Decentralized finance (DeFi) continues to evolve, and one of the most powerful innovations in this space is the concept of liquidity pools. At the heart of platforms like PancakeSwap lies the ability for users to provide liquidity and earn rewards—both in trading fees and yield farming. With the transition from Exchange V2 to V3, liquidity provision has become more efficient, customizable, and rewarding.
This guide breaks down everything you need to know about liquidity pools on PancakeSwap, including how they work in both V2 and V3, the benefits of concentrated liquidity, fee structures, and key risks like impermanent loss.
Understanding Liquidity Pools
A liquidity pool is a crowdsourced reserve of tokens locked in a smart contract that enables seamless cryptocurrency trading on decentralized exchanges (DEXs). Instead of relying on traditional order books, decentralized platforms use automated market makers (AMMs), where prices are determined by mathematical formulas based on the ratio of assets in the pool.
When you contribute tokens to a liquidity pool, you become a liquidity provider (LP) and earn a portion of the trading fees generated whenever users swap tokens using that pool.

PancakeSwap Exchange V3: The Future of Liquidity
PancakeSwap’s Exchange V3 introduces a groundbreaking upgrade: non-fungible liquidity positions. Unlike the uniform distribution model in V2, V3 allows LPs to have granular control over where their capital is deployed—making capital efficiency a top priority.
Non-Fungible Liquidity Positions
In V3, every liquidity position is represented as a Non-Fungible Token (NFT). This means each position is unique and contains specific parameters such as:
- Token pair
- Price range
- Fee tier
- Deposit amounts
These NFTs are fully transferable, meaning you can send or trade your liquidity position just like any other NFT. They also represent ownership of the underlying assets and accumulated trading fees.
One major change in V3 is that fees are no longer automatically compounded. Instead, you must manually claim them from your position details page. While this adds a step, it gives you full control over when and how you reinvest or withdraw earnings.
You can remove your liquidity at any time, redeeming your share of the pool’s assets plus any unclaimed fees.
Active Liquidity and Custom Price Ranges
V3 introduces the concept of active liquidity, which only functions when the market price stays within a user-defined range.
For example:
- If you set a price range of 2 to 12.5 USDT per CAKE, your liquidity will only be used when the CAKE price falls between those values.
- If the price moves outside this range, your position becomes inactive, meaning it holds only one token (either CAKE or USDT) and stops earning fees.
This dynamic ensures that your capital isn’t diluted across irrelevant price levels, focusing instead on areas where trades are most likely to occur.
Concentrated Liquidity: Maximizing Capital Efficiency
The standout feature of V3 is concentrated liquidity—the ability to allocate your capital within a specific price range rather than across an infinite curve.
Here’s why it matters:
Baller and Claire both invest $1,000 worth of assets into the CAKE/USDT pool. The current price of CAKE is 5 USDT.
- Baller uses the traditional V2 method, depositing $500 in USDT and 100 CAKE across the full price range.
- Claire uses V3’s concentrated liquidity, setting a price range from 2 to 12.5 USDT per CAKE. She deposits only $370 (185 USDT + 37 CAKE), leaving $630 free for other investments—like locking CAKE in Syrup Pools for additional yield.
As long as CAKE trades between 2 and 12.5 USDT, both earn the same trading fees, but Claire used significantly less capital.
This means higher fee returns per dollar invested, improved capital efficiency, and greater flexibility in portfolio management.

Trading Fees in V3
In PancakeSwap V3, trading fees vary depending on the pool's fee tier. When users swap tokens, they pay a fee ranging from 0.01% to 1%, based on volatility and demand:
- 0.01%: Stablecoin pairs (e.g., USDT/USDC)
- 0.05%: Low-volatility pairs
- 0.30%: Standard pairs (e.g., CAKE/BNB)
- 1.00%: Exotic or high-risk pairs
Fees are distributed proportionally to active liquidity providers within the current price range. This creates a competitive environment where LPs strategically place their capital to capture maximum fee volume.
Earning Additional Yield with CAKE Farms
Providing liquidity isn’t just about earning trading fees—you can also boost returns through CAKE Farms.
By staking your V3 NFT liquidity positions or V2 LP tokens in designated farms, you earn additional CAKE rewards on top of trading fees. This dual-income model makes yield farming one of the most attractive aspects of participating in PancakeSwap’s ecosystem.
Even though V3 is now live, V2 remains operational for certain pairs. Some legacy pools still operate under the old system and offer corresponding V2 Farms. Always check the tags on each pool to confirm which version you're interacting with.
PancakeSwap Exchange V2: The Original Model
Before V3, PancakeSwap operated on a simpler AMM model similar to Uniswap V2.
LP Tokens and Proportional Ownership
When you deposited two tokens—say, CAKE and BNB—into a liquidity pool, you received CAKE-BNB LP tokens in return. These fungible tokens represented your share of the total pool.
For example:
- If you contributed 1% of the total assets in the CAKE-BNB pool, you received 1% of the total LP tokens.
- You could redeem your underlying assets at any time by burning these LP tokens.
Fixed Trading Fees
In V2, every trade incurred a fixed 0.25% fee, with 0.17% going directly back into the liquidity pool as rewards for providers. The remaining portion covered protocol expenses and buybacks.
While less flexible than V3, this model was simple and reliable—ideal for beginners entering DeFi.
What Is Impermanent Loss?
One of the biggest risks in providing liquidity is impermanent loss (IL)—the temporary reduction in value when holding tokens in a liquidity pool compared to simply holding them in your wallet.
As explained by Nate Hindman:
“Simply put, impermanent loss is the difference between holding tokens in an AMM and holding them in your wallet.”
This occurs due to price divergence between the two assets in a pair. For example:
- You deposit equal values of CAKE and BNB.
- If CAKE’s price surges 50%, arbitrage traders will buy it cheaply from the pool, altering the ratio.
- When you withdraw, you may receive fewer CAKE tokens than expected—and more BNB—resulting in a net loss compared to HODLing.
The greater the price swing, the higher the potential IL. However, consistent trading fees can offset or even exceed these losses over time—especially in high-volume pools.

Frequently Asked Questions (FAQ)
What are liquidity pools?
Liquidity pools are smart contracts containing locked tokens that enable automated trading on decentralized exchanges. Users provide funds to these pools and earn fees in return.
How does V3 improve upon V2?
V3 introduces concentrated liquidity, allowing providers to set custom price ranges for higher capital efficiency. It also replaces fungible LP tokens with NFT-based positions for greater flexibility.
Can I lose money providing liquidity?
Yes—due to impermanent loss and market volatility. However, high trading volumes and yield farming opportunities can help offset these risks and generate net profits.
Are V3 NFTs tradable?
Yes. Each liquidity position in V3 is an NFT that can be transferred or sold, giving you full ownership rights over your deposited assets and earned fees.
Do I have to claim fees manually in V3?
Yes. Unlike V2, where fees were automatically reinvested, V3 requires you to manually claim trading fees from your position dashboard.
Should I use V2 or V3?
Use V3 if you want greater control and capital efficiency. Stick with V2 if you prefer simplicity or are participating in legacy farms not yet upgraded.
Final Thoughts
PancakeSwap’s evolution from V2 to V3 marks a significant leap forward in DeFi innovation. With concentrated liquidity, customizable price ranges, and NFT-based positions, users now have unprecedented control over their capital deployment.
Whether you're a seasoned yield farmer or new to DeFi, understanding how liquidity pools work—and how to optimize your strategy—is essential for maximizing returns while managing risk.
As the ecosystem grows, so do the opportunities to earn passive income through smart participation. Stay informed, diversify wisely, and always assess impermanent loss against potential gains.
