General-purpose computers (smartphones, laptops, smartwatches...) are insecure by design.
This is because they are connected to the internet and have an infinite number of use cases.
Anyone can write programs for them and distribute these programs globally over the internet.

The problem is that the programs can contain commands that don't have your best interests at heart.
Malicious programs, viruses, or simply hacks, are downloaded either accidentally by the user or remotely by a hacker.
They can steal your digital identity and property, which is at this point basically everything you own.

The incentive for cybercriminals is mostly financial. The North Korean nuclear program, for example, is funded with cybercrime. This is why we need a new approach to cybersecurity!
Anti-virus software and security chips help treat the symptoms, but don't solve the root problem.
The root problem is that our keys (passwords) are stored on vulnerable general purpose computers.

CLAVIS is the solution to this problem!
It's a hardware wallet, a digital master key, used to generate, store and sign with your private keys (passwords), completely offline.
