# Earning SDEX rewards

The Stellar DEX (SDEX) is Stellar's built-in decentralized exchange. SDEX has been at the heart of Stellar since its inception, allowing users to trade tokens within the network, creating a decentralized marketplace at the protocol level.

SDEX rewards incentivize placing offers onto order books of markets chosen by AQUA holders through liquidity voting. Every hour market makers get rewarded AQUA tokens based on how much liquidity they have held on the order books, with filled offers gaining higher rewards than those remaining unfulfilled.

Offers are created on the Stellar ledger as follows.

## Creating offers for the Stellar ledger

Offer creation happens through Stellar user interfaces (Stellar UIs). Popular UIs include [LOBSTR wallet](https://lobstr.co/), as well as web clients: [StellarX](https://www.stellarx.com/markets), [StellarTerm](https://stellarterm.com/markets/), [Stellarport](https://stellarport.io/exchange) and [Lumenswap](https://obm.lumenswap.io/market).

In this quick guide, we are using the LOBSTR mobile app.

### How to get to the trade section and select markets

1. Head to the LOBSTR app and click the ≡ symbol in the top left corner.
2. Click on Trade.
3. Select the market you would like to trade on from the list.

### How to view the current order book, decide your buy/sell price and submit an order

1. On the market overview page select the Orderbook tab
2. View both the buy & sell side of the order book for the selected market to view prices already available for the market.
3. Once you have seen the order book and know what others are currently offering, press the BUY or SELL button to open the trade screen.
4. If you want to provide liquidity (and get rewarded) you should select the Limit order option.
5. Make sure that your limit price (specified in the Price field) is "far" from the market enough that your order doesn't get executed immediately but not too "far" from the market price.

### After order submission

1. After you have specified all the order parameters and submitted the order you will have to wait a bit until the transaction is through.
2. After the order is placed you'll get back to the Orderbook and see a notification that the order is there
3. After it's filled you'll receive another notification.

All you need to do now is allow your assets to sit on the order books for other Stellar users to take. You will receive hourly rewards while your assets sit on the order books based on how long your assets have sat there & how close to the market spread they are. If other users fully or partially fill your offers, you will receive an increased hourly SDEX reward for your contribution to liquidity for the market.
