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.

1️ 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

2️ 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

3️ 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

4️ 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.
