# Dex Aggregator

What is a DEX aggregator?

The purpose of a DEX aggregator is to help users find the best rates for token swaps without needing to compare prices on different Decentralized Exchanges. Instead of relying on a single DEX, the aggregator aims to achieve 3 objects:

1. Finding the Best Price
2. Finding the Lowest Slippage
3. Reducing protocol and gas fees
