I currently use https://tipcards.io/ for convinience.

It does a good job of teaching people how to use WOS, and works great.

It's not so good for the other stuff you mentioned,

I forked the project, a while back to address some of these concerns, but I got busy.

The more I think about it, we could attach a QR code that links to a nostree.me instance that provides this information.

Another option(I haven't tried yet) is to leave a Mutiny Wallet Gift, but I think the minimum is 50k sats. I like the self-custodial aspect, but it's not the best UX for someone who is not all interested in bitcoin to begn with. I might leave one of these on a car by my house that has a shibu inu bumper sticker though, just to show him there's a better option than some BS eth token that makes absolutely no sense. 😂
