Beyond Stripe: Modular Payment Architectures for Global SaaS
Prototype a payment abstraction layer that routes to at least two providers and implements webhook handling.
Start building a payment API abstraction that supports Stripe and a stablecoin provider with webhook endpoints.
Summary
The author explains the limitations of traditional processors like Stripe and PayPal, such as strict compliance rules, account restrictions, and limited global flexibility. He explores emerging architectures that use multiple payment providers, API‑first layers, and hybrid fiat/stablecoin settlement models. Prototypes include payment API abstraction layers, webhook‑based transaction handling, stablecoin settlement flows, and simple payment link generators. Key takeaways emphasize that flexibility comes from combining systems, that API design matters more than the payment method, and that risk management is a core part of the system. The author invites feedback and shares a link to his prototype repository for further exploration.
