What is a Liquidity Pool?

A liquidity pool is a smart contract containing paired tokens that users deposit to enable decentralized trading. Instead of traditional order books, decentralized exchanges (DEXs) use liquidity pools to facilitate instant swaps between tokens.

How Liquidity Pools Work

  1. Liquidity providers (LPs) deposit equal values of two tokens
  2. Pool forms: e.g., ETH/USDC pool
  3. Traders swap against the pool
  4. LPs earn fees from each trade
  5. Algorithm determines prices (AMM)

Example

  • You deposit $1,000 ETH + $1,000 USDC
  • Traders swap ETH↔USDC using your liquidity
  • You earn 0.3% of each trade (varies by pool)

Why Liquidity Pools Matter

For Traders

  • Instant swaps without counterparty
  • No need to wait for orders to match
  • Trade 24/7 without intermediaries

For Providers

  • Earn passive income from fees
  • No minimum deposit requirements
  • Exit anytime (usually)

Liquidity Pool Risks

Impermanent Loss

When token prices change significantly:

  • Your LP position may be worth less than holding
  • Called “impermanent” because it reverses if prices return

Smart Contract Risk

  • Bugs can lead to fund loss
  • Hacks have drained pools

Rug Pulls

  • Malicious pools can steal funds
  • Stick to established protocols
  • Uniswap: Largest Ethereum DEX
  • PancakeSwap: BNB Chain leader
  • Curve: Stablecoin specialist

For centralized alternatives, try Binance or Coinbase.
