Highest Certified Financial product
The only crypto hardware wallet with EAL7 certification.
Air-gapped
ZERO is connectionless. It does not rely on USB, WiFi, Bluetooth, NFC, or 4G to sign transactions. All communication happens via transparent QR codes.
Custom OS
ZERO’s Operating System (OS) was developed from scratch by our security experts. While some hardware wallets rely on mobile phone operating systems, NGRAVE removes any associated vulnerabilities with its own OS.
Passphrase and hidden wallets
This security feature extends your Perfect Key or seed phrase. Adding a passphrase creates a new hidden wallet with new coins and addresses. They are not stored on ZERO, and you can create as many as you want.
Multi-layer tamper protection
You can’t open ZERO without damaging it or leaving traces, letting you verify if it got manipulated during shipping. And if your ZERO gets stolen after setup, sensors inside wipe the device if opened.
Biometric Authentication and Key Generation

A revolution in
Key generation
We give you all the tools to create the safest key to truly own your crypto. Not your keys, not your crypto.
For your eyes only
The NGRAVE Perfect Key is the equivalent of a traditional 24-word seed phrase in a 64-character hexadecimal format. ZERO uses your biometrics and allows you to shuffle parts of your key to generate the Perfect Key.

The NGRAVE Perfect Key
The NGRAVE Perfect Key is convertible into a traditional 24-word seed phrase. You can easily visualise it in your ZERO and are always free to import your seed into another wallet.

Never lose your keys again
Your backup should be easy to understand for you and an enigma for anyone else. The hexadecimal format of your Perfect Key allows you to back it up on GRAPHENE, the first encrypted and recoverable stainless steel backup.

Questions?
- Can I buy NGRAVE products via resellers such as Amazon?
You can only order your ZERO in the NGRAVE webshop or Amazon US (COMBO). At this moment we don't work with any resellers.
If another party than NGRAVE offers you to buy a ZERO do not give them your money. In case of doubt, always consult with us via support@ngrave.io. - Can I convert the NGRAVE "Perfect Key" to 24 words?
Last updated December 16, 2023 19:45
Yes. The hexadecimal “Perfect Key” can easily be converted into the 24-words version and vice versa. Both are alternative representations of a 256-bit private key.
On the ZERO, you can easily see both versions. Go to Settings → Display secret key, enter your PIN code and then select Mnemonic or NGRAVE wallet.
If you need to do the conversion yourself, you can use this tool: https://iancoleman.io/bip39/
NEVER USE THIS TOOL ONLINE with your key!
There is always a risk that your communication is intercepted or the website logs your private key data, which might result in your funds being stolen. You should always download this tool and run it on your own computer. Best practice is that your backup is never entered on a computer. So only use this tool when you need to. We recommend to move your funds to a new wallet afterwards to preserve optimal security.
How can you a convert between formats?
In short, using the Coleman tool boils down to this:
Download the tool to your computer and open it.
To convert from mnemonic words to hexadecimal format, fill in the field 'BIP39 Mnemonic' and tick 'Show entropy details'.
The hexadecimal format is in the field 'Entropy'.To convert from hexadecimal format to mnemonic words, tick 'Show entropy details' first and only then fill in the field 'Entropy' . The 24 words format is in the field 'BIP39 Mnemonic'.
