Do L2 Solutions Completely Eliminate MEV Opportunities for Their Own Sequencers?

No, Layer-2 solutions do not completely eliminate Maximal Extractable Value (MEV); they shift the opportunity from the Layer-1 validator to the Layer-2 sequencer. The sequencer is the entity responsible for ordering and batching L2 transactions.

This entity gains control over transaction ordering within the L2 environment, creating new MEV opportunities like front-running and arbitrage that are local to the L2. Solutions are being developed to decentralize the sequencer role to mitigate this.
