PSP (Payment Service Provider)

Payment service providers handle the movement of funds between payers and payees — from card processing to bank transfers. PSD2 (EU) and state money transmitter licensing (US) define the regulatory categories. Stripe, Adyen, Checkout.com, and Nuvei are integrating stablecoin settlement rails alongside traditional card networks. Modern Treasury launched PSP infrastructure for stablecoin-native payment operations in February 2026.
