In order to repay a loan and withdraw collateral, make sure you have the required amount of MONEY to clear all the debt. Your minting fee is charged in MONEY, so you may have to acquire some MONEY from our curve pool (link on the page) to extinguish your entire debt. It is also possible to make partial repayment, withdrawing only part of the collateral.
Click on 'Repay' to access the appropriate component and click on 'max' to use the total wallet MONEY balance for the repayment.
