0 / 5 completedWhat is MEV Extraction?
**Maximal Extractable Value (MEV)** is the profit searchers can extract by manipulating transaction ordering in a block. Originally called "Miner Extractable Value," it now includes validators and any party that can influence transaction inclusion and ordering. MEV is extracted through arbitrage, liquidations, sandwich attacks, and other sophisticated strategies.
Since Ethereum's merge, over **$1.4 billion in MEV** has been extracted. While often viewed negatively due to front-running, MEV also performs critical functions like keeping DeFi protocols healthy through liquidations and maintaining price efficiency through arbitrage. Understanding MEV is essential for both protecting against it and participating in the ecosystem.

MEV by the Numbers
Why MEV Matters
✅ Positive MEV
Liquidations keep lending protocols solvent. Arbitrage maintains price efficiency across DEXes. JIT liquidity improves trade execution.
❌ Negative MEV
Sandwich attacks extract value from users. Front-running causes slippage. Priority gas auctions (PGA) drive up network costs for everyone.
⚖️ Neutral MEV
Back-running trades to capture arbitrage doesn't harm users. Statistical arbitrage exploits predictable patterns without front-running.
