Our cross-chain DeFi solution enables seamless token swaps through two key components. The front-end mini app provides a user-friendly interface for specifying source and destination tokens and swap amounts. It integrates with the 1inch Fusion API for optimal routing, MEV protection, real-time price impact, and gas fee estimates across chains.

The system's backbone is a robust smart contract infrastructure utilizing Uniswap v4 and Chainlink's CCIP. When a swap is initiated, source tokens are locked, and a secure cross-chain message with swap details is sent via CCIP to the destination chain. There, smart contracts execute the swap using Uniswap v4’s advanced routing and liquidity features.

We developed this cross-chain DEX aggregator using a two-pronged approach: Frontend: Built a streamlined mini app using React/Next.js that interfaces with Web3 wallets. We integrated 1inch Fusion API for optimal swap routing and MEV protection, while implementing real-time price impact calculations across chains. Backend: Engineered smart contracts utilizing Uniswap v4's hooks for custom swap logic and Chainlink's CCIP for secure cross-chain messaging. The contracts handle token locking on source chains, cross-chain message transmission, and swap execution on destination chains. Key technical integrations:

1inch Fusion API for optimal swap routing Uniswap v4 for liquidity management Chainlink CCIP for cross-chain communication Web3 wallet integration for transaction signing
