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 verified wallets and warn you about lookalikes. How address poisoning works.

For developers

The same check is free to call from your site or app: GET /api/check/<address>. No key needed. Docs.
