🔗 EigenLVR: A Uniswap v4 Hook to Mitigate Loss Versus Rebalancing (LVR) via EigenLayer-Powered Auctions
EigenLVR is a revolutionary Uniswap v4 Hook designed to address Loss Versus Rebalancing (LVR) — a critical issue facing liquidity providers (LPs) — by redirecting value lost to arbitrage back to LPs via a sealed-bid auction mechanism secured by EigenLayer.
Traditional AMM designs expose LPs to impermanent loss due to the delay between off-chain price updates and on-chain trading. In this temporal window, arbitrageurs exploit price discrepancies to their advantage, capturing MEV that rightfully belongs to LPs. EigenLVR introduces a block-level priority auction — executed and validated off-chain via an EigenLayer-secured AVS (Actively Validated Service) — that auctions off the first trade of each block and redistributes MEV revenue directly to LPs.
🏆 Built for Uniswap v4 Hook Hackathon - Advanced Hook Design / AVS Integration Category
Loss Versus Rebalancing (LVR) is the profit that arbitrageurs extract from AMM liquidity providers due to stale prices. It occurs because:
- Price Discovery Lag: Off-chain markets (Binance, Coinbase) update continuously, but AMMs only update when trades occur
- Block Time Delays: ~13-second block times on Ethereum create profitable arbitrage windows
- MEV Extraction: Arbitrageurs rebalance pools to match external prices, capturing profits meant for LPs
- Value Leakage: Current MEV goes to searchers, block builders, or validators — not the LPs providing liquidity
📊 Example: ETH/USDC Pool ($10M TVL)
┌─────────────────────────────────────────────────────────────┐
│ Off-chain Price: $3,000 → $3,050 (1.67% increase) │
│ On-chain Pool Price: Still $3,000 (awaiting arbitrage) │
│ Arbitrage Opportunity: $167,000 profit available │
│ LP Loss: ~$83,500 (0.83% of TVL) captured by arbitrageur │
│ Annual LVR Impact: $1.2M+ lost from this pool alone │
└─────────────────────────────────────────────────────────────┘
EigenLVR fundamentally changes MEV distribution through sealed-bid auctions:
- 🔍 LVR Detection: Price oracles detect profitable arbitrage opportunities
- ⚡ Auction Trigger: Hook automatically initiates sealed-bid auction for first block trade
- 🏆 Winner Selection: EigenLayer AVS operators validate bids and select winner
- 💰 Revenue Redistribution: 85% of auction proceeds flow directly to LPs
- 🔒 Cryptographic Security: BLS signatures ensure auction integrity
- For LPs: Recover 85% of lost MEV as direct rewards
- For Arbitrageurs: Fair, transparent bidding process
- For AVS Operators: 10% commission for validation services
- For Protocol: 3% fee for development and maintenance
