# 2. Connecting Upland Account

> Why is that?

The applications that have transactions involved may earn assets. Eg.: 

1. Games that charge players to play.
2. Trade's fee.
3. External market purchased in UPX.

Those assets will be owned by this Upland account connected with the developer account.

{% hint style="warning" %}
Your Sandbox/Playground Upland account can only be connected with your Sandbox/Playground Developer account. 

Your Production Upland account can only be connected with your Production Developer account.
