Analyzing Maximal Extractable Value (MEV) Extraction Across Ethereum and Layer-2 Rollups

Maximal Extractable Value (MEV) is widely prevalent across Ethereum and prominent Layer-2 rollups, with trading volume comparable to Ethereum. While MEV costs are lower on rollups, profits are also significantly lower compared to Ethereum. The authors also identify the potential for cross-layer sandwich attacks facilitated by transactions sent across rollups and Ethereum.
