In order to sign transactions using QR Scan, you will first need to export your wallet's xpub to a QR compatible wallet platform. This piece of information allows your companion device generate receive addresses and create PSBTs for Jade to sign. Tip: You can also use these instructions to set up a watch-only wallet for your Jade on your preferred wallet app. Export Xpub 1. Unlock Blockstream Jade using your preferred method (ideally by using QR Mode for air-gap users). 2. Select Options, then choose Wallet and navigate to Xpub Export. 3. You will then see a QR code displayed which contains the xpub for the derivation path shown. The default path is m/84'/0'/0', which is used for singlesig, Native SegWit wallets. If you would like, you may change this path to Nested SegWit (m/49'/0'/0') by selecting Options. Warning: Make sure to select the matching script type on your compatible wallet app, i.e. Native SegWit for m/84' and Nested SegWit for m/49'. The wrong wallet will be generated if you do not choose the correct option. View our xpub settings guide for more info. 4. Next, scan the xpub QR code with your compatible wallet app. Once it is successfully read, your wallet should be added and you may use this platform to generate receive addresses and create PSBTs for Jade to scan and sign.
