In order to send bitcoin with your air-gapped Jade Plus, you will need to create a transaction using a companion app and pass the information to Jade Plus using QR codes for authorization (or "signing"). After signing the transaction, Jade Plus will display this information back as animated QR codes for your companion app to scan so that it can be broadcast to the Bitcoin network.
Note: This guide demonstrates air-gapped use with Sparrow. Please refer to your wallet app's specific instructions if not using this companion app.
1.
Open your QR-compatible companion app and create a new transaction by entering the recipient's address and the intended amount to send.
2.
Choose to show your unsigned transaction in a QR code format, then start an air-gapped Jade Plus session and select Scan QR. Point the camera at the animated QR code until the progress bar is filled.
Tip: Lower the QR density on your companion app if you are having trouble reading the QRs.
3.
Confirm on Jade Plus that both the address and the amount match what you intended. Select the checkmark when you are ready and the signed transaction will be displayed as an animated QR code on Jade Plus. Choose to scan the QR on your companion app, scan the animated QR display until the progress bar is full, then broadcast the transaction to finish sending.
Tip: Click Options on Jade Plus and lower the density or frame rate settings if your app is having trouble scanning the QRs.
