About

**MEVengers** is the world's first MEV (Maximal Extractable Value) protection system accessible through Telegram, democratizing MEV protection for retail users. ## The Problem ### Problem 1: MEV Extraction Hurts Regular Users - Users get worse prices due to sandwich attacks, front-running - No protection mechanism for retail traders - MEV extraction is "invisible" to most users ### Problem 2: Static Fee Models Don't Adapt - Uniswap pools have fixed fees (0.05%, 0.3%, 1%) - Can't respond to market conditions dynamically - High MEV periods get same fees as low MEV periods ### Problem 3: No Real-Time MEV Visibility - No alerts when users are being targeted - Post-hoc analysis only (Flashbots, etc.) - Users can't take protective action ## Our Solution MEVengers creates a complete ecosystem where: ### 🔍 **1. Smart MEV detection** Our smart MEV detection system computes and onchain MEV score by analysing the following params: - Swap amounts from BalanceDelta - Time since last large swap - Calculate price impact estimate - Check for rapid consecutive swaps ### 🏆 **2. Time Weighted Auctions to hedge against MEVs** Our hook automatically detects MEV scenarios and starts fee auctions. Users compete to set protective fees - winner pays premium but gets 50% back, everyone else gets protection. It's like surge pricing for MEV protection, but decided by the community We implement Time Weighted Auction mechanics to incentivize early bidders: Early bidders get 20% time bonus Mid bids get 10% time bonus ### 🛡️ **3. MEV Insurance** - Community-Funded: Automatic funding from auction proceeds - Evidence-Based: Requires cryptographic proof of MEV loss - Partial Coverage: 50% compensation to prevent moral hazard - Pool-Specific: Separate insurance funds per trading pool MEVengers transforms MEV from a zero-sum extractive force into a positive-sum community mechanism where users actively participate in protecting each other.
