol = "WXY";
    uint8 public decimals = 18;
    uint256 public totalSupply = 0;
    uint256 public maxSupply = 100000000 * 10**uint256(decimals);
    uint256 public mintedTokens = 0;
    bool public mintingFinished = false;

    mapping(address => uint256) public balanceOf;

    event Transfer(address indexed from, address indexed to, uint256 value);
    event Mint(address indexed to, uint256 value);
    event MintFinished();

    modifier canMint() {
        require(!mintingFinished, "Minting has already finished");
        _;
    }

    constructor() {
        balanceOf[msg.sender] = totalSupply;
    }

    function transfer(address to, uint256 value) external returns (bool) {
        require(value >= 1 * 10**uint256(decimals), "Invalid transfer amount");

        balanceOf[msg.sender] -= value;
        balanceOf[to] += value;

        emit Transfer(msg.sender, to, value);
        return true;
    }

    function mint() external canMint() {
        require(totalSupply + 1 <= maxSupply, "Exceeds maximum supply");

        balanceOf[msg.sender] += 1;
        totalSupply += 1;
        mintedTokens += 1;
        mintingFinished = true;

        emit Mint(msg.sender, 1);
        emit MintFinished();
    }
}

9、编译合约

yarn hardhat compile

10、安装dotenv库

npm install dotenv

12、新建.env文件填入

WALLET_PRIVATE_KEY=your_private_key_here
NODE_ENV=test

12、在deploy文件夹下创建deploy.ts文件

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

// load env file
import dotenv from "dotenv";
dotenv.config();

// load wallet private key from env file
const PRIVATE_KEY = process.env.WALLET_PRIVATE_KEY || "";

if (!PRIVATE_KEY) throw "⛔️ Private key not detected! Add it to the .env file!";

// 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 WXY contract`);

  // Initialize the wallet.
  const wallet = new Wallet(PRIVATE_KEY);

  // Create deployer object and load the artifact of the contract you want to deploy.
  const deployer = new Deployer(hre, wallet);
  const artifact = await deployer.loadArtifact("WXY");

  // Estimate contract deployment fee
  const deploymentFee = await deployer.estimateDeployFee(artifact, [ ]);

  // ⚠️ OPTIONAL: You can skip this block if your account already has funds in L2
  // Deposit funds to L2
  // const depositHandle = await deployer.zkWallet.deposit({
  //   to: deployer.zkWallet.address,
  //   token: utils.ETH_ADDRESS,
  //   amount: deploymentFee.mul(2),
  // });
  // // Wait until the deposit is processed on zkSync
  // await depositHandle.wait();

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

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

  //obtain the Constructor Arguments
  console.log("Constructor args:" + deployedContract.interface.encodeDeploy([]));

  // Show the contract info.
  const contractAddress = deployedContract.address;
  console.log(`${artifact.contractName} was deployed to ${contractAddress}`);

  // verify contract for tesnet & mainnet
  if (process.env.NODE_ENV != "test") {
    // Contract MUST be fully qualified name (e.g. path/sourceName:contractName)
    const contractFullyQualifedName = "contracts/WXY.sol:WXY";

    // Verify contract programmatically
    const verificationId = await hre.run("verify:verify", {
      address: contractAddress,
      contract: contractFullyQualifedName,
      bytecode: artifact.bytecode,
    });
  } else {
    console.log(`Contract not verified, deployed locally.`);
  }
}

13、部署合约

yarn hardhat deploy-zksync

14、合约验证

借助 Remix 展开合约，获取单一文件格式的代码，右键选择 Flatten，然后填入代码行进行验证

15、构建前端dapp

1、打开gitpod

2、nvm install 16

3、新建文件夹

mkdir ex
cd ex

4、安装依赖

yarn init -y

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

yarn add -D @matterlabs/hardhat-zksync-verify @nomicfoundation/hardhat-verify
