Q4. Why are dex aggregators like 1inch useful?
Ans: For any exchange market, whether it's equities, commodities, currencies, or cryptocurrencies, prices and transaction fees vary significantly. The decentralised nature of cryptocurrencies allows for exchange markets to be decentralised as well.  This means that by using decentralised exchanges that cut out middlemen and subsequently decentralised exchange aggregators, traders and investors can access even lower prices. Instead of manually checking each and every exchange or decentralised exchange, dex aggregators allow traders to directly access the best possible price across exchanges.
