# Managing a vault

Go to the vaults page and pick a collateral to open a vault.

A vault has an amount of collateral deposited and some amount of debt minted that eventually needs to be repaid.

In your vault page, there is a box to deposit and withdraw collateral, a box to mint or repay some RoeUSD debt, and a box with stats.

You can deposit collateral to increase your collateral to debt ratio (CDR).
