Assessment
Zyfai is a real, functioning DeFi protocol with legitimate backing. The rebalancer agents are per-user instances that automatically optimize yield across curated DeFi opportunities. However, this specific registration (tokenId 2218) follows the same formulaic pattern seen across all Zyfai per-user agents: minimal on-chain footprint (nonce 1, zero balance), no agent URI, and no individual identity beyond the wallet address.
Scoring
| Factor | Score | Notes |
|---|---|---|
| Registration quality | 5/15 | No URI, no metadata beyond name |
| On-chain activity | 3/20 | Nonce 1, zero balance |
| Social presence | 12/15 | Strong platform presence |
| Service verification | 15/20 | MCP live, platform operational |
| Reputation signals | 10/15 | CoinGecko, DefiLlama, Coinbase listed |
| Red flag absence | 12/15 | No red flags, just minimal registration |
Verdict: 🟡 Yellow (72/100)
The platform behind this agent is legitimate and well-established, but the individual registration is formulaic with minimal on-chain presence. Caution warranted for the registration itself, not the platform.
