Deploy WBNB

• New File: WBNB.sol => Copy source from https://gist.github.com/nhancv/b0b35f16472e4998d0fd17b7a1e4f707
• Compiler tab => Select compiler: v0.8.3+commit.8d00100c
• Deploy tab => Select WBNB -> Deploy

Deploy PancakeFactory

• New File: PancakeFactory.sol => Copy source from ./build/PancakeFactory.sol
• Compiler tab => Select compiler: v0.5.16+commit.9c3226ce

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: 9fe1b508f2b0a84ca3b07189bfa32dd3309fb04b5ddec5e0456a232004b07194
• Edit PancakeRouter01: Find PancakeLibrary -> pairFor function => Replace new hex by INIT_CODE_PAIR_HASH above. Ex: hex'd0d4c4cd0848c93cb4fd1f498d7013ee6bfb25783ea21593d5834f5d250ece66' -> hex'9fe1b508f2b0a84ca3b07189bfa32dd3309fb04b5ddec5e0456a232004b07194'
• 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: 9fe1b508f2b0a84ca3b07189bfa32dd3309fb04b5ddec5e0456a232004b07194
• Edit PancakeRouter: Find PancakeLibrary -> pairFor function => Replace new hex by INIT_CODE_PAIR_HASH above. Ex: hex'd0d4c4cd0848c93cb4fd1f498d7013ee6bfb25783ea21593d5834f5d250ece66' -> hex'9fe1b508f2b0a84ca3b07189bfa32dd3309fb04b5ddec5e0456a232004b07194'
• 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
