How this service works

Screen one address (EVM, Bitcoin, Tron, Solana, Polkadot, Cosmos or WAX as wax:account) against the OFAC SDN list, Tether/Circle freezes (EVM, Tron, Solana) and public C3 reports. Returns action BLOCK (OFAC SDN match), REVIEW (reported or frozen; current freeze = HIGH) or ALLOW_NO_REPORTS, riskScore, riskLevel, sanctions, freezes, reports, related domains, co-occurring addresses. NONE_REPORTED means nothing found, not that it is safe. Sanctions: official OFAC SDN list only; not legal advice.

Output

Returns a simple risk verdict: 'caution' if the address appears in the C3 community fraud reports or is on the OFAC sanctions list, or 'clean' if no issues are found.
