GhostFund is a private DeFi yield vault deployed on Sepolia that solves a core problem in DeFi: every transaction is public, exposing fund managers to MEV attacks and front-running.

It uses three Chainlink primitives working together. 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. Private Transactions handle fund distribution so sender identity stays hidden, using EIP-712 authorization and cryptographic withdraw tickets. ACE enforces three on-chain compliance policies: address allowlists, per-deposit caps, and an emergency pause circuit breaker.
