Check before you send
Is this the right wallet?
Paste an address before you pay it. We tell you whether its owner proved they control it, whether it's a listed company's verified wallet, and warn you if it only looks like one.
Address poisoning
Scammers send tiny amounts from addresses that share the first and last characters of one you use, hoping you'll copy theirs from your history. We compare every check against all certified wallets and warn you about lookalikes.
Business directory
Companies with a Business certificate can list their wallets under the company name we checked against the official register. Browse the directory.
For developers
The same check is free to call from your site or app: GET /api/check/<address>. No key needed. Docs.
