When you deposit funds to your Sivo Cash account, your Sivo Debt line is activated.

You can view deposited funds once they arrive under the Debt Lines tab by looking at the Loss Reserve widget in the top right.

Cash account represents your deposits that have not yet been locked as loss reserve.
Cash locked represents your deposits that have been locked as loss reserve.

Once cash is received and locked, it can be used to draw down on the line, increasing your usage. Your usage can be viewed in the top left widget on the same page.
