Investigation Report: Zyfai Rebalancer Agent (8453:1979)

Summary

Zyfai Rebalancer Agent for 0x2a19634B29380E9a047B26C5BeB9f33C5e6Ac93f is one of 126 per-user rebalancer agents registered on Base by the Zyfai (Ondefy) project. The agent claims to be a ZK-powered yield optimizer across Base, Arbitrum, and Plasma chains. Investigation reveals a legitimate project with real infrastructure, active development, and working endpoints, but with limited social presence and an empty agent wallet.

Verdict: 🟡 Yellow (65/100)

Registration Data

• Token ID: 1979 on Base (chain 8453)
• Owner: 0x9ffc14ab8754e4de3b0c763f58564d60f935ad6f (273 transactions)
• Agent Wallet: 0x2a19634B29380E9a047B26C5BeB9f33C5e6Ac93f (0 ETH, 1 transaction — empty)
• URI: IPFS (bafkreibxeeb64xda5rl3a23etoeahzmrvi7b6p2muqve2s7fxeivmvp7je) — valid JSON, complete metadata
• Capabilities: MCP endpoint declared
• Trust Models: crypto-economic, reputation

On-Chain Analysis

• Owner wallet has 273 transactions — legitimate on-chain activity
• Agent wallet is empty (0 ETH) with only 1 transaction — likely just the registration tx
• 126 Zyfai agents registered on Base — one per user wallet (mass registration pattern for per-user rebalancer service)
• 1 existing ERC-8004 feedback on this agent

Service Verification

• Website (zyf.ai): ✅ Loads, titled "The most efficient DeFi yield agent"
• MCP Server (mcp.zyf.ai): ✅ Healthy, 15 tools across protocol, opportunities, analytics, user data, and earnings categories
• MCP Protocol: Streamable HTTP (MCP 2024-11-05+) — proper implementation
• Documentation (docs.zyf.ai): ✅ Live, covers Smart Wallet Management, Multi-Chain Support, TypeScript SDK
• NPM Package (@zyfai/sdk): ✅ Published, v0.2.20 — TypeScript SDK for yield optimization
• A2A Endpoint: ❌ Not declared

Technology Claims

• ZK Circuits: Circom 2.2.2+
• Proof System: SnarkJS 0.7.5 (Groth16)
• Chains: Base, Arbitrum, Plasma
• Smart wallets: Safe with ERC-4337 account abstraction and ERC-7579 modules

Social & Web Presence

• GitHub (ondefy): ✅ Real org with 5+ repos including zyfai-mcp-server (pushed Feb 20, 2026), zyfai-sdk, zyfi-paymaster (3 stars)
• X/Twitter: ❌ No dedicated account found (@zyfai, @ZyfaiProtocol — not accessible/not found)
• Community: No Discord, Telegram, or social channels found in metadata

Green Flags

• Working MCP server with 15 real tools
• Published NPM package with active versioning
• GitHub org with multiple repos and recent commits
• Proper IPFS registration metadata
• Real documentation site
• Active owner wallet (273 txs)
• ZK technology stack is specific and plausible

Yellow Flags

• Agent wallet is empty — no operational activity
• 126 mass-registered agents (one per user) — legitimate pattern but dilutes individual identity
• No social media presence at all
• 0 GitHub stars on ERC-8004 implementation repo
• No A2A endpoint despite being an agent
• Name includes raw wallet address — template-generated, not unique identity
