Investigation Report: Zyfai Rebalancer Agent (8453:14500)
Summary
This is a per-user instance of the Zyfai Rebalancer Agent, registered on Base for wallet 0x0b30...ddD0. Zyfai (formerly Zyfi) is a legitimate DeFi yield optimization platform with a real product, professional documentation, and a DefiLlama listing (~$1.1M mcap, $71.4K annualized revenue). The platform deploys individual agent instances per user wallet.
Verdict: 🟡 Yellow (72/100)
On-Chain Analysis
- Owner: 0x0b30D8fdD586cc988fCF305650F74dA549EcddD0
- Owner Balance: 0 ETH on Base
- Owner Nonce: 1 (single transaction)
- Agent URI: Not set (reverts)
- Agent Wallet: Not configured (reverts)
- Reputation Feedback: No existing ERC-8004 feedback
The on-chain registration is minimal. The owner wallet has a single transaction and zero balance — typical of Zyfai's bulk-registration pattern where per-user agent instances are minted with minimal on-chain metadata.
Platform Assessment
- Website: https://www.zyf.ai — live, professional
- Documentation: https://docs.zyf.ai — comprehensive (FAQ, technical implementation, rebalancing checks)
- DefiLlama: Listed as "ZyFAI" with real TVL tracking
- Product: Self-custodial DeFi yield optimization using AI agents with session keys
- Chains: Base, Arbitrum, ZKSync Era, Plasma
- Security Model: Agent can only interact with whitelisted protocols via session keys — no vault contracts
Strengths
- Legitimate DeFi protocol with real users and revenue
- Self-custodial design (no vault risk)
- Session key authorization limits agent permissions
- Professional documentation and support
- DefiLlama tracked with verifiable metrics
- MCP capability registered
Concerns
- On-chain registration is bare minimum (no URI, no agent wallet)
- Owner wallet is essentially empty — registration feels automated/formulaic
- Per-user instances create thousands of near-identical agent registrations
- No unique identity distinguishing this instance from others
