LVR Auction Hook 🔐

🏆 Winner Announcement

🎉 First Place Winner - EigenLayer Track at UHI6 Hookathon!

We're thrilled to announce that LVR Auction Hook won first place in the EigenLayer Benefactor Track at the Uniswap v4 Hookathon (UHI6)!

Official Announcement by Atrium Academy

This recognition validates our approach to redistributing MEV profits to liquidity providers through EigenLayer's Actively Validated Services and Uniswap v4's programmable hook system.

A MEV redistribution infrastructure that combines Uniswap v4 Hooks with EigenLayer's Actively Validated Services (AVS) to auction first-in-block trading rights and redistribute arbitrage profits directly to liquidity providers. LVR Auction Hook turns Loss Versus Rebalancing into LP revenue streams.

Uniswap v4 Hookathon (UHI6) Submission - EigenLayer Benefactor Track

A MEV redistribution infrastructure that combines Uniswap v4 Hooks with EigenLayer's Actively Validated Services (AVS) to auction first-in-block trading rights and redistribute arbitrage profits directly to liquidity providers. LVR Auction Hook turns Loss Versus Rebalancing into LP revenue streams.

🤝 Partner Integration

EigenLayer Integration

This project is built using the official Hourglass DevKit template for EigenLayer AVS development, providing:

Distributed Consensus: Multiple operators validate price discrepancies and auction results
Cryptoeconomic Security: Slashing mechanisms prevent malicious behavior
Economic Incentives: Operators earn rewards for accurate price monitoring
Scalable Architecture: Built on EigenLayer's proven AVS infrastructure

Uniswap v4 Integration

Built on Uniswap v4's programmable hook system:

Hook Interface: Implements beforeSwap, afterSwap, and liquidity management hooks
Pool Integration: Seamlessly integrates with existing Uniswap v4 pools
MEV Capture: Captures arbitrage opportunities at the pool level
LP Protection: Directly benefits liquidity providers who suffer LVR losses

🎯 Problem Statement

Traditional AMMs suffer from severe value extraction that harms liquidity providers:

LVR Exploitation: Arbitrageurs extract $500M+ annually from stale AMM prices
MEV Concentration: Current PBS auctions benefit validators, not affected LPs
Price Lag Vulnerability: 13-second block times create profitable arbitrage windows
LP Value Leakage: LPs lose money to sophisticated traders while providing liquidity
No Compensation: LPs bear arbitrage costs but receive no auction proceeds

💡 Solution: EigenLayer-Secured MEV Auctions

Our solution redistributes MEV profits to liquidity providers through cryptoeconomically secured auctions. LVR Auction Hook captures arbitrage opportunities and auctions first-in-block trading rights, with proceeds flowing directly to LPs who suffered the price impact.

Key Innovation

MEV Redistribution: Auction proceeds compensate LPs for LVR losses
Cryptoeconomic Security: EigenLayer operators secure auction integrity through slashing
First-in-Block Auctions: Sealed-bid auctions for priority trading rights
LP Compensation: Direct distribution of auction proceeds proportional to liquidity provision

🏆 Core Component: LVR Auction Hook

The heart of this project is src/hooks/LVRAuctionHook.sol - a comprehensive Uniswap V4 hook that implements the complete LVR auction system:

🎯 What it does:

🔍 Price Monitoring: Continuously monitors price deviations using Chainlink oracles
⚡ Auction Triggering: Automatically triggers auctions when LVR thresholds are exceeded
💰 Bid Processing: Validates and processes auction bids from MEV searchers
🏅 Winner Selection: Determines auction winners and grants execution rights
💸 MEV Redistribution: Redistributes captured MEV profits directly to liquidity providers
📊 Settlement: Handles auction settlements and reward distribution

🛠️ Technical Implementation:

Implements Uniswap V4 hook interface (beforeSwap, afterSwap, etc.)
Integrates with EigenLayer AVS for distributed consensus
Uses Chainlink price feeds for accurate price monitoring
Employs auction libraries for bid validation and settlement logic

🔗 AVS Integration:

The hook interfaces with the Hourglass DevKit AVS (/avs-new/) which provides:

Distributed task coordination across multiple operators
Consensus mechanisms for auction results validation
EigenLayer integration for operator staking and slashing
