Catch a bad address before you send
A cryptocurrency transaction to a mistyped address is usually irreversible, and the funds are gone. This validator checks whether an Ethereum or Bitcoin address is well-formed before you rely on it, so a transposed character or a truncated paste is caught at the point where it can still be fixed.
Validation is about format and checksum, not ownership
The check confirms the address has the right structure and passes its built-in checksum. Both Ethereum and Bitcoin addresses include a checksum specifically so that a typo produces an address that fails validation rather than a valid-looking address for the wrong destination. Passing the check means the address is properly formed; it does not and cannot tell you who owns it or whether it is the address you intended.
A cheap safety step
Validating an address takes a second and prevents a class of costly, irreversible mistakes. Use it whenever you paste an address from an untrusted source, retype one, or want to confirm a copy did not truncate. The validation runs entirely in your browser, so the address is not sent anywhere.

Frequently Asked Questions
What does the validator check?
That the address is well-formed for its network and passes its checksum, so a typo or truncation is caught. It confirms format, not ownership.
Does a valid address mean it is the right one?
No. Validation confirms the address is correctly structured, not that it belongs to the person you intend to pay. Always confirm the address itself with the recipient.
How does a checksum catch typos?
Both Ethereum and Bitcoin addresses embed a checksum, so a single mistyped character almost always breaks it, turning a typo into an address that fails validation rather than a valid one for the wrong place.
Which networks are supported?
Ethereum and Bitcoin addresses, selectable before you validate.
Is the address uploaded?
No. The validation runs entirely in your browser.
