Cold computer setup

Your offline computer/laptop will be signing all of the transactions. It should always be kept offline i.e cold. It can not be used for other tasks.

I highly recommend that you use a linux distribution and NOT windows for cold storage. Linux is free and opensource. I highly recommend pepermintOS or MX linux as they are lightweight and pretty easy to setup.

I will not be guiding you on how to install linux. But here are some resourses to help you get started:

Downloading & Installing necessary software

The first thing that we will need to do is download the required software.

We will need featherwallet

and that’s about it.

Taking the device offline

It is highly recommended that you disable the wifi and bluetooth modules on your cold computer. This can be by physically detaching the wifi and bluetooth module or disabling it in the bios. The later is less secure if you’re going full on tinfoilhat.
