Blockstream Jade Adds Lightning Interaction From Cold Storage
Blockstream updated Jade and the Blockstream app so users could send and receive Lightning payments while keeping signing keys on a hardware wallet. The design used Lightning-to-Liquid swaps to bridge fast payments with offline cold-storage security.
On March 12, 2026, Blockstream announced Lightning payment interaction for its Jade hardware wallet through version 5.2.0 of the Blockstream app. Blockstream described Jade as the first hardware wallet able to interact with Lightning while keeping the user's signing environment in cold storage.
The implementation did not turn the hardware wallet itself into a conventional always-online Lightning node. Instead, the app used its existing Lightning-to-Liquid swap infrastructure so a user could send or receive Lightning payments while maintaining the security model of hardware-backed keys.
The release addressed a longstanding usability tradeoff. Lightning payments are designed for speed and frequent interaction, while hardware wallets are designed to isolate keys from internet-connected devices. Joining those two workflows in a consumer product widened the design space for self-custodial Lightning use and made the event more significant than a routine wallet feature update.
