DEX aggregators acquire liquidity from multiple DEXs, enabling users to obtain more favorable token swap rates compared to any individual DEX. These aggregators possess the capability to optimize various factors such as slippage, swap fees, and token prices, resulting in superior rates for users when executed effectively.

For example, by distributing a swap transaction across several DEXs, investors can attain an overall improved swap rate compared to a swap performed solely on a single exchange.

The primary objective of a DEX aggregator is to provide users with superior swap rates compared to any specific DEX, all while minimizing the time required for the transaction. Additionally, they implement measures to safeguard users from price fluctuations and minimize the likelihood of failed transactions.

Another advantage to our DEX will be the ability to set limit orders on both buys and sells. We will also have promotional ads/spots for projects that will generate more revenue to the ecosystem. If you're a holder of Poleis you will be charged 0% per swap and if you're not yet a holder of Poleis a 1% fee will incur on each transaction you make through out the DEX. As with the other protocols these will be converted/sent out in ETH to our holders.
