When you borrow through Flexline, repayment is required at the end of the loan duration, although the loan can be terminated at any time. Early termination includes the original principal plus half of the remaining interest pending for the loan.
Remember, if you hold a loan to maturity, it will automatically be repaid from funds in your main wallet on the end date - no action is necessary on your part. However there may be a fee associated with converting assets into the loan currency if there is insufficient quantity.
