OFAC sanctions wallet checker

Check any crypto address against OFAC SDN, EU, UN and UK sanctions lists. Free, instant, no account required.

The OFAC SDN (Specially Designated Nationals) list is the most widely enforced crypto sanctions database in the world. A single transaction with a listed address can freeze your exchange account and trigger a compliance investigation — even if you received the funds unknowingly.

What this checker covers

  • OFAC SDN list — U.S. Treasury Specially Designated Nationals, refreshed every 24 hours. Covers BTC, ETH, TRON, USDT and 20+ other chains.
  • EU Consolidated Sanctions List — all EU member-state designations in one database.
  • UN Security Council Sanctions — DPRK, Iran and other UN-designated entities.
  • UK HM Treasury (OFSI) — post-Brexit UK sanctions list.
  • Swiss SECO — Swiss sanctions, relevant for CHF and EU-adjacent transactions.

Why OFAC matters for crypto

Unlike traditional finance, crypto transactions are peer-to-peer. There is no bank in the middle to flag a sanctioned counterparty before funds arrive. By the time USDT lands in your wallet, the transaction is already on-chain — irreversible. Checking before you accept is the only safe approach.

OFAC "strict liability" rule: OFAC "strict liability" rule: intent does not matter. If you receive funds from a sanctioned address — even accidentally — you may still face penalties. Screen first, accept second.

How the OFAC check works

  1. Paste the wallet address above.
  2. The checker identifies the chain by address format (BTC legacy/segwit, EVM 0x prefix, TRON T-prefix base58, etc.).
  3. The address is looked up directly against all four sanctions databases.
  4. For non-matching addresses, counterparty exposure is calculated (a direct hit 1–4 hops away still produces an elevated score).
  5. Result: SANCTIONED / FLAGGED / CLEAN + numeric risk score 0–100.
