When it comes to long-term crypto security, hardware wallets remain one of the most reliable methods to protect private keys. I’ve spent several months testing and analyzing the NGRAVE wallet to give you an objective, hands-on NGRAVE wallet review. This review doesn’t just skim over marketing claims—I roll up my sleeves to assess setup, daily use, security, and real-world practicality.
If you’re considering a cold wallet option for self-custody, this review should help clarify what NGRAVE offers without hype or bias.
Right out of the box, the NGRAVE wallet felt premium and thoughtfully designed. The packaging is minimalistic, emphasizing secure supply chain integrity—something I tested by checking for tamper-proof seals and QR code authenticity.
Inside, you'll find the wallet itself, an associated smartphone app QR code, recovery materials, and a guide. The hardware’s surface finish is matte black, lending a modern but low-profile look. Compared to some bulkier wallets, NGRAVE’s form factor is sleek and pocket-friendly.
During unboxing, I noticed no unusual odors or flimsy materials, which can sometimes hint at counterfeit devices—a subtle but important check.
What I appreciated was NGRAVE’s approach to initial setup. The wallet is designed to be air-gapped, meaning it never connects directly to the internet or external devices like computers or phones during key generation or signing. This setup is handled through scanning QR codes displayed on the wallet's small e-ink screen with a companion mobile app.
Here’s my step-by-step setup rundown:
What stood out was the simplicity despite being highly secure—no cables, no risk of Bluetooth hacks, and no reliance on possibly compromised computers.
The heart of any hardware wallet is its security design, and NGRAVE employs several advanced methods worth discussing.
One potential downside is that the device’s e-ink display is small and monochrome; navigating complex transactions might require patience compared to larger-screen alternatives.

In everyday use, I found NGRAVE’s wallet experience generally smooth but distinct from popular USB plugged wallets.
The air-gapped model demands patience when scanning QR codes for each transaction signing. This is a trade-off between security and convenience. In my testing, handling 1-3 transactions per week was fine; heavy DeFi users might find this clunky.
The companion mobile app is essential here, serving as the wallet’s communication bridge. It lets you prepare unsigned transactions offline, then send them to the hardware wallet via QR scanning. After approval, signed transactions are scanned back to the phone for broadcasting.
I also tested the wallet’s PIN security; in my experience, it does a good job preventing unauthorized access while being easy enough to set up with no recovery risk if forgotten.
Firmware updates for hardware wallets are not just routine— they patch vulnerabilities and add new functionality to keep your assets safe.
With NGRAVE, updates are downloaded on your phone but validated and installed offline on the device via QR codes, maintaining the air-gap.
Here’s how I performed updates:
This method minimizes supply chain or man-in-the-middle attacks. If you want a detailed update walkthrough, see the NGRAVE Firmware Updates guide.
Seed phrase backup is arguably the most critical step for any self-custody holder. NGRAVE uses a 24-word BIP-39 seed phrase—a standard in the industry offering strong entropy and recovery power.
The wallet supports metal backup plates for storing seed phrases, which resist fire, water, and time degradation much better than paper.
I personally tested the assembly and storage of a metal backup with NGRAVE’s recommended setup. It was straightforward; however, it requires some investment in protective cases and a secure physical location.
They do not currently support Shamir backup (SLIP-39), which some hardware wallets offer to split seed phrases into multiple parts for added security.

In use, NGRAVE supports a solid variety of blockchains:
| Blockchain | Support Details |
|---|---|
| Bitcoin (BTC) | Full native support, SegWit ready |
| Ethereum (ETH) | ERC-20 tokens supported through app |
| Solana (SOL) | Supported with native address generation |
| Others | Several other altcoins via app |
While it covers the essentials, some niche DeFi tokens or emerging chains may require third-party solutions or additional software layers.
The wallet does not support multi-signature setups natively, but transactions can be managed externally through certain multisig-compatible wallets (learn more in NGRAVE Multisig).
Here’s a quick comparison table highlighting key feature differences between NGRAVE and common hardware wallet types:
| Feature | NGRAVE Wallet | Typical USB Hardware Wallet | Bluetooth Hardware Wallet |
|---|---|---|---|
| Connectivity | Air-gapped (QR codes) | USB cable | Bluetooth |
| Secure Element | Yes | Usually yes | Usually yes |
| Seed Phrase Length | 24 words | 12 or 24 words | 12 or 24 words |
| Multi-signature Support | Limited (via external apps) | Supported (varies) | Supported (varies) |
| Firmware Updates | Offline via QR codes | USB connected | Bluetooth or USB |
| Ease of Use | Medium (QR scanning needed) | High (plug & play) | High (wireless convenience) |
| Security Considerations | Very Low attack surface | Medium | Higher due to wireless risks |
Naturally, your choice will hinge on how you weigh convenience versus security. And I think that’s what differentiates NGRAVE well—the clear priority on minimizing attack vectors.

After spending good time with the NGRAVE wallet, I find it a compelling choice for holders who prioritize airtight security and don’t mind trading some convenience for peace of mind. If you’re looking for a very secure, air-gapped cold wallet with solid crypto support and durable seed phrase backup options, it’s worth considering.
That said, if your use case involves daily, quick trades or DeFi interactions, you might want to compare its workflow with more USB or Bluetooth-oriented wallets.
Remember, no hardware wallet completely eliminates all risk—physical security of backups, vigilance against phishing, and proper passphrase usage all play huge roles.
