Example prompts after install

Screen wallet 0x722122dF12D4e14e13Ac3b6895a86e84145b6967 — is it sanctioned?

Open a case for the Tornado Cash address I just screened.

Generate a SAR draft for case <id> and email me a summary of what to include.

What labels do we have on 0x... — quick check, no full screen.

Why KYT over alternatives

  • Published pricing — no "contact sales" — Free $0, Starter $49/mo (500 screenings), Pro $199/mo (3,000 screenings)
  • 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

Compare honestly vs TRM Labs + Chainalysis Reactor Lite: https://kyt.infinihash.com/kyt/compare

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.
