DEFAI ComplianceOS

DEFAI ComplianceOS is a cross-border crypto-asset compliance reasoning layer. It returns pre-transaction PASS / FLAG / BLOCK decisions across VARA (UAE), MAS (Singapore), FCA (UK), and FATF in a single API call, with verbatim regulatory citations grounded in the source rulebook PDFs. Existing tools (Chainalysis, Elliptic, TRM Labs) flag risky wallets and patterns. None of them tell you why, in the language of the regulator who'd actually audit you. ComplianceOS does. Built on Claude Opus 4.7 with pgvector RAG over the actual VARA, MAS, FCA, and FATF PDFs, plus a content-hashed audit trail (SHA-256 prompt hash + regulatory snapshot) so any decision is reconstructable months later. OFAC SDN wallet screening runs deterministically before Claude is called. Status: 5-day proof-of-concept built for the Anthropic Built with Opus 4.7 Hackathon. Chapter 1 of three — the compliance-reasoning foundation. Chapters 2 (agent identity via ERC-8004 + x402) and 3 (B2B payment rails on stablecoin).
