## MEV in Rollups

MEV, or Maximal Extractable Value, in rollups refers to the profit that sequencers or other actors can extract by manipulating the order of transactions within a batch. Because sequencers have control over the transaction sequence, they can perform actions like front-running, back-running, or sandwiching to capture arbitrage opportunities or liquidate positions.

This is a significant challenge for rollup designers, as it can lead to negative user experiences and unfair market outcomes. While MEV is an inherent part of decentralized finance, its impact in rollups can be more concentrated due to the role of the sequencer.

Solutions like fair sequencing services, encrypted mempools, and threshold decryption are being explored to mitigate the adverse effects of MEV. Understanding MEV is crucial for designing fair and efficient trading environments that protect users from exploitation.

It is a central theme in the study of market microstructure within the crypto domain.
