NGRAVE is a premium hardware wallet designed to deliver maximum security while being exceptionally easy to use. It is the ultimate choice for crypto enthusiasts who prioritize safety and usability in storing their digital assets.
NGRAVE's product suite is comprised of ZERO, the coldest wallet, GRAPHENE, the ultimate backup, and LIQUID, your real-time connection to the blockchain.
ZERO
The most secure and easy-to-use wallet that is truly offline:
- A hardware device able to generate and store private keys, and sign transactions using these keys offline.
- The most secure wallet in the financial industry (EAL7 certification).
- Built from scratch in close collaboration with world leaders in hardware security, chip manufacturing, and industrial cryptography.
- All possible online attack vectors are removed (the device is ‘air-gapped’): ZERO has no Wi-Fi, cellular, Bluetooth, NFC, or other type of connection for wireless communication.
- The device can communicate in a completely offline manner through one-way QR codes.
- The key generation process not only uses ‘true randomness’ from the secure internal chip, but also incorporates external factors (e.g., the user’s fingerprint and interaction) for maximum entropy.
- Integrated with Metamask and Rabby Wallet - users can use dApps, stake, swap, and more on MetaMask with private keys secured offline on NGRAVE ZERO.
GRAPHENE
A unique physical encrypted backup made of 2 plates of high-quality stainless steel:
- A physical backup for the key generated by ZERO, which consists of 64 hexadecimal characters (equivalent to a 256-bit master seed or a 24-word mnemonic phrase).
- The backup consists of two separate, everlasting stainless-steel plates. The top plate has 64 columns with 16 holes each, where each of the 16 holes is labeled with a different hexadecimal character (0-9 and A-F).
- The plates are highly durable and resistant to extreme heat (e.g., a house fire up to 1660°C), water spills, corrosion, shocks, etc.
LIQUID
App that provides a real-time portfolio overview without exposing private keys:
- Mobile app built to facilitate interactions between the ZERO cold wallet and the internet (i.e., hot wallets, exchanges, or directly to the blockchain).
- Visualize ETH NFTs
- Buy crypto
- Swap crypto
- Store multiple ZERO or Passphrase wallets
