How to Avoid MEV
MEV (Maximal Extractable Value) refers to profit extracted from users by reordering transactions. Protect yourself from sandwich attacks and front-running.
Types of MEV Attacks
Sandwich Attack:Your swap gets sandwiched between attacker transactions, causing worse execution.
Front-running:Attacker sees your pending trade and executes first, profiting from price movement.

Step-by-Step Instructions
Understand MEV Risk
Large swaps and popular tokens are most targeted. Small trades on L2s are safer.
Tips
- ✓L2s have less MEV due to sequencer design
Add Flashbots Protect RPC
Add Flashbots RPC to MetaMask: rpc.flashbots.net
Tips
- ✓Transactions skip public mempool
Set Appropriate Slippage
Use tight slippage (0.5-1%) when possible. High slippage invites attacks.
Warnings
- ⚠Very low slippage may cause failed transactions
Use MEV-Protected DEXs
CoW Swap and other DEXs have built-in MEV protection.
Tips
- ✓CoW Swap batches trades to prevent MEV
Split Large Trades
Break large swaps into smaller pieces executed over time.
Tips
- ✓Reduces target size for attackers
Consider L2 Networks
Trade on Arbitrum, Base, or Optimism where MEV is less prevalent.
Tips
- ✓Sequencer design reduces MEV opportunities
