Screen one blockchain address (EVM, Bitcoin, Tron or Solana) against the officia
Screen one blockchain address (EVM, Bitcoin, Tron or Solana) against the official OFAC SDN list, Tether/Circle stablecoin freezes and public C3 fraud reports. Returns action BLOCK (OFAC SDN match), REVIEW (frozen or reported) or ALLOW_NO_REPORTS, plus riskScore, riskLevel, sanctions, frozen/freezes, reports, related domains and co-occurring addresses. NONE_REPORTED means nothing was found, not that the address is safe. Sanctions: official OFAC SDN list only; not legal advice.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
