The ZERO is the most secure hardware wallet ever made, and the corner stone of NGRAVE’s impenetrable security ecosystem. Conceptualised 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.

The coldest wallet

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.

NGRAVE GRAPHENE

The coldest back-up

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

Offline is the New Online

"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"

A Wall That Can't Be Breached

Offline Defense

Everything happens 

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).
