AlphaFlow

AlphaFlow is an autonomous multi-chain DeFi yield optimization platform that solves the problem of yield fragmentation across different blockchains. The platform aggregates real-time APY data from Aave V3 across multiple chains (Ethereum, Polygon, Base, Avalanche) and automatically identifies the highest-yielding opportunities for users.

Key features include:

Multi-Chain Intelligence: Real-time APY comparison across 5+ supported chains APY Optimization Engine: Automatic detection of better yield opportunities with calculated additional earnings One-Click Cross-Chain Execution: Seamless bridging and supplying to optimal chains via Avail Nexus Smart Contract Integration: Direct integration with Aave V3 pools using official address books User-Friendly Interface: Intuitive UI showing current vs optimized yields with clear benefit calculations The platform eliminates the need for users to manually check yields across different chains, handle complex bridging, and manage multiple transactions. Instead, users can optimize their DeFi yields with a single click, automatically moving funds to the chain offering the best APY while maintaining full custody of their assets.

This project leverages cutting-edge Web3 technologies in a sophisticated multi-chain architecture:

Frontend Stack:

React 19 with TypeScript for type safety and modern UI patterns Wagmi v2 + RainbowKit for comprehensive wallet integration Custom React hooks for multi-chain state management Lucide React for consistent iconography Tailwind CSS for responsive design Blockchain Integration:

@aave/react SDK for real-time APY data from official Aave V3 pools @bgd-labs/aave-address-book for verified contract addresses across chains Viem for low-level blockchain interactions Custom multi-chain hooks that fetch data simultaneously from 5 chains Cross-Chain Infrastructure:

Avail Nexus Widgets: The key innovation enabling seamless cross-chain operations BridgeAndExecuteButton component for one-click bridge + supply operations Custom optimization algorithms that calculate best APY chains in real-time Smart contract parameter building for different chain configurations Notable Technical Achievements:

Concurrent Multi-Chain Data Fetching: Custom useMultiChainAaveData hook fetches APY data from all supported chains simultaneously Dynamic Chain Configuration: Automatic pool address and asset mapping based on target chains Real-Time Optimization Detection: Algorithm continuously monitors for better yield opportunities Seamless UX: Complex cross-chain operations abstracted into single-click actions Partner Technology Benefits:

Avail DA Layer: Enables efficient cross-chain bridging with lower costs and better UX Aave V3 SDK: Provides accurate, real-time market data and ensures compatibility RainbowKit: Streamlines wallet connections across multiple chains Hacky/Notable Implementation:

Built a custom getBestAPY function that dynamically compares yields across chains and calculates optimization benefits Implemented error handling for chain icons with fallback mechanisms Created a filtering system that hides chains with errors or unavailable data Developed dynamic contract parameter building that adapts to different chain asset configurations
