Ethereum MEV: Transaction Ordering, DeFi Strategies, and Mitigation
Summary
This report explains maximal extractable value (MEV) as profit available to block producers through transaction ordering, and describes why decentralized finance creates opportunities for it. The main strategy categories identified are arbitrage across decentralized exchanges, liquidations, and sandwich trades. It connects MEV to Ethereum’s account-based transaction model, where sequential execution and smart contracts can make coordinated transaction bundles easier to construct than in a UTXO system.
The report argues that MEV is tied to incentives that help permissionless networks prioritize transactions and resist spam, so eliminating it entirely may be unrealistic. It can correct price differences and support market efficiency, but can also expose users to slippage, destabilize consensus, and concentrate block production when some operators have an advantage. Flashbots Auction is presented as infrastructure that made opportunities easier to access, alongside discussion of protocol, application-design, and educational responses. Historical earnings figures are cited, but the report notes that measurements depend on tracked protocols and activity; the supplied excerpt also ends before the full treatment of proposed solutions.
Key ideas
- MEV is value captured by block producers through their ability to order transactions within a block.
- Arbitrage, liquidations, and sandwich trades are major MEV strategies in Ethereum DeFi.
- Ethereum’s account model and sequential execution can simplify the construction of transaction bundles.
- MEV can improve price consistency while also causing user harm, consensus pressure, and economic concentration.
- Mitigation involves protocol design, decentralized application design, and greater awareness of on-chain strategies.
