What is Burrow?

Burrow is a decentralized, non-custodial, autonomous money market similar in nature to Aave and Compound.

Burrow aims to unlock liquidity for interest-bearing assets, particularly layer 1 staking derivatives such as stNEAR and stETH. Users of Burrow will be able to deposit stNEAR as collateral, then borrow more NEAR to create a leveraged staking position, or borrow a stablecoin to make a self-repaying position.

If you don’t have a NEAR account, just follow this guide to set up your NEAR wallet first!

Launch the Burrow app and connect your NEAR wallet at the top right corner.

How to Supply

Users can supply assets to the protocol and begin earning interest.

The interest rates are variable and will fluctuate based on the utilization rate for the given asset. (More info on the interest rate model here.)

Supported assets at launch:

  • NEAR
  • stNEAR (staked NEAR)
  • ETH
  • wBTC
  • USDT
  • USDC
  • DAI
  • BRRR (Burrow’s native token)

Browse to the “Deposit” section and click on the asset you want to deposit.

(1) Enable “Use as collateral.”
This means that you will now be able to borrow assets against the amount you deposited into the supply pool.

This also means that your funds can potentially be liquidated. See “Health Factor” and “Liquidation” sections below for more info.

(2) Simply supply assets, don’t “use as collateral.”
This means that you will simply earn interest on the amount you supplied to the pool, without further borrowing any assets. In this case, your assets are not subject to liquidation.

You can always turn on “use as collateral” later in your “Portfolio” page.

Your deposit is now successfully registered, and you can begin earning interest. The “APY” (annual percentage yield) number tells you how much you can expect in $BRRR rewards for supplying assets.

Now that you have supplied your assets to Burrow’s liquidity pool, you can also borrow funds against it.

In order to borrow assets, you must first enable “Use as Collateral.” If you haven’t turned on the “Use as collateral” button while depositing, you can adjust your position in the “Portfolio” → “Adjust Collateral” section.

On Burrow, you can pick and choose which deposited assets you want to use as collateral, as well as customize the rate of colleteralization.

The risk of a position can be understood through the Health Factor, which represents the combined collateral ratios of the borrowed assets.

  • If the health factor is higher than 100%, it means the account is in a good state and can’t be liquidated.
  • If the health factor is less than 100%, it means the account can be partially liquidated and can’t borrow more without repaying some amount of the existing assets or providing more collateral assets.

To learn more about how the health factor is calculated, see here.

Liquidation is when your position is forcefully closed by the protocol (i.e. your collateral is sold off) because, due to changes in market conditions, the value of your collateral is no longer enough to secure your debt based on the Health Factor, meaning that you are at risk of not being able to pay off your debt. This kind of insolvency threatens the protocol, and therefore a liquidation event is triggered through bots to prevent it in advance.

This might happen when:

  • The collateral decreases in value (e.g. wNEAR price decreases from 20$ to 10$)
  • The borrowed debt increases in value

You can read more about liquidation here.

When your Health Factor is…

  • Green: Your funds are (generally) safu
  • Yellow: Risk is moderate
  • Red: Your funds are at a high risk of being liquidated
  • We recommend users DO NOT set the collateral utilization rate at 100%. You are asking to be liquidated!
  • The Health Factor can change if the price of the underlying assets change to a great degree. We recommend users monitor their Health Factor from time to time, especially if there are rapid changes in market conditions.

How to Manage Your Assets

Access “Portfolio” in the menu to view and manage your Deposited and Borrowed assets.

Your “Net APY” is your total APY (annual percentage yield) which calculates how much you are earning from depositing assets (deposit APY) minus how much you owe the protocol from borrowing (borrow APY).

Choose the asset you want to withdraw and click “Withdraw.”

If you want to withdraw all your assets, make sure to repay your debt first. If withdrawing at 100% doesn’t work, lower to 99% or so and try again.

If you are withdrawing only a portion of your assets and maintaining your debt position, beware of how this will change the Health Factor and manage your liquidation risk.

On Burrow, you can customize the rate at which your assets are collateralized, and set it differently for each asset you supply. This is different from previous lending protocols whose collateral rates were set at a default rate.

You can set the desired collateralization rate when you first deposit your assets, or go to “Portfolio” and click “Adjust Collateral.”

To pay off your outstanding debt, go to the “Portfolio” section and click the “Repay” button.

Due to the difference in token standards, Burrow (and most other DeFi dapps on NEAR) use wNEAR (“wrapped” NEAR), not NEAR.

When you deposit, your NEAR will be automatically wrapped, so there is nothing you need to do. However, if you borrowed $wNEAR and are looking to repay, you have to do it as wNEAR. Use the Ref Finance Wrapping Page to wrap your NEAR into wNEAR first.

In the future, Burrow will support direct wrap/unwrap on the app itself. Furthermore, the wrap/unwrap function will be integrated to the NEAR wallet so that this issue is more easily resolved.

Burrow is Live on Mainnet! Read this FAQ to Get Started

The wait is over! The first money market on NEAR native is finally live on mainnet. This means more liquidity and DeFi…

Coming Soon: xBRRR Staking!

Shortly, staking will go live on Burrow. Users can stake their BRRR and receive xBRRR, with which they can access boosted rewards and participate in protocol governance. Stay tuned!
