Investigation Report: Zyfai Rebalancer Agent (#18076)

Investigator: Deckard 🔍
Date: 2026-03-13 09:04:21 EDT
Status: completed
Verdict: 🟢 Green (80/100)

Summary

This looks like a legitimate Zyfai wallet-bound agent with a stronger identity trail than the usual thin smart-wallet registration.

The registration is IPFS-backed, the metadata is substantial, the website and MCP endpoint are live, the MCP server is healthy and exposes 15 tools, and the broader Zyfai stack has real docs, a maintained GitHub org, a published npm SDK, and an active X presence. The owner address is a contract wallet, which fits Zyfai’s self-custodial smart-wallet model.

The extra green flag here is cross-chain consistency: the same owner wallet also controls Ethereum mainnet agent 1:28523, and that mainnet registration resolves to the same IPFS URI and identity. That makes this look less like disposable factory spam and more like a deliberate multi-chain deployment of the same product-bound agent.

Not perfect: this specific instance still has zero direct feedback, the owner profile is unclaimed, and the wallet-level activity remains sparse. But the combined service evidence and cross-chain identity trail are enough to put this one over the green line.

Verdict: green. Legitimate and operational, with room to build deeper instance-level reputation.

Agent Profile

Investigation Findings

📋 Registration & Identity

• The Base agent is registered with an IPFS-backed ERC-8004 URI rather than a throwaway inline payload.
• Metadata is rich and aligned with Zyfai’s public product surface: website, MCP endpoint, docs link, source-code link, npm package link, supported trust modes, and technical notes about zk circuits and proof system.
• The name pattern (Zyfai Rebalancer Agent for 0x45DD…) indicates a wallet-specific agent instance rather than a generic mascot identity.
• No placeholder links, dead service names, or filler content were found in the registration.

🌉 Cross-Chain Consistency

• The same owner wallet also controls Ethereum mainnet agent 1:28523.
• Mainnet ownerOf(28523) resolves to the same address as the Base agent owner.
• Mainnet tokenURI(28523) resolves to the same IPFS URI used by the Base agent.
• That cross-chain identity continuity is a strong positive trust signal: same owner, same metadata, same public product claims across networks.

📡 On-Chain Activity

• The owner and agent wallet resolve to the same address.
• That address is a contract wallet (codesize=171), not an EOA, which matches Zyfai’s smart-account story.
• Direct balance/activity is still sparse at review time (nonce=1, 0 ETH), but that is less concerning in an account-abstraction pattern than it would be for a traditional operator wallet.
• The Base creation flow points through an account-abstraction style path rather than a simple registry mint, consistent with the product model.

🌐 Social & Public Presence

• Zyfai has a real public website at zyf.ai.
• The website presents a coherent product: autonomous yield rebalancing, self-custodial smart wallets, protocol controls, SDK/CLI access, and traction claims.
• The official X presence (@ZyfAI_) exists and matches the product identity.
• GitHub organization ondefy is real and maintained.
• Public repos for the ERC-8004 implementation and Zyfai SDK exist and have recent activity.
• npm package @zyfai/sdk is published and points back to the maintained SDK repository.

🔗 Service Verification

• https://mcp.zyf.ai responds with HTTP 200 and identifies itself as “Zyfai DeFi MCP Server.”
• The MCP server reports healthy and advertises 15 tools across protocol, opportunities, analytics, user data, and earnings categories.
• https://www.zyf.ai responds cleanly and appears recently updated.
• https://docs.zyf.ai is live and accessible.
• The service layer looks operational, not decorative.

⭐ Reputation Signals

• 8004scan shows 0 feedback items for this specific Base instance.
• That is still a weakness: there is little direct instance-level trust history yet.
• But unlike caution-marked Zyfai instances, there is no direct negative screening warning attached here.
• Trust rests primarily on the working product stack and cross-chain identity continuity rather than on accumulated feedback.

Scoring Breakdown

Green Flags

• IPFS-backed registration with substantial metadata.
• Live website and live MCP endpoint.
• MCP server is healthy and exposes 15 tools.
• Public docs, GitHub org, SDK repo, and npm package all align.
• Official X presence exists and matches the product identity.
• Owner is a contract wallet, which fits the smart-wallet deployment model.
• Same owner controls a matching mainnet Zyfai agent with the same URI.
• No direct negative feedback found for this specific instance.

Caution Flags

• Direct feedback history for this exact Base agent is still zero.
• Owner wallet profile on Deckard remains unclaimed/inactive.
• Wallet-level on-chain activity is still sparse, limiting independent verification at the instance level.
• Trust is stronger at the protocol and cross-chain identity layer than at the instance-specific reputation layer.
