Sushiswap的部署方法

Posted 2021-11-12 sanqima

    SushiSwap是从UniswapV2-core、 UniswapV2-periphery分叉而来，加了MasterChef合约、SushiToken等合约。下面介绍，使用truffle将Sushiswap部署到ganache。

1、下载Sushiswap-core

    地址：https://github.com/sushiswap/sushiswap
    下载之后，解压，将文件夹名称sushiswap-master 改成 sushiswap。

2、新建WETH.sol

    参考cn.etherscan.com里的WETH合约，在sushiswap/contracts目录下，新建一个WETH.sol文件，内容如下：
    //WETH.sol (去掉了末尾的注释)

pragma solidity 0.6.12;

contract WETH {
    string public name     = "Wrapped Ether";
    string public symbol   = "WETH";
    uint8  public decimals = 18;

    event  Approval(address indexed src, address indexed guy, uint wad);
    event  Transfer(address indexed src, address indexed dst, uint wad);
    event  Deposit(address indexed dst, uint wad);
    event  Withdrawal(address indexed src, uint wad);

    mapping (address => uint)                       public  balanceOf;
    mapping (address => mapping (address => uint))  public  allowance;

    receive() external payable {
        deposit();
    }
    function deposit() public payable {
        balanceOf[msg.sender] += msg.value;
        emit Deposit(msg.sender, msg.value);
    }
    function withdraw(uint wad) public {
        require(balanceOf[msg.sender] >= wad);
        balanceOf[msg.sender] -= wad;
        msg.sender.transfer(wad);
        emit Withdrawal(msg.sender, wad);
    }

    function totalSupply() public view returns (uint) {
        return address(this).balance;
    }

    function approve(address guy, uint wad) public returns (bool) {
        allowance[msg.sender][guy] = wad;
        emit Approval(msg.sender, guy, wad);
        return true;
    }

    function transfer(address dst, uint wad) public returns (bool) {
        return transferFrom(msg.sender, dst, wad);
    }

    function transferFrom(address src, address dst, uint wad)
        public
        returns (bool)
    {
        require(balanceOf[src] >= wad);

        if (src != msg.sender && allowance[src][msg.sender] != uint(-1)) {
            require(allowance[src][msg.sender] >= wad);
            allowance[src][msg.sender] -= wad;
        }

        balanceOf[src] -= wad;
        balanceOf[dst] += wad;

        emit Transfer(src, dst, wad);

        return true;
    }
}

3、屏蔽不常用的接口

    由于Solidity单个智能合约编译之后的字节码体积不能超过24KB，所以单个.sol文件文件最好不要超过1000行，避免出现编译失败情况。
    可以通过注释掉.sol文件里不常用的函数或者接口，减少.sol编译之后的字节码体积，使其小于24KB。
    a) 注释掉sushiswap/contracts/uniswap2/UniswapV2Router02.sol里的4个函数：

// 注释掉UniswapV2Router02.sol这4个函数，以减少编译体积
//function _swapSupportingFeeOnTransferTokens()
//function swapExactTokensForTokensSupportingFeeOnTransferTokens()
//function swapExactETHForTokensSupportingFeeOnTransferTokens()
//function swapExactTokensForETHSupportingFeeOnTransferTokens()

    即屏蔽UniswapV2Router02.sol的第319行~第401行；

    b) 注释掉sushiswap/contracts/uniswap2/interface/IUniswapV2Router02.sol里的3个函数：

// 注释掉IUniswapV2Router02.sol这3个函数，以减少编译体积
//function swapExactTokensForTokensSupportingFeeOnTransferTokens()
//function swapExactETHForTokensSupportingFeeOnTransferTokens()
//function swapExactTokensForETHSupportingFeeOnTransferTokens()

    即屏蔽IUniswapV2Router02.sol的第25行~第45行。

4、编写部署脚本

    在sushiswap/contracts目录，新建一个2_deploy_contracts.js文件，内容如下：
    // sushiswap/contracts/2_deploy_contracts.js

const Factory = artifacts.require('uniswapv2/UniswapV2Factory.sol');
const Router = artifacts.require('uniswapv2/UniswapV2Router02.sol');
const WETH = artifacts.require('WETH.sol');
const MockERC20 = artifacts.require('MockERC20.sol');
const SushiToken = artifacts.require('SushiToken.sol');
const MasterChef = artifacts.require('MasterChef.sol');
const SushiBar = artifacts.require('SuShiBar.sol');
const SushiMaker = artifacts.require('SushiMaker.sol');
const Migrator = artifacts.require('Migrator.sol');
const web3_utils = require('web3-utils');

module.exports = async function(deployer, _network, address) {
    const [admin, _] = address;

    await deployer.deploy(WETH);
    const weth = await WETH.deployed();
    const tokenA = await MockERC20.new('Token A', 'TKA', web3_utils.toWei('1000'));
    const tokenB = await MockERC20.new('Token B', 'TKB', web3_utils.toWei('1000'));
    
    await deployer.deploy(Factory, admin);
    const factory = await Factory.deployed();
    await factory.createPair(weth.address, tokenA.address);
    await factory.createPair(weth.address, tokenB.address);
    await deployer.deploy(Router, factory.address, weth.address);
    const router = await Router.deployed();

    await deployer.deploy(SushiToken);
    const sushiToken = await SushiToken.deployed();

    await deployer.deploy(
        MasterChef,
        sushiToken.address,
        admin,
        web3_utils.toWei('100'),
        1,
        10
    );

    const masterChef = await MasterChef.deployed();
    await sushiToken.transferOwnership(masterChef.address);

    await deployer.deploy(SushiBar, sushiToken.address);
    const sushiBar = await SushiBar.deployed();

    await deployer.deploy(
        SushiMaker,
        factory.address,
        sushiBar.address,
        sushiToken.address,
        weth.address
    );
    const sushiMaker = await SushiMaker.deployed();
    await factory.setFeeTo(sushiMaker.address);

    await deployer.deploy(
        Migrator,
        masterChef.address,
        '0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f',
        factory.address,
        1
    );
};

5、部署Sushiswap-core

    a) 设置ganache的IP：127.0.0.1，端口为8545，HardFork选中Istanbul。
    由于UniswapV2的工厂合约、路由合约都使用的是Istanbul类型的硬分叉，所以，在ganache设置HARDFORK为Istanbul，然后重启ganache，如图(1)所示：

图(1) 在ganache里选中Istanbul硬分叉

    b) 打开一个黑框框终端，依次输入如下命令：

## 进入工程目录
cd sushiswap

## 进入truffle控制台
truffle console

## 编译智能合约
compile

## 部署sushiswap
migrate -f 2 --to 2 

    效果如图(2)、图(3)所示：
