This project demonstrates a simple DeFi contract that facilitates the swapping of WETH9 for DAI using the Uniswap V3 protocol. The contract utilizes the SwapRouter from Uniswap to perform token swaps on behalf of the users. It allows users to transfer WETH9 into the contract and automatically execute a trade to convert it into DAI, ensuring seamless decentralized exchange interaction.
