# SDEX Rewards

SDEX rewards are earned by **placing buy and sell offers** on the **order books** of eligible markets. This can be done using **SDEX exchange interfaces** such as [**StellarX**](https://www.stellarx.com/) and [**StellarTerm**](https://stellarterm.com/). For information on **AMM pool rewards for liquidity providers**, please refer to the **AMM rewards section**.

#### **Important Note:**

To receive rewards, you **must add a trustline to AQUA** in your Stellar wallet. Without it, rewards will not be credited.
{% endhint %}

#### **How Rewards Are Distributed**

Rewards are calculated based on the following factors:

* **Trade Volume** – The total volume of each offer in a market.
* **Time in Order Book** – The duration an offer remains active.
* **Proximity to Spread** – How close an offer is to the market spread.
* **Offer Execution** – Orders that are successfully fulfilled.

Considering these factors, rewards are automatically distributed **every hour** to eligible participants. The **more liquidity** provided and the **closer the offers are to the spread**, the **higher the rewards**.
