Digital asset security firm Ngrave has released more details of its fully offline hardware wallet, the Zero. As previously reported, the Zero claims to be the first hardware wallet to receive EAL7 certification — one of the highest security gradings in the world.
The Evaluation Assessment Level is graded from EAL1 to EAL7, with the latter representing the fullest battery of testing possible, including design documentation and analysis, functional, and penetration testing.
