As the number of available DEXs multiplied exponentially , a new market for DEX aggregation came to life. Traders are able to define the trading pair and trade size and the aggregator identifies the most cost-efficient DEX to execute the trade. In some cases, the most efficient routing splits the trade across multiple venues. Aggregators increase the overall efficiency of the market by minimizing price impact and slippage.
As of writing DEX aggregators capture 25-35% market share of total volume traded on decentralized platforms. With the composable nature of DeFi, we are beginning to see more and more protocols integrate DEX APIs as part of applications with wider functionality such as wallets.
