A simple Uniswap V2-style token swap interface built with HTML + JS + MetaMask + Ethers.js.

• Frontend: public/index.html, public/swap.js
• Example contracts: contract/factory.sol, contract/router.sol (placeholders for your own UniswapV2-compatible contracts)

If you want your own Factory/Router. The repo includes placeholders in contract/ — you can replace them or point to your own.

1. Deploy contracts

   • Deploy your Factory contract.
   • Deploy your Router contract and link it to the Factory.

2. Prepare tokens

   • Add liquidity or approve token spending for the Router.

3. Configure frontend

   • Update routerAddress in swap.js.

4. Run locally

   cd public
   python3 -m http.server
   
   

Once deployed, update the frontend addresses:

• Open public/swap.js
• Set routerAddress to your deployed router
• Update tokenAddresses to the ERC-20 tokens on your network
