# Don't Let Your Trading Become the Recipe of Someone's Sandwich

In a sandwich attack, the searchers/attackers 'sandwich' the victim's transactions between their own two transactions, called the front-run and the back-run. The victimized users suffer an implicit loss when these attackers reorder the transactions to benefit themselves.

You can visit the [Sandwich MEV introduction](https://eigenphi-1.gitbook.io/classroom/mev-types/sandwich-mev) in [EigenPhi's Classroom](https://eigenphi-1.gitbook.io/classroom/) to understand more about the basic idea behind it.

Next, we will walk you through some sandwich cases to show you how dangerous Sandwich MEV can be in terms of strategies under attack.
