GRAPHENE
The Ultimate Backup
The first encrypted and recoverable crypto backup. Never lose your keys.
Two plates. One punch pen.
Back up the Perfect Key you generated on ZERO. Punch the characters through the upper plate into the lower plate with the punch pen. Then, you can separate and hide the plates in different locations.
An enigma to everyone but you
If someone finds one of your plates, they will not be able to read your Perfect Key. Only the combination of your upper and lower plate will reveal your key.
A recoverable backup
If you lose your upper plate, we can send you a new one if you provide your Ultimate Recovery Code. As NGRAVE has no information on your lower plate, your Perfect Key remains safe.
