如何将PancakeSwap部署到以太坊类链上

这个教程只包含部署了swap和liquidity功能

准备源码

下载pancake-swap-core源码

• Clone pancake-swap-core

git clone git@github.com:pancakeswap/pancake-swap-core.git
cd pancake-swap-core
git checkout -b factory 3b214306770e86bc3a64e67c2b5bdb566b4e94a7
yarn install
yarn compile

下载pancake-swap-periphery源码

• Clone pancake-swap-periphery

git clone git@github.com:pancakeswap/pancake-swap-periphery.git
cd pancake-swap-periphery
git checkout -b router d769a6d136b74fde82502ec2f9334acc1afc0732
yarn install
yarn add @uniswap/v2-core@"file:../pancake-swap-core"
yarn compile

下载pancake-swap-interface-v1前端源码

• Clone pancake-swap-interface-v1

git clone git@github.com:pancakeswap/pancake-swap-interface-v1.git
cd pancake-swap-interface-v1
git checkout -b v1 0257017f2daaae2f67c24ded70b5829f74a01b3c
yarn install

安装

Install contract merger: https://www.npmjs.com/package/sol-merger

下载合约合并工具

npm install sol-merger -g

Prepare PancakeFactory and PancakeRouter

因为PancakeFactory和PancakeRouter的合约代码是好几个文件，我们把它们合并成一个方便部署，都放到build目录下

sol-merger pancake-swap-core/contracts/PancakeFactory.sol ./build
sol-merger pancake-swap-core/contracts/PancakePair.sol ./build
sol-merger pancake-swap-periphery/contracts/PancakeRouter01.sol ./build
sol-merger pancake-swap-periphery/contracts/PancakeRouter.sol ./build

Prepare WBNB.soland other tokens

准备WBNB.sol和其他咱们想在链上部署的token的合约代码，我都整理到了build/tokens目录下

Setup Frontend

安装前端代码

• Update .env.development

修改配置文件

• 修改REACT_APP_NETWORK_URL 为网络的RPC的URL
• 修改REACT_APP_CHAIN_ID 为网络的chainID

更新部署的PancakeRouter地址

• Update PancakeRouter address to ROUTER_ADDRESS at src/constants/index.ts

更新所有链的chainId，我这里是chainId是269

• Update support chain to testnet at src/connectors/index.ts

  • Change from supportedChainIds: [56, 97] to supportedChainIds: [269]
  • Change from 56 to 269
• Update support chaindId 97to269 at src/connectors/index.ts, src/utils/index.ts

更新部署的PancakeFactory地址 和 init code hash

• Update PancakeFactory address and code hash to FACTORY_ADDRESS and INIT_CODE_HASH at node_modules/@pancakeswap-libs/sdk/dist/constants.d.ts, node_modules/@pancakeswap-libs/sdk/dist/sdk.cjs.development.js, node_modules/@pancakeswap-libs/sdk/dist/sdk.cjs.production.min.js and node_modules/@pancakeswap-libs/sdk/dist/sdk.esm.js
• Update PancakeFactory address to v2 factory; PancakeRouter01 address to v2 router 01 and PancakeRouter address to v2 router 02 at src/state/swap/hooks.ts

更新所有WBNB地址

• Update WBNB address at node_modules/@pancakeswap-libs/sdk/dist/sdk.cjs.development.js, node_modules/@pancakeswap-libs/sdk/dist/sdk.cjs.production.min.js, node_modules/@pancakeswap-libs/sdk/dist/sdk.esm.js

更新所有 MULTICALL_NETWORKS 地址，你用测试网的就修改测试网，主网就修改主网的

• Update MULTICALL_NETWORKS address src/constants/multicall/index.ts

更新所有token的地址在src/constants/index.ts，并且除了这里

const WETH_ONLY: ChainTokenList = {
  [ChainId.MAINNET]: [WETH[ChainId.MAINNET]],
  [ChainId.BSCTESTNET]: [WETH[ChainId.BSCTESTNET]],
}

把ChainId.MAINNET换成ChainId.BSCTESTNET

export const CAKE = new Token(ChainId.BSCTESTNET, '0x4B13a328AFcc7EA26FA97436fB8a7346e6d2A6C6', 18, 'CAKE', 'PancakeSwap Token')
export const WBNB = new Token(ChainId.BSCTESTNET, '0x3180356fa8082efEEf9523BE654c162242E4dcC0', 18, 'WBNB', 'Wrapped BNB')
export const DAI = new Token(ChainId.BSCTESTNET, '0x9D575ba54c57763d3b1e42957eBFE9D791DeeD39', 18, 'DAI', 'Dai Stablecoin')
export const BUSD = new Token(ChainId.BSCTESTNET, '0x7560AdfEca32ed5EC1b9101dD458e867Aec90cE3', 18, 'BUSD', 'Binance USD')
export const USDT = new Token(ChainId.BSCTESTNET, '0x02e996E902F5Ad8cC5037ECC5DCd552C565B6EBC', 18, 'USDT', 'Tether USD')
export const ETH = new Token(ChainId.BSCTESTNET, '0xc34ad7105eb3B5F6c7A0198A346E26595A142291', 18, 'ETH', 'Binance-Peg Ethereum Token')
export const BAKE = new Token(ChainId.BSCTESTNET, '0x94a42146Fab15a7EC00a8Bd95720cF0baDa65B42', 18, 'BAKE', 'BAKE Token')

更新和 pancake-swap-interface-v1/src/constants/token/pancakeswap.json 将部署的token的address、chainId替换掉，logoURI可以替换成可以显示logo路径。

检查所有需要替换的都替换了

• VERIFY CHANGES by Find All old addresses and replace new ones:

  • MULTICALL_NETWORKS: 0x301907b5835a2d723Fe3e9E8C5Bc5375d5c1236A

修改配置只显示swap和liquidity功能

• Custom menu at src/components/Menu/config.ts

import { MenuEntry } from '@pancakeswap-libs/uikit'

const config: MenuEntry[] = [
  {
    label: 'Home',
    icon: 'HomeIcon',
    href: '/',
  },
  {
    label: 'Trade',
    icon: 'TradeIcon',
    initialOpenState: true,
    items: [
      {
        label: 'Exchange',
        href: '/swap',
      },
      {
        label: 'Liquidity',
        href: '/pool',
      },
    ],
  },
]

export default config

添加自己token

• Deploy your own tokens
  • Deploy your own tokens and update info (token address + chainId to 97) to src/constants/token/pancakeswap.json
  • Remember update token icon with name as token address in lowercase mode to public/images/coins
  • Update support network from ChainId.MAINNET to ChainId.BSCTESTNET at src/constants/index.ts
  • Update coin addresses to your at src/constants/index.ts
  • Update src/components/Menu/index.tsx: From priceData.data[CAKE.address].price to priceData.data[CAKE.address]?.price ?? 0
  • Update src/hooks/useGetDocumentTitlePrice.ts: From priceData.data[CAKE.address].price to priceData.data[CAKE.address]?.price ?? 0
