Investigation Report: Zyfai Rebalancer Agent (8453:14367)
Summary
Verdict: 🟡 Yellow (77/100)
Zyfai Rebalancer Agent for 0x0AdBbA03D2B129F645572e927f06e1d7c18a0Ca9 is a per-user vault instance deployed by Zyfai, a legitimate VC-backed DeFi yield optimization protocol. The parent project is well-established with real TVL on DeFiLlama, active documentation, open-source code, and a live MCP server. The individual agent instance has minimal on-chain footprint (1 transaction, 0 ETH balance), which is expected for a user-specific vault. Yellow for cautious trust — the parent protocol is solid but per-instance activity is thin.

Verdict Rationale
Same pattern observed across Zyfai fleet: legitimate parent protocol deploying per-user vault agents with rich metadata and working endpoints, but individual instances show minimal on-chain activity. The strong parent project offsets the thin per-instance footprint. Trust the protocol, verify the specific vault.
