Laravel for Fintech

Laravel covers major attack vectors out of the box: CSRF, XSS, SQL injection, rate limiting. For fintech, we add layers: data encryption at rest and in transit, audit logs for all operations, two-factor authentication, API IP whitelisting, and privilege separation at the database level.

All monetary operations use minor units (cents) via integer arithmetic — no floats. We use the brick/money package for multi-currency calculations. All transactions are atomic via database transactions, with idempotency mechanisms to prevent duplication.

Yes. Our projects have passed PCI DSS Level 2 and SOC 2 audits. The architecture is designed from the start with regulatory requirements in mind: operation logging, access control, personal data encryption, data retention capabilities, and right to deletion.

We use pessimistic locking via Laravel Eloquent (lockForUpdate) for critical operations: account debits, wallet-to-wallet transfers. All financial operations are wrapped in database transactions with idempotent keys — a repeated request does not create a duplicate. For high-load scenarios, we use queues with unique job IDs and deduplication.

Laravel saves 3-4 months of development thanks to its ecosystem: Fortify + Sanctum for 2FA and API auth, Cashier for recurring payments, Horizon for queue monitoring, Telescope for debugging. For fintech, we add brick/money for precise calculations and spatie/laravel-activitylog for audit logging. This allows launching an MVP in 8-12 weeks instead of 6-8 months.

All amounts are stored in minor units (cents) as integers — no floats. The brick/money package provides precise multi-currency operations supporting 150+ currencies. Exchange rates are updated via API (ECB, central banks) on schedule or in real time. Conversion happens at transaction time with the rate recorded in the audit log.
