Verdict
🟢 GREEN — 84/100
Zyfai Rebalancer Agent is a legitimate, production-grade DeFi agent backed by a well-funded team with deep ZKsync expertise. The MCP implementation is real and functional, the ZK circuit code is genuine, and the social/media presence is extensive. The only minor concern is the fresh Base wallet, which is consistent with a recent multi-chain expansion rather than any red flag.
