Esusu — rotating savings circles on Creditcoin

A Gluwa project.

Traditional esusu/ajo savings circles as a self-contained smart contract on Creditcoin Testnet, plus a fully client-side dApp. Every contribution, miss, cure and payout becomes a permanent, portable on-chain record — the raw material for Creditcoin's credit-history thesis.

Quick start

# contracts (deps are git submodule-free here — install them)
cd contracts && forge install OpenZeppelin/openzeppelin-contracts@v5.6.1 foundry-rs/forge-std@v1.16.2 && forge test

# dApp
cd fe && npm install && npm run dev

Testnet demo — tokens have no value. Circles need 3–12 members; misses are curable; an uncured miss forfeits your own pot. See contracts/README.md for the full trust model.
