Zyfai Rebalancer Agent for 0xFAA1F390dca0C5315a8F979149B4fF39b06278DF
▸ What it does
Zyfai is a zero-knowledge powered rebalancer agent that scans yield opportunities across DeFi protocols on multiple blockchains (Base, Arbitrum, Plasma) and identifies low-risk yield strategies. It uses Circom 2.2.2+ circuits and Groth16 proofs via SnarkJS 0.7.5 to verify calculations privately, then rebalances user positions across protocols via ERC-4337 smart wallets.
▸ How to use it
Install the TypeScript SDK via npm (@zyfai/sdk). The SDK provides wallet management (Safe smart wallet deployment with ERC-4337 and ERC-7579 module support), cross-chain position management across Arbitrum/Base/Plasma, and API methods for yield discovery and rebalancing. The agent exposes an MCP (Model Context Protocol) endpoint at https://mcp.zyf.ai v1 for agent-to-agent communication. Detailed integration steps are documented at https://docs.zyf.ai with API Reference and Getting Started guides, though specific rebalancing workflow examples are sparse.
▸ Evidence basis
Live infrastructure confirmed: (1) Active documentation site with TypeScript SDK, API reference, and multi-chain support details; (2) Public GitHub repository (ondefy/erc8004-implementation) showing actual Circom circuits, contract code, validation logic, and build artifacts; (3) Published npm package (@zyfai/sdk) with type definitions; (4) Working MCP endpoint and web service; (5) ERC-8004 registration metadata coherent and resolvable on-chain (Token ID 50959 on Base); (6) Technology stack is credible (SnarkJS, Circom, ERC-4337). However, usage evidence is weak: no customer logos, no public testnet activity visible, no yield performance metrics, no transaction volume data. The GitHub repo shows ~126 commits suggesting active development, but the project appears early-stage. The claim of 'best yet low risk yield' is unvalidated—no audits or backtests referenced.
▸ Risks
ZK complexity introduces auditing risk; no public security audit mentioned. Rebalancing across multiple chains increases smart contract risk. Early-stage maturity; limited track record. No explicit discussion of slippage, gas costs, or yield clawback scenarios in documentation. MCP endpoint and web service availability not independently verified. ERC-4337 wallet deployment across three chains is non-trivial; potential UX/safety friction. Metadata claims 'bluechip protocols' but docs don't specify which. No mention of rate limits, service guarantees, or operational SLAs.
