Application Layer MEV

Definition

Application Layer MEV involves extracting value from transactions at the level of decentralized applications. This form of value extraction occurs through specific smart contract interactions rather than solely at the blockchain’s base layer. It refers to the profit opportunities available to participants who can influence the ordering or inclusion of transactions within a block by interacting directly with application logic. Such opportunities arise from actions like liquidations, arbitrage, or sandwich attacks performed against user trades on decentralized exchanges.
