# MEV extracting

Every time users do swaps on a DEX, they change the prices in certain AMM pools, which creates arbitrage opportunities that usually benefit a small group of people: MEV bots.

Split changes the rules of the game and grasp these opportunities directly in the user's transaction; up to 60% of the profit from the opportunity created by a trader is returned as cashback.&#x20;

**What's the magic?**\
1\. Protocol uses AAVE Flashloan and doesn't need its liquidity for MEV extracting;

2\. Algorithm efficiency is 87%+;

3\. Trader recovers up to 60% of the slippage;

4\. User doesn't even have to pay gas fees.

{% hint style="info" %}
**The protocol extracts MEV from users' transactions using other pools without impacting them.**
