Why the ZERO ?

Multi-currency support

ZERO Online Attack Vectors

100% Offline

The NGRAVE ZERO generates your private keys offline and never exposes them afterwards

The device is completely "air-gapped", meaning it does not rely on any kind of network connection capability (such as WiFi/Bluetooth/NFC), nor does it require USB.


Your private keys are effectively kept away from any online attack vector. 

This is as secure as it gets.
