# 🌊 | Liquidity Pools

Liquidity Pools are collections of tokens which have been <mark style="color:blue;">**locked by smart contracts**</mark> at the request of their holders.

On Unlimited Leverage, liquidity pools are used in a **trustless bankroll model**, rather than to provide trade liquidity. **This means**:

* Pools <mark style="color:blue;">**earn a percentage**</mark> of the fees accrued
* Pools are used to <mark style="color:blue;">**pay out the profits**</mark> of profitable trades

This is a well-established model within both the DeFi and cryptocurrency gambling ecosystems.&#x20;

As a result, the amount you earn as a liquidity provider is **based on the fees earned** <mark style="color:blue;">**combined**</mark> with **the overall profit & loss of the traders** using the relevant trading pair.&#x20;

**Please note**, providing liquidity can entail a risk of unrealised loss in assets if trader profitability exceeds the fees earned by a pool. &#x20;
