Fintech App challenges we solve
Common fintech app issues in apps built with Tempo Labs or v0.
Data encryption and storage
Financial data must be encrypted at rest and in transit. Account numbers, transaction histories, and personally identifiable financial information need field-level encryption, not just HTTPS. AI tools store financial data in plain text in the database, which is a compliance violation waiting to happen.
Transaction integrity
Financial transactions must be atomic — money debited from one account must be credited to another, with no in-between state where it disappears. AI-generated code doesn't use database transactions, meaning a server crash mid-operation can leave accounts in an inconsistent state.
Audit trail and compliance
Every financial action needs an immutable log — who initiated it, when, what changed, and what the balances were before and after. Regulators require this. AI tools don't generate audit logging, and retrofitting it into an existing codebase is tedious but essential.
Third-party financial API integration
Connecting to Plaid, Stripe, or banking APIs requires handling OAuth flows, webhook verification, idempotency keys, and retry logic for failed calls. AI tools generate the initial API call but miss the error handling and reliability patterns these services require.
Authentication and fraud prevention
Financial apps need multi-factor authentication, session timeout policies, device fingerprinting, and suspicious activity detection. Basic email/password auth from AI tools is nowhere near sufficient for an app that touches people's money.
Number precision and currency handling
JavaScript floating-point math causes rounding errors with money — $0.1 + $0.2 !== $0.3. AI tools use standard floats for currency calculations, which leads to penny discrepancies that compound over time and break reconciliation.
