What Are Liquidity Pools?
A liquidity pool is a collection of tokens locked in a smart contract that enables trading on decentralized exchanges (DEXs). Instead of using order books like traditional exchanges, DEXs use these pools with an automated market maker (AMM) algorithm.
How It Works
- LPs deposit tokens — You add two tokens in equal value (e.g., $500 PLS + $500 PLSX)
- You receive LP tokens — Represents your share of the pool
- Traders swap against the pool — Paying fees for each trade
- You earn fees — Proportional to your pool share
- Withdraw anytime — Burn LP tokens to receive your share of the pool
💡 Simple Example
You deposit $500 PLS + $500 pHEX into a pool with $10,000 total liquidity. You now own 10% of the pool. When traders pay 0.29% fees, you earn 10% of those fees.

Understanding Impermanent Loss
⚠️ Critical Concept
Impermanent Loss (IL) is the biggest risk in LP. You must understand it before providing liquidity!
What Is Impermanent Loss?
Impermanent Loss occurs when the price ratio between your two tokens changes from when you deposited. The more the prices diverge, the greater the IL.
IL Example
You deposit:
- 1,000 PLS (worth $100)
- 100 PLSX (worth $100)
- Total: $200
PLS doubles in price while PLSX stays flat:
- If you had just held: 1,000 PLS ($200) + 100 PLSX ($100) = $300
- As LP (due to rebalancing): ~707 PLS ($141) + ~141 PLSX ($141) = $282
- IL = $300 - $282 = $18 (6% loss)
IL Chart
| Price Change | Impermanent Loss |
|---|---|
| 1.25x (25% change) | 0.6% |
| 1.5x (50% change) | 2.0% |
| 2x (100% change) | 5.7% |
| 3x (200% change) | 13.4% |
| 4x (300% change) | 20.0% |
| 5x (400% change) | 25.5% |
Why It's "Impermanent"
If prices return to their original ratio, the loss disappears. It only becomes permanent when you withdraw while prices are diverged.
When IL Is Worth It
LP can still be profitable if:
- Trading fees exceed IL
- You're bullish on both tokens long-term
- The pair stays relatively stable
- High trading volume generates strong fee income
Best Pools for Beginners
Low Risk Pools
- PLS/DAI: Stable value on one side reduces IL
- DAI/USDC: Stablecoin pair — minimal IL
Moderate Risk / Higher Returns
- PLS/PLSX: Both native tokens, correlated movement
- PLS/pHEX: High volume, good fees
- PLS/eETH: Popular bridged pair
Higher Risk / Potentially Higher Returns
- New token pairs
- Low liquidity pairs
- Volatile altcoin pairs
Calculating LP Returns
APR Estimation Formula
APR = (Daily Fees × 365) / Total Liquidity × 100
Example Calculation
- Pool has $1,000,000 liquidity
- Daily trading volume: $500,000
- Fee rate: 0.29%
- Daily fees: $500,000 × 0.29% = $1,450
- APR: ($1,450 × 365) / $1,000,000 = 52.9%

LP Strategies
Strategy 1: Set and Forget
Add liquidity to a stable pair and leave it. Check monthly. Best for:
- Beginners
- Small positions
- Passive investors
Strategy 2: Active Management
Monitor positions, remove if IL grows too large, rebalance as needed. Requires:
- Time and attention
- Understanding of market conditions
- Tracking tools
Strategy 3: Compound Regularly
Withdraw fees and add them back to your position. On PulseChain, this is profitable due to low gas:
- Daily compounding: Maximum returns, but time-intensive
- Weekly compounding: Good balance
- Monthly compounding: Minimal effort, still effective
How to Remove Liquidity
- Go to "Pool" on PulseX
- Find your position under "Your Liquidity"
- Click on the position
- Click "Remove"
- Select percentage to remove (25%, 50%, 75%, Max)
- Review tokens you'll receive
- Click "Remove"
- Confirm in MetaMask
- Tokens return to your wallet
LP Risks
1. Impermanent Loss
Covered above — the main risk. Mitigate by choosing correlated pairs.
2. Smart Contract Risk
Bugs in DEX contracts could lead to loss. Mitigate by:
- Using battle-tested protocols (PulseX uses Uniswap V2 code)
- Not putting all funds in one pool
3. Rug Pull Risk
One token in your pair could become worthless. Mitigate by:
- Only LP with established tokens
- Research tokens before LP
- Avoid pairs with unknown tokens
4. Oracle/Price Manipulation
Large swaps or flash loans could exploit your LP. Less common on established pairs.
Frequently Asked Questions
How much can I earn from LP on PulseChain?
Returns vary widely — anywhere from 5% to 100%+ APR depending on the pool, volume, and IL. High-volume pairs like PLS/PLSX typically offer 20-50% APR. Always factor in IL when calculating real returns.
What's the minimum to provide liquidity?
There's no minimum, but very small amounts may not be worth it even on PulseChain. Recommended: at least $100-500 total to make the effort worthwhile.
Can I lose money providing liquidity?
Yes. If IL exceeds your earned fees, you'll have less value than if you had just held the tokens. Additionally, if one token crashes to zero, you'll end up with only that worthless token.
How often should I compound?
On PulseChain, weekly compounding is a good balance. Daily is optimal mathematically but requires more effort. Monthly works fine for smaller positions.
What happens to my LP tokens if PulseX upgrades?
Your LP tokens remain valid. If there's a migration (like V2 to V3), you'll typically need to withdraw from old pools and deposit to new ones.
Conclusion
Providing liquidity on PulseChain is an accessible way to earn passive income from your crypto holdings. The key advantages — ultra-low fees and quick transactions — make it practical for all portfolio sizes. Remember to:
- Understand impermanent loss before starting
