The Proto team at Block is accelerating the world’s transition to an open economy by building products that increase access and independence for all. Our Proto team is currently responsible for the development of products and services for Bitcoin Mining and Bitkey. Bitkey is a self-custody bitcoin wallet with three parts — a mobile app to make transactions easily on the phone, a hardware device to protect savings securely offline, and a set of recovery tools in case customers lose their phone, hardware, or both.
As an innovative multi-signature self-custody wallet, Bitkey provides innovative recovery tools that give customers multiple ways to recover their money, so they can take their bitcoin off exchanges and truly own and control it themselves, without the anxiety of guarding a long complex seed phrase. Bitkey provides the convenience of a mobile app, the security of hardware, and peace of mind that in case they lose something, customers can still recover their money. Find out more at bitkey.build.
