Best Price Routing (BPR) plays a crucial role in the CrowdSwap program. Its programming code is designed to automatically identify and execute transactions with the most favorable prices across various liquidity pools or exchanges. Liquidity pools represent aggregated funds facilitating trading on decentralized exchanges, and varying prices for the same asset may arise due to supply and demand fluctuations in different pools. Best price routing aims to optimize trades by accessing liquidity from multiple pools, thereby securing the best overall execution price for a given trade. The capabilities of BPR are contingent upon integrating decentralized exchanges across diverse blockchains.
