What Is ‘Miner Extractable Value’ (MEV) and How Does It Relate to Transaction Fees?

Miner Extractable Value (MEV) is the profit a miner (or validator in PoS) can earn by strategically including, excluding, or reordering transactions within the blocks they produce. This value is extracted above the standard block reward and transaction fees.

MEV is often generated by exploiting arbitrage opportunities in decentralized exchanges or by liquidating loans, and it represents an additional, often hidden, source of revenue.
