                  An amount of collateral equal to the Initial Margin Amount + 
                  the total value of your loan, will be escrowed. Please ensure you 
                  have enough collateral token balance and that you know what you are 
                  doing. After filling the order, the loan token will immediately be 
                  withdrawn to your wallet. If you don't return the full amount of loan
                  token before the loan term ends or the loan gets liquidated, you will 
                  lose a large portion of the collateral in order to compensate the lender 
                  for the full value of the loan.
