CrossYield

An AI-powered decentralized finance yield optimizer that enables automatic cross-chain asset rebalancing using real-time oracle data and smart automation. The project integrates multiple sponsor technologies to deliver seamless multi-chain yield maximization with minimal user involvement.

Frontend: Next.js 15 + TypeScript + TailwindCSS for a responsive, wallet‑connected UI. Uses Reown AppKit for wallet management and network detection. Integrates Avail Nexus SDK directly into the React stack for cross‑chain bridge operations.

Backend: Python serving yield data and AI analysis endpoints. Groq LLM provides reasoning for optimal farm selection. Live APY and price data fetched from Pyth Network and DeFi APIs.

Smart Contracts: Solidity + Hardhat deployment on Sepolia Testnet. Simple vault contract handles deposits, withdrawals, and emits events that are indexed using Envio HyperIndex for dashboard tracking. Contracts verified and viewable via Blockscout SDK integration.

Automation & Data Flow: User deposits test tokens. Backend AI fetches oracle data. Bridge transaction through Avail Nexus. Automation trigger via Lit Protocol Vincent handles rebalancing when APY drops. Envio HyperIndex and Blockscout keep everything transparent.
