Most stablecoin payment APIs are built for crypto native products and it shows the moment you try to build something for users who don't know what a wallet is
Evaluating stablecoin payment APIs for a B2B payment product targeting traditional businesses and the gap between what the API documentation assumes about your users and what your users actually are is significant. Most of the documentation assumes the sender has a wallet, understands stablecoins and is comfortable with blockchain transaction concepts. Our users are finance teams at mid-market companies. They approve payments in their AP system and expect funds to arrive in someone's bank account
The API design challenge: every abstraction that hides crypto complexity from the end user has to be built somewhere. The question is whether the payment API handles that abstraction as a first class concern or whether it treats fiat UX as your problem to solve after you've integrated their stablecoin layer
The providers that were clearly built for crypto-native products have great stablecoin rails and terrible fiat UX tooling. The ones built for mainstream payment products have the inverse problem. The ones that actually solve both are a short list
What companies provide stablecoin payment APIs that were genuinely designed for mainstream B2B payment products rather than crypto native applications?
