# Fees

### Overview

The continuous operation of an exchange relies on the collection of various fees. These fees are not only used for the exchange's operations, development, and security, but also for safeguarding user funds and improving services. A reasonable fee structure can maintain stable exchange operations while providing users with a better trading experience and a safer trading environment.

In order to better serve users, we can design products with the explicit goal of reducing exchange fees, which is highly beneficial for users. Advantages such as low transaction fees, no hidden costs, and no trading slippage will allow users to enjoy a lower-cost trading experience, increasing their profits and satisfaction.

Currently charged fees can be divided into three main categories based on different functions: Trading, Liquidity, and Wallet.
