# Earning SDEX rewards

The Stellar DEX (SDEX) is Stellar's protocol-level order book for trading classic Stellar assets.

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).

The screenshots below use the LOBSTR mobile app.

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

1. Open the **Orderbook** tab on the market page.
2. Review the current buy and sell offers.
3. Select **Buy** or **Sell** to open the order form.
4. Select **Limit Order**.
5. Enter a price and amount you are willing to trade. Offers closer to the spread generally receive a higher reward score but are also more likely to execute. Do not submit an offer unless you are prepared for it to be filled partially or in full.

### After order submission

1. Review the order parameters and submit the transaction.
2. Return to the **Orderbook** to confirm that the offer is open.
3. Monitor the offer for partial or full fills, and cancel it if you no longer want the remaining amount to trade.

An eligible offer contributes to the hourly reward calculation while it remains on the order book. The score depends on its time on the book, distance from the spread, and fulfillment. Placing an offer does not guarantee a reward, and execution can create market and inventory risk. See [SDEX rewards](/voting-and-rewards/sdex-rewards.md) for the calculation factors.
