The majority of liquidity pools are of two assets, and a majority of those include pairing a network's native token to any other token. See AVAX-SNOB on Avalanche for example, or AVAX-PNG, AVAX-JOE, etc. Why? Well, the native token of any given network is by definition needed by the network's users, and thus has great liquidity, volume and use cases. It is also generally extremely easy to wrap that token to use in liquidity pools.
