Liquidity Pools 101
💧 Liquidity Pools 101
Liquidity pools are the foundation of decentralized exchanges (DEXs) like XDEX. They enable seamless token swaps, drive fair price discovery, and offer rewards to liquidity providers (LPs). By contributing tokens to a pool, users help power the protocol while earning a share of trading fees.
🌀 What Is a Liquidity Pool?
A liquidity pool is a collection of tokens locked in a smart contract that facilitates trading between token pairs. Instead of relying on traditional buyers and sellers, trades are executed directly against the pool’s reserves.
🔁 Example:
In a Token A / Token B pool:
The pool holds reserves of both tokens
Traders can swap Token A for Token B, or vice versa
LPs supply equal-value amounts of both tokens, enabling the swaps
⚙️ How Do Liquidity Pools Work?
XDEX uses the Constant Product Market Maker (CPMM) model to manage pool balances:
x * y = kx = Reserve of Token A
y = Reserve of Token B
k = Constant product (doesn’t change during swaps)
📊 Example:
If a pool starts with 100 Token A and 100 Token B, and a trader swaps 10 Token A for Token B,
the pool updates to approximately 110 Token A and 90.91 Token B — keeping k constant.
🧠 Why Are Liquidity Pools Important?
Seamless Trading Tokens can be exchanged at any time — no need for matching buyers or sellers.
Decentralized Price Discovery Prices are updated automatically based on the pool’s reserves.
Efficient Markets Deep liquidity reduces slippage and improves execution quality for all users.
💰 Benefits for Liquidity Providers (LPs)
LPs help keep markets liquid by depositing tokens into pools. In return, they earn rewards:
Trading Fees A portion of every swap (0.25%) is distributed to LPs based on their share of the pool.
LP Tokens Represent your pool share — redeemable anytime for your share of the pool’s assets.
Passive Income Earn rewards automatically without the need to actively manage positions.
🔁 Maker fees are automatically compounded into the pool, increasing the value of LP tokens over time.
⚠️ Risks of Liquidity Provision
While LPing offers potential rewards, it's important to understand the risks:
Impermanent Loss Occurs when the price of tokens in the pool diverge significantly — LP value may decrease vs simply holding the tokens.
Smart Contract Risk Pools are powered by smart contracts, which could be vulnerable to bugs or exploits.
🛡️ How XDEX Helps Mitigate Risk

Targeted incentives to reward LPs for participating in early or volatile pools
