Single-Sided vs. Dual-Sided Liquidity: A Quick DeFi LP Guide for Beginners

When using Uniswap V3 or similar AMMs to provide liquidity, you’ll often hear the terms “single-sided liquidity” and “dual-sided liquidity.” What exactly are they, and when should you use each? Let’s break it down clearly.

1️⃣ What is Dual-Sided Liquidity?

Dual-sided liquidity is the most common form of liquidity provision:

  • You deposit two tokens (e.g., ETH-USDC) simultaneously.
  • Within your specified price range, the pool will automatically swap between the two assets as the price moves, earning you fees.
  • When the price sits in the middle of your range, you hold a combination of both assets.

Pros:
✅ Provides stable depth and fee earnings
✅ Ideal for those willing to hold both assets

Cons:
⚠️ Exposed to impermanent loss
⚠️ Not suitable if you only want to hold a single asset

2️⃣ What is Single-Sided Liquidity?

Single-sided liquidity means providing liquidity with only one token (e.g., only USDC), using price ranges on Uniswap V3 or similar range-based AMMs:

  • If your price range is entirely above the current price (e.g., range ETH 3200-3500 while ETH is 3000):

    • You will hold only USDC (Token0).
    • If the price rises into your range, your assets will start converting into ETH, earning fees.

  • If your price range is entirely below the current price (e.g., range ETH 2500-2800 while ETH is 3000):

    • You will hold only ETH (Token1).
    • If the price drops into your range, your ETH will start converting to USDC, earning fees.

Pros:
✅ Allows you to hold only the asset you prefer
✅ Lets you wait for a price trigger to earn fees

Cons:
⚠️ If the price never touches your range, you earn no fees
⚠️ Once the price enters your range, impermanent loss still occurs

3️⃣ Single-Sided vs. Dual-Sided: How to Choose?

Scenario Suggested Strategy
Want stable fee income and can hold both assets Dual-sided liquidity
Want to hold only one asset while waiting to earn fees Single-sided liquidity
Want to gradually swap assets on price moves Single-sided liquidity

4️⃣ Key Considerations

✅ Single-sided liquidity requires your price range to be entirely above or below the current price; otherwise, it will become dual-sided.
✅ Even with single-sided liquidity, once the price enters your range, your assets will start swapping, and you’ll begin earning fees while your portfolio composition changes.
✅ Always monitor impermanent loss and realistic APR expectations when providing liquidity.
