NGRAVE ZERO wallet overview

NGRAVE ZERO Wallet

The NGRAVE ZERO keeps your crypto fully offline, never connecting to the internet at any point. It doesn’t use USB, Bluetooth, WiFi, or NFC — instead, it transfers data through QR codes, so it stays completely isolated.

The device has a crisp 4-inch touchscreen and built-in fingerprint scanner, all packed into a durable metal body that’s tough to tamper with. Its security setup includes a certified chip, your fingerprint, and a metal backup system called GRAPHENE. This isn’t just another wallet — it’s a secure vault built from the ground up to keep your assets safe.

Key features of NGRAVE ZERO

100% offline operation

NGRAVE ZERO stays disconnected — no Wi-Fi, Bluetooth, or cables involved. It uses only QR codes to communicate with the NGRAVE LIQUID app for signing and sending transactions. This keeps your private keys isolated from online threats at all times.

Without any connection to the web, malware and phishing attempts don’t stand a chance — unlike wallets that rely on USB or Bluetooth.

Military-grade security

With its EAL7 certification — the highest level of security testing — ZERO uses a chip trusted in defense and identity systems. Your private keys are created and stored completely offline.

It even checks your fingerprint — no match, no transaction. This adds a strong layer of personal protection that keeps your wallet truly yours.

GRAPHENE recovery solution

Unlike fragile paper seed backups, NGRAVE gives you GRAPHENE — a recovery system made from two solid steel plates. It’s built to survive fire, water, and physical impact.

The key is split between the plates, so even if one is stolen, it’s useless without the other. It’s a smarter, safer way to protect your recovery phrase.

Pros and cons of NGRAVE ZERO

Stays completely offline at all times. You never plug it in — ever — which makes it nearly immune to malware and remote attacks.
QR-based communication avoids data leaks. Unlike USB or Bluetooth, QR codes keep data flow one-way and traceable.
Fingerprint protection adds physical security. Even if someone steals your device, they can't access your wallet without your print.

You can’t connect it, even if you want to. No USB or Bluetooth means you must rely on scanning QR codes, which can feel slow if you're trading often.
Limited coin support compared to others. It doesn’t yet support as many altcoins as bigger-name hardware wallets.
No integration with third-party wallets. ZERO works only within its own ecosystem, which limits compatibility with popular platforms.

NGRAVE ZERO security review

100% Air-gapped design

The distinctive security characteristic of NGRAVE ZERO lies in its entirely offline architecture. It does not interact through any wireless or wired connections. Transactions are securely signed offline using QR codes, effectively mitigating risks associated with network vulnerabilities.

This provides a significant benefit over other wallets employing USB or Bluetooth, both of which can introduce vulnerabilities to malware or unauthorized access.

EAL7 secure element (highest on market)

The ZERO integrates an EAL7-certified secure chip — typically reserved for high-level governmental security applications. This secure chip safeguards private keys and internally manages sensitive operations, thereby preventing external interference.

It ensures cryptographic data remains strictly contained within the device, even when performing Firmware updates or processing transactions.

Biometric fingerprint security

Incorporating biometric fingerprint authentication enhances the wallet’s physical security measures. Only fingerprints that have been officially registered can gain access, significantly reducing the likelihood of unauthorized entry, even if the device is misplaced or stolen. Additionally, it lessens the chance that someone may guess your PIN or bypass other security features.

GRAPHENE recovery backup system

The GRAPHENE backup system utilizes two laser-etched stainless steel plates to securely store your seed phrase offline in a highly durable and fireproof manner. Compared to paper backups, it offers greater resistance, and unlike cloud-based options, it presents fewer security risks. Splitting the recovery phrase into two separate locations substantially decreases the threat of loss or theft.

Offline firmware updates

NGRAVE ZERO facilitates Firmware updates via QR codes, allowing users to download Firmware updates onto a smartphone or computer, and then scan these with the wallet without requiring physical cables or connections.

This procedure safeguards the wallet from vulnerabilities that may arise during Firmware installations — common points of exploitation in some cold storage devices.

Tamper-proof design and anti-extraction

The wallet employs a robust and tamper-resistant exterior. In the event of attempted physical breach, it is designed to automatically erase its memory, effectively securing private keys from unauthorized access.

Such tangible security, coupled with advanced cryptographic measures, renders data extraction from the device exceedingly challenging for intruders.

Supported coins & tokens

The NGRAVE ZERO hardware wallet offers top-tier security and wide crypto support. Alongside major coins like BTC and ETH, it also supports lesser-known assets such as:

Groestlcoin (GRS);
MultiversX (EGLD, formerly Elrond).

The ZERO is also compatible with:

All ERC20 tokens on the Ethereum network;
All ESDT tokens on the MultiversX network.

Users can manage thousands of tokens by sending them to their wallet addresses and syncing with the LIQUID app — even if the tokens aren’t visible on the dashboard. This makes ZERO a flexible and secure solution for both mainstream and niche portfolios.

NGRAVE ZERO price & fees

When evaluating the NGRAVE ZERO hardware wallet, it's essential to consider both its upfront cost and the value it offers. Priced at $398, the ZERO positions itself at the premium end of the hardware wallet market. For those seeking a comprehensive security solution, NGRAVE offers the COMBO PACK, which includes the ZERO wallet and the GRAPHENE backup system, priced at $498. This combination provides a robust approach to safeguarding your cryptocurrency assets.

Beyond the initial purchase, NGRAVE ensures transparency by not imposing additional fees for standard operations such as generating keys, signing transactions, or accessing its companion app. However, users should be aware of potential costs associated with accessories and backup solutions. For instance, the GRAPHENE backup system is available separately for $148, and accessories like a screen protector and an extra USB-C cable are priced at $28 USD and $18, respectively.

How to use NGRAVE ZERO: A step-by-step guide

Before getting NGRAVE ZERO, check these steps below:

Step 1: Set up the device

Set up the device

Power on your NGRAVE ZERO and go through the onboarding process. You’ll generate your private keys directly on the device, never touching the internet.

You’ll also scan your fingerprint and create a PIN code for added security. These steps ensure that no one but you can access the device.

Step 2: Back up with GRAPHENE

Back up with GRAPHENE

Use the included stainless steel plates to back up your recovery phrase. You’ll etch your keys onto the GRAPHENE plates following the instructions.

Store the two halves separately to maximize protection. If your device is ever lost or damaged, this is your way back in.

Step 3: Install the LIQUID app

NGRAVE LIQU<span translate="no">ID</span> app on the App Store

NGRAVE LIQUID app on theApp Store

Download and install the LIQUID app on your phone. Use it to manage portfolios and prepare unsigned transactions.

No login or personal data is required, and the app doesn’t store your private keys.

Step 4: Transfer and receive funds

Transfer and receive funds

To receive funds, generate a receiving address on ZERO and scan it with LIQUID. For sending, create the transaction in LIQUID, scan the QR code on ZERO to sign it, and scan the signed code back into the app.

This method ensures your private key never leaves the device, maintaining full offline security.

Alternatives to NGRAVE ZERO

Looking something other than NGRAVE ZERO? Here are some of its best alternatives:

ELLIPAL Titan

ELLIPAL Titan 2.0 cold wallet

Similar to the ZERO, the ELLIPAL Titan also relies on offline QR code technology. It accommodates a broader range of tokens and features a robust build, although its internal security component is not as sophisticated as the one in ZERO.

It represents a reliable option for individuals seeking offline security at an affordable price.

Keystone Pro

Keystone 3 Pro

The Keystone Pro provides transparent firmware and fingerprint authentication. It achieves offline security through QR codes and integrates seamlessly with MetaMask.

Nevertheless, it does not offer the sophisticated backup capabilities and hardware-based security found in the ZERO.

Ledger Stax

Ledger Stax emphasizes ease of use through an e-ink screen and compatibility with numerous cryptocurrencies. However, it connects via Bluetooth and USB, potentially increasing vulnerability.

It suits individuals who value ease of use and broad token compatibility above complete offline security.

Storing crypto on exchanges: An alternative to hardware wallets

Keeping your crypto on centralized exchanges like Binance or Coinbase may seem convenient, but it involves serious risks. Regulation is one of the key parameters to judge the security of any exchange. In line with the same, the top exchanges known for their reliable security (and strict regulatory oversight) are listed in the table below:

Best regulated crypto exchanges

Do note that exchanges are prime targets for hackers and have been breached before. Moreover, you don’t control your private keys, meaning you technically don’t own your crypto. If the exchange gets hacked or freezes accounts, your assets could be lost.

For long-term holders or those with large portfolios, hardware wallets offer much better protection and peace of mind.

NGRAVE’s zero-connect key generation and split-plate recovery change crypto security forever

Most beginners think seed phrases are static, unchangeable lifelines — but with NGRAVE ZERO’s “Perfect Key” system, you’re not locked into that idea. You can actually generate entirely new private keys on the device, offline, with zero internet connection, using real-time entropy (like light, biometrics, and user input). This means you don’t have to trust a pre-generated phrase or hope your computer didn’t get compromised during setup. You’re building randomness yourself. It’s like hand-forging your vault key instead of downloading it.

Also, here’s a killer feature most people don’t talk about: NGRAVE’s “Graphene” backup is made of two interlocking metal plates — one holds part of your seed data, the other holds a decoder layer. Separately, they’re meaningless. Together, they restore your wallet. This split-metal design gives you plausible deniability. If someone finds one plate, it tells them nothing. Store one at home and one offsite — and unlike basic seed phrases, this method survives fire, water, and break-ins.

Conclusion

NGRAVE ZERO is built for users who value security above all else. Its air-gapped design, biometric access, and high-grade secure chip make it one of the safest options on the market in 2026. It might not be the most flexible wallet in terms of coin support or DeFi use, but when it comes to protecting your crypto from theft or hacking, it sets a high bar. If that’s your top priority, the NGRAVE ZERO is absolutely worth considering.

FAQs

Can I use NGRAVE ZERO for multi-signature wallets?

Not yet. NGRAVE ZERO doesn't currently support multisig setups like those used in collaborative wallets. It’s built for single-user, high-security storage. If you're managing a shared fund or team wallet, you'll need to use a different solution — though multisig may be added in future firmware updates.

What happens if I lose the NGRAVE ZERO device but still have the GRAPHENE backup?

No worries — you can fully restore your wallet with just the GRAPHENE plates and a new NGRAVE ZERO. Since your private keys are generated offline and stored in the plates, the device itself isn’t critical to recovery as long as your backup is safe.

Does NGRAVE support NFTs?

Yes, but only for ERC-721 and ERC-1155 tokens on Ethereum, and ESDTs on MultiversX. You won’t see fancy NFT previews, but you can securely store and track NFT assets through the LIQUID app, which reads wallet activity even if the NFTs aren’t shown in-app.

Can I travel with NGRAVE ZERO through airport security?

Yes! It’s just a secure storage device with no wireless signals — airport scanners won’t flag it as suspicious. But as a precaution, avoid storing both GRAPHENE plates and the device in the same luggage while traveling.
