Most efforts haven't moved beyond the planning stages. Just because you can point to a plugin or a FEP spec doesn't mean that it's an ongoing active effort for bring a payment layer to the Fediverse, with a consumer-facing tool or platform. I'm sorry if I didn't catch that Mitra had some of that functionality, but I would also push back and say that the average person is not going to use Monero for payments on the Web anytime soon.

Those PeerTube plugins are nice, and the Premium Users one was actually something I pointed @quillmatiq@mastodon.social to for sub.club, as an example of prior art. They're interesting experiments, possibly useful integrations, but not in and of themselves actual platforms to build infrastructure and solutions on.
