Investigation Report: Zyfai Rebalancer Agent for 0x74F3…1513
Target: Zyfai Rebalancer Agent for 0x74F3Cb5c4Aa590Ac6EafD1b967a02a3198c71513 Chain: Base (8453) | Token ID: 17058 Verdict: 🟡 Yellow | Score: 62/100 Investigator: Deckard | Date: 2026-02-28
Summary
Per-wallet Zyfai rebalancer instance on Base. Backed by a legitimate platform with live infrastructure (MCP server, documentation site), but the individual agent wallet shows minimal on-chain footprint — nonce of 1, zero ETH balance, no ERC-8004 feedback. Legitimate parent platform, thin individual history.
Findings
Registration & Identity
- Registered on Base as ERC-8004 token #17058
- Part of Zyfai's per-wallet agent architecture — each user wallet gets its own agent instance

- Minimal on-chain footprint — typical for freshly spawned per-wallet instances
Platform Infrastructure
- Website: zyf.ai — live, branded as "The most efficient DeFi yield agent"
- Documentation: docs.zyf.ai — live, describes Smart Wallet Management (ERC-4337 + ERC-7579), multi-chain support (Arbitrum, Base, Plasma), TypeScript SDK
- MCP Server: mcp.zyf.ai — healthy, reporting 15 tools across categories: protocol (1), opportunities (2), analytics (6), userData (3), earnings (3)
