CubFinance has no functionality for checking the dollar value of the Farms and Dens of a wallet of yours.
Just a friendly reminder of how it can be done using a simple script with a web interface made by a third party:
You need to go to:
As the Masterchef address you need to enter that of CubFinance, which is
0x227e79C83065edB8B954848c46ca50b96CB33E16
There you go. It is easy to keep tabs of the dollar value of your Dens and Farms using this web page.
As the router address, the website offers Pancakeswap. It works with CubFinance because CubFinance uses Pancakeswap.
Hope this helps.
