NGRAVE ZERO is an air-gapped, fingerprint-protected touchscreen that costs USD 398 and, when I checked, was sold out. The Ledger Flex is easier to buy, cheaper and wireless. If you want the most isolated signing device and can get one, look at NGRAVE. If you want a wallet you can buy this week, look at Ledger.

What Happens If You Lose Your NGRAVE ZERO Or Ledger Flex?

Ledger Flex: Your coins are recorded on the blockchain, not stored inside the device. Recovery depends on the backup: 24-word Secret Recovery Phrase; Ledger Recovery Key (NFC) now included with the Flex; optional paid Ledger Recover (Coincover), availability depends on country of ID document. Keep that backup offline and never type it into a website or app. 7 security issues are on record for the maker, the latest on 2026-08-27 (Security Bulletins 023, 024, 025: signing-review bypasses).

Which Is More Secure, NGRAVE Or Ledger?
NGRAVE's headline is a Common Criteria EAL7 certification, which it says no other crypto hardware wallet has. That is the company's own claim, and I could not confirm it against a certification body page, so treat it as a claim. The ZERO has no USB, Bluetooth, NFC, WiFi or 4G at all. It transacts by QR code only, with a 4 inch colour touchscreen, a fingerprint sensor and unlimited hidden wallets through a passphrase. The Ledger Flex has a lower EAL6+ element and connects over Bluetooth, NFC and USB-C.
How safe is crypto on Ledger? In the sources I used, no seed has been extracted from a current device, but the company's disclosed list is long: the 2020 shop database leak, the 2023 Connect Kit supply-chain attack and three signing-review bulletins in August 2026 (Donjon). I found no documented incident for NGRAVE, though a short record is also a sign of a smaller user base and fewer researchers poking at it. The open-source status of NGRAVE's firmware was not stated on its pages.
Which Is Easier To Use?
The ZERO's QR-only design means a companion app has to show and scan codes for every action, and NGRAVE's app support details were not on the pages I fetched. Backup is a 24-word BIP-39 seed or a hexadecimal 'Perfect Key' convertible both ways, and the combo packs include a backup product. The Ledger Flex is simpler: Bluetooth to the Ledger Wallet app on iOS, Android or desktop, a 10 hour battery and an E Ink touchscreen.
Which Supports More Coins?
NGRAVE's own page contradicts itself. The hero line says '+3 500 coins and tokens' while the specification line says 15 coins plus all Ethereum and MultiversX tokens. I would trust the narrower number until NGRAVE clarifies. Ledger says 500+ crypto in its app, including Bitcoin, Ethereum, Solana and XRP. Always check the coin you hold.

Because NGRAVE ships from Belgium, CBSA courier rules for parcels from outside the US and Mexico apply: duty and tax free only up to CAD 20, and above that duties and taxes apply. On a USD 398 device that adds up, so build the extra into your budget. Check stock before you plan around it.
How Do They Work With Canadian Exchanges?
Both accept coins from any exchange to the address you generate. Coinbase's 'Sending to myself' option, Kraken's Travel Rule pop-up at CAD 1,000 or more and NDAX's 'Who are you sending to?' prompt are the screens you will see. Moving coins between wallets you own is not a taxable disposition per the CRA. See the Canadian crypto tax guide.
There is a middle path worth knowing. A QR-only device is the strictest form of isolation, but plenty of Canadians never need it. The real-world loss paths are phishing, a photographed recovery phrase and sending to a wrong address, and none of those depend on EAL7 versus EAL6+. If you are buying mainly to protect a modest balance from exchange risk, a simpler device that you will actually use is better than a rare one that sits in a drawer because the setup annoys you.
Before you buy either, look at what you hold and how often you move it. A holder with one large Bitcoin position who sends twice a year gains little from any particular certification level, and a holder moving tokens across chains weekly will care a lot more about app support and coin lists than chip grades. Write down your own use case first, then pick the device that fits it, not the one with the best marketing line.
Which Should You Choose?
Choose NGRAVE ZERO if you want the most isolated device, hold coins it supports and are happy to wait for stock and pay customs. Choose the Ledger Flex if you want to buy now, pay less and use a mainstream app. Is Tangem better than Ledger? For many Canadians, a USD 54.90 two-card Tangem set with my code is the cheaper simple route, see Tangem Vs Ledger. My top three are in the best crypto wallets in Canada list.
What Has Happened With NGRAVE And Ledger?
Ledger published Security Bulletins 023, 024 and 025 on signing-review bypasses (Donjon).
Ledger's payment partner Global-e reported unauthorised cloud access involving international order data (The Block).
Frequently Asked Questions
How Safe Is Crypto On Ledger?
No seed extraction from a current Ledger device appears in my sources, but Ledger has disclosed data leaks, a dApp supply-chain attack in 2023 and signing-review bulletins in 2026. Buy direct and never share your phrase.
What Are The Top 3 Crypto Wallets?
My ranking is Trezor Safe 7, Tangem and Ledger Flex. NGRAVE ZERO is not in my top seven.
Tangem is a cheaper, simpler NFC card with a seedless backup, but a July 2026 laser attack on its card chip cannot be patched. Ledger is closed-source with a screen. They suit different people.
