## sandwiching

<br>

### tl, dr

* sandwiching occurs when a searcher identifies a profitable trade in the mempool that will cause an impact on the price of an asset.

* a searcher buys or sells a calculated amount directly before the large trade is executed and then immediately exits their position after the large order has taken place, banking a profit.

* the main theme of sandwich attacks is slippage caused by available liquidity in the pool.
