NGRAVE ZERO

The NGRAVE ZERO uses a multi-signature security model combined with Shamir Secret Sharing and Threshold Decryption. This means transaction authorization requires multiple cryptographic key shares, eliminating single points of failure. It is widely considered one of the most secure offline cold storage solutions for cryptocurrencies.

Yes, the NGRAVE ZERO operates on a 100% air-gapped architecture, meaning it has no Bluetooth, Wi-Fi, USB, or NFC connectivity. All transaction data is exchanged securely via QR codes scanned through the device's camera. This physical isolation completely protects the wallet from remote online hacks or network-based exploits.

If you lose the physical device, you can recover your cryptocurrency funds using your recovery seed phrase, which NGRAVE cleverly stores on a durable metal tablet called the Graphene. Because the ZERO uses multi-signature threshold decryption, your funds remain secure as long as your backup shares are safe. You simply restore the wallet onto a new NGRAVE device.

The NGRAVE ZERO supports a massive array of cryptocurrencies across multiple blockchains, including major networks like Bitcoin (BTC) and Ethereum (ETH), along with thousands of ERC-20 tokens. The development team continuously updates the firmware to expand support for other major coin ecosystems. Users can manage their entire portfolio entirely through the companion LIQUID mobile app.
