# AI path finder Swap

When trading using a single DEX, there may be cases where the lowest price is not available for the same token. Even between large exchanges such as Uniswap, SushiSwap, Balancer, and Curve, price differences occur in real time, and in the case of highly volatile cryptocurrencies such as Meme Coin, AMM is subject to more severe price changes depending on liquidity changes that occur more price impact.

For this reason, you will not be able to find the optimal price when using a single exchange, and you will also experience losses on transactions above a certain amount.
