12/12.🏗️ The Bottom Line:.MEV is here to stay, but we can fight back!. Builders: Implement protection layers.Users: Use private RPCs and tight slippage.Together we make the "Dark Forest" safer 🌲.The future is intent-based, private, and MEV-resistant! ⚡.

11/12.⚖️ Strategy Trade-offs:.Slippage/Deadline: Easy but limited protection.Commit-Reveal: Strong privacy but 2 txns.Batch Auctions: Excellent but complex.Private Orderflow: Great UX, external dependency.Intents: Future of trading.

10/12.💡 User Protection Tips:.🔐 Use wallets with private RPCs (Flashbots Protect).📉 Set tight slippage tolerances.⏰ Always use deadlines.🚫 Avoid trading illiquid pairs.📚 Stay informed on new protections.

9/12.📋 DEX Builder Checklist:.✅ Slippage controls enforced.✅ Deadline parameters required.✅ Displacement protection.✅ Consider commit-reveal for sensitive actions.✅ Reentrancy protection.✅ Educate users about private RPCs.✅ Security audit.

8/12.🎯 Strategy 5: Intent-Based Architecture. Revolutionary approach:.- Don't broadcast transactions.- Sign "intents" (what you want to achieve).- Solvers compete to execute optimally.- Nothing to front-run in mempool.

7/12.🔒 Strategy 4: Private Orderflow (Game Changer!). Skip the public mempool entirely:.- Use Flashbots Protect or MEV Blocker.- Transactions go to private relays.- Failed txns don't cost gas.- You might even earn MEV rebates! 💰.

6/12.⚖️ Strategy 3: Batch Auctions.Collect trades over time, settle all at uniform price. No advantage to being first = no front-running!. CoW Protocol pioneered this. Complex but powerful protection. Changes the trading model fundamentally.

5/12.🤫 Strategy 2: Commit-Reveal Schemes.Hide your intent from bots:.- Commit: Submit hash of your trade.- Reveal: Execute the actual trade later. Bots can't front-run what they can't see!.Tradeoff: 2 transactions = more friction.

4/12.🛡️ Strategy 1: Slippage & Deadline Protection.The basics every DEX MUST implement the code piece in the image below!. Non-negotiable first line of defense!

3/12.🥪 Sandwich Attack Breakdown:.- Bot sees your swap with 1% slippage.- Bot buys before you (price goes up).- Your trade executes at max slippage.- Bot sells after you (locks in profit).

2/12.⚡ What is MEV?.Maximal Extractable Value = the "invisible tax" on DeFi users. Bots scan the mempool, then reorder/insert/censor transactions to extract profit from:.- Front-running your trades.- Sandwich attacks.- Displacement attacks.

🧵🤖 MEV bots are taxing your DeFi trades behind the scenes. Every time you swap on a DEX, sophisticated bots can front-run, sandwich, or displace your transaction for profit. Here's how to fight back as both a builder and user 👇

Sunday Fun Fact:.The Checks-Effects-Interactions pattern is like updating your bank balance BEFORE handing someone cash. Otherwise they might grab the money and run before you realize you're broke!. Read more below👇
