Onboarding for high-volume crypto payments – friction points

Been exploring options for a new venture processing significant daily volumes of crypto payments, specifically for cross-border B2B transactions. We're talking substantial sums flowing in and out, needing rapid conversion to fiat ($USD, $EUR). The usual suspects among the major payment processors seem to have an archaic approach to crypto, viewing it more as an edge case than a core offering.

The onboarding friction has been palpable. KYB processes are often geared towards much lower-volume retail clients, or they treat crypto like a red flag from the outset, demanding documentation that's either excessive or simply not relevant to our operational structure. It’s almost as if their compliance departments haven't quite caught up to the realities of a legitimate, regulated business operating with digital assets. We’re seeking reliability and speed, especially on payouts and fiat conversion, but finding a partner that understands the nuances of higher-value crypto transfers without creating unnecessary bottlenecks at the initial stages has been a genuine challenge. Wondering if others have encountered similar issues, particularly with PSPs or regulated entities that claim to be crypto-friendly but then present significant hurdles in practice.
