Liquidity Pool
Market Component
smart contract reserves powering decentralized trading
Liquidity Pool is a smart contract-based reserve of token pairs used to enable decentralized trading, yield generation, and protocol functions on automated market makers (AMMs). Liquidity providers (LPs) deposit equal-value pairs of assets (e.g., $FLR/$sFLR, $XRP/$RLUSD) into the pool, which allows permissionless token swaps. In return, LPs receive a share of swap fees, protocol rewards, or governance incentives.
Use Case: Liquidity pools are critical to DEXs like Uniswap or BlazeSwap. For example, a user deposits $AVAX and $USDC into a pool and receives LP tokens, earning passive yield from trading activity in that pool without needing to manage order books or trades directly.
Key Concepts:
- LP Tokens — Represent a provider’s share of the pool and can be staked for added rewards
- Swap Fee — A small fee taken from each trade and paid to LPs
- Impermanent Loss — Risk LPs face when asset prices shift unevenly
- Pool Weighting — Determines how much of each asset is held (e.g., 50/50, 80/20)
- AMM — Automated market maker protocol that uses pools instead of order books
- Slippage Risk — Price impact when trades are large relative to pool depth
- Yield Farming — Strategy of moving LP positions to maximize rewards
- DeFi Risk — Smart contract vulnerabilities and rug pull exposure in pools
Summary: Liquidity pools are foundational to decentralized finance, replacing traditional order books with automated vaults that support swaps, yield farming, and protocol liquidity. Understanding their structure, risks, and incentives is essential for navigating the DeFi landscape.

Step 1: LP Deposits
Provider deposits equal value of two tokens • Receives LP tokens representing share • Tokens locked in smart contract • Example: $500 ETH + $500 USDC

Step 2: Pool Creation
Combined deposits form liquidity pool • x * y = k formula maintains balance • Larger pools = less slippage • Pool depth determines trade capacity

Step 3: Traders Swap
Traders exchange tokens against pool • Price adjusts based on ratio change • Swap fee (0.1-1%) charged • No counterparty needed

Step 4: LPs Earn
Swap fees distributed to all LPs • Proportional to pool share • Additional protocol rewards possible • Withdraw anytime (usually)
Swap fees distributed to all LPs • Proportional to pool share • Additional protocol rewards possible • Withdraw anytime (usually)
The Trade-Off: LPs earn fees but face impermanent loss if prices diverge. High-volume pools with stable pairs (stablecoin pairs) offer safer returns. Volatile pairs offer higher fees but higher IL risk.
Pool Types Comparison
different pool structures for different use cases
Standard 50/50 Pool
Equal value of both tokens • Most common type (Uniswap v2) • Simple IL calculation • Balanced exposure to both assets

Weighted Pools (80/20)
Uneven asset ratios • Reduces IL on one side • Used for index-like exposure • Example: Balancer pools

Stableswap Pools
Optimized for pegged assets • Minimal slippage between stables • Very low IL risk • Example: Curve 3pool

Concentrated Liquidity
LPs choose price ranges • Capital efficiency multiplied • Higher fees in active range • Higher IL if price exits range • Example: Uniswap v3

Single-Sided Pools
Deposit one asset only • Protocol pairs with other side • Simpler UX for LPs • IL risk still exists

Multi-Asset Pools
3+ tokens in one pool • Index fund-like exposure • Complex rebalancing • Example: Balancer 8-token pools

Selection Guide: Stableswap for stable pairs (lowest risk). Standard 50/50 for volatile pairs with high volume. Concentrated for active management and max capital efficiency. Weighted for directional exposure.
Impermanent Loss Explained
the hidden cost of providing liquidity
What Is Impermanent Loss?
Loss compared to simply holding both tokens • Occurs when prices diverge from entry • “Impermanent” because it reverses if prices return • Becomes permanent when you withdraw

Why Does It Happen?
Pool rebalances to maintain ratio • You sell winner, buy loser automatically • Arbitrageurs extract the difference • The bigger the divergence, the bigger the loss

IL by Price Change
1.25x price change = 0.6% IL
1.5x price change = 2.0% IL
2x price change = 5.7% IL
3x price change = 13.4% IL
5x price change = 25.5% IL

When IL Hurts Most
One token moons, other stays flat
One token crashes to zero
High volatility, low volume pools
Withdrawing during maximum divergence

How to Minimize IL
Choose correlated pairs (ETH/stETH)
Provide to stablecoin pools
Select high-volume pools (fees offset IL)
Use weighted pools for directional bias
Don’t withdraw during divergence

When IL Doesn’t Matter
Fees earned exceed IL
You wanted exposure to both assets anyway
Prices return to entry ratio
Protocol rewards compensate losses

Reality Check: IL is often overstated as a concern. High-volume pools with trading fees frequently outperform holding. Calculate expected fees vs IL before dismissing LP opportunities—many pools are net positive despite IL.

Golden Rule: Only LP with tokens you’re happy to hold long-term regardless of which one appreciates. If you’d be upset holding more of one token after divergence, that pool isn’t for you.

Safety First: Start small with any new pool. Test deposits and withdrawals with minimum amounts before committing significant capital. The highest APYs are often the highest risks—if it seems too good, it probably is.
