Example:
In Kilifi, a school, a grocer, and a community clinic each list what they offer as ERC-20 vouchers: tuition & meals (SCHOOL), staples by weight (FOOD), and consultations & meds (CARE). They stake a seed of their own vouchers into the Kilifi Bio-Region Commitment Pool and set what they’ll accept in return (cUSD and selected local vouchers).
- A parent pays part of school fees by swapping FOOD → SCHOOL through the pool: the grocer’s voucher routes to the school, the school voucher goes to the parent.
- The school then uses some of its SCHOOL vouchers to swap for CARE (school health day at the clinic).
- The clinic swaps CARE for FOOD to restock its nutrition program.
- A repair co-op joins later, issuing REPAIR vouchers; the clinic swaps CARE → REPAIR to fix equipment, and the co-op takes FOOD for wages.
Everything is discoverable by GPS in the wallet, so neighbors see nearby offerings and prices. Every mint, swap, and redemption is on Celo, creating interest-free, in-kind credit that circulates locally (voucher replacing voucher) while the pool’s tiny swap fee funds dashboards/oracles for community reporting.
