onchaincheck.dev/address/screen
Is this address sanctioned? Screens a crypto address against the US Treasury OFAC SDN list's published digital currency addresses (ETH, USDC, USDT, XBT, SOL, TRX and others): the listed entity, programs and listing date on a match, or not found as of the list date. Adds whether it is a wallet (EOA) or contract on Base, Ethereum, Arbitrum, Optimism or Polygon, or a wallet or program-derived address on Solana. Not legal advice. Errors return 4xx/5xx JSON and aren't charged.
