🥪 MEV SANDWICH: The Unwanted Snack on Every Trade
What is it? A bot spots your pending swap, buys before you (front-run), then sells after you (back-run), pocketing the price difference. You get worse fill price, bot gets free lunch.
─── 📊 HOW IT WORKS ───
• You place a market buy ETH at $2,000.
• Bot sees tx in mempool, buys ETH at $1,999.
• Your order pushes price to $2,002. Bot sells at $2,001. You got sandwiched.
─── ⚠️ RETAIL TRAP ───
• Trading without slippage tolerance = bot paradise. Set max slippage to 0.5% or use flashbots/private mempool.
• On bull runs (like now BTC +1.79%), sandwich attacks spike due to high volume. Stay sharp.
💡 TAKEAWAY: Public mempool is a battlefield. Use private transactions or limit orders to avoid being the bread in someone's sandwich.
