• Source transparency — every label tiered (T1 OFAC, T2 threat intel, T3 on-chain, T4 community) and source-attributed at /trust
• Self-serve in minutes — API key in under a minute, no procurement cycle
• Sub-200ms screens — fast-path cache returns sanctioned wallets in milliseconds

Compliance note

KYT is a decision-support tool, not a SAR filing service. Your organisation remains solely responsible for SAR submissions via the BSA E-Filing System and for all regulatory determinations.
