MEV (Miner Extractable Value) has a significant impact on DeFi users. Learn how to protect yourself from MEV attacks.

What is MEV?​

MEV refers to the extra profit miners or validators can extract by reordering, inserting, or censoring transactions.

Common MEV Attacks​

1. Front-running​

An attacker sees your transaction and executes a similar one with a higher gas fee to get priority.

2. Sandwich Attacks​

Inserting trades before and after your transaction to manipulate the price for profit.

Protection Measures​

Using MEV Protection Tools​

  • Flashbots Protect: Private transaction pool.
  • CowSwap: MEV-protected DEX.
  • 1inch Fusion: MEV-resistant trades.

Trading Strategies​

  1. Set reasonable slippage tolerance.
  2. Execute large trades in smaller batches.
  3. Use limit orders instead of market orders.

Technical Principles​

Flashbots​

Avoids public monitoring of transactions through a private mempool.

Order Flow Auctions​

Allows users to benefit from MEV rather than be exploited by it.

Future Developments​

  • PBS (Proposer-Builder Separation).
  • Encrypted mempools.
  • Fair ordering protocols.

Conclusion​

Understanding MEV and taking protective measures can help reduce trading losses.
