Check if a Pool Exists
Check if the liquidity pool for a pair of HTS tokens exists on-chain.
When adding a new or existing liquidity pool, the initial step is typically to verify if the liquidity pool already exists before determining the next course of action. The factory contract provides a method to retrieve the pool address, if it exists, as shown below.
Checking if the liquidity pool exists using SaucerSwap's REST API is also a suitable alternative. For more information, see Get V1 liquidity pools
