Also lemmy.world is extremely slow in pushing out messages to other instances, if at all. So leading the pack is not necessarily the best thing until you figure out scaling.

I have seen https://opencollective.com/ used a lot to collect donations in a transparent way (also supporting crypto payments). Maybe that is something you want to look into as well.

The thing is, the "software" actually is open source, so you can tell how data is requested from your smart ID. The german government ID has an explicit function for age verification that does not provide any personal information.

However it is probably hard and costly to get certified to use any of those functions as a service provider.
