Your Njangi, Now On-Chain
In Cameroon, njangi and tontine circles have financed businesses, schooling, and weddings for centuries. Njangi House brings that tradition to Polygon — with MTN Mobile Money support, transparent smart contracts, and payouts directly to your MOMO number.
Built for Cameroon, Accessible to Everyone
Whether you run a susu in Douala, a tontine in Yaoundé, or a diaspora njangi connecting Cameroonians in the UK and Canada — Njangi House handles the coordination so you can focus on saving.
Dial *126#, Save XAF
No crypto wallet needed. Contribute directly via MTN Mobile Money — the oracle bridge converts your XAF to USDC on-chain automatically.
Payout to Your MOMO
When your round arrives, receive the full pooled amount directly to your MTN MOMO number. No wallet, no exchange, no friction.
Transparent On-Chain
Every contribution, payout, and member action is recorded on Polygon — visible to all members. No more manually tracked ledgers.
Earn $NKAP Rewards
On-time contributors earn 100 $NKAP tokens per payment. Hold NKAP to reduce platform fees from 0.5% to 0.1%.
Open-Source Contracts
Smart contracts use ReentrancyGuard, ECDSA oracle verification, and anti-replay protection. Audited before mainnet launch.
Diaspora-Friendly
Cameroonians abroad can contribute in USDC or GBP while family members at home receive in XAF via MOMO — no remittance queues.
The ROSCA tradition in Cameroon
Across Cameroon — from the markets of Douala to the neighbourhoods of Yaoundé — rotating savings circles (known locally as njangi, tontine, or chip) have financed everything from school fees to restaurant expansions. Circles of 10–20 members contribute weekly or monthly, and each round, one member takes the pot. Njangi House digitizes this centuries-old trust mechanism with smart contracts — while preserving the community accountability that makes it work.
