Sandwiching occurs by placing one order before the transaction and another immediately after, which ensures that retail always gets the worst possible price.
The Solana Foundation has removed a group of validator operators from its delegation program due to their involvement in sandwich attacks on traders.
In a Sandwich attack, a malicious trader searches the network of their choice, such as Ethereum, for a pending transaction. Sandwiching occurs by placing one order before the transaction and another immediately after.
The attacker will position the first pending transaction between a front-run and a back-run, both occurring simultaneously, to manipulate the asset's price and profit from the difference.
