Can Layer 2 Scaling Solutions Inherently Reduce the Opportunity for MEV Front-Running?

Yes, Layer 2 (L2) solutions, particularly rollups, can reduce MEV front-running opportunities. L2s often use a sequencer to batch and order transactions before submitting them to Layer 1.

If the sequencer implements a fair ordering policy (e.g. strict first-in, first-out) and keeps the pending transaction pool private, it can mitigate front-running. The lower transaction costs and higher throughput on L2s also reduce the profit margin for gas-fee-based front-running.
