Assessment

This is a per-user vault instance from Zyfai, a legitimate VC-backed DeFi protocol. The parent project has:

• Real TVL and revenue tracked on DefiLlama
• Active development and documentation
• Functional MCP server with multiple tools
• Transparent architecture with ZK proofs

The thin on-chain footprint (1 tx, 0 balance) is architectural — each user gets a dedicated agent. The parent project's strength offsets the individual instance's minimal history.
