Can I Use My Own Payment Processor? (2026 Fintech Rules)

The question in full

The question Can I use my own payment processor? is the most critical hurdle for fintechs moving from MVP to scale. In 2026, the answer is 'Yes, but with caveats.' While you can choose your own technical rails (like Stripe, Adyen, or a proprietary gateway), that processor must be capable of Speaking the Language of your Principal License Holder.

Answer

You can, but only if you are a payment facilitator and have an agent-based relationship with the US solution provider. The reason is, when you use your own payment processor you are in the custody of funds and hence break the chain of licensure continuity. Your own payment processor is a contract with your company and your processor. The US solution provider is not a party to that contract and neither do they have a primary chain of custody to client funds. Hence, the answer is no.
