Unlikely, I assume every invoice is generated on the fly.

No lightning address for now, but a static BIP353 username could allow some cool things for receipts. We are still building our perspective.
Give us a way to zap the barista directly to their own wallet.
I need to look ar BIP353 npw but thanks.
I have noticed some Cash App users do have a lightning address and tipping web page. We can use those to tip people.
It would be cool for a waitress to wear flare, like Jennifer Aniston in Office Space, but with a QR code with "lightningaddress:yourusername@cash.app."
I'm not sure why some people have it while others do not. I did notice that the tipping page displays the last name though. I'm a little apprehensive of that.
