 Although it is a common approach, [calling the GET method](/v3/guidelines/smart-contracts/get-methods#calling-get-methods-from-code) every time to retrieve the wallet address can be slow and resource-intensive. 
 However, if you know the jetton wallet code and storage structure, you can calculate the wallet address without making network requests.

 Using Tonviewer, you can get the jetton master contract address, for example `EQAJ8uWd7EBqsmpSWaRdf_I-8R8-XHwh3gsNKhy-UrdrPcUo`. 
 If we [go to this address](https://tonviewer.com/EQAJ8uWd7EBqsmpSWaRdf_I-8R8-XHwh3gsNKhy-UrdrPcUo?section=method) and open the Methods tab, we can see that there is already a `get_jetton_data` method there. 
 By calling it, we can get the hex form of the cell with the jetton wallet code:
