Help wanted with payment frontend and backend

I know some subscribers might have wanted to help with development but didn't have the right tech stack. Fortunately, AI now helps reasonably well when venturing into unfamiliar territory, and this task is a little different. It's for the project as a whole, but its connection to the game is financial. We need a frontend and backend to receive and account for payments. The transaction provider will be one of the global platforms that do this sort of thing, such as Braintree. So if you'd like to help with that, I'd gladly accept the help! Otherwise, I'll do it all myself, as usual.
