# Websocket Connection

### **Important Note:**

For all the Websocket endpoints below, pass your profile address.

To track your transactions on-chain (e.g., via **Aptos Explorer** or **Aptos Scan**), you must use your **profile address**, as all on-chain trades are executed using this profile address.

To obtain your profile address, use the `/getProfileAddress` endpoint and provide your wallet address as the `userAddress` parameter.

### How to Fetch the Profile Address:

**Example endpoint:**\
<https://perps-tradeapi.kanalabs.io/getProfileAddress?userAddress=0xd01e3a233632a41463bd6d289e99e69e1b50815c7afff710e1c992659a8722f3>\
\
**Example code:**\
