Key Takeaways

You've learned how MEV extraction works, from identifying opportunities to calculating profitability and understanding ecosystem impacts. Let's review the key concepts before testing your knowledge.

💰 MEV Fundamentals

MEV (Maximal Extractable Value) is profit extracted by manipulating transaction ordering. Since Ethereum's merge, over $1.4 billion has been extracted through various strategies.

  • Four main strategies: arbitrage (65%), liquidations (20%), sandwich (10%), JIT liquidity (5%)
  • Supply chain: Searchers → Builders → Relays → Validators
  • 90% of MEV now flows through Flashbots MEV-Boost

🎯 Extraction Strategies

Each strategy requires different technical skills, capital, and infrastructure:

  • Arbitrage: Exploit price gaps across DEXes ($50-$5k profit, very high frequency)
  • Liquidation: Repay underwater loans for 5-15% bonus ($100-$50k, high frequency)
  • Sandwich: Front-run and back-run large trades ($20-$2k, ethical concerns)
  • JIT Liquidity: Add liquidity just-in-time ($500-$100k, requires huge capital)

📊 Profit Calculation

Profitability requires careful accounting of all costs and risks:

  • Formula: Net Profit = Revenue - Gas Cost - Slippage - Competition
  • Gas optimization is critical—every 1000 gas = $0.06 saved at 30 gwei
  • Use Flashbots bundles—failed transactions don't cost gas
  • Success rate matters: 60-80% typical, calculate expected value

🌐 Ecosystem Impact

MEV has both positive and negative effects across the ecosystem:

  • Positive: Arbitrage maintains price efficiency, liquidations protect lenders, MEV-Boost increases validator APY by 60%
  • Negative: Sandwich attacks cause 5-10% slippage, network congestion, centralization pressure, information asymmetry
  • Solutions: Flashbots Protect (private mempool), MEV-Share (user rebates), CoW Protocol (batch auctions), threshold encryption

🔮 Future Outlook

MEV landscape continues evolving with new technologies and solutions:

  • Cross-chain MEV: Arbitrage across L2s and bridges becoming major opportunity
  • Protocol-level solutions: SUAVE, encrypted mempools, fair ordering coming to Ethereum
  • MEV redistribution: More protocols implementing MEV-Share style rebates to users
  • Regulation: Governments viewing toxic MEV as market manipulation, expect scrutiny
