NGRAVE annihilates the need for paper wallets & traditional metal back-ups, introducing the coldest back-up available.
The NGRAVE GRAPHENE is a cryptographic puzzle made of two fire-, water-, buried-, & shock-proof everlasting stainless steel plates. If an attacker gets his hands on one of the plates, he still has zero information about the actual secret key. Therefore, it is recommended to keep each plate at a different location.
NGRAVE offers the first recoverable key back-up solution. Finally an answer to losing your back-up.
The Coldest Back-up
The ZERO is the most secure hardware wallet ever made, and
the corner stone of NGRAVE’s impenetrable security ecosystem.
Conceptualized and built from scratch in close collaboration with
world leading institutes in chip manufacturing, applied
cryptography, and hardware security, the ZERO comes at an
unparalleled level of inherent anti-tampering.
The ZERO is completely offline, from secret key generation to transaction signing, keeping your holdings away from any online attack vector.
NGRAVE provides a mobile app to directly sync all the generated accounts from the ZERO. That way, the user can easily consult his real-time balances or ask to receive a transaction.
Communication between the ZERO and the app occurs through QR-codes. This way, the app never has access to the secret keys on the ZERO.
Hence, the secret keys are never exposed to any online attack vector. Not even when signing transactions.
Last-mile Connection to the Blockchain
"The internet is the crypto equivalent of Pandora’s Box.
As soon as you have an online connection, hackers can try to steal your funds"
Offline is the New Online
— Ruben Merre, CEO NGRAVE @ Stanford University (2019) —
A Wall That Can't Be Breached
at the safe side of the wall
NGRAVE has pulled up an impenetrable wall between the online and offline realm
Cryptographic secrets are kept offline at all times and are never exposed to an online connection. They never “cross the wall”
Everything that is sensitive is done offline, from wallet creation to signing transactions
USB & Network-Free
Airgapped for security
USB cables are not only a hassle, they also permit data to and from your device, so you ultimately never know what info is coming in or going out
NGRAVE has airgapped the ZERO, making it a stand-alone device that doesn’t rely on networks (4G, wifi, bluetooth, etc.) or USB cables
No network = no digital attack surface
One-Way QR Communication
The safest way to broadcast transactions
Offline generated accounts are exported by scanning a QR code with the Liquid app
Transactions are initiated and converted into a QR-code in the app. The ZERO scans the signature request QR-code with its built-in camera
The ZERO signs transactions offline, without exposing the secret cryptographic key(s). A signature validation QR code is generated, and can be scanned by the app to broadcast the validated transaction to the blockchain
