What is a Vault?

Vaults are investment instruments that employ a specific set of strategies for yield farming. They make use of automation to continually invest and reinvest deposited funds, which help to achieve high levels of compounded interest. By using a Beefy vault to compound your gains, you save thousands of transactions with their associated gas costs, and precious personal time. Instead of manually harvesting and selling rewards, buying more tokens, and reinvesting that continuously, a vault does all that automatically at a high frequency.
Vaults are the core of the Beefy.Finance ecosystem. In a Beefy vault, you earn more of the asset you stake in it, regardless if this is an liquidity pool (LP) token or a single asset. For example, vaults where one can stake BTC-BNB LP will result in more BTC-BNB LP over time, effectively growing your share in the vault and thus allowing for more and more rewards over time.
Despite the name 'Vault' suggests, user funds are never locked in any vault on Beefy.Finance. One could always withdraw from a vault at any moment in time. Beefy.Finance also does not own user funds staked in vaults. However, it is generally best to view vaults as investment tools to store funds for the medium to long term in order to have the effects of compounding really kick in.
When browsing the vaults on the platform, you will see the annual percentage yield (APY), which takes the frequent compounding into consideration compared to annual percentage rate (APR) which does not. You will also see daily interest percentages and the total amount invested in a vault by all users (TVL). Furthermore, one can see what underlying platform the vault is using as a source of revenue.
Each vault can either refer to a pair of tokens invested in liquidity pools, such as CAKE-BNB LP tokens within the Binance Smart Chain ecosystem, or a single token invested in lending platforms or single stake reward pools. After depositing tokens to a vault, the user is supplied with vault specific mooTokens which represent their share in the vault. We will elaborate on mooTokens in the next section.
Anyone in the Cowmoonity can work together to build new strategies and submit them to governance for voting. We look at vault requests via our official forum where anyone is free to submit vault requests.
Summarizing, vaults can:
  • Efficiently execute yield farming strategies.
  • Compound rewards into the initially deposited token amount.
  • Use any asset as liquidity.
  • Provide one asset as collateral for another.
  • Manage collateral at a safe level to mitigate liquidation.
  • Put any asset to work to generate a yield.
  • Reinvest earned profits.
Users can sit back and relax, and watch their investment grow!

What are mooTokens?

A mooToken acts as a receipt for your deposit into any Beefy vault. For example, you receive mooBIFI tokens when depositing BIFI into the BIFI Maxi vault. The amount of mooTokens you receive will not 1:1 match the token amount initially deposited, but it does represent your proportional share of the vault. As a vault generates profit, the amount of mooTokens in your wallet remains constant while the underlying invested token amount in the vault increases.
Beefy's mooToken system has a few major advantages. Firstly, mooTokens allow any user to withdraw their fair share of deposited funds. Secondly, the system allows you to deposit the mooToken receipt to a cold or hardware wallet for ultimate safety. Thirdly, your privacy is maintained, as you remain anonymous to Beefy. Your funds in the vault are not tied to the wallet address from which you made the deposit, since the mooTokens are the only evidence of your share in the vault. Therefore, you could withdraw your share of funds from a different address if you moved your mooTokens to it.
Whenever you want to withdraw the tokens that are staked for you in the vault, you need your mooToken receipt to withdraw the initially deposited tokens plus extra vault yield. Beefy.Finance users should hold on tightly to the mooTokens (deposit receipt) and not sell or exchange it to strangers, since you would lose ownership of your staked assets in the vault if you did so!

How often do the vaults harvest their profits and reinvest?

Vaults are normally harvested multiple times daily and profits are automatically reinvested (compounded). You can check the harvesting and compounding rate of a vault using this how-to guide.

Why can't someone just do this themselves?

They could, but vaults help you save on personal time and transaction fees, maintain healthy collateral to debt ratios, self-optimize for the best possible yields, and automatically reinvest earnings. Attempting to do this manually would result in large inefficiencies. At Beefy we like to say: "Sit back and relax, the vault does all the work for you."

What is the vault fee structure?

Most vaults have a performance fee structure, taking 4.5% of harvest rewards. This 4.5% on profits is again split up: 3% is distributed back to the reward pool and to $BIFI stakers, 0.5% is allocated to treasury, 0.5% is for the strategist that developed the vault and 0.5% for the one calling the harvest function. These fees are already built into the APY of each vault and daily rate. You do not need to calculate these yourself.
The performance fee on additional yield i.e. vault profits is largely distributed back to $BIFI stakers and is the main source of Beefy.Finance's platform revenue. A part of it also funds the treasury which is used to further fund platform development and security and other initiatives. The performance fee was also implemented to promote community engagement and governance participation. A successful and engaged community is critical for our future growth, which in-turn rewards platform users even more.
Furthermore, vaults have a withdrawal fee. The main purpose of this fee is to prevent possible exploits from bad-faith actors. Without the fee, somebody could deposit just before the harvest() function execution and withdraw straight after that event, taking a % of the gains generated by legitimate stakers. Withdrawal fees stay in the vault and are shared amongst vault funds.

Special vaults

The Pure CAKE vault, released 14 June 2021, has 0% deposit fee, 0% withdrawal fee, 0% call fee, 0% treasury fee and 0% strategist fee. There is only a performance fee, that goes directly to BIFI Maxi stakers, of 1%. To eliminate bad actors from stealing harvest rewards, the Pure CAKE vault harvests directly before a user deposits their CAKE.

Does the performance fee get taken out when I withdraw my funds?

  • No, the performance fees are on profits and are taken every time someone calls the harvest() function.

Does the vault page show the APY?

Yes. Our displayed APY values reflect the predicted rate earned on a vault in a year. This rate is determined by the underlying platform it uses, the strategy that it is interacting with at the time, the total amount of funds in the vault and also takes into account the effect of compounding. As a unique feature, we have also included all vault fees in the APY calculation. What you see is what you get!

What risks do the vaults have?

Beefy vaults are audited, but this does not mean that a vault is entirely risk free. Below are some of the general vault risks:
  • Assets deposited into the vault have no risk of decreasing in quantity but can decrease in monetary value.
  • As with any smart contract, the ultimate risk is that an investor's funds can end up stolen or unable to be withdrawn. The team does take steps to quantify the security risks of smart contracts and only will interact with ones that meet a specific set of requirements after excessive testing to make sure the underlying platform does not contain so called 'rug-pull' functions.
More detailed vault risks, or better yet, information on Beefy's vault safety expressed by the Beefy Safety Score can be found here: Beefy Safety Score.

What are the different vaults?

  • Money Market : Utilizes lending platforms, such as Venus on BSC, to generate the highest possible yield for these coins (e.g. BUSD, BNB, LINK, DOT, DAI, USDT, ETH, or BTCB).
  • Native Token Farming : Takes advantage of the high yield on popular farms by depositing another asset to earn, sell and compound profits of the native reward token.

What will I get out when I make a vault withdrawal?

You will always withdraw the token type that you deposited, because at Beefy you earn what you stake. You will get the amount you deposited plus the yield generated minus the vault withdrawal fees.

How do LP vaults work?

Liquidity pool (LP) vaults work by reinvesting the fees awarded to LP participants. In return for providing liquidity to the pool, many platforms reward investors with tokens. Our vaults regularly harvest these rewards, sell it, buy more of the LP’s underlying assets, and then reinvest to complete the cycle.
This compounds the rewards gained from a liquidity pool. Beefy.Finance creates strategies that automate this process, saving you time and gas fees in comparison to farming manually. This is all done for a tiny fee that is distributed back to those who stake in Beefy's governance pool or in the BIFI Maxi vault. A small percentage also goes to the Beefy Finance treasury.

How often are balances updated in the vaults?

  • Pending rewards are not reflected in the balance until they are swapped for the initial deposited token. This can vary depending on the strategy running.

Why do I have less mooToken than the amount of tokens I deposited?

  • The mooTokens represent the share of the Vault the user has. As the vaults generate profit, the amount of shares (mooToken) remain constant, and the underlying token amount increases.
  • There generally are no deposit fees, so the amount of tokens you deposit is maintained the second after you deposited. That amount should increase over time as the strategy generates profit.

How do vaults get added to Beefy.Finance?

New potential vaults can be discussed in our Discord in the #whiteboard channel. Our strategists then add the potential investment strategy to our strategy list. A priority is assigned to each new, potential strategy based on its APY, TVL and sustainability. Our developers/strategists then attack the list from top priority to bottom. The official forum is used for submitting actual vault requests.

What’s your vault naming process?

Each vault on the platform is named after the token that users can deposit in it. For example, the CAKE-BNB LP vault uses CAKE-BNB LP tokens for its investment strategy. A BTC vault uses the BTC token, etc.
Underneath the vault name, you can find the platform used for investing the token and farming its yields. For example, Uses: Venus means that that particular vault invests the token in Venus, a DeFi algorithmic money market and synthetic stablecoin protocol.

How do lending vaults work?

The following applies to: Aave, Banker Joe, Belt, Blizz, Geist, Scream, Venus, and similar lending platforms.
Most Beefy single asset vaults utilise decentralized marketplaces for lenders and borrowers. By depositing your initial asset in the vault, Beefy deposits it into the lending marketplace and borrows against your token at safe levels of collateral.
The borrowed tokens are redeposited into the platform, and once again used as collateral to borrow more tokens. This cycle is repeated multiple times to generate as much interest as possible, which is used to buy more of your originally deposited assets. This strategy is also known as a folding strategy. It is noteworthy that this "leveraged" multi lending and multi borrowing is only with the deposited vault token, so there is no liquidation risk due to token price swings.
Because of the multi supply and borrow cycle, a transaction fee for these vaults is generally higher as compared to other vaults. Also, when available liquidity on the lending platform is low, it can potentially lead to temporarily unavailable funds. This event will naturally resolve itself when liquidity returns.
Due to accruing debt/supply interest, one may notice that the deposited token amount may decline ever so slightly in between harvests. After the harvest, you will see your deposited token amount increase as the yields are compounded back into it. The change in deposited token amount over time of a typical lending style vault looks as follows:
After a harvest event, the yields are added to the deposited token amount
