Hey everyone! This is the Blockstream Jade team and we’re here to answer questions about the latest firmware upgrade that brings air-gapped transaction capability to Jade.
Blockstream Jade’s camera has been dormant since its release in early 2021, but firmware version 0.1.41 brings some powerful new functionality to Jade by fully enabling the camera for use. Jade users can now access their device and communicate with companion apps solely using QR codes - no USB or Bluetooth required. This includes importing a wallet, verifying receive addresses, and signing bitcoin transactions.
Jade has become even more versatile with this upgrade, specifically by allowing for additional compatibility with mobile wallet apps such as BlueWallet and Nunchuk. However Jade can also now be used in an air-gapped manner with popular desktop apps, such as Sparrow and Specter.
We hope everyone enjoys this feature as much as we’ve enjoyed building it. AMA!
