MEV (最大抽出可能価値): what is it?
バリデータやボットがブロック内のトランザクション順序を操作（サンドイッチ攻撃等）することで抽出する最大利益。
🎯 Key Takeaways & Use Cases
✓MEV = value from reordering, including, or excluding transactions in blocks beyond regular fees.
✓Solana’s lack of a public mempool and fast transaction propagation changes how MEV works vs chains like Ethereum.
✓Tools like Jito bundle auctions are central in current Solana MEV infrastructure.
✓Some forms of MEV can harm regular users (especially in low liquidity or high slippage scenarios).
✓Monitoring MEV and using transaction protection or choosing infrastructure wisely can help reduce negative impacts.
💡 Real-World Examples
A searcher sees a large trade about to happen on a Solana DEX, and arranges a bundle that front-runs that trade to profit from the price move.
During a token launch with high slippage tolerance, bots may try sandwich attacks (placing one transaction right before and one right after a user’s trade) to extract value from the user’s worse execution.
Validators using Jito client receiving tips from bundles and prioritizing or accepting transactions that offer higher “priority fees” or user incentives, even absent a public mempool.
⚡ Pro Trading Tips
▸Pay attention to which validators use MEV-aware clients (like Jito) since that influences how transaction bundles and tips are handled.
▸If trading on Solana, be aware that high slippage and low liquidity make trades more vulnerable to sandwich attacks.
▸Use tools or dashboards to monitor MEV activity (e.g. sandwich attack detectors, MEV dashboards) so you can see when MEV is likely impacting trades.
