Facts about the Ngrave ZERO
Ngrave ZERO FAQ
How does the Ngrave ZERO achieve a fully air-gapped security model compared to traditional hardware wallets?
Unlike standard hardware wallets that rely on USB, Bluetooth, or NFC connections to transmit data, the Ngrave ZERO operates entirely offline. It uses a secure, transparent QR code scanning system to communicate with the LIQUID mobile app. This complete physical isolation eliminates external attack vectors, ensuring that your private keys are never exposed to an internet-connected device or network protocol vulnerabilities.
What makes the EAL7 certification of the Ngrave ZERO significant for institutional-grade asset protection?
The Ngrave ZERO is the first cryptocurrency hardware wallet to achieve the Common Criteria EAL7 certification, the highest possible security evaluation level in the industry. This means its operating system and cryptographic architecture have undergone the most rigorous independent mathematical verification and vulnerability testing, guaranteeing an unparalleled level of resilience against both physical tampering and complex logical attacks.
How does the 'Perfect Key' generation process mitigate vulnerabilities found in standard BIP39 mnemonic seed phrases?
Instead of relying on a pre-generated or purely device-generated seed phrase, the Ngrave ZERO uses a biometric fingerprint scan, ambient light sensors, and user interaction to introduce true randomness into the key generation. Furthermore, the resulting 'Perfect Key' is represented in hexadecimal format, which removes the linguistic vulnerabilities and dictionary attack risks associated with standard BIP39 recovery words.
Can I recover my assets using a standard 24-word seed phrase if I lose access to the Ngrave ZERO device?
While the native 'Perfect Key' is a 64-character hexadecimal string, the Ngrave ZERO is fully compatible with the BIP39 standard. During the setup process, users have the option to generate or import a standard 12, 18, or 24-word seed phrase. This ensures that you can still recover your funds on alternative compatible hardware wallets in the event of device loss, maintaining interoperability within the broader crypto ecosystem.
What advanced anti-tampering mechanisms protect the physical integrity of the Ngrave ZERO hardware?
The device is constructed with military-grade casing and incorporates multi-layered anti-tampering defenses. If any physical intrusion or sophisticated side-channel attack is detected, the built-in Secure Element instantly triggers a self-destruct protocol. This irreversible process wipes all cryptographic keys and sensitive data from the device, ensuring that an attacker cannot extract your assets even if they gain physical possession of the hardware.
