What are the advantages of rapid DeFi trading aggregators? How to capture value?

Decentralized trading aggregators, which were once not highly valued by venture capital institutions, are gradually becoming another decentralized finance (DeFi) application highly sought by the market, following DEXs, lending platforms, and oracles. The reason is quite understandable. With the increasing number of Ethereum DEXs, liquidity has been dispersed across various protocols or liquidity pools, leading to higher comprehensive trading costs for users. The emergence of aggregators not only significantly reduces trading costs but also improves user experience.
