CrowdBucks is a new payment system for the Fediverse

This was initially demoed at FediCon 2025, but CrowdBucks is an open source, self-hostable fundraising system that allows people to financially support one another. You use your existing Fediverse account to hold a fundraiser, and can also donate to other people's fundraisers as well. The form factor is kind of similar to Kickstarter or Patreon.
