Uniswap V2 vs V3: Complete Comparison for Liquidity Providers

Uniswap is the largest decentralized exchange on Ethereum, with over $5 billion in total value locked. While Uniswap V2 pioneered the automated market maker (AMM) model, V3 introduced revolutionary concentrated liquidity features. But which version should you use as a liquidity provider?

This comprehensive guide compares Uniswap V2 and V3 across all key dimensions to help you make an informed decision.

TL;DR - Quick Comparison

| Feature | Uniswap V2 | Uniswap V3 | |---------|-----------|-----------| | Liquidity Range | Full range (0 to ∞) | Concentrated (custom ranges) | | Capital Efficiency | Low | Up to 4000x higher | | Fee Tiers | Fixed 0.3% | 0.01%, 0.05%, 0.3%, 1% | | Impermanent Loss Risk | Moderate | Higher (in range) | | Management Required | Passive | Active monitoring needed | | Gas Costs | Lower | Higher | | Best For | Set-and-forget LPs | Active traders, market makers | | APY Potential | 5-30% typically | 20-200%+ for active LPs |

Understanding the Core Difference: Full Range vs Concentrated Liquidity

Uniswap V2: Full Range Liquidity

In Uniswap V2, when you provide liquidity, your capital is distributed across the entire price curve from $0 to infinity.

Example: If you deposit 1 ETH + 2,000 USDC when ETH = $2,000:

• Your liquidity is active regardless of ETH price
• You earn 0.3% fee on all trades
• Your position is always "in range"
• Capital efficiency is spread thin

Visual representation:

Price Range: [━━━━━━━━━━━━━━━━━━━━━━]
Your Liquidity: ████████████████████████
Active Range: ████████████████████████ (100%)

Uniswap V3: Concentrated Liquidity

V3 lets you concentrate your liquidity within a specific price range you choose.

Example: Same 1 ETH + 2,000 USDC, but you set range $1,800 - $2,200:

• Your liquidity only active within this range
• You earn fees ONLY when price is in range
• Can achieve up to 4000x capital efficiency
• Requires active management

Visual representation:

Price Range: [━━━━━━━━━━━━━━━━━━━━━━]
Your Liquidity:      ████████
Active Range:        ████████ (20% of curve)
                     ↑
                Current Price

Capital Efficiency: The Game-Changer

V2 Capital Efficiency

With V2's full-range approach:

• Only ~20-30% of your capital is typically utilized
• Most liquidity sits idle at extreme prices
• Lower fee earnings per dollar invested

Example calculation:

• Deposit: $10,000 in ETH/USDC pool
• Daily volume: $1,000,000
• Your share: 0.1% of pool
• Daily fees: $1,000,000 × 0.3% × 0.1% = $3/day
• Annual APY: ~11%

V3 Capital Efficiency

With concentrated liquidity:

• 100% of your capital can be utilized if price stays in range
• Much higher fee earnings per dollar
• Can provide same liquidity with less capital

Example with same setup but tight range:

• Deposit: $10,000 in narrow range
• Effective liquidity: $50,000 (5x multiplier)
• Your effective share: 0.5% of pool
• Daily fees: $1,000,000 × 0.3% × 0.5% = $15/day
• Annual APY: ~55% (5x better!)

Efficiency Multiplier by Range Width

| Price Range Width | Efficiency Multiplier | Risk Level | |-------------------|----------------------|------------| | ±2% (very tight) | 100-200x | Extreme | | ±5% (tight) | 20-40x | High | | ±10% (moderate) | 10-20x | Moderate | | ±25% (wide) | 3-5x | Low | | ±50% (very wide) | 1.5-2x | Very Low | | Full range (V2 equivalent) | 1x | Lowest |

Fee Structure Comparison

Uniswap V2: One Size Fits All

• Single fee tier: 0.3% per swap
• Distribution: 100% to liquidity providers
• No flexibility: Same rate for all pairs

Pros:

• Simple and predictable
• Good middle ground for most pairs

Cons:

• Not optimal for stablecoins (too high)
• Not ideal for exotic pairs (too low)

Uniswap V3: Multiple Fee Tiers

V3 introduced four fee tiers to match different pool characteristics:

0.01% tier:

• Best for: Stablecoin pairs (USDC/USDT, DAI/USDC)
• Volatility: Extremely low
• Volume: Very high
• Strategy: Tight ranges (±0.5%)

0.05% tier:

• Best for: Correlated pairs (WETH/stETH, WBTC/renBTC)
• Volatility: Low
• Volume: High
• Strategy: Narrow ranges (±2-5%)

0.3% tier:

• Best for: Standard pairs (ETH/USDC, ETH/DAI)
• Volatility: Moderate
• Volume: Medium-high
• Strategy: Moderate ranges (±10-20%)

1% tier:

• Best for: Exotic/volatile pairs (new tokens, low-cap)
• Volatility: High
• Volume: Lower
• Strategy: Wide ranges (±30-50%)

Fee Earnings Comparison Example

ETH/USDC pair with $1M daily volume:

Uniswap V2 scenario:

• Fee tier: 0.3%
• Total fees: $3,000/day
• Your share (1% of pool): $30/day

Uniswap V3 scenario (optimal):

• Fee tier: 0.3%
• Total fees: $3,000/day
• Your concentrated position: Equivalent to 8% of pool
• Your earnings: $240/day (8x better!)

But this assumes price stays in your range 100% of the time.

Impermanent Loss: The Trade-off

V2 Impermanent Loss

In V2, impermanent loss is predictable and follows a standard curve:

IL by price change:

• 1.25x change: 0.6% loss
• 1.5x change: 2.0% loss
• 2x change: 5.7% loss
• 3x change: 13.4% loss
• 4x change: 20.0% loss

Characteristics:

• Gradual and predictable
• Occurs across entire price range
• Partially offset by fees over time

V3 Impermanent Loss

V3 IL is more complex due to concentrated ranges:

Within your range:

• IL behaves similarly to V2
• But concentrated, so potentially higher magnitude
• Higher fees help offset losses

Outside your range:

• Position becomes 100% one token
• All price movement is impermanent loss
• No fees earned to offset losses
• Must manually rebalance

Example scenario:

You provide liquidity ETH/USDC with range $1,800-$2,200 at current price $2,000.

If ETH rises to $2,500:

• Your position exits range at $2,200
• You now hold 100% USDC
• You missed ETH gains from $2,200 to $2,500
• This is additional IL compared to V2

If ETH falls to $1,500:

• Your position exits range at $1,800
• You now hold 100% ETH
• You're exposed to full downside
• No fees earned below $1,800

IL Risk Management

V2 approach:

• Set and forget
• Earn fees on all trades
• Accept moderate IL

V3 approach:

• Choose wider ranges for less IL risk
• Monitor and rebalance regularly
• Use multiple positions at different ranges
• Accept higher IL for higher fees

Gas Costs: An Important Factor

V2 Gas Efficiency

Operations and typical gas costs:

• Add liquidity: ~120,000 gas (~$25 at 50 gwei)
• Remove liquidity: ~100,000 gas (~$20 at 50 gwei)
• Collect fees: Free (included in removal)

Total for round trip: ~$45

V3 Gas Costs

Operations are more expensive:

• Add liquidity: ~180,000 gas (~$35 at 50 gwei)
• Remove liquidity: ~140,000 gas (~$28 at 50 gwei)
• Collect fees: ~80,000 gas (~$16 at 50 gwei)
• Rebalance (remove + add): ~$79

Total for round trip + one fee collection: ~$79

For active management (monthly rebalancing):

• Initial deposit: $35
• 4 rebalances per month: $316
• Monthly fee collections: $64
• Total monthly gas: ~$415

This means V3 strategies only make sense for larger positions (>$10,000).

Active vs Passive Management

Time commitment: 5 minutes per month

• Add liquidity once
• Check performance occasionally
• Remove when desired

Best for:

• Busy professionals
• Long-term holders
• Risk-averse investors
• Smaller positions (<$5,000)

V3: The Active Approach

Time commitment: 2-5 hours per week

• Research optimal ranges
• Monitor price movements
• Rebalance positions
• Optimize fee tier selection
• Track multiple positions

Best for:

• Active traders
• Larger positions (>$10,000)
• Professional market makers
• Those seeking maximum returns

• Place liquidity at $1,600-$1,800
• When price drops, you buy ETH with your USDC
• Earn fees during the process

Strategy 3: Just-in-Time Liquidity

For advanced users with bots:

• Add liquidity right before large swaps
• Remove immediately after
• Minimize IL exposure
• Maximize fee capture

Note: Requires technical expertise and infrastructure

Q: What happens to my V2 liquidity? V2 pools still function normally. Your V2 positions are not affected by V3 launch.

Q: Is V3 always better? No. For small positions and passive strategies, V2 often performs better due to lower gas costs and less management overhead.

Q: How often should I rebalance V3 positions? Depends on your range width and volatility. Tight ranges may need weekly rebalancing, wide ranges monthly or less.

Q: What's the minimum position size for V3? Recommended >$10,000 for active strategies due to gas costs. Stablecoin pairs can work with >$5,000.
