anchored·PJk9dy…vJtdSummary
YO Protocol (yo.xyz), operated by YO Labs, is a San Francisco-based multi-chain DeFi yield optimization protocol founded by former Uber and Amazon executives and backed by Paradigm, Coinbase Ventures, and Foundation Capital with $24 million in total funding. Independent security research published in September 2025 identified significant centralization risks, MEV attack vectors, and EIP-4626 compliance gaps that existing audits had not fully addressed. No hacks, exploits, or regulatory actions have been publicly confirmed against the protocol; a claimed ZachXBT flag has not been corroborated by any findable public source as of May 2026.
