A complete multi-tenant banking back end and customer app. Customers and administrators use one interface and every rule is enforced on the server.

Balances are never stored: each balance is the sum of its postings, and journal entries are append-only, protected by database triggers. A nightly integrity check proves the books balance.

What is simulated in the box: FX rates, crypto custody, stocks, cards and settlement rails. Going live with real money needs licensed partners that you connect through the provided interfaces. This software does not make you a licensed bank.
