yarn install

Setup

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

npm install sol-merger -g

Prepare PancakeFactory and PancakeRouter

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

Deploy PancakeFactory and PancakeRouter

Deploy WBNB

Deploy PancakeFactory

  • New File: PancakeFactory.sol => Copy source from ./build/PancakeFactory.sol
  • Compiler tab => Select compiler: v0.5.16+commit.9c3226ce
  • Deploy tab => Select PancakeFactory -> Fill your address as feeToSetter in constructor -> Deploy

Deploy PancakeRouter01

  • New File: PancakeRouter01.sol => Copy source from ./build/PancakeRouter01.sol
  • Expand PancakeFactory deployed above -> Read INIT_CODE_PAIR_HASH -> Copy this hash without prefix 0x. Ex: bb600ba95884f2c2837114fd2f157d00137e0b65b0fe5226523d720e4a4ce539
  • Edit PancakeRouter01: Find PancakeLibrary -> pairFor function => Replace new hex by INIT_CODE_PAIR_HASH above. Ex: hex'd0d4c4cd0848c93cb4fd1f498d7013ee6bfb25783ea21593d5834f5d250ece66' -> hex'bb600ba95884f2c2837114fd2f157d00137e0b65b0fe5226523d720e4a4ce539'
  • Compiler tab => Select compiler: v0.6.6+commit.6c089d02
  • Deploy tab => Select PancakeRouter01 -> Fill PancakeFactory address and WBNB address as constructor params -> Deploy

Deploy PancakeRouter (Main Router)

  • New File: PancakeRouter.sol => Copy source from ./build/PancakeRouter.sol
  • Expand PancakeFactory deployed above -> Read INIT_CODE_PAIR_HASH -> Copy this hash without prefix 0x. Ex: bb600ba95884f2c2837114fd2f157d00137e0b65b0fe5226523d720e4a4ce539
  • Edit PancakeRouter: Find PancakeLibrary -> pairFor function => Replace new hex by INIT_CODE_PAIR_HASH above. Ex: hex'd0d4c4cd0848c93cb4fd1f498d7013ee6bfb25783ea21593d5834f5d250ece66' -> hex'bb600ba95884f2c2837114fd2f157d00137e0b65b0fe5226523d720e4a4ce539'
  • Compiler tab => Select compiler: v0.6.6+commit.6c089d02; Check on Enable optimization: 200 to avoid Contract code size limit issue
  • Deploy tab => Select PancakeRouter -> Fill PancakeFactory address and WBNB address as constructor params -> Deploy

Setup Frontend

  • Update .env
cd pancake-swap-interface-v1
cp .env.development .env

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

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

    • Change from supportedChainIds: [56, 97] to supportedChainIds: [97]
    • Change from 56 to 97

  • 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

  • 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
