MEV (Maximal Extractable Value)
Value that block producers or sophisticated searchers can extract by reordering, inserting, or censoring transactions.

MEV is value extracted from users via transaction ordering — sandwich attacks, frontrunning, and back-running. MEV-protected order flow (CoW Swap, MEV Blocker, Flashbots Protect) routes transactions through private mempools or batch auctions to neutralize the attack surface.
