Supply and Earning in Blend

How do I supply?

Browse to the "Supply" section and click on "Supply" for the asset you want to supply. Select the amount you'd like to supply and submit your transaction. Once the transaction is confirmed, your supply is successfully registered and you begin earning interest. The first supply of one asset will require an additional approval transaction.

How much will I earn?

bTokens holders receive continuous earnings that evolve with market conditions based on:

• The interest rate payment on loans - suppliers share the interests paid by borrowers corresponding to the average borrow rate times the utilisation rate. The higher the utilisation of a reserve the higher the yield for suppliers.

Each asset has its own market of supply and demand with its own APY (Annual Percentage Yield) which evolves with time. You can find the average annual rate over the past 30 days to evaluate the rate evolution, and you can also find more data on the reserve overview of each asset in the home section on the app.

Is there a minimum or maximum amount to supply?

There is no mininum supply amount. Still, it's important to take into account that for really low amounts it is possible that the transaction cost of the process is higher than the expected earnings. It is recommended that you consider this when supplying very low amounts.

Blend introduces the supply cap parameter, controlled by Blend Governance. If a reserve has a supply cap, this limits the total amount of the asset that can be supplied.

Can I borrow using stable and variable rate at the same time for one asset?

No, you can only borrow using stable or variable rate, if you switch to your desired rate it will switch the rate for your whole debt on that asset. Despite this, you can have different borrow rates for different assets.

How do I withdraw?

To withdraw you need to go to the "Dashboard" section and click on “Withdraw”. Select the amount to withdraw and submit the transaction. Also, you can use your “bTokens" as liquidity without withdrawing.

You would need to make sure there is enough liquidity (not borrowed) in order to withdraw, if this is not the case you would need to wait for more liquidity from suppliers or borrowers repaying.

Can I opt-out my asset from being used as a collateral?

Yes. After supplying your assets, you are able to unselect the asset so that it will not be used as collateral. The opt-out is available in the "Supply" section within your dashboard. Simply switch the "use as collateral" button on the asset you would prefer to opt-out from being used as a collateral. You can withdraw your assets without opting out of using them as collateral, as long as those funds are not actively being used to borrow and the withdrawal would cause a liquidation on your loans.
