Community AI for school co-ops

The money of a school co-op, in the open, with a robot that never spends alone.

Today one or two volunteers handle it with cash, a bank account and a spreadsheet. Minga is a treasurer that lives in Telegram: families contribute from a chat, bills get paid by rule, big ones wait for signatures, and every peso is public.

How Minga works

1FamiliesChip in from the chatAny amount, in pesos. A receipt in a minute.
2The contractHolds the moneyNot in anyone's account. Readable by anyone.
3The boardSends an invoice photoNobody on the board touches the money.
4The robotChecks four rulesCap per payment, room in the line, vendor cap, balance.
Fits: paid nowThe vendor gets it on the spot.
Too big: 2 signersApproved with a fingerprint, or never paid.
5EveryoneSees it on the ledgerEvery invoice, plus a monthly report the auditor signs off.

Celo + wARS: · pesos on chain, no gas to think about
Policy contract: · holds the funds, enforces every rule
Passkeys: · a fingerprint instead of a seed phrase
ERC-8004 agent: · an identity anyone can check

Will the robot pay it?

Every bill goes through the same four checks in the contract. Move the amount and see which one stops it.

Budget lineVendor

The robot pays it on the spot.

All four checks pass, so the contract lets the agent pay. The auditor is told as it happens.

And no matter the amount, it can never

pay a vendor that's not on the list
change budgets, caps or signers alone
pay itself
keep paying after a pause
