OpenDime Bitcoin


SKU: OD-BTC Category:


Packed with Features

USB Drive

  • 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.

Ultra Secure

  • 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.

No Trust

  • 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.

Open Standards

  • Uses Bitcoin message signing, normal (non HD) bitcoin payment addresses and private keys in WIF format.

Based on Private Keys

  • Each Opendime holds one private key. It publishes the public key (payment address) to anyone and never reveals the key until “unsealed”.

Piggy-Bank Economics !?

  • Yes. It’s like a piggy-bank. You must destroy it to spend the funds. At first that seems expensive and wasteful, but it’s a key part of our security       model: you can trust a sealed Opendime, and it’s obvious when it’s been opened.

Instant and Off-Chain

  •   *Since we are putting private keys into a physical form you can trust, you can simply hand around Opendime units to move amounts around. There  are no pre-defined Bitcoin amounts with Opendime either.  Store as much or as little as needed.
