What is MEV and how does it affect me?
Short answer
MEV (maximal extractable value) is profit that specialized bots extract by reordering, inserting, or censoring transactions in a block — for example via sandwich attacks or arbitrage. On Solana it often flows through validator ordering and tip auctions.
As a retail trader, you mostly experience MEV as worse-than-expected fills and the occasional failed swap. You cannot eliminate it, but you can reduce your exposure.

How does MEV hurt my trades?
Most directly through sandwiching — a bot bracketing your swap so you fill worse. You can also be back-run on arbitrage your trade creates.
How do I reduce MEV exposure?
Keep slippage tight on deeper pools, reduce size on thin ones, and use private transaction routing where available.
Can I avoid MEV completely?
No — it is structural wherever transaction ordering has value. You can only minimize your exposure, not remove it.
