Block, a fintech company led by Jack Dorsey, has announced the pre-order availability of its self-custody bitcoin wallet, Bitkey, in over 95 countries. Bitkey comprises a mobile app, hardware device, and recovery tools, with the app enabling customers to make bitcoin transactions through their mobile phones and the hardware device storing their assets offline. Bitkey's third key is stored on the company's servers and is used to verify transactions made by customers using only their phone and to recover their wallet if they lose their phone or device. The wallet is expected to be shipped in early 2024, and it will connect to Block's payments platform Cash App and crypto exchange Coinbase to facilitate buying and selling of BTC within the app.
