The key starts inside
During setup the chip creates the private key. You do not type that key in from a laptop, and the laptop does not keep a copy for later.
Hardware wallet
Novubase is a hardware wallet from Infinite Business & Event Solutions, Inc. in Cypress, Texas. It is a physical device that holds the private keys for cryptocurrency. The key is created on a chip, and the request is read on the device’s own round screen.
The object
Novubase is a rounded square you can cover with a palm. Under the ceramic face sits a security chip. The round display above it has one job: show what that chip wants you to read. The computer on the other end of the cable does not paint those pixels.
There is no battery to charge and no wireless radio to join. The device wakes from the USB-C cable and goes quiet when the cable leaves.
Why it is built this way
During setup the chip creates the private key. You do not type that key in from a laptop, and the laptop does not keep a copy for later.
A request that arrives over the cable is drawn by the chip onto the round glass. If the words on that glass are wrong, the buttons stay untouched.
Setup shows a 24-word recovery phrase on the device. You write it by hand and keep the paper away from the computer. Novubase will not ask you to read those words aloud.
A session
A reader on the computer prepares a request. Novubase does the rest where you can see it.
The reader cannot finish the request on its own. It can only pass the details to the device.
Amount, destination, and any warning the chip cares about appear on the glass. That view is the one that counts.
The right button tells the chip to sign. The left button declines. Without that press, the signature stays inside the case.
On the desk
Novubase sits closed. The screen is dark, the buttons do nothing, and the chip is unpowered. A session begins when USB-C connects and ends when it does not.
First group
Novubase is calling a first group of readers. A name and an email are enough. Three notes come back with that place.
