MEV (Maximal Extractable Value)
The maximum profit that can be extracted by a block validator or builder by reordering, inserting, or censoring transactions in a block, beyond standard block rewards and gas fees. Common MEV strategies include sandwich attacks (profiting from large DEX trades), DEX arbitrage (exploiting price discrepancies between pools), and liquidation MEV (racing to liquidate undercollateralised positions). MEV extraction is estimated to have exceeded $2 billion on Ethereum by 2025.
