Jupiter Aggregator is a Solana-based DEX aggregator that enables users to trade crypto across multiple DEXes by aggregating the majority of the liquidity sources available on  Solana into a single endpoint with the goal of best price point execution for users. By scanning and comparing the prices and liquidity of different DEXes, Jupiter Aggregator uncovers the best swap rate for traders and executes the trade such that it's optimized for slippage and fees.
