Finwy is a reference implementation for teams who want Stripe/Razorpay-grade UX with clear boundaries: Prisma models for users, wallets, and transactions; ledger rows for every movement; JWT access tokens with rotating refresh sessions; and an admin surface for operations.
This stack is intentionally opinionated—security headers, CSRF on state-changing APIs, Zod at the edge of your domain, and audit logs for sensitive actions—so you can extend it without rewriting foundations.
