Proto’s mission is to accelerate the transition to a more open, equitable global economy. We believe open protocols like Bitcoin are integral to achieving that vision. The team’s first two initiatives—mining tools and a self-custody wallet, Bitkey—aim to decentralize access for builders, increase network resiliency, and make everyday use of bitcoin safe and easy. One principle across everything we do in Proto is open development – show and tell. We develop products in the open, you can read more about them at bitkey.build and mining.build.
