Onboarding friction with new liquidity providers

We've been vetting a few new LPs to diversify execution and mitigate single-provider risk, particularly on some less liquid crosses where we've seen slippage widen recently. The KYB process has been surprisingly inconsistent across the board. Some are incredibly streamlined, almost entirely digital, while others still require a stack of notarized documents and weeks of back-and-forth. It's creating a bottleneck internally, and I'm curious if others are experiencing similar inefficiencies when trying to integrate new partners, or if we're just hitting a few laggards.
