How this service works
OFAC SDN sanctions screening for a crypto address or a person/company name. Covers all 963 digital-currency addresses OFAC lists across 19 chains (BTC, ETH, TRX, USDT, SOL, XMR and more) plus 19k sanctioned entities and their aliases. Straight from the US Treasury's own list, refreshed daily.
Output
Returns a JSON object containing the queried address, the sanctions list checked (e.g. OFAC SDN), a boolean sanctioned flag, the match type, match count, and an array of matched entities with their names, associated sanction programs, SDN entity type, and linked crypto addresses across chains.
Example use cases
Pre-transfer compliance check
“Before I send USDC to 0x3a8F2d6C9b1E4F0A7D5C2B8E1F3A9D6C4B2E8F1A, can you screen that wallet against the OFAC SDN list and tell me if it's safe to transact with?”
DeFi protocol counterparty screening
“We're integrating a new liquidity provider at address 0x4e83362442b8d1bec281594cea3050c8eb01311c — run a sanctions check on it against OFAC to make sure we're not violating compliance rules.”
Post-transaction sanctions audit
“I need to audit a list of addresses that interacted with our protocol — start with 0x1da5821544e25c636c1417ba96ade4cf6d2f9b5a and tell me if it matches any sanctioned entity on the SDN list, including which programs it's tied to.”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/sanctionsWhen to prefer
Use this endpoint when you need real-time OFAC SDN sanctions screening for a specific crypto wallet address as part of a DeFi transaction compliance workflow, AML due diligence, or counterparty risk check. Prefer this over generic blockchain explorers when you need structured match data including program names, SDN type, and publication date in a single API call.
Side effects
- Address not found on any list returns sanctioned=false with empty matches array
- Malformed address input may return a validation error
- Network or service downtime may return 5xx errors
- Stale list data if list_published date is outdated
- Rate limiting or payment failure via x402 micropayment protocol
