fwiw Open Collective still manages crypto funds/grants for projects, I just saw this recently: https://blog.orhun.dev/open-source-funding-with-ratatui/ the Ratatui project set up a Open Collective to handle donations from the "DRIPS network" crypto
edit: also just looked more at the blog's site and at the donation page Crypto
only has Monero ;) https://donate.orhun.dev/ love it @[email protected] !
