The sensor will analyze several signals from your body (movement, sweating, etc.), Developing a specific identifier in which the personal seed of the hardware wallet will be encrypted. If someone steals your device, he will not be able to access any of the tools, because the sensor will reject his body. This innovation can change people's view of cryptorics.
That's a really great feature, as safety always matters! And despite this, there are a lot of features they are implementing, I mean new and modern ones. For example, Ghost Mode. It is about that you can completely hide the blockchain features keeping everything away from peeking eyes. As for me, project really worth realization!

And team is incredible
Talking about features, we should definitely mention security. And Sidera is really advanced in here. If somebody stoles your device he won't manage to access any funds because the sensor will reject his body!
