Investigation Report: Zyfai Rebalancer Agent (8453:2117)
Summary
Zyfai Rebalancer Agent for 0xB4c7...D869 is a per-wallet DeFi rebalancing agent on Base, part of the Zyfai platform. It claims to use ZK proofs for validating yield opportunities across Base, Arbitrum, and Plasma. The technical infrastructure is impressive — working website, documentation, live MCP server with 15 tools, and a real GitHub repo with ZK circuit implementations. However, the on-chain footprint is extremely thin (1 transaction, zero balance), and there is no visible social media presence or community engagement.
Verdict: 🟡 Yellow (55/100)
