A loan top-up is an increase to the amount of collateral in your loan. This lowers the LTV level and reduces the likelihood of loan closure due to a drop in value of the digital asset collateral. You can top-up your loan by signing into your account, opening the B2X or Dollar Loans tab and clicking on the button that says “Top-Up”.
The system will show you two options: 1) From Transaction account and 2) From external source.
If you choose the Transaction account option, you will only need to input the amount you want to send from your Transaction account to your loan. This process is instant, but you need to request it manually.
On the other hand, if you select from an external source, you will be shown the collateral address where you need to send the additional collateral for the top-up, as well as the QR code. Bear in mind that transactions are only taken into account towards the LTV when they have one or more confirmations on the applicable blockchain network, so they may not arrive in time when the network is very congested and there is a sharp price drop of the digital asset collateral.
