Mifi Core
Core banking and microfinance platform for the CEMAC region. Double-entry ledger, teller back-office, customer mobile app, and offline branch support.
About This Product
Mifi is a full core banking system built for microfinance institutions and credit unions operating in the CEMAC region (XAF), engineered toward COBAC regulatory requirements. At its heart is a double-entry, append-only ledger written in Rust, where every transaction is balanced against system vault accounts and verified daily by an automated end-of-day process. The platform ships as a complete suite: a multilingual back-office for admins, branch managers, and tellers; a Flutter mobile app for customers with transfers, savings goals, and loans; mobile money deposits and withdrawals via MTN and Orange Money; and Mifi Edge - lightweight branch nodes that keep rural branches transacting through internet outages and sync back idempotently when connectivity returns.
- Double-entry ledger with exact decimal arithmetic - no floating-point money anywhere
- Append-only transaction history enforced by database triggers, with hash-chained audit logs
- Maker-checker (four-eyes) approval flow for high-value operations
- Idempotency keys and database constraints on every money-moving endpoint
- Customer PII encrypted at rest with keyed blind indexes for duplicate detection
- Mobile money integration with webhook signature verification and automated reconciliation
- Mifi Edge: offline branch nodes with zero-double-spend sync for rural connectivity gaps
- Automated end-of-day: daily interest accrual (Act/365), KYC aging, and system reconciliation snapshots
- Role-based access control (SuperAdmin, Branch Manager, Teller, Customer) with Argon2id-hashed credentials and transaction PINs
- Multilingual back-office and mobile app (French, English, Spanish)
