How Does a Liquidity Pool Work?
A liquidity pool (LP) is a smart contract that holds two tokens (e.g., MOE and MNT) to facilitate decentralized trading. Unlike centralized exchanges that rely on market makers, decentralized exchanges (DEXs) use automated market makers (AMMs)—algorithms embedded in smart contracts—to execute trades automatically and permissionlessly.
By locking tokens into a pool, users enable seamless token swaps without intermediaries, ensuring 24/7 liquidity for traders.

Benefits of Depositing Liquidity
Earn Trading Fees
- Provide token pairs (e.g., MOE/MNT) to an LP ("adding liquidity").
- Receive LP tokens representing your share.
- Earn 0.25% of all trades in the pool, proportional to your stake.
- Fees accrue in real-time and are claimed upon withdrawal.
Pool APR
- APR (Annual Percentage Yield) reflects earnings from trading fees.
- Yield compounds as fees are reinvested into the pool.
Risks of Liquidity Provision
Impermanent Loss (IL)
Impermanent loss is the temporary value reduction when providing liquidity vs. holding assets. It arises from price volatility in the pool.
How IL Occurs:
- Price Imbalance: When the price ratio of pooled tokens shifts.
- AMM Adjustments: The AMM rebalances holdings to maintain pool ratios, potentially selling more of the appreciating asset.
- Loss Realization: IL reverses if prices return to initial ratios. If not, loss becomes permanent upon withdrawal.
Example: If MOE doubles in value vs. MNT, the AMM sells MOE to balance the pool, reducing your potential gains vs. holding MOE outright.
Mitigating IL:
- Choose stable pairs (e.g., stablecoins) to minimize volatility.
- Monitor pool performance and withdraw during price stability.
FAQ
1. Is providing liquidity profitable despite IL?
Yes, if trading fees outweigh IL. High-volume pools often offset losses.
2. Can IL be avoided completely?
No, but stablecoin pairs (e.g., USDC/USDT) reduce IL risk significantly.
3. How are LP tokens used?
They represent your liquidity share and can be staked in yield farms for additional rewards.
4. When should I withdraw liquidity?
During price stability or when fees no longer compensate for IL.
5. Do all AMMs have the same fee structure?
No—some pools charge 0.3% (e.g., Uniswap), while others adjust fees based on volatility.
Key Takeaways
- Liquidity pools power decentralized trading via AMMs.
- Providers earn fees but face impermanent loss from price shifts.
- APR and token selection critically impact profitability.
