Yes, you can. Borrowers get control over their locked assets. For instance, if you can see that your collateral coin is crashing, you request liquidation and repay your loan before the coin loses its liquidity.
Here's how it works:
First, go to My Loans and start a payoff process for an active borrowed loan. You can choose between a Regular Scheduled Payment and a Full Early Repayment.
Choose the one you like and click on the Use Loan Collateral repayment option, as shown in Figure 1 below. Payout will happen at the cost of your collateral. Please be careful, payments made with collateral increase the LTV of an active loan and the risk of collateral liquidation in case of market fluctuations.
If you make a full early repayment with collateral, the rest of the collateral remained after repayment will be credited to your account.
