How would you generate a QR code that would do the following: when scanned it would trigger a predefined sat transfer from one lightning wallet to another?
I am envisioning a parent with a chore chart that a kid can scan a QR code when the job is done triggering a transfer of a small amount of sats from the parent’s wallet to the kids wallet
Is this possible? can it be done with most wallets?
I was playing around with zeus and don’t appear to be able to get something like this
Thank you

Preprinted invoice for each chore completed?
Yeah, is that something that can easily be made?
Are there any tools that can make pre-printed (send) invoices instead of (receive) invoices?
This is a great idea! #following
I’m pretty sure it’s possible based off this image 

And don’t most lnurl invoices have a time limit too?
Perfect for getting kids to earn their chore duties on time.
Good point 🤙😁
@ZEUS is this something I’ll be able to do with zeus wallet when I’m running my own node via Zeus?
Found this but demo doesn’t seem to be working. Anyone know about this?

Nope. You need to run a lnurl W server for that.
LNURL-withdraw links do this.
Many of my Lightning wallets do… but not all of them
Can you list a couple that have that feature?
Blue, Breeze, Phoenix, Alby, WOS
I’ve played with all of them… they all seem to work well. And there are many more.
Hmm interesting I have Alby wallet and haven’t seen that ability. Can you do it from the web app?
Sorry, shouldn’t have put Alby on that list, I can’t make an invoice with Alby either. It’s connected to my Blue Wallet which can.
You can generate alby invoices on desktop 🖥 .
Are you looking for a QR code of your Alby wallet address. I find mine at
for my Alby lightning address: moritz@getalby.com

Thank you for your response, I’m actually looking for something similar to a bitcoin voucher that would allow the person who scans the QR code to gain a certain amount of funds that were provided ahead of time.
