Scaling Liquidity Solutions for Crypto Futures Platforms

We're currently scaling out our crypto futures platform and constantly evaluating our liquidity providers. The challenge isn't just about raw spread competitiveness, but more about the depth available at various price points, especially during volatile periods like major economic releases or unexpected market shifts. We've seen significant divergence in fill rates and slippage across different venues when volume spikes, leading to inconsistent client experiences. My question to others running similar operations is, how are you effectively managing and diversifying your liquidity relationships to mitigate these risks? Are you finding success with a multi-prime broker model, or are you seeing better outcomes from deeper, more integrated relationships with fewer, higher-tier providers? We're particularly interested in the operational overheads associated with managing multiple direct API connections versus aggregated solutions.
