Meet our Ultra Secure, Multi-layered Digital Asset Ecosystem
One seamless, worry-free environment
An all-in-one solution for all your needs
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 on nano-electronics, 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
In close collaboration with true security experts, NGRAVE has developed custom firmware to assure both superior security and ease-of-use. A great example is NGRAVE’s revolutionary wallet generation process including a.o. biometric data and security-enhancing user interaction flows. NGRAVE will also open source its firmware for community review.
Optimized for Security & Ease-of-use
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
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.
NGRAVE brings together a super secure hardware wallet, an everlasting encrypted back-up solution, and a mobile application for blockchain transactions
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
The Most Advanced Key Generation Process in the World
State-of-the-Art TRNG Chip
Create a computationally unique, unbreakable, & unpredictable secret key with a strong True Random Number Generation (TRNG) process
Your fingerprint is included in the key generation process to create your own personalised key
Photon measurements of ambient light are one of the best enhancers of the randomness and strength of your secret key
User Interaction, Offline
As a user, you interact with the offline key generation process, making you the only one who has ever seen the secret key
A computationally unbreakable & unique key, generated offline, only ever seen by you and you alone
"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"
