V2 SDK for the BSC testnet

Since there isn’t an official PancakeSwap on testnet and the v2 frontend swap interface code isn’t published on the PancakeSwap github I decided to adjust pancake-swap-interface-v1 for v2 routers on the BSC testnet as per this comment on issue #365.

This fork requires a fork of cd3d-dex-libs-sdk, instructions and code can at https://github.com/ibhagwan/pancakeswap-sdk-v2.

Step 1: Build pancakeswap-sdk-v2

❯ git clone https://github.com/pancakeswap/pancakeswap-sdk-v2
  • Modify FACTORY_ADDRESS & INIT_CODE_HASH in src/constants.ts
  • Modify the testnet WBNB at the end of entities/token.ts:

    [ChainId.BSCTESTNET]: new Token(
        'Wrapped BNB'

Note: if you’d like to use the default testnet router 0xD99D1c33F9fC3444f8101754aBC46c52416550D1 you can skip the editing and git clone https://github.com/ibhagwan/pancakeswap-sdk-v2.git instead.


❯ yarn
❯ npm run build

Step 2:

Clone and branch to the commit before V2 changes:

❯ git clone https://github.com/pancakeswap/pancake-swap-interface-v1
❯ git branch pancake_v2 0257017
❯ git checkout pancake_v2

Create .env with the below contents:


Modify ROUTER_ADDRESS in src/constants/index.ts

Edit the tokens you’d like to appear in the UI in src/constants/token/pancakeswap.json (change the token address and set chainId to 97)

Search the entire project for 'cd3d-dex-libs-sdk' and replace with 'cd3d-dex-libs-sdk'

I do this with vim, search the entire project with fzf|rg into a quickfix list and use
:cdo %s/'@pancakeswap-libs\/sdk'/'@pancakeswap-libs\/sdk-v2'/g

❯ yarn
❯ npm install ../pancakeswap-sdk-v2
❯ rm -rf ./node_modules/cd3d-dex-libs-sdk
❯ yarn start
