I built one of these for phantom and Solana. the problem is there are just too many steps involved with building the page, and then it's too slow. I wanted to replace online display ads with a JavaScript widget that would charge you 3 cents as you scroll down the page, or have the "more inside" button charge users 3 cents or whatever. Didn't get to that part, but everything was just so clunky that it only really worked as a tech demo.
The problem is that crypto people already know crypto and have a wallet. It's the people that don't know crypto and are repulsed by it that you have to convince that hey, here's a valid use case for crypto (micropayments) but you have to do all this work before you can use it, and while the rails are there, it's just too immature.
