OFAC Crypto Wallet Sanctions Checker 🛡️

Screen any crypto wallet address against the official OFAC SDN sanctions list (U.S. Treasury) in real time. Returns whether the address is sanctioned, which blockchain, and the sanctioned entity behind it.

Built for exchanges, wallets, DeFi apps, payment processors, and compliance/KYT tools that must screen on-chain counterparties. Sending funds to (or from) an OFAC-sanctioned address can trigger civil penalties of US$250,000+ per violation — so this check is not optional, it's the law.

What it does

• Takes one or many wallet addresses.
• Matches them against the official OFAC SDN Advanced list (auto-downloaded from the U.S. Treasury, not a stale third-party copy).
• Returns for each: sanctioned (true/false), currency/chain, and the entity (e.g. Lazarus Group, Bank Markazi (Central Bank of Iran)).
• Auto-refreshes the list (cached, re-downloaded every N hours — OFAC updates several times a week).

Supported chains

BTC, ETH, TRX, XMR, USDT, USDC, LTC, XRP, SOL, BCH, BSV, ETC, ZEC, DASH, DOGE, BTG, XVG, ARB, BSC — every digital-currency address type OFAC publishes.

Input

{
  "addresses": [
    "TNiq9AXBp9EjUqhDhrwrfvAA8U3GUQZH81",
    "0x098B716B8Aaf21512996dC57EB0615e2383E2f96"
  ]
}

You can also pass a single "address": "...". Optional "refreshHours" (default 12) controls how often the OFAC list is re-downloaded.
