Blockstream Launches Jade Core to Simplify Bitcoin Self-Custody Without Sacrificing Security

Bitcoin Magazine

Blockstream has introduced Jade Core, a new hardware wallet designed to expand access to Bitcoin self-custody through a simplified user experience. 

The device builds on the company’s existing Jade lineup and retains its open-source security model while targeting a broader base of users.

The launch reflects a shift in hardware wallet design as providers seek to reduce barriers tied to self-custody. Many existing solutions have focused on experienced users, with complex setup processes and technical requirements. 

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. Private keys remain stored on the device, and all transaction signing occurs offline. This architecture reduces exposure to online threats while preserving user control over assets.

Jade Core includes several core security features tied to Blockstream’s existing framework. These include open-source hardware and firmware, allowing users and developers to audit the system. The device also incorporates Blind Oracle PIN protection, which uses encrypted authentication to guard against unauthorized access, including cases involving physical compromise.

Users can verify device authenticity during setup, a feature designed to address supply chain risks in hardware wallets. The device display has been updated to support clearer transaction verification, reducing the risk of user error during transfers.

Blockstream said Jade Core is part of their broader effort to expand direct ownership of Bitcoin. The company has emphasized counterparty risk tied to centralized exchanges, particularly following a series of failures and security incidents across the digital asset sector. Hardware wallets have gained traction as users seek greater control over funds.

Blockstream: Retail-facing tools, institutional rails

According to Blockstream executives, Jade Core aligns with a wider product strategy that connects retail-facing tools with institutional infrastructure. The company aims to support both individual users and larger market participants through a unified ecosystem built on Bitcoin-native technology.

The release comes at a time when demand for self-custody solutions continues to grow alongside Bitcoin adoption. By reducing complexity without altering core security assumptions, Blockstream is positioning Jade Core as an entry point for users transitioning away from custodial platforms.

Jade Core expands competition in the hardware wallet market, where usability and security remain key differentiators. As adoption increases, providers face pressure to deliver tools that balance ease of use with strong protections tied to open and verifiable systems.
