sandwiching

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 the deterministic price slippage caused by available liquidity in the pool, which is deterministic . slipage is the change in the price of an asset during a trade.

• a softer side of sandwich attacks is on the lens of economic efficiency, on which an order can create a consumer surplus and the absence of a nash equilibrium. the bot operator would love the economic system back.
