Detailed Review
NGRAVE is the trade name of Hestara SRL, a Belgian company with its registered office at Venelle des Platanes 2, 1300 Wavre. Its terms are governed by Belgian law, with disputes going to the Dutch-speaking courts of Brussels.
The NGRAVE ZERO is an air-gapped hardware wallet. NGRAVE says it has no USB, Bluetooth, NFC, WiFi or 4G, and that every transaction is signed through QR codes. The ZERO page says it integrates with MetaMask and Rabby.
Can NGRAVE ZERO work alongside MetaMask?
The NGRAVE ZERO page states that the device integrates with MetaMask and Rabby Wallet, so staking, swapping and bridging can happen with signing done offline. That makes NGRAVE an add-on to MetaMask as much as a replacement.
For people leaving MetaMask entirely, the NGRAVE LIQUID app is the companion software, though the pages we read describe it only briefly.
What does NGRAVE say about security?
NGRAVE says ZERO is the only crypto hardware wallet with EAL7 certification and that its operating system was built from scratch. The device uses a biometric sensor, an 8-digit PIN and tamper protection that wipes the device if it is opened.
These are vendor claims, and we did not check the certificate. NGRAVE also offers passphrase hidden wallets and a Perfect Key convertible to a 24-word phrase.
How many assets does ZERO hold?
NGRAVE states support for 3,500 coins and tokens and more than 100 accounts on one device. A 4 inch colour touchscreen shows transaction details before signing.
The partners page links third parties for swaps (Changelly), private trading (BTC Direct) and crypto-backed loans (Arch Lending).
Limitations to Consider
Air-gapped QR signing takes more steps than a connected device. NGRAVE does not show the ZERO price on the pages we read. The legal pages note that the Arch Lending service is run by ChainFi Inc, which does not serve customers outside the United States. Open-source status is not stated on the pages we read. Trezor publishes its code.
Who Should Use NGRAVE
Security-focused holders who want offline QR signing and keep MetaMask or Rabby for dApp access.
