A savings circle that runs itself: shares stream by the second into a pot that pays whoever's turn it is.
Eight people, fifty dollars a week. Each keeps a jar, their share streams out by the second, the pot fills in public and pays out the moment the round closes. Gaps stay on the record.
Give every savings circle a pot that pays on time and a record everyone can trust, so the banker never has to chase or cover again.
Hundreds of millions of people save through rotating circles (pardna, susu, esusu, tanda, chit funds). They run on trust and one tired banker with an exercise book: cash in envelopes, chasing late members, covering gaps from their own purse, and no shared record when memories differ.
Everyone stakes a conviction, encrypted. The chain tallies it without ever seeing a single take. FHE on Base.
Governance by text-sized questions: one decision a week, answered in ten seconds, with real quorum.
Crowdfunding where backers get refunded by contract if the goal or the milestones are missed.
A shared house or club tracks who did the work, and the record becomes everyone's portable reliability score.
Lend the ladder, the drill, the tent: a street library of things with deposits held by contract.
Fund a public good with hours of your skill, not just money, and get matched like a donation.
A rotating savings circle (ajo, susu, chama) with payouts enforced by contract and trust scores for members.
Retro funding for the quiet helpers: the community nominates who mattered, a pot pays them.
