MEVengers

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.

MEVengers is built as a complete end-to-end ecosystem integrating cutting-edge Web3 infrastructure with accessible Web2 UX.

Technical Innovations

🎯 Time-Weighted Auction Mechanics

We implemented a novel auction system where earlier bidders receive time-based bonuses, creating incentives for rapid community response to MEV threats while maintaining fair price discovery.

🚨 Emergency Circuit Breaker Pattern

Built a comprehensive pause mechanism that can halt all operations except admin functions during security incidents, with granular permission controls that allow owners to operate even during emergency states.

💰 MEV Insurance Integration

Created a community-funded insurance system where auction proceeds automatically contribute to a victim compensation fund, turning MEV protection into a positive-sum community endeavor.
