Recommendations based on real-world use cases
Keycard Shell
$129Best for:
Built-in batteryFull node supportAndroid supportiOS support
Pros
- +Private keys stay on a removable Keycard with an NXP JCOP4 P71 secure element (CC EAL6+ chip certification)
- +No Wi-Fi, Bluetooth, cellular or NFC on the Shell; signing runs over QR codes via a built-in camera
- +MIT-licensed firmware with reproducible builds; hardware design files published under CERN-OHL-S
- +Two Keycards in the box, so a second card holding the same seed can serve as a working backup
Cons
- −Bitcoin and EVM chains only; Solana and other non-secp256k1 networks are not supported
- −Taproot arrived only in firmware 1.4.0 for Keycard v4 cards; the product page still lists it as unsupported
- −Needs a third-party software wallet to build and broadcast every transaction
- −No published third-party security audit of the Shell firmware or the Keycard applet
Ngrave Zero
$398Best for:
Water resistanceBuilt-in batteryAndroid supportiOS support
Pros
- +Air-gapped: transactions move by QR code; USB-C is used only for charging and firmware updates
- +8-digit PIN on a scrambled keypad; the device wipes itself after 10 wrong attempts
- +4-inch 480 x 800 touchscreen, built-in camera, 1200 mAh battery and an IP55-rated metal-alloy body
- +Secure boot, GPG-signed firmware verifiable by hash, no downgrades and a genuine check at first use
Cons
- −Closed-source firmware; WalletScrutiny's verdict is 'no source', so builds cannot be checked
- −No published audit; EAL7 is an NGRAVE claim, and the public EAL7 certificate does not name the ZERO
- −LIQUID collects usage data via Google Analytics/Firebase; its notifications were hijacked in Oct 2026
- −$398, plus $148 for the GRAPHENE steel backup; no WalletConnect, no staking, no multisig documented

Keycard Shell vs Ngrave Zero: Frequently Asked Questions
Answers about Keycard Shell vs Ngrave Zero
Is Keycard Shell better than Ngrave Zero?
On the numbers, Keycard Shell comes out ahead — 66/100 vs 56/100 — but 'better' isn't quite the right frame. Ngrave Zero is easier to use (71/100 usability), which matters more for some buyers than overall score does. If overall rating is what you actually weigh first, take Keycard Shell. If ease of use is the constraint that shapes your decision, Ngrave Zero is the smarter buy. Either way, both are real hardware wallets — neither is a mistake.
How much do Keycard Shell and Ngrave Zero cost?
Keycard Shell costs $129, Ngrave Zero costs $398. These are list prices for the standard edition from official manufacturer stores. A few things worth knowing: hardware wallet prices barely move during the year, so 'waiting for a sale' rarely pays off — Black Friday is the one exception, with 10–20% off being typical. Avoid third-party listings even if they're cheaper; the supply chain risk on a tampered device wipes out any savings the first time you load funds. And don't buy a 'used' hardware wallet, ever — even if it claims to be reset.
Is Keycard Shell waterproof?
No — Keycard Shell has no official water or dust resistance rating, so treat it like any other small electronic. A spilled drink or a rainstorm in your jacket pocket is enough to brick it. Ngrave Zero, by contrast, carries an IP55 rating, which means it's tested against dust and pressurized water — that's the device you'd actually take camping or to a beach. For most people, water resistance isn't a deciding factor, but it matters if you travel light or carry your wallet daily.
Which wallet is better for DeFi and Web3: Keycard Shell or Ngrave Zero?
Keycard Shell — and the gap is bigger than the spec sheets make it look. Keycard Shell has WalletConnect built in, which means you sign DeFi transactions directly from a hardware wallet without exposing keys to a hot wallet. Ngrave Zero can technically work with DeFi via third-party software, but every extra step is one more place an attacker can intercept the transaction you're approving. If you're going to be clicking 'Sign' on smart contracts more than once a month, the difference compounds fast.
Keycard Shell vs Ngrave Zero: which has better backup options?
Keycard Shell uses a 24-word seed phrase with optional Shamir Secret Sharing for split backups. Ngrave Zero uses a standard 24-word seed phrase. Both work — but they reflect different ideas about what 'backup' should be. The seed phrase approach (BIP-39) is the open industry standard: portable across most wallets, well-documented, and recoverable on any compatible device. The downside is well-known too — it's a piece of paper that's a single photograph or careless moment away from disaster. Card-based backups can't be photographed and don't write themselves down, but they're proprietary, which means you trust one manufacturer to stay in business and keep the format alive. Pick based on which failure mode worries you more.
Is Keycard Shell more secure than Ngrave Zero because it's open-source?
Not automatically — and this is a more nuanced question than the marketing suggests. Open-source (Keycard Shell) lets anyone (researchers, hobbyists, paranoid users) read the firmware and verify there are no backdoors. That's the strongest possible trust signal. Ngrave Zero keeps source code private but compensates with paid third-party audits from and certifications like CC EAL5+/EAL6+ on the secure element. Open-source is the more transparent posture; audited closed-source can still be cryptographically airtight. Our honest take: if open-source is the deciding factor for you philosophically, pick Keycard Shell — but don't dismiss Ngrave Zero as 'less secure' purely on that basis.
Where to buy Keycard Shell at the best price?
Always buy Keycard Shell from the official Keycard store — never from Amazon, eBay, or third-party marketplaces, even if the price looks better. Hardware wallets have been physically tampered with in the supply chain before (compromised devices shipped to unsuspecting buyers, then drained the moment funds were loaded). Buying direct from Keycard gets you a sealed unit with full warranty, firmware integrity, and a clean chain of custody. Free shipping and occasional discounts at the source make the price difference negligible anyway.
Do Keycard Shell and Ngrave Zero come with a warranty?
Yes — both ship with a manufacturer warranty (typically 1–2 years) when bought from the official store. That said, a hardware wallet warranty is mostly about hardware defects, not lost funds. If the device fails, the manufacturer will replace it — but your seed phrase or backup cards are what actually restore your crypto onto the new device. The warranty is real but secondary; what protects your funds is your backup discipline, not a piece of paper from {{wallet1}} or {{wallet2}}.
