Bitcoin Magazine Blockstream Launches Jade Core to Simplify Bitcoin Self-Custody Without Sacrificing Security Blockstream has introduced Jade Core, a new hardware wallet designed to expand access to Bitcoin self-custody through a simplified user experience.

Jade Core addresses this gap through guided onboarding and tighter integration with Blockstream’s mobile and desktop applications. The device supports Bluetooth pairing and enables users to manage transactions across platforms without relying on custodial services.
