# Aster Code

### **What is Aster Code?**

Aster Code is a broker ecosystem that lets builders collect fees when users trade through their custom interfaces. Builders create their own trading UIs on top of Aster's infrastructure and earn a commission on every executed trade routed through their interface.

### **How Aster Code Works**

To become a builder and start earning fees:

1. **Create an account:** Register using your Web3 wallet address.
2. **Deposit the required amount:** Deposit a minimum of 100 $ASTER into your Aster perps account. The builder must maintain at least 100 $ASTER in their perps wallet throughout the process.
3. **Build your UI:** Create your own trading interface and connect it to Aster Code. You can find the API demo code in the [Aster Code API documentation](https://asterdex.github.io/aster-api-website/asterCode/integration-flow/).
4. **Invite users:** Users trade via your UI page. They must complete both Agent approval and Builder fee approval the first time they trade through your interface.

To view builder fee details: visit the [Aster Code](https://www.asterdex.com/en/aster-code) page and click Builder Center for an overview of your fees and to claim them.

### **Why Use Aster Code?**

* **Fee collection:** Builders reliably earn a builder fee on executed trades (ADL and liquidation orders do not count toward builder fees).
* **Transparent user consent:** Users explicitly approve both the broker (agent) and the maximum builder fee rate.
* **Automated rewards:** Once an order is filled and validated, builder fees are recorded automatically on a daily basis.
* **Simple integration:** The flow fits seamlessly into existing trading steps – users approve the builder and agent during the "Enable Trading" process.
