Graphene

The Ultimate Backup

GRAPHENE is the ultimate backup for your Perfect Key.

It is made of high quality stainless steel that withstands extreme temperatures, water, corrosion and shocks.

Your ultimate backup

Everlasting
Resilient against the forces of nature
Forget paper wallets. Nothing so resilient as high quality stainless steel. Temperatures up to 1660°C (3000°F) mean nothing to GRAPHENE. Neither do water floods, corrosion, shocks, and well, practically anything else.

Additional security
Split your backup in two undecipherable parts
We take your safety so seriously that we went for the highest security certification in the world. ZERO is the only financial product to ever obtain it.

Recoverable
A backup of your backup without third party risk
We have added an “Ultimate Recovery Code” just in case you would lose your upper plate. Each upper plate configuration is unique and personal, and can be recovered in case of loss. As NGRAVE (or any other third party) has no information on your lower plate, your secret key remains safe.

Back up your backup
Additional Lower Plate
Make extra backups by punching your key into multiple lower plates. The upper plate can be recovered by NGRAVE but not the lower plate. We recommend making at least one additional backup.

How it works
Safely backup your crypto in 3 easy steps
  • Step 1
    step-1-generate
    Generate
    Create your NGRAVE Perfect Key on ZERO. This key has a 64 character hexadecimal format, meaning that each individual character value ranges from 0-9 and A-F.
  • Step 2
    step-2-punch
    Punch
    Bring your upper and lower plate together and use the NGRAVE punch pen to make a hole in each of the 64 columns. Every column represents one character of the secret key, and when both plates are perfectly aligned on top of each other, you can read of your key.
  • Step 3
    step-3-split-hide
    Split & hide
    It is highly recommended to store and safeguard each plate separately if you want to benefit from the GRAPHENE's double security layer.
