Frequently asked questions
Can I build a fintech app with an app builder?
Yes, for many fintech use cases. Personal finance trackers, budgeting apps, and expense managers are well-suited. Apps handling actual money transfers or banking require additional compliance infrastructure.
How do fintech app builders handle security?
Builders provide authentication and encryption. For financial data, add bank-grade security with services like Plaid for account linking, Stripe for payments, and dedicated encryption for sensitive data at rest.
What APIs do fintech apps typically need?
Common integrations include Plaid (bank account linking), Stripe (payments), Alpaca (trading), CoinGecko (crypto data), and Open Banking APIs for account aggregation.
Do fintech apps need special regulatory compliance?
Yes. Depending on the service, you may need PCI DSS compliance for payments, money transmitter licenses for transfers, or SEC registration for investment features. Consult a fintech compliance attorney.
