Onboarding Friction for High-Volume FX/Crypto Operators – Anyone Cracking the Code?

We've been scaling up our platform, seeing decent volume particularly in $EURUSD and some of the major crypto pairs. The recurring headache, though, is the onboarding process with new liquidity providers and payment service providers. It feels like every time we try to integrate, we're reliving the same exhaustive KYB process, even with entities we've already done business with in other capacities.

It's not just the time sink; it's the sheer inconsistency in documentation requirements and the lack of clarity on what triggers certain review tiers. This inevitably delays go-live dates and ties up significant operational resources. Is anyone finding more streamlined approaches, perhaps specific tech stacks or partnerships that mitigate this perpetual friction? We're talking beyond the basic API integration; more about the regulatory and compliance hurdles. Looking for practical experience here, not just hypothetical solutions.
