Why would I borrow instead of selling my assets?

Selling your assets means closing your position on that particular asset. Hence, if you are long on the asset, you would not be entitled to the potential upside value gain. By borrowing you are able to obtain liquidity (working capital) without selling your assets. Users are mainly borrowing for unexpected expenses, leveraging their holdings or for new investment opportunities.

How do I borrow?

Before borrowing you need to supply any asset to be used as collateral. After this, simply head to the Borrow section and click on “Borrow” for the asset you want to borrow. Set the amount you need based on your available supplies that would be used as a collateral for the loan. Select either stable or variable rate and confirm your transaction. You can always change your rate afterwards as many times as you want.

How much I can borrow?

The maximum amount you can borrow depends on the value you have supplied and the available liquidity. For example, you can’t borrow an asset if there is not enough liquidity or if your health factor doesn’t allow you to.

What asset do I need to repay?

You repay your loan in the same asset you borrowed. For example, if you borrow 1 ETH you will pay back 1 ETH + interest accrued. If you want to pay back the loan based on USD price you can borrow any of the available stablecoins as DAI, sDAI, USDC and USDT.

What is the difference between predictable and variable rate?

Predictable rates act as a fixed rate in the short-term, but will change based on a MakerDAO governance decision. The variable rate is the rate based on the offer and demand in SparkLend, and will constantly change.

How much will I pay in interest?

The interest rate you pay for borrowing assets depends on the borrowing rate which is derived from the supply and demand ratio of the asset in the case of the variable rate; for predictable rate assets (DAI), the borrowing rate is defined by MakerDAO governance. The interest rate of a variable rate changes constantly. You can find your current borrowing rate at any time in the Borrowings section of your dashboard.

What is the health factor?

The health factor is the numeric representation of the safety of your deposited assets against the borrowed assets and its underlying value. The higher the value is, the safer the state of your funds are against a liquidation scenario. If the health factor reaches 1, the liquidation of your deposits will be triggered. A Health Factor below 1 can get liquidated. For a HF=2, the collateral value vs borrow can reduce by 1 out of 2: 50%. The health factor depends on the liquidation threshold of your collateral against the value of your borrowed funds.

What happens when my health factor is reduced?

Depending on the value fluctuation of your supplies, the health factor will increase or decrease. If your health factor increases, it will improve your borrow position by making the liquidation threshold more unlikely to be reached. In the case that the value of your collateralised assets against the borrowed assets decreases instead, the health factor is also reduced, causing the risk of liquidation to increase.

When do I need to pay back the loan?

There is no fixed time period to pay back the loan. As long as your position is safe, you can borrow for an undefined period. However, as time passes, the accrued interest will grow making your health factor decrease, which might result in your deposited assets becoming more likely to be liquidated.

How do I payback the loan?

In order to payback the loan you simply go to the Borrowings section of your dashboard and click on the repay button for the asset you borrowed and want to repay. Select the amount to pay back and confirm the transaction.

How do I avoid liquidation?

In order to avoid the reduction of your health factor leading to liquidation, you can repay the loan or deposit more assets in order to increase your health factor. Out of these two available options, repaying the loan would increase your health factor more.

How can I use permit?

The permit function of SparkLend allows you to move your funds from a wallet by simply signing an approval message instead of approving a transaction on the network to avoid gas fees.
