When researching hardware wallets, it’s easy to get overwhelmed by brand promises and technical specs tossed around. As someone who’s handled multiple devices over the years, I find direct comparisons helpful—they cut through marketing fluff and focus on what really matters. This review compares NGRAVE with three popular alternatives: Ellipal, Ledger, and Keystone. Since every user has different priorities, I’ll outline the core differences across security, usability, coin support, and backup options so you can decide what fits your cold storage strategy best.
If you want to understand NGRAVE specifically, my NGRAVE wallet review explains its unique features in detail.
To keep this objective, I tested devices based on:
By demonstrating how these areas stack up, I hope readers can replicate tests whether at home or in a retail setting.
One of the most talked-about features of NGRAVE is its fully air-gapped design. During my hands-on testing, NGRAVE uses QR codes to communicate transaction data between the device and the companion app, avoiding any physical connections like Bluetooth or USB. This dramatically lowers the risk of remote attacks.
Ellipal also emphasizes air-gapped security but approaches it differently. Their device uses QR codes for signing and does not connect via Bluetooth or USB either. However, its aluminum shell and sealed hardware create a tamper-evident design backing up the secure element.
| Feature | NGRAVE | Ellipal |
|---|---|---|
| Air-gapped communication | QR codes only | QR codes only |
| Secure element type | Certified secure element | Certified secure element |
| Tamper-proof casing | Yes | Yes |
| Connectivity methods | QR code only (no Bluetooth) | QR code only (no Bluetooth) |
What I noticed:
Both devices eliminate Bluetooth vulnerabilities. But NGRAVE's integration felt slicker during setup; the companion app paired seamlessly via scanned QR, and firmware updates could be done without connecting cables. Ellipal’s update process requires transferring firmware files manually via a microSD card, adding complexity.
If the concept of air-gapped signing via QR codes piques you, I detailed NGRAVE’s method deeper at NGRAVE security architecture.
Ledger wallets have been around since before 2017, making them one of the most recognized brands. Their devices rely on USB or Bluetooth connections, depending on the model. This connectivity flexibility arguably improves convenience but adds potential risks. Bluetooth, for example, increases the attack surface.
In my extended use, Ledger’s software ecosystem is mature with an extensive wallet app supporting thousands of tokens. Firmware updates are streamlined using Ledger Live software, which verifies update signatures cryptographically.
NGRAVE’s approach sacrifices some connectivity convenience (no Bluetooth or direct USB) for heightened security through its fully air-gapped method. Yet firmware updates, delivered via the companion app and scanned QR, maintain strong authenticity checks.
| Feature | NGRAVE | Ledger |
|---|---|---|
| Connectivity | QR codes (air-gapped) | USB & Bluetooth |
| Firmware update process | Via companion app QR scan | Via verified desktop app |
| User interface | Touchscreen + companion app | Button + Ledger Live app |
| Software ecosystem | Growing, device-specific | Established, multi-platform |
One trade-off: for users always on the go, the Ledger wallet’s Bluetooth option offers easier daily interaction. In contrast, NGRAVE’s design resonates more with those prioritizing security over convenience.
Keystone wallets offer impressive flexibility with support for both 12 and 24-word seed phrases and Shamir backup (SLIP-39). This backup method lets you split your seed phrase into multiple shares, adding layers to your recovery options.
NGRAVE currently supports 24-word BIP-39 seed phrases, verifiable within the device, and promotes metal backup plates for physical durability against disasters.
When setting up multisig wallets—a way to require multiple devices or keys to authorize transactions—both Keystone and NGRAVE support many third-party wallets, but Keystone shines with its broader multisig compatibility due to open standards and popular wallet integrations.
| Feature | NGRAVE | Keystone |
|---|---|---|
| Seed phrase length | 24 words (BIP-39) | 12 or 24 words + SLIP-39 |
| Backup method | Metal plates recommended | Metal + Shamir (SLIP-39) |
| Multisig compatibility | Supported (multiple wallets) | Highly compatible |
| Seed phrase entry method | Touchscreen input | Touchscreen + QR scan |
Why this matters:
If you want advanced backup strategies that hedge against losing portions of your recovery phrase, Keystone is strong. NGRAVE’s focus is on durability and secure on-device verification, suitable for those who prefer traditional BIP-39.

Choosing a hardware wallet often comes down to coin support. Here’s how these devices compare:
| Wallet | Bitcoin | Ethereum | Solana | Polkadot | Binance Smart Chain | Others |
|---|---|---|---|---|---|---|
| NGRAVE | Yes | Yes | Limited | Limited | Yes | Supports 20+ blockchains; expanding |
| Ellipal | Yes | Yes | Yes | Yes | Yes | 40+ blockchains and tokens |
| Ledger | Yes | Yes | Yes | Yes | Yes | 1500+ tokens via Ledger Live |
| Keystone | Yes | Yes | Yes | Yes | Yes | 30+ blockchains, plus native NFT support |
Ledger’s wider coin coverage is largely thanks to its mature ecosystem, but NGRAVE and Keystone focus on quality support for popular blockchains relevant for long-term self-custody.

Clearly, no hardware wallet is perfect. Here’s my take on their trade-offs:
| Wallet | Pros | Cons |
|---|---|---|
| NGRAVE | 100% air-gapped QR communication; strong tamper resistance; durable backup options | Limited coin support; lacks Bluetooth convenience |
| Ellipal | Air-gapped with sealed hardware; wide coin support | Firmware updates require manual transfer; less UX polish |
| Ledger | Mature software ecosystem; broad coin/token support; USB & Bluetooth options | Presence of Bluetooth adds attack surface; concerns over supply chain in past |
| Keystone | Flexible seed phrase options + SLIP-39; broad multisig integration | Less mainstream; fewer coin integrations compared to Ledger |
The key question is: do you prioritize security above all (NGRAVE), broad compatibility and convenience (Ledger), or advanced backups (Keystone)? Ellipal sits somewhere in the middle with strong physical security but clunkier user experience.
| Feature | NGRAVE | Ellipal | Ledger | Keystone |
|---|---|---|---|---|
| Air-gapped signing | Yes (QR only) | Yes (QR only) | No (USB & Bluetooth) | Yes (QR and USB options) |
| Secure element | Certified SE | Certified SE | Certified SE | Certified SE |
| Firmware updates | Via app, QR scan | Manual via microSD | Ledger Live app | OTA updates, QR support |
| Seed phrase backup | 24 words, metal plate | 12 or 24 words | 24 words | 12 or 24 + SLIP-39 |
| Multisig support | Yes | Limited | Yes | Yes |
| Supported coins | 20+ | 40+ | 1500+ | 30+ |
| Connectivity | QR only | QR only | USB & Bluetooth | QR, USB |
| Tamper-proof casing | Yes | Yes | Yes | Yes |
Picking a hardware wallet comes down to your personal comfort with trade-offs. If you value a true air-gapped device where your private keys never touch a connected cable or Bluetooth, NGRAVE stands out in my experience. But if ecosystem maturity and broad coin support matter more, Ledger’s extensive software is compelling.
Ellipal offers a middle ground on security with slightly clunkier updates, while Keystone’s flexibility in seed phrase backups and multisig setups appeals to advanced users who want customizable recovery options.
Not everyone needs a multisig fortress, but understanding which cold wallet fits your intended security level and daily workflow makes all the difference.

Yes. All devices use seed phrases to regenerate private keys on a new hardware wallet. NGRAVE and most competitors recommend storing these on metal backup plates or Shamir shares to withstand fire, water, and physical damage.
Since the wallets are non-custodial and rely on your seed phrase, you can restore your crypto independently on compatible wallets. Firmware support may slow if the company disappears, but recovery remains intact.
Bluetooth introduces additional attack vectors. Some users see it as a risk, especially if combined with poor supply chain security. Fully air-gapped devices like NGRAVE avoid this by design, but again, it’s a trade-off with convenience.
