What is NGRAVE?
NGRAVE is a Belgian maker of the ZERO, an air-gapped hardware wallet with a 4-inch touchscreen that signs over QR codes with the LIQUID mobile app. The ZERO lists at 398 euros in its shop. NGRAVE says it supports 15 coins plus ERC-20 and ESDT tokens, and has operated since 2018.
How NGRAVE works
The NGRAVE ZERO has no USB data link, Bluetooth, NFC, Wi-Fi or 4G.
You start a transaction in the NGRAVE LIQUID app, which shows it as a QR code; the ZERO scans it, you review the details on its 4-inch touchscreen, and it returns a signed QR code for LIQUID to broadcast. LIQUID only ever sees your public addresses. The ZERO runs an operating system NGRAVE wrote from scratch, which the company says holds EAL7 certification, and it can hold more than 100 accounts plus passphrase-protected hidden wallets.
For backup, NGRAVE sells GRAPHENE, two stainless steel 316 plates the size of an A5 sheet. You punch your Perfect Key through the upper plate into the lower one, then store the plates in different places; neither plate alone reveals the key. NGRAVE says the plates resist up to 1,375 degrees Celsius (2,507 Fahrenheit). If you lose the upper plate, NGRAVE can send a replacement when you share your Ultimate Recovery Code. The ZERO also works with MetaMask and Rabby for DeFi signing.
How to start with NGRAVE
- Buy the ZERO from the NGRAVE shop, which has a United States storefront priced in USD.
- The site lists next-day shipping, free on orders above $300, payment by credit card, Bancontact or crypto, and a 30-day return window.
- Install LIQUID from the App Store or Google Play (NGRAVE says it works on iPhone 6 and later), generate your key on the ZERO, back it up, then sync the ZERO with LIQUID by QR code.
- NGRAVE's getting started videos walk through each step.
NGRAVE fees and limits
The ZERO lists at 398 euros in the NGRAVE shop, with taxes included but customs duties possibly due on import. The GRAPHENE backup costs extra. There is no subscription. Swaps offered from the NGRAVE menu run through Changelly and purchases through outside providers, so their fees and network gas apply on top of the hardware price.
Risks to know before using NGRAVE
- NGRAVE is self-custody: without your Perfect Key or GRAPHENE backup, lost funds cannot be recovered.
- The GRAPHENE upper plate recovery service means NGRAVE keeps data that can regenerate that plate, although the company says it has nothing on your lower plate.
- The LIQUID app page lists 15 coins plus all Ethereum and MultiversX tokens, so check the supported list for your exact asset before you move it.
