Wallet Safety Checks — address screen

Limited track record

How we rate this

Delivery health: unknown. Paid successes: 0. Paid failures: 0. Schema confidence: high.

Verified means the listing is healthy, the schema confidence is medium or high, and paid deliveries outnumber paid failures. Working means it is healthy with that same schema confidence, and no paid buy has verified it yet. Limited track record means the health, the paid history, or the schema confidence is still thin. Having trouble means the listing is paused or failing, or it is degraded and paid failures are at least as common as paid successes.

More

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.
