The cryptocurrency industry has been steadily growing over the past few years. Despite frequent price fluctuations, the cumulative market capitalization of digital coins reached $237.1 billion in 2019, up from $128.78 in 2018. And although the rise of virtual currencies is impressive, it’s hindered by a number of security concerns.

For one, criminals have stolen digital coins worth billions of dollars in the last year alone. You might, however, dismiss such concerns and consider your private keys as practically unhackable. And although that’s true, hackers won’t brute force your codes but will rather steal them by penetrating exchange platforms and hot and cold wallets that generate, store, and use private keys. And all they need to wreak havoc is for their targets to go online.

The NGRAVE ZERO works completely offline, eliminating remote attack vectors

Enter ZERO, NGRAVE’s proprietary hardware wallet that successfully solves this conundrum. This touch-screen, pocket-size device has no Bluetooth, Wi-Fi, 4G, NFC, or any other type of network capability. Its USB-C port is only used for wall charging and firmware updates, and is protected by a secure operating system that is EAL7 certified, which is the highest level of security assurance and protection in the world.

On the mechanical side, the ZERO is made of a high-end customized alloy of different metals for optimized protection, weight, moldability and premium feel. The interior electronics have been built from scratch with the world leading research and development hub for nanoelectronics, imec, and also feature a built-in camera, light- and fingerprint sensor.

A revamped and upgraded offline key generation process

The NGRAVE ZERO is fully backward compatible with existing key formats such as 12-,18-, and 24-word mnemonic phrases, including the generation and import of these keys. But with the end user’s security in mind, the NGRAVE team has also fully revamped the actual key generation process to eliminate these residual risks, resulting in what it calls the “NGRAVE Perfect Key”. This key is the 64-character hexadecimal equivalent of the 256-bit master seed, or 24-word mnemonic seed phrase. This new format allows for a gamified interaction process on the ZERO between the user and the key, so that even the manufacturer, in this case NGRAVE, won’t have the slightest clue of what the user’s final key might be. The hexadecimal format also allows for a huge upgrade in security of the key backup, for which NGRAVE built its own secure, encrypted, everlasting backup solution known as the GRAPHENE.

NGRAVE’s key generation process is done completely offline and relies both on the entropy generated by the chip as well as environmental randomness such as biometrics and ambient light. Finally, the user can interact with the key generation process, ensuring he/she is the only one to know the key.

QR-based communication with the outside world

Throughout the entire process, the QR codes never reveal nor contain data on your private keys. Meanwhile, other hardware wallets rely on USB or Bluetooth to sync accounts or sign transactions. These communication channels have proven to be vulnerable and pose a risk to the security of your private keys.

Syncing accounts, as well as receiving and sending transactions, happens in a completely offline manner, taking online hackers out of the equation. The ZERO and the “LIQUID” mobile app communicate through QR codes that never contain any information on the private keys.

A powerful anti-tampering framework

Furthermore, the ZERO is designed to detect any intrusions and wipe itself if under attack, known as tamper responsiveness. And finally, NGRAVE introduces an entirely new layer: tamper resolution. Even if an attacker would accomplish a perfect tampering throughout the previous layers, the initial key generation process occurs through several interactions with the end user, removing any effect of the tampering.
