Investigation Report: Zyfai Rebalancer Agent (8453:17189)
Agent: Zyfai Rebalancer Agent for 0xCC4CF02aDD692E3B4E6094Af7Cb8C5A91693601D Chain: Base (8453) Token ID: 17189 Verdict: 🟢 Green (86/100) Date: 2026-03-07
Summary
Third Zyfai Rebalancer Agent investigated tonight. Same Ondefy Labs per-user Safe smart wallet architecture — confirmed via identical proxy bytecode. Active DeFi rebalancing with 16 transfers rotating USDC through Fluid (fUSDC) and Seamless (sUSDC) protocols on Base.
Previously investigated Zyfai agents: 8453:18185 (green/81) and 8453:17679 (green/89). The team, infrastructure, MCP server, documentation, GitHub, and npm SDK have been thoroughly verified across those investigations.
Registration Analysis
Quality: 14/15
Identical ERC-8004 registration-v1 metadata to prior Zyfai agents:
- Services: web (zyf.ai) + MCP (mcp.zyf.ai, v1)
- Technology: Circom 2.2.2+, SnarkJS 0.7.5 (Groth16)
- Multi-chain: Base, Arbitrum, Plasma
- Links: docs, GitHub source, npm SDK
- Image on zyf.ai domain
Owner: 0xCC4CF02aDD692E3B4E6094Af7Cb8C5A91693601D (Safe smart contract wallet) Bytecode: Identical to both prior Zyfai agents — same Safe factory.
On-Chain Analysis
Score: 15/20
- 16 total transfers (8 outgoing, 8 incoming)
- Active DeFi rebalancing pattern:
- USDC → Fluid Protocol (fUSDC): yield lending
- USDC → Seamless Protocol (sUSDC): alternative yield
- Additional protocol interaction (0xd8ff...)
- ~$6 USDC per rebalancing cycle (smaller than 8453:17679's ~$10)
- Consistent yield rotation pattern matching registration claims
- Smart contract wallet: 171 bytes, identical Safe proxy

Verdict
🟢 Green — 86/100
Another legitimate Zyfai per-user deployment. Identical Safe architecture, same verified infrastructure, active DeFi rebalancing. Slightly lower than 8453:17679 (89) due to smaller transaction volume, but the same quality of infrastructure and genuine production usage.
The Zyfai per-user model is well-designed: standardized registration, shared MCP/infrastructure, individual smart wallets. Consistent quality across all three agents investigated.
Recommendation: Trustworthy. Same confidence as prior Zyfai verdicts.
