Blockstream Jade's QR Scan functionality allows it to be used with BlueWallet, a popular mobile bitcoin application. BlueWallet offers a simple interface while also providing the option for advanced features.
Pre-Requisites
1.
Prepare Jade for QR Mode.
Setup Wallet
Your Jade will need to be set up for watch-only functionality with BlueWallet first, in order to receive bitcoin and create transactions for Jade to sign. This process only needs to be done once for each device you use Jade as a signer on.
1.
Unlock Blockstream Jade, ideally by accessing QR mode.
2.
Navigate to Options, Wallet and select Xpub Export. Jade will then display your xpub as an animated QR code.
Warning: It is not recommended to change the default settings unless you are absolutely certain of the implications of selecting Wrapped Segwit or Multisig - as this may cause you to create the incorrect wallet.
3.
Open BlueWallet and choose to Add a Wallet, then select Import Wallet.
4.
Scan the animated QR code shown on Jade using BlueWallet. BlueWallet will show a progress indicator and will proceed automatically once it has read every frame. Your wallet will then be successfully added.
Receive Bitcoin
1.
Select your newly created watch-only wallet and tap Receive.
2.
Navigate to QR Scan on Blockstream Jade and point Jade's camera at your bitcoin address QR code.
3.
Once the address is recognized by Jade, confirm it matches the address shown on BlueWallet and select Yes to continue. Jade will check if the address does indeed belong to your wallet.
4.
After the address is verified, share it with the sender to receive your funds.
Note: If Jade is unable to verify your address, this does not necessarily mean there is malicious activity involved. Make sure to review our full address verification guide for more tips on how this process works and common troubleshooting steps.
Send Bitcoin
1.
Select your wallet and tap Send. Enter the recipient's address and amount, then choose Next to display the PSBT as an animated QR code.
2.
Select QR Scan on your Blockstream Jade and point the camera at the QR PSBT. If the QR code is animated, Jade will need to capture every frame that is displayed to continue.
Tip: The progress bar will fill up as you successfully scan new frames. If the progress bar is not updating, change Jade's angle or distance from the QR until you find the optimal placement for scanning. View more scanning tips here.
3.
Once Jade has successfully read the PSBT, it will display the transaction details on your device for you to review and confirm.
4.
Jade will then display your signed transaction as a series of QR codes. Scan Jade's screen with BlueWallet until all frames have been captured.
5.
After BlueWallet has successfully scanned the signed transaction, select Send Now to broadcast it to the network and your bitcoin will be sent.
