### Dynamic Address

The Bitcoin deposit address of each merchant is a dynamic address. These addresses can be queried through the contract as follows.

#### Step 1 : Query FBTC Address of Each Qualified User

1. Open your web browser and go to [this page](https://etherscan.io/address/0xbee335BB44e75C4794a0b9B54E8027b111395943#readProxyContract#F12).
2. Scroll down to find the method `12. getQualifiedUsers` and click to expand it.
3. Click the `Query` button to call the `getQualifiedUsers` method. This will return an array containing all the merchants' FBTC addresses.

3. Click the `Query` button to call the `getQualifiedUserInfo` method. This will return the detailed information for the merchant, including their corresponding BTC deposit address.
