Sanctions Wallet
by Sanctions screening - crypto in Onchain & crypto
Is this blockchain address on the OFAC SDN list? Screens any address against every Digital Currency Address OFAC publishes (Bitcoin, Ethereum, Tron, USDT, USDC, Monero, Litecoin and more). A match names the sanctioned entity and its SDN id. A miss is reported as 'not on the lists checked, as of this date' and is never a clearance - the answer carries that caveat in the payload. Deterministic: a cached copy of the published list, no model in the path.
