In order to perform wallet functionality fully air-gapped, you will need to export the xpub from the wallet stored on Jade Plus. The xpub allows your companion app to generate receive addresses, view balances, and create transactions for Jade Plus to sign.
Note: This guide demonstrates air-gapped use with Sparrow. Please refer to your wallet app's specific instructions if not using this companion app.
Performing wallet functions fully-air gapped
1.
Start your Jade Plus session using a QR communication option, then select Options → Wallet → Export Xpub.
2.
Jade Plus will display an animated QR code that contains the xpub for the derivation path shown. The default derivation path is for Singlesig Native Segwit accounts, however users may select Options to change this to one of the paths below:
- Native Segwit | Singlesig: m/84'/0'/0'
- Wrapped Segwit | Singlesig: m/49'/0'/0'
- Native Segwit | Multisig: m/48'/0'/0'/2'
- Wrapped Segwit | Multsig: m/48'/0'/0'/1'
Note: Make sure to select the matching script and wallet type on your compatible wallet app, otherwise it may generate an incorrect account and your balance will not appear (if you have already received funds).
3.
Open your air-gap supported app and follow the instructions to add Jade Plus as a key. Scan the animated xpub QR displayed on Jade Plus with your device's camera to set up your wallet.
