Kumbara is a flexible micro-savings dApp on Celo Mainnet. Users create personal or group piggy banks and deposit/withdraw cUSD or USDC anytime, with no lock-up period. Each user's balance is tracked separately even in shared group piggy banks, so funds never mix and no one can withdraw more than they deposited. Inspired by traditional rotating savings circles (Ajo/Esusu in Nigeria, Chama in Kenya), brought on-chain with full transparency.
To make stablecoin-based micro-savings accessible, transparent, and trustless on Celo, starting with individuals and informal savings groups who currently rely on cash or manual tracking.
Traditional savings habits are hard to sustain without structure, and group savings circles (like Ajo/Esusu in Nigeria or Chama in Kenya) rely on trust and manual tracking, which creates risk of mismanagement and disputes over who contributed what.
Kumbara brings these savings practices on-chain. Users create personal or group piggy banks and deposit/withdraw cUSD or USDC anytime, with no lock-up period. Every user's balance is tracked separately on the smart contract, even inside a shared group piggy bank, so funds never mix and no one can withdraw more than they personally deposited. This removes the trust problem entirely while keeping the flexibility of traditional savings circles.
