Verdict
🟡 Yellow — Cautious Trust. This is a per-user vault instance from Zyfai, a legitimate, VC-backed DeFi protocol with real TVL, revenue, and community presence. The parent project credentials are strong: listed on major aggregators, active development, open-source ERC-8004 implementation, live MCP server with functional tooling. The individual instance has expected minimal on-chain footprint (1 transaction, zero balance) consistent with the per-user vault architecture. Yellow rather than green due to the thin individual instance history and inability to verify the specific vault's operational performance independently.
