About NGRAVE
Fully offline hardware wallet, your private keys are never exposed to any online device. Built in partnership with world leaders in nano-technology & hardware security. The most advanced wallet generation process in the world. NGRAVE provides a mobile app to directly sync all the generated accounts from the ZERO. That way, the user can easily consult his real-time balances or ask to receive a transaction. Communication between the ZERO and the app occurs through QR-codes. This way, the app never has access to the secret keys on the ZERO. Hence, the secret keys are never exposed to any online attack vector. Not even when signing transactions. Create a computationally unique, unbreakable, & unpredictable secret key with a strong True Random Number Generation (TRNG) process. NGRAVE takes into account & radically improves every single step of the user journey. The coldest wallet generation & management.
