NGRAVE ZERO

Editorial assessment

As a hardware wallet, the NGRAVE ZERO is the flagship of the Belgian NGRAVE series: large touch display, battery and consistent air gap without a classic USB signature path. The included GRAPHENE steel backup is its own mechanical kit — not the same as paper BIP39 or microSD at BitBox. Cheaper air-gapped alternatives and USB sticks serve different budgets; This is about premium hardware with manufacturer claims for EAL7-OS and EAL5+-Secure-Element.

Operation is isolated: QR communication instead of a permanently connected cable. Multi-chain including Solana is documented, Bluetooth and NFC are missing. Firmware and client are closed - if you prioritize open source transparency, you will find other profiles at Trezor, BitBox or OneKey. Desktop OS support is unknown in features; The workflow relies on the touch device plus the accompanying app.

The price range is well above Nano, BitBox02 and many OneKey Classic models - specific RRP values are in the purchase features. This is not a “better because it is more expensive” argument, but rather the classification: a lot of housing, steel backup and certification marketing in one package. EAL information is a manufacturer claim, not an independent product certification by JMRKT.

Opposite Keystone or OneKey Pro, premium air gap devices share the QR idea, differ in backup philosophy and software openness. If you're looking for a simple USB stick setup, you've come to the wrong place; If you want maximum isolation plus a physical backup kit, compare within the air gap upper class. EAL information is a manufacturer claim, not an independent product certification by JMRKT.

Technical details, price ranges and OS limits are in the features table - not in this continuous text.
