Ghostfund demo

Description

GhostFund is a private DeFi yield vault built for the Chainlink Convergence hackathon. It uses three Chainlink primitives working together to solve a core problem in DeFi: every transaction is public, exposing fund managers to MEV attacks and front-running. How it works: CRE monitors Aave V3 lending rates every 5 minutes and generates signed yield recommendations with a 1-hour TTL. The vault owner reviews each recommendation before any funds move. No automated execution without human approval. Private Transactions handle fund distribution so sender identity stays hidden. Recipients redeem funds using cryptographic withdraw tickets authorized through EIP-712 signatures. ACE enforces three on-chain compliance policies through a PolicyEngine: address allowlists (AllowPolicy), per-deposit caps (MaxPolicy), and an emergency pause circuit breaker (PausePolicy). A custom DepositExtractor parses vault calldata for policy evaluation. Tech stack: Solidity, Foundry, Next.js, TypeScript, Tailwind, wagmi, viem
