Onboarding friction with new crypto payment rails

We're exploring integrating some of the newer crypto payment rails for our international customer base, specifically looking at a few providers that offer stablecoin settlement for payouts. The promise of reduced cross-border fees and faster settlement is appealing, but the onboarding process, particularly the KYB requirements, feels surprisingly antiquated with some of them. It's almost as if they're still trying to fit traditional banking compliance into a decentralized model, which creates a lot of back-and-forth and extends the integration timeline significantly. Has anyone else experienced this, or found providers who have streamlined this effectively without compromising regulatory needs? It feels like there's a big gap between the tech's potential and the current operational reality for many.
