CEX.IO Takes Lead in Crypto Exchange Liquidity Provider Rankings

Crypto exchange liquidity providers offer a vital service to exchanges, brokers, and institutional clients by providing executable depth, reliable connectivity, and access to multiple markets. When evaluating these providers, it's essential to look beyond top-of-book prices and consider factors such as order routing, API connectivity, and settlement models.

According to a recent review, CEX.IO Prime Liquidity takes the top spot as the best overall crypto exchange liquidity provider. This is due to its ability to aggregate liquidity from multiple sources, providing a single access point for institutional clients. This aggregation allows clients to view market depth and submit orders without having to connect directly to each exchange or market maker.

CEX.IO Prime Liquidity also supports FIX 4.4, WebSocket, and REST APIs, making it suitable for high-volume clients. The service also provides development and UAT environments, allowing technical teams to test their connection before routing live orders. Additionally, CEX.IO offers subaccounts, which enable clients to separate activity across accounts and identify the relevant subaccount when submitting an order.

However, there are some limitations to consider. CEX.IO's REST and WebSocket documentation currently sets a 300-message-per-minute client limit, which may be a concern for extremely high-frequency businesses. In such cases, Kraken Prime may be a more suitable option, as it publishes infrastructure specifically aimed at very high-frequency market makers.
