Introduction
Decentralized finance (DeFi) has transformed financial ecosystems through protocols like Uniswap, which employ automated market-making mechanisms. This article presents a specialized backtesting framework for concentrated liquidity market makers (CLMM) on Uniswap V3, leveraging parametric models to approximate liquidity distribution and quantify pool rewards.
Key Features of the Framework
Parametric Liquidity Modeling:
- Approximates liquidity distribution using statistical tools to mirror CLMM pool dynamics.
- Enables accurate reward estimation for liquidity providers (LPs).
Historical Data Integration:
- Validated against 2023 data from Uniswap V3 pools (altcoin pairs, stablecoins, and USDC/ETH across varying fee tiers).
- Achieved <1% modeling error in reward-level predictions.
Strategic Applications:
- Simulates trading strategies and liquidity provision scenarios.
- Quantifies potential LP returns and aids in risk assessment.
Methodology
Step 1: Liquidity Distribution Approximation
- Uses a parametric model to estimate liquidity concentration within price ranges.
- Example: For USDC/ETH pools, the model accounts for fee-tier volatility adjustments.
Step 2: Reward Estimation
- Integrates historical trade volume and price data.
Outputs:
- Expected LP rewards.
- Pool-specific ROI metrics.
Step 3: Error Validation
- Benchmarked against actual 2023 pool performance.
- Demonstrates reliability for future LP revenue projections.
Case Study: 2023 Pool Analysis
| Pool Type | Fee Tier | Modeling Error |
|-----------------|----------|----------------|
| Altcoin Pairs | 1% | 0.85% |
| Stablecoin Pairs| 0.05% | 0.72% |
| USDC/ETH | 0.3% | 0.91% |
