BitBox02 Nova vs Ngrave Zero vs OneKey Pro: Frequently Asked Questions

Answers about BitBox02 Nova vs Ngrave Zero vs OneKey Pro

Is BitBox02 Nova better than Ngrave Zero?
On the numbers, BitBox02 Nova comes out ahead — 75/100 vs 61/100 — 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 BitBox02 Nova. 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 BitBox02 Nova and Ngrave Zero and OneKey Pro cost?
BitBox02 Nova costs $149, Ngrave Zero costs $398, OneKey Pro costs $278. 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.
Can BitBox02 Nova be used on iPhone (iOS)?
No — BitBox02 Nova has no iOS app today, and there's no public roadmap for one. It works fine with Android, Windows, macOS, and Linux, but iPhone users are out of luck. If your primary device is an iPhone and you don't want a separate computer just to manage crypto, Ngrave Zero is the practical pick: it has a native iOS app and the full feature set works over Lightning or Bluetooth.
Is BitBox02 Nova waterproof?
No — BitBox02 Nova 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: BitBox02 Nova or Ngrave Zero?
BitBox02 Nova — and the gap is bigger than the spec sheets make it look. BitBox02 Nova 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.
BitBox02 Nova vs Ngrave Zero: which has better backup options?
BitBox02 Nova uses a standard 24-word seed phrase. 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 BitBox02 Nova 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 (BitBox02 Nova) 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 Common Criteria EAL7 certification of integrated ProvenCore TEE (Prove & Run) 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 BitBox02 Nova — but don't dismiss Ngrave Zero as 'less secure' purely on that basis.
Where to buy BitBox02 Nova at the best price?
Always buy BitBox02 Nova from the official BitBox 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 BitBox 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.
