Paste in cashu token from clipboard and done, no?
Discussion
You’re not wrong
It just limits usage to people who have cashu
I’m all for accepting cashu, but I don’t know if I would restrict it to exclusively cashu
It's pretty accessible though. Anyone without cashu can just go to cashu.me, go through the flow there, then add in some Sats from their LN wallet, all in a minute or so.

Or integrate cashu.me directly in to the site, like https://iris.to/wallet has.
