Analyze Liquidity Pool

Comprehensive analysis of DeFi liquidity pools with impermanent loss calculations, APY projections, risk assessment, and optimization strategies across multiple DEX protocols and chains.

Overview

The liquidity pool analyzer provides institutional-grade analysis for liquidity providers across Uniswap V2/V3, Curve, Balancer, and other major DEX protocols. This tool helps LPs maximize returns while understanding and managing risks like impermanent loss, volatility exposure, and protocol-specific vulnerabilities.

Features

Core Analysis Capabilities

• Real-Time Pool Metrics: TVL, volume, fee generation, utilization rates
• Impermanent Loss Tracking: Continuous IL monitoring with historical analysis
• APY Decomposition: Breakdown of trading fees, farming rewards, and token incentives
• Liquidity Concentration: Uniswap V3 position analysis with range efficiency
• Slippage Modeling: Price impact calculations for various trade sizes
• Risk Scoring: Comprehensive safety assessment including rug pull detection
• Multi-Chain Support: Ethereum, BSC, Polygon, Arbitrum, Optimism, Base

Advanced Features

• Historical Performance: Backtesting LP positions over any time period
• Optimal Range Calculation: For concentrated liquidity positions (V3)
• Rebalancing Signals: Automated alerts when positions drift out of range
• Yield Optimization: Comparison across similar pools for best opportunities
• Gas Cost Analysis: ROI calculations including transaction costs
• Protocol Risk Assessment: Smart contract audits, TVL trends, team transparency

Supported DEX Protocols

Uniswap V2/V3

• Constant product (x*y=k) AMM analysis
• V3 concentrated liquidity position evaluation
• Tick spacing and fee tier optimization
• Historical fee accumulation tracking

Curve Finance

• StableSwap invariant calculations
• Base APY vs CRV/CVX boosted yields
• Gauge weight analysis
• Pool imbalance detection

Balancer V2

• Multi-asset weighted pools
• Custom bonding curves
• Composable stable pools
• Protocol fee analysis

Other Protocols

• SushiSwap (fork analysis)
• PancakeSwap (BSC/Ethereum)
• TraderJoe (Avalanche)
• QuickSwap (Polygon)

Risk Scoring Methodology

Overall Risk Score Calculation (0-100)

The risk score is computed using weighted factors:

Overall Score = (
    Liquidity Score (25%) +
    Volume Score (15%) +
    IL Risk Score (20%) +
    Protocol Score (20%) +
    Rug Pull Score (15%) +
    Smart Contract Score (5%)
) / 6

Individual Risk Components

1. Liquidity Risk (0-100)

   • Score = min(100, TVL / $1M * 100)
   • <$100k TVL = HIGH risk
   • $100k-$1M = MEDIUM risk

   • $1M = LOW risk

2. Volume Risk (0-100)

   • Score = min(100, Daily Volume / $100k * 100)
   • Healthy ratio: Daily Volume > 10% of TVL

3. Impermanent Loss Risk

   • Based on asset correlation and volatility
   • Stablecoin pairs: LOW (90-100 score)
   • Correlated assets: MEDIUM (60-80 score)
   • Uncorrelated: HIGH (0-50 score)

4. Protocol Risk

   • Audited major protocols: 85-95 score
   • Unaudited but established: 60-75 score
   • New/unknown: 30-50 score

5. Rug Pull Risk

   • Liquidity locked: +30 points
   • Team doxxed: +20 points
   • Audited contracts: +25 points
   • Established community: +15 points
   • Time-tested (>6 months): +10 points

Automated Alerts

Alert Triggers

The analyzer generates alerts based on these conditions:

1. Price Range Deviation (Uniswap V3)

   • Alert when current price moves >90% of your range width
   • Recommendation: Rebalance position

2. TVL Drop

   • Alert when TVL drops >20% in 24 hours
   • Severity: HIGH - potential liquidity crisis

3. Impermanent Loss Threshold

   • Alert when IL exceeds -5%
   • Provide IL recovery time estimate based on fee generation

4. Volume Anomalies

   • Alert when 24h volume <10% of historical average
   • May indicate reduced fee generation

5. Smart Contract Events

   • Monitor for ownership transfers
   • Track liquidity lock expiration dates
   • Alert on unusual contract interactions

Best Practices

For Liquidity Providers

1. Start Small: Test pools with 5-10% of intended capital
2. Diversify: Spread across 3-5 pools to reduce risk
3. Monitor Daily: Check positions at least once per day
4. Set Stop Losses: Define IL tolerance before entering (-10% typical)
5. Calculate Break-Even: Know how long fees take to recover IL

Position Management

1. Entry Strategy:

   • Dollar-cost average into positions over 1-2 weeks
   • Enter during low volatility periods
   • Avoid FOMO entries during price spikes

2. Exit Strategy:

   • Define profit targets (e.g., 15% APY)
   • Set maximum acceptable IL (-10% to -15%)
   • Monitor for fundamental changes in protocol

3. Rebalancing (V3):

   • Rebalance when price hits range boundaries
   • Consider gas costs vs additional fees earned
   • Use wider ranges during high gas periods

Gas Cost Considerations

Transaction Costs by Chain

• Ethereum Mainnet: $20-100 per transaction
• Arbitrum/Optimism: $1-5 per transaction
• Polygon: $0.10-0.50 per transaction
• BSC: $0.20-1.00 per transaction

ROI Calculation Including Gas

def calculate_net_roi(investment, apy, gas_costs, holding_period_days):
    """
    Calculate net ROI after gas costs
    """
    # Entry + exit gas
    total_gas = gas_costs['entry'] + gas_costs['exit']

    # Add rebalancing costs for V3
    rebalances = holding_period_days // 14  # Bi-weekly
    total_gas += rebalances * gas_costs['rebalance']

    # Calculate gross returns
    daily_rate = apy / 365 / 100
    gross_returns = investment * daily_rate * holding_period_days

    # Net returns
    net_returns = gross_returns - total_gas
    net_roi = (net_returns / investment) * 100

    return {
        'gross_returns': gross_returns,
        'total_gas_costs': total_gas,
        'net_returns': net_returns,
        'net_roi': net_roi,
        'break_even_days': total_gas / (investment * daily_rate)
    }

Advanced Features

Yield Optimization Strategies

1. Range Order Strategy (V3):

   • Set narrow ranges just below/above current price
   • Capture fees during breakout moves
   • Higher IL risk but 10x+ fee generation

2. Auto-Compounding:

   • Reinvest earned fees back into pool
   • Increases position size over time
   • Account for gas costs

3. Multi-Pool Hedging:

   • LP in ETH/USDC while shorting ETH elsewhere
   • Neutralizes IL while earning fees
   • Requires margin/derivatives access

Troubleshooting

Common Issues

1. High Impermanent Loss

   • Solution: Wait for price reversion or exit if IL exceeds tolerance
   • Consider hedging strategy for future positions

2. Low Fee Generation

   • Solution: Move to higher volume pools or use concentrated liquidity
   • Check if pool incentives have ended

3. Position Out of Range (V3)

   • Solution: Rebalance immediately or accept zero fee generation
   • Consider wider ranges for future positions

4. Rug Pull Concerns

   • Solution: Exit immediately if red flags appear
   • Always research team and audit status before entering

Future Enhancements

• Automated rebalancing bot integration
