[The transcript from the YouTube video follows, illustrating the step-by-step process of sending a transaction with Blockstream Jade and a Nunchuk.]
– Sending Air-Gapped Transactions with Blockstream Jade: A New Way to Access Your Wallet
Now, instead of signing transactions via USB, we can utilize Blockstream Jade’s QR code feature to access our wallet and send air-gapped transactions. To begin, I’ll scan the QR template on my Jade device by entering QR mode and selecting “scan seed QR.” Once scanned, I will no longer need the template.
On my mobile phone, I’ll open Blockstream Green and navigate to the “receive” section. There, I will copy the provided address. Next, I’ll switch to my nunchuck wallet, to which I have transferred some funds. From the nunchuck wallet, I’ll select “send” and choose to send all the funds to my Blockstream Green wallet. I’ll input the address copied from Blockstream Green and click “create transaction.”
Now that the transaction is created, I need to sign it with my Blockstream Jade. I’ll select “sign” on the Jade device and choose “export transaction” followed by “export via QR.” Moving back to my Jade device, I’ll open the camera and scan the QR code of the transaction. The Jade device will display the address copied from Blockstream Green and the amount of SATs I’m sending to the wallet. If everything looks good, I’ll press the checkmark.
The Jade device will then show the transaction fees, and if I approve, I can press the checkmark to continue. The Jade device will generate its own QR code. I must import this QR code into my nunchuck wallet. To do so, I’ll place the Jade device down and select “import signature” on the nunchuck wallet. I’ll scan the Jade device using my phone, and the nunchuck wallet will indicate that the transaction has been signed and is awaiting broadcasting to the Bitcoin blockchain. If all is well, I’ll press “broadcast transaction,” and just like that, my first air-gapped transaction using the Jade wallet is sent.
– Simplifying Transaction Signing: Using QR Codes instead of USB
In this post section, we will explore the use of QR codes as a simplified method for transaction signing, eliminating the need for USB connections. By leveraging QR codes, users can easily access their wallets and complete transactions on desktop or mobile devices.
To begin the process, the user scans a QR template using their Jade wallet. This template is created earlier and serves as the link between the wallet and the transaction. Once scanned, the user can proceed to grab their template and move it aside.
On the mobile phone, the user opens the Blockstream Green wallet and selects the “receive” option. They then copy the provided address. Switching to the Nunchuck wallet, which contains the funds, the user selects “send” and proceeds to send the desired amount to the Blockstream Green address. Pressing “send all” ensures the entirety of the wallet balance is transferred.
After successfully creating the transaction, the user needs to sign it using the Blockstream Jade wallet. By selecting “sign” and then “export transaction via QR,” the user generates a QR code representing the transaction. This QR code is then scanned by the Jade wallet, displaying the recipient address and the amount to be sent. Upon verifying the details, the user can proceed by confirming the transaction fees and pressing the check mark.
At this point, the Jade wallet generates its own QR code, which needs to be imported into the Nunchuck wallet. By scanning the Jade with the phone, the Nunchuck wallet recognizes that the transaction has been signed and awaits confirmation to broadcast it on the Bitcoin blockchain. Once the user verifies all the details, they can press “broadcast transaction,” completing the process.
With the use of QR codes, the transaction signing process becomes simplified and removes the dependency on USB connections. Users can securely and conveniently complete transactions by leveraging the camera capabilities of their devices.

– Enhancing Security and Efficiency: Leveraging Blockstream Jade and Nunchuk Wallet to Send Transactions
In order to enhance security and efficiency, we can leverage Blockstream Jade and Nunchuk Wallet to send transactions. Instead of signing the transaction via USB, we will be using a QR code to access our wallet. To do this, we can scan the QR template that we previously created using the QR mode on the Jade. Once scanned, we can then proceed to grab the template and set it aside.
On our mobile phone, we can open Blockstream Green and navigate to the receive option. From there, we can copy the address provided by Blockstream and switch over to the Nunchuk Wallet. In the Nunchuk Wallet, we can choose a wallet that contains the funds we want to send, then press send. We can select to send all of the funds from that wallet and input the address from Blockstream Green. After creating the transaction, we need to sign it on our Blockstream Jade. To do this, we can press sign and then export the transaction via QR. We can then use the Jade’s camera to scan the QR code displayed on the Nunchuk wallet.
Upon scanning, the Jade will show us the address copied over from Blockstream Green along with the amount of SATs we are going to send. If everything looks good, we can proceed by pressing the check mark. The Jade will then display the fees we will pay, and if acceptable, we can press the check mark again. We now need to import this signed transaction into the Nunchuk wallet. To do this, we can put the Jade down and press import signature on the Nunchuk. Using our phone, we can scan the Jade, and once the progress bar is complete, the Nunchuk wallet will confirm that we have signed the transaction. We just need to broadcast this transaction to the Bitcoin blockchain by pressing the broadcast transaction button. And just like that, we have successfully sent our first transaction from the Jade wallet by signing a partially signed transaction via QR code. This method allows for enhanced security and efficiency in sending transactions. In conclusion, the YouTube video titled “Sending Air-Gapped Transactions from Nunchuk with Blockstream Jade” demonstrated an innovative method of conducting transactions using an air-gapped device. By utilizing a QR code, the video showcased how to securely transfer funds from a wallet on the Nunchuk to the Blockstream Green wallet on a desktop or mobile phone.
The process began by scanning a QR template on the Jade device, which prompted the camera to capture the seed QR. After scanning, the template was no longer needed. On the mobile phone, the Blockstream Green wallet was accessed, and the address to receive funds was copied. Then, on the Nunchuk wallet, the desired funds were sent to the Blockstream Green wallet by pressing the “send all” option and inputting the Blockstream Green address. A transaction was created, but signing the transaction was necessary.
To sign the transaction, the user selected the “sign” option on the Blockstream Jade device and exported the transaction via QR code. Using the QR scan function on the Jade, the transaction was scanned successfully, showing the address copied from Blockstream Green and the amount of SATs to be sent. If everything appeared correct, the user pressed the check mark and reviewed the fees. Upon confirmation, the Jade displayed its own QR codes, which needed to be imported into the Nunchuk wallet.
By scanning the Jade with the phone, the signature import process was completed, indicating that the transaction had been signed. The final step involved broadcasting the transaction to the Bitcoin blockchain. If all was in order, the user could press the “broadcast transaction” option, successfully sending their first transaction from the Jade wallet.
Through this creative method of using QR codes and an air-gapped device, the video demonstrated a secure and efficient way to conduct transactions. It showcased the possibilities of leveraging technology for enhanced privacy and control over digital assets. By following the steps outlined in the video, users can confidently navigate the process of sending air-gapped transactions with the Blockstream Jade device.
