Desktop Lightning and QR Signing Reach Blockstream App
Blockstream App 3.5.0 for desktop adds Lightning payments in beta and expands Jade hardware wallet workflows built around QR codes. The release lets eligible software wallet users send and receive bitcoin over Lightning from inside the desktop app, while Jade users gain QR-based connection, unlocking and air-gapped signing for descriptor-based watch-only wallets. Blockstream also says new Bitcoin and Liquid swaps are temporarily disabled because of a service interruption, although existing funds are unaffected. The update is live for macOS, Windows and Linux, followed by a 3.5.1 patch with stability fixes.Desktop Lightning arrives in beta
Blockstream says version 3.5.0 brings Lightning payments to its desktop app in beta, allowing users to send and receive bitcoin over the Lightning Network without leaving the wallet interface. The feature is enabled from wallet settings, after which the app adds dedicated Lightning send and receive pages.The supported scope is narrower than the headline may suggest. Blockstream says Lightning support is available for software wallets on Bitcoin mainnet and excludes BIP39 wallets. That means the feature is not presented as universal across every wallet configuration in the app.
For users who fit the supported setup, the practical change is operational simplicity. The source states that there is nothing else to install and no separate node software to manage, so the desktop app becomes the place where the Lightning payment flow is initiated and handled. Since the feature is still labeled beta, cautious users should treat it as an early implementation rather than a settled default for all wallet types.
Jade QR Connect reduces reliance on cables and Bluetooth
The second major change is QR-based access for Jade. Blockstream describes Jade QR Mode as a way for the desktop app to connect to and unlock a Jade hardware wallet through QR codes exchanged between the computer screen and Jade's camera.The company contrasts this with plugging in a USB cable or pairing over Bluetooth. In the new flow, the user scans a short series of codes and the device unlocks without a physical connection between the keys and an online machine, according to Blockstream.
The security implication is specific and limited. QR Connect does not remove the need to verify what is being signed, nor does the source claim it eliminates every possible risk in wallet operation. It does, however, give users a connection method that avoids USB and Bluetooth for the supported Jade workflow, which may be useful for people who prefer tighter separation between a hardware signing device and an internet-connected desktop.
Watch-only wallets gain an air-gapped spend path
Blockstream says descriptor-based watch-only wallets on desktop now support air-gapped signing with Jade. A watch-only wallet can be used in the app to track balances and generate receive addresses, while the Jade device remains powered off until a spend is needed.When spending, the transaction is built in the desktop app and signed with Jade over QR codes. Blockstream frames the combined QR Connect and watch-only signing flow as a fully air-gapped workflow from setup to spend, with private keys not touching an internet-connected machine.
This is the most consequential part of the release for users who separate monitoring from signing. A watch-only desktop wallet can remain convenient for balance checks and address generation, while transaction authorization stays on the hardware device. The feature is still bounded by Blockstream's stated support: it applies to descriptor-based watch-only wallets using Jade in the desktop app.
Temporary swap limits and smaller workflow fixes
The release also includes a notable limitation. Blockstream says new swaps between Bitcoin and Liquid, including Liquid Bitcoin via Lightning, are temporarily disabled in version 3.5.0 because of a service interruption. The company adds that existing funds are unaffected.That distinction matters for readers assessing the release. The Lightning beta and Jade QR workflows are being introduced, but one related swap function is paused. The source does not provide a restoration time in the supplied material, so any estimate about when swaps return would be unsupported.
Blockstream also lists smaller usability and platform changes. The receive flow now auto-selects the asset and account, transaction completed and failed pages have been updated, Windows wallet libraries are code signed, and architecture-specific macOS disk images are thinned to their native architecture while a universal image remains available. Legacy multisig nLockTime and recovery email flows are also back for wallets that rely on them.
Why the release matters for desktop bitcoin users
The update points to a desktop wallet strategy built around two ideas: integrated Lightning payments and more isolated hardware signing. Those are different goals, but both affect how users move between convenience and key separation.The Lightning beta reduces the number of tools an eligible user needs to manage for basic Lightning sends and receives. The Jade QR additions move in the other direction by keeping signing activity away from direct USB or Bluetooth links and by supporting watch-only monitoring on the connected machine.
Readers should keep the source of the claims in view. The evidence comes from Blockstream's own release post, not an independent audit or third-party performance review. The confirmed facts are the stated feature set, supported wallet scope, temporary swap interruption, platform availability and listed patch status. Claims about long-term reliability, user adoption or comparative security against other wallet products are not established by the supplied source.
Conclusion
Blockstream App 3.5.0 is a meaningful desktop wallet update because it combines a beta Lightning payment path with a broader QR-based Jade signing workflow. The release gives eligible Bitcoin mainnet software wallets in-app Lightning send and receive pages, while descriptor-based watch-only wallets can now use Jade for QR-signed transactions.The update is not a blanket expansion to every wallet type, and the temporary suspension of new Bitcoin and Liquid swaps is a clear operational caveat. For users already inside the Blockstream desktop and Jade ecosystem, the release adds convenience at the payment layer and more separation at the signing layer.
