[whiteyhat]

Description

Implement a feature that allows users to perform token swaps directly within the application using the Uniswap API. This will enable seamless in-dapp swapping functionality, enhancing user convenience and engagement.

Acceptance Criteria

• Integrate the Uniswap API to enable token swap functionality.
• Provide a user-friendly interface for selecting tokens, entering amounts, and confirming swaps.
• Display real-time swap rates, fees, and slippage tolerance options.
• Handle errors gracefully, such as insufficient liquidity, gas estimation errors, or invalid user input.
• Ensure successful transactions are reflected in the user's wallet and transaction history.

Technical Details

• API Integration: Use the [Uniswap API](https://docs.uniswap.org/) or relevant SDKs (e.g., @uniswap/sdk) for swap functionality.
• Frontend: Build a clean and intuitive swap UI with token selection, input fields, and confirmation dialogs.
• Backend: Optional – include server-side validation or handling for swap-related data.
• Security: Ensure that user interactions and transactions are secure, leveraging wallet signing (e.g., via Web3.js or Ethers.js).
• Gas Optimization: Provide users with an estimated gas fee and optimize transactions where possible.
