About Opendime
The Opendime is a disposable, single-use Bitcoin hardware wallet — essentially a physical Bitcoin bearer instrument. It generates a private key internally that cannot be extracted until the device is physically 'popped' (broken). Before opening, anyone can verify the balance via the public key. Opendimes are used for physical Bitcoin transactions, gifts, and as a secure bearer instrument.
