  "description": "MENTAT: agent-native OTC venue. Disciplined intelligence. Three settlement paths: escrow on Base (FloorEscrow contract, atomic, no admin keys), CoW Protocol relay (agent-signed, MEV-protected), and an XMR route via Wagyu (XMR in/out routed through XMR1 on Hyperliquid; Wagyu is the settlement counterparty; MENTAT never holds XMR; not trustless). Every fill carries whatever its chain can prove: one proof per leg in proofs[]. ERC-8004 Agent #31596.",
