Bitcoin has grown in value over the last decade, and with that growth in value comes much-needed security. It was fine to keep bitcoin on your laptop or USB drive when it was worth a few bucks, but when you’re dealing with hundreds, thousands and even millions, you’ll need a better storage solution.
As the need for securing your digital value increases, plenty of manufacturers have sprung up to offer their version of a hardware signing device. These devices have helped push the self-custody movement forward and become an integral part of any bitcoiners journey.
While healthy competition helps drive improvements in signer device technology, they don’t have a monopoly on this market. Bitcoin is an open-source movement, so if you don’t like the offerings available, want to improve on it, or build from source, you’re welcome to do so with a DIY bitcoin key signing device.
What hardware do I need?
It all depends on the project, your level of complexity and the access to parts you have available. Creating a hardware storage solution can be as low-tech as using a USB drive with enough space to run the software, or you can build out something more robust using a raspberry pi and some additional components.
What software do i need?
There are several projects currently running that offer up their code on open source platforms, and you can download and run this software on compatible hardware devices you’ve set up.
If you would like to get involved in building your own hardware signing device, then check out some of the projects below for detailed buying guides, tutorials and support for your build.
