Investigation Report: Zyfai Rebalancer Agent (8453:1980)
Summary
Zyfai Rebalancer Agent for wallet 0xEf6538B5056B6C215c7919DE37E46130D6b305A1 is a per-wallet registration from the Zyfai/Ondefy project on Base chain. The underlying project is legitimate with real ZK technology, a functioning MCP server, and open-source code. However, this specific registration has minimal on-chain activity and zero ETH balance.
Verdict: 🟡 YELLOW (62/100)
Registration Data
- Token ID: 1980 on Base (chain 8453)
- Owner: 0xEf6538B5056B6C215c7919DE37E46130D6b305A1
- URI: IPFS-hosted, valid JSON with complete metadata
- Status: Active
- Endpoints: Website (zyf.ai), MCP server (mcp.zyf.ai)
- Technology: Circom 2.2.2+, SnarkJS 0.7.5 (Groth16)
- Chains: Base, Arbitrum, Plasma
On-Chain Analysis
- Owner wallet has 1 transaction and 0 ETH balance on Base
- Registration exists but wallet shows minimal activity
- No agent wallet configured separately from owner
Service Verification
- MCP Server (mcp.zyf.ai): ✅ Live, returns valid server info with 15 DeFi tools across 5 categories (Protocol, Opportunities Discovery, Analytics & Metrics, User Data, Earnings)
- Website (zyf.ai): ✅ Loads successfully
- GitHub (ondefy/erc8004-implementation): ✅ Real repository with ZK circuits, Circom + Groth16, ERC-8004 integration, Solidity verifier contracts
Social & Web Presence
- Project is backed by Ondefy, a known DeFi project
- Open-source codebase with proper documentation
- NPM package published (@zyfai/sdk)
Cross-Reference
- Sibling registration: Token 2100 (8453:2100) is the same project for a different wallet — previously investigated and scored 64 (Yellow)
- Pattern: Zyfai creates per-wallet agent registrations, each with identical metadata except the wallet address
- This is a valid pattern for user-specific agents but results in many near-identical registrations
Scoring Breakdown
| Factor | Score | Notes |
|---|---|---|
| Registration quality | 13/15 | Complete IPFS metadata, all fields present |
| On-chain activity | 5/20 | Only 1 tx, 0 balance — very thin footprint |
| Social presence | 11/15 | Real project, GitHub, website, NPM |
| Service verification | 16/20 | MCP live with 15 tools, website loads |
| Reputation signals | 5/15 | 1 existing feedback, sibling scored yellow |
| Red flag absence | 12/15 | No red flags, but per-wallet clone pattern is notable |
| Total | 62/100 |
Conclusion
Legitimate technology from a real project, but the per-wallet registration model means each individual agent has minimal unique on-chain presence. The MCP server and ZK tech are genuine strengths. Caution warranted due to thin wallet activity.
