Block (NYSE: XYZ) introduced a series of bitcoin-focused products and features aimed at strengthening its position across custody, payments, and financial infrastructure. The announcements include a new Bitkey hardware wallet with a built-in screen, expanded bitcoin earning tools within Cash App, a Proof of Reserves system, and a forthcoming Square tap-to-pay experience for bitcoin transactions.
The updated Bitkey hardware wallet marks a shift in how users interact with self-custody. The device has a secure touchscreen that serves as the verification layer for transactions and security settings.

Block said via a note shared with Bitcoin Magazinethat they designed the interface to address risks tied to external devices, where users often rely on separate systems to manage wallet permissions. By integrating transaction approval and security controls into the hardware, Bitkey aims to give users full control over both funds and system integrity.

Bitkey continues to operate on a 2-of-3 multisignature model and removes the need for seed phrases. The product also includes inheritance features and a privacy-focused design. Block opened preorders for the device and released a technical document outlining its framework across security, recovery, privacy, and usability.
