In the event that there's no remaining balance on your BTC or ETH Transaction account to top up your loan's collateral, you will receive a notification email informing you that, due to lack of available funds, we were unable to Auto Top-up your loan(s).
You will have to take action by either sending funds to the loan's collateral address from an external wallet or depositing more funds into your BTC or ETH Transaction account and manually Topping-up your loan's collateral to avoid the risk of automatic liquidation.
