NGRAVE Zero Review (2025): The Coldest Wallet You’ll Ever Own

If you're serious about securing your cryptocurrency, you’ve probably already heard about hardware wallets. Let’s face it: software wallets like Metamask may be convenient, but they’re far from the safest option. Being connected to the internet makes them vulnerable to potential hacks. That’s why cold wallets, which are kept offline, are a must for truly secure storage. However, even popular cold wallets like Ledger Nano and Trezor can have vulnerabilities. Enter the NGRAVE Zero, a cutting-edge hardware wallet that is touted as the most secure cryptocurrency storage solution available today.

In this review, we’ll explore how the NGRAVE Zero sets itself apart from the competition and why it might be the perfect solution for you.

What Makes Ngrave Zero So Secure?

Unlike other hardware wallets, the NGRAVE Zero wallet offers zero connectivity—it has no Wi-Fi, no Bluetooth, no USB connections, and no desktop application. It communicates with its mobile app Liquid purely through QR codes, ensuring that your private keys never come into contact with the online world.

1. Offline Private Key Generation

The device generates your private key entirely offline. This private key is never exposed to the internet, keeping it safe from any potential online attacks. With other wallets, even though they may be considered "cold," they still require a connection to your computer or the internet to execute transactions. With NGRAVE, you can rest easy knowing that your keys are staying completely offline.

2. Anti-Tamper Protection

NGRAVE Zero is designed with anti-tamper technology. If the wallet detects any attempt at a physical attack, it will automatically wipe itself, ensuring that your funds and keys remain secure. The wallet is even built in Belgium, which may give extra peace of mind to those wary of devices manufactured in China.

3. The NGRAVE Zero Hardware

The NGRAVE Zero is sleek and durable, featuring a touchscreen interface for smooth operation. While there’s only one mechanical button (the power button), everything else is handled through its responsive touchscreen. There’s also a camera and fingerprint scanner located on the back, which you’ll use during setup to ensure top-notch security.

4. The Graphene Backup

One of the standout features of the NGRAVE ecosystem is the Graphene Backup. This is a set of two steel plates designed to store your private key in case of emergency. The top plate is engraved with randomized characters, while the bottom plate contains your personal information. The idea is that if you lose your top plate, the company can provide a replacement (since the characters are randomly generated).

However, if you lose the bottom plate, there’s no recovery as you’re the only one who possesses the full private key. By storing the two plates in separate locations, users can avoid a single point of failure, adding an extra layer of security. These plates are resistant to fire, water, and corrosion, offering a level of security unmatched by paper backups.

How To Setup Your NGRAVE Zero

Setting up the NGRAVE Zero is straightforward, despite its high-security features. After powering on the device using the side button, you’ll follow on-screen prompts to create your wallet. The device also allows you to shuffle and freeze groups of numbers to ensure that not even NGRAVE has access to your private key. After this, you can download the NGRAVE Liquid app to authorize transactions via QR codes. This setup ensures that your keys and sensitive information stay offline, making the NGRAVE Zero a secure yet user-friendly option for crypto storage.

Setting up your NGRAVE Zero wallet is a breeze:

1. Power it on and select your language.
2. Create a secure PIN.
3. Register your fingerprint for added security.
4. Generate your private key and use the Graphene plates to backup the key by punching holes in the correct positions for each character.
5. Sync your wallet with the Liquid mobile app by scanning QR codes.
6. Add your crypto assets like BTC and ETH, and you’re good to go!

Pricing: Premium Protection Comes at a Cost

The NGRAVE Zero is a premium hardware wallet, and its price reflects this. Purchased separately, the Zero costs around $398 - Note: The dollar and euro amounts are equivalent - and the Graphene backup adds another $148, totaling $546. For those seeking a complete solution, the Combo Pack (which includes both the Zero and the Graphene) is available for $498, providing a total discount of $48, or roughly 9% off the combined price.

While this is a higher price point compared to other hardware wallets, it is a worthwhile investment for those who have large crypto holdings or want the highest level of security. Given its advanced features, tamper-proof design, and long-term durability, the NGRAVE Zero is well worth the money for users serious about protecting their crypto assets.

In a Nutshell

If you’re serious about safeguarding your crypto assets, the NGRAVE Zero wallet is hands-down the most secure solution on the market today. Its zero connectivity, anti-tamper features, and Graphene backup system make it a game-changer for cold storage. For anyone holding a large sum of crypto, the NGRAVE Zero wallet is a no-brainer — don’t risk your funds for a cheaper, less secure alternative.
