Onboarding Friction with PSPs for High-Volume FX/Crypto Arbitrage

Hey everyone,

I've been running a small-scale arbitrage operation, primarily leveraging discrepancies between FX and crypto pairs on various exchanges. We're talking reasonably high transaction volumes, but individual ticket sizes aren't massive. The biggest bottleneck we're hitting consistently isn't the arb opportunities themselves, but the onboarding process with Payment Service Providers (PSPs).

Specifically, the KYB (Know Your Business) part feels like an endless loop of documentation requests, often for the same docs submitted weeks prior, or for information that isn't really relevant to our operational model. Some PSPs seem to have a 'one size fits all' approach to compliance that just grinds things to a halt, especially when dealing with the crypto side, even if it's fiat-to-crypto on-ramps/off-ramps for funding/de-funding. We've had a few instances where we were deep into the integration phase, only to be rejected at the very last minute for reasons that were never clearly articulated.

Are others experiencing similar hurdles, especially when trying to connect with PSPs that can handle both traditional finance and crypto-related flows? What strategies have you found effective in streamlining the KYB process, or identifying PSPs that are genuinely equipped to understand and onboard businesses with a hybrid asset focus without months of back-and-forth? Any tips on what to look for beyond just the advertised fees and payout speeds would be greatly appreciated.
