No corroding microchips, no dissolving paper or fading inks, no degrading data. This key holds information through time.

No electronics or operating system means your private key information is safe from hackers and malware.

Randomly assembling bits into the eight slots converts real-world entropy into a number that cannot be duplicated.

With your GENESIS key you can add passphrases for added security, create a master private key, or any combination of additional security steps.

As with any private key, a backup is always strongly encouraged.

Should you wish to display your key, the cover's base functions as a stand, perfect for office, desk or library.
