Sandwich Attack
An MEV attack where a bot detects a large pending DEX swap, places a buy order immediately before it (frontrun — pushing the price up), lets the victim's trade execute at the worse price, then immediately sells (backrun — pocketing the price impact). The victim receives fewer tokens than expected; the bot profits from the spread. Protection: use MEV-resistant RPCs (Flashbots Protect), tight slippage tolerance, or intent-based protocols like CoW Protocol.
