Yield Aggregator

This project is a cross-chain yield farming optimizer that leverages 1inch Fusion+ technology to help users maximize their DeFi returns by automatically identifying and executing profitable yield opportunities across multiple blockchain networks. The platform continuously monitors yield rates across major DeFi protocols (Aave, Compound, Curve) on Ethereum, Polygon, Arbitrum, Base, and Optimism. When it detects a more profitable opportunity, it calculates the optimal execution path using 1inch Fusion+ for cross-chain swaps, ensuring minimal gas costs and maximum efficiency. Key features include real-time yield comparison, intelligent cost-benefit analysis, automated execution strategies, and comprehensive risk assessment. The system supports major stablecoins (USDC, USDT, DAI) and popular yield-bearing tokens, providing users with a seamless way to optimize their DeFi portfolios without manual intervention. The platform addresses the fragmented nature of DeFi liquidity by providing a unified interface for cross-chain yield optimization, helping users navigate the complex landscape of multiple chains and protocols while maximizing their returns.

This project is built using the T3 Stack (Next.js 15, TypeScript, tRPC, Prisma, Tailwind CSS) for a type-safe, full-stack development experience. The frontend features a modern React interface with real-time data visualization and interactive yield comparison tools. The core yield aggregation system integrates with multiple DeFi protocols through custom adapters, fetching real-time APY data from Aave and other major lending platforms. The cross-chain functionality is powered by 1inch Fusion+ SDK, enabling atomic cross-chain swaps with minimal slippage and optimal gas efficiency. The backend uses tRPC for type-safe API communication between frontend and server, while Prisma handles database operations for storing yield opportunities and user positions. The system implements intelligent caching strategies to minimize API calls and ensure fast response times. A particularly innovative aspect is the real-time profitability calculator that factors in gas costs, bridge fees, and execution timing to determine the optimal yield migration strategy. The platform also includes comprehensive risk scoring algorithms that evaluate protocol security, liquidity depth, and historical performance. The deployment is managed through PM2 for production-grade process management, ensuring high availability and automatic restarts. The entire system is designed to be modular and extensible, allowing for easy integration of new protocols and chains as the DeFi ecosystem evolves.
