KYB for crypto payouts – finding a reliable rails partner

Running into some persistent issues with Know Your Business (KYB) checks for crypto payouts, specifically finding a partner that can handle high-volume, global transactions without significant friction. We're an established e-commerce platform and the usual suspects for payment processors are proving cumbersome, especially when it comes to certain jurisdictions and the speed of funds settlement. We're not talking about outright rejections, more like lengthy review times and inconsistent requirements.

Has anyone here navigated this successfully for crypto payouts at scale? Are there particular types of PSPs or solutions that have offered a smoother experience for the KYB portion while maintaining decent payout reliability and competitive fees?
