Afribit ( https://geyser.fund/project/afribitkibera ), for example, not one gets merchants signed up, and wallets in the hands of the community, but also helps fund some needed services. The absence of structured waste disposal in much of Kenya has led to widespread normalization of littering -- particularly so in the slums. Afribit pays (in sats) for workers to collect trash from the streets, gutters, and some collection points, and also helps to educate as to why littering harms the community.

As far as questions or feedback, I don't think @geyserfund itself has that, at least not beyond you being able to add a comment when contributing. You could include your contact info, to hopefully permit a direct response.
