The Bitkey beta is a bitcoin wallet developed by Block, a FinTech company backed by Jack Dorsey. It is designed to provide users with a safe and easy way to own and manage bitcoin. The beta version of Bitkey includes a mobile app, a multi-signature hardware wallet device, and a set of recovery tools . In the Bitkey beta feature set, users can add, send, and receive bitcoin via the Bitcoin blockchain network. This allows them to reliably send and receive bitcoin around the world using just their mobile phone or their hardware wallet for added protection. The beta version also includes recovery tools to help users recover their bitcoin in case they get a new phone or lose their hardware . The Bitkey beta program was open to bitcoin holders around the world, who could apply to join the beta testing program. Selected participants received a free Bitkey hardware device to try out the product and provide feedback to help shape its development .
