Simple Cold Storage Wallet for Bitcoin

KeepKey: Bitcoin Hardware Wallet

KeepKey is a USB device that stores and secures your bitcoins. When you entrust KeepKey with your money, each and every bitcoin transaction you make must be reviewed and approved via its OLED display and confirmation button. It now becomes nearly impossible for virtual attackers like malware or viruses to steal your valuable bitcoins.

How it Works
KeepKey works with the bitcoin wallet software on your computer by taking over the management of private key generation, private key storage, and transaction signing.

Initialization and Backup
KeepKey generates your Bitcoin private key using its hardware-based random number generator, combined with randomness provided by your computer. Once your private key is generated, you are given the one-time opportunity to write down a backup of your KeepKey in the form of a twelve-word recovery sentence.

Secure Storage: Your private key is stored securely on your KeepKey, never leaving the device. Your KeepKey is PIN-protected, which renders it useless even if it falls into the wrong hands.

Transacting: KeepKey's large display gives clarity to every bitcoin leaving the device. Each transaction must be manually approved using KeepKey's confirmation button.

Recover: If your KeepKey is lost or stolen, you can safely recover your device without compromising its private keys.
