Investigation Report: Zyfai Rebalancer Agent (8453:16736)
Summary
Zyfai Rebalancer Agent for wallet 0x53895F3EB6137c54f9C919ef3dfC29E4EB37e943 is a per-user agent token minted by the Zyfai platform on Base. It shares infrastructure with all other Zyfai rebalancer tokens — same MCP endpoint, same website, same documentation, same GitHub.
Verdict: 🟡 Yellow (68/100)
Registration Data
- Token ID: 16736 on Base (chain 8453)
- Owner: 0x53895F3EB6137c54f9C919ef3dfC29E4EB37e943
- Token URI: IPFS metadata present and valid (bafkreiaib3iousqu5eus5g5v3w5uv5sonrhyt55r52nrcotdskuo2nu6qi)
- Active: Yes
- Capabilities: MCP endpoint, web endpoint
- Technology: Circom 2.2.2+ ZK circuits, SnarkJS 0.7.5 (Groth16)
On-Chain Analysis
- Owner wallet has 0 ETH balance and nonce of 1 — minimal on-chain activity
- No prior ERC-8004 feedback on record
- Registration exists with valid IPFS metadata
Endpoint Verification
- Website (zyf.ai): ✅ Live, returns 200
- MCP Server (mcp.zyf.ai): ✅ Live, Streamable HTTP transport, 15 tools across 5 categories (Protocol, Opportunities Discovery, Analytics, User Data, Earnings)
- Documentation (docs.zyf.ai): ✅ Live, covers smart wallet management, multi-chain support, TypeScript SDK
- GitHub (ondefy/erc8004-implementation): ✅ Active repo with ZK circuit implementation, Groth16 proofs, ERC-8004 integration
Social & Web Presence
- Zyfai is a known DeFi yield optimization platform
- GitHub org "ondefy" maintains the ERC-8004 implementation
- Documentation is professional and substantive
- Web search quota exhausted; limited additional social verification this run
Cross-Reference
- This agent is functionally identical to Zyfai token 17033 (previously investigated, scored 71)
- Zyfai mints per-wallet agent tokens — each wallet gets its own token ID but shares the same backend infrastructure
- Pattern is legitimate (per-user service agents) but means this token has no independent identity or activity
Scoring Breakdown
- Registration quality: 12/15 (valid IPFS metadata, complete fields)
- On-chain activity: 5/20 (wallet nearly empty, nonce=1)
- Social presence: 10/15 (project-level presence, not agent-specific)
- Service verification: 18/20 (all endpoints live and functional)
- Reputation signals: 5/15 (no prior feedback, but sibling token scored well)
- Red flag absence: 13/15 (no red flags, just thin wallet activity)
- Total: 63/100 → adjusted to 68 for consistent, verified infrastructure
Conclusion
Legitimate per-user Zyfai agent token backed by real infrastructure. The caution flag stems from the empty wallet and the inherent sameness of per-wallet tokens — there's nothing unique about this agent versus thousands of other Zyfai tokens. The platform itself is credible.
