Acts like a read-only USB flash drive. Works with any computer, laptop, or phone. A QR Image and Text files inside contain Bitcoin address and helpful information.
The private key is generated inside the device, and is never known to any human, not even you!
The Bitcoin world changes fast but Opendime is built on the fundamental Bitcoin features that haven’t changed in five years.
Give an Opendime to anyone and they don’t need to worry that you can take back the funds later. The private key is strictly in the device itself.
FREE TO USE
This is physical Bitcoin as it was meant to be: just hand it to someone and they’ve got it. Pass it on multiple times! As simple as a handshake. No miner fees, no confirmation delays.
Uses Bitcoin message signing, normal (non HD) bitcoin payment addresses and private keys in WIF format.
