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.
How Liquidity Pools Work
the mechanics of decentralized trading
Pool
Trade

Provider deposits equal value of two tokens • Receives LP tokens representing share • Tokens locked in smart contract • Example: $500 ETH + $500 USDC
Combined deposits form liquidity pool • x * y = k formula maintains balance • Larger pools = less slippage • Pool depth determines trade capacity
Traders exchange tokens against pool • Price adjusts based on ratio change • Swap fee (0.1-1%) charged • No counterparty needed
Swap fees distributed to all LPs • Proportional to pool share • Additional protocol rewards possible • Withdraw anytime (usually)
Pool Types Comparison
different pool structures for different use cases
Equal value of both tokens • Most common type (Uniswap v2) • Simple IL calculation • Balanced exposure to both assets
Uneven asset ratios • Reduces IL on one side • Used for index-like exposure • Example: Balancer pools
Optimized for pegged assets • Minimal slippage between stables • Very low IL risk • Example: Curve 3pool
LPs choose price ranges • Capital efficiency multiplied • Higher fees in active range • Higher IL if price exits range • Example: Uniswap v3
Deposit one asset only • Protocol pairs with other side • Simpler UX for LPs • IL risk still exists
3+ tokens in one pool • Index fund-like exposure • Complex rebalancing • Example: Balancer 8-token pools
Impermanent Loss Explained
the hidden cost of providing liquidity
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
Pool rebalances to maintain ratio • You sell winner, buy loser automatically • Arbitrageurs extract the difference • The bigger the divergence, the bigger the loss
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
One token moons, other stays flat
One token crashes to zero
High volatility, low volume pools
Withdrawing during maximum divergence
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
Fees earned exceed IL
You wanted exposure to both assets anyway
Prices return to entry ratio
Protocol rewards compensate losses
LP Strategy Guide
how to approach liquidity provision profitably
Stablecoin pairs only (USDC/USDT)
Established pools with high TVL
Minimal IL risk
Lower APY but consistent
Best for: Capital preservation
Blue-chip pairs (ETH/USDC)
High-volume established pools
Moderate IL risk
Fees often offset IL
Best for: Passive yield seekers
New token launches, meme pairs
High APY but high IL risk
Farm and dump approach
Requires active management
Best for: Yield farmers willing to lose
Concentrated liquidity (Uni v3)
Adjust ranges based on price action
Highest capital efficiency
Requires constant attention
Best for: Full-time DeFi participants
