Vaults employ strategies to automate the best yield farming opportunities available.
They were designed so that the community could work together to build new strategies to find the best yield.
Simply put vaults can do this:
Use any asset as liquidity.
Use liquidity as collateral and manage collateral at a safe level in order to avoid a default.
Borrow stablecoins.
Put the stablecoins to work on some farming.
Reinvest earned stablecoins.
Yes you could, but vaults help you save on gas, keep a good collateral/debt ratio to avoid defaults, and auto optimizes for the highest yielding stablecoin strategies, even while you are sleeping.
No. This is the historical average for that vault. Current APY / returns are not shown as vaults are a beta product and being tested live.
While the assets deposited can't decrease, the debt of the vault can increase. If a strategy does not manage to outperform the debt, then a portion of the asset will be impermanently locked. If a strategy later outperforms the debt again, the asset will again be available to withdraw. There are mechanisms in the vaults to prevent this but nothing is bulletproof.
Smart contract risk with any contracts that the vaults interact with.
yLINK and yaLINK
What's the difference between LINK and aLINK vaults?
None in terms of returns. Deposited LINK will be deposited into Aave generating aLINK (Aave interest bearing LINK). So depositing directly into aLINK vault you are one step ahead in the process.
Why is the yield different for aLINK and LINK vaults?
aLINK has a 0.5% insurance "fee" (this is returned when it is outperformed). LINK vault doesn't have this fee to avoid double dipping.
yETH and yWETH
What's the difference between WETH and ETH vaults?
None in terms of returns. Deposited ETH it will be wrapped into WETH anyway. The WETH vault just makes it easier for other Ethereum protocols to interact with this vault.
How does ETH vault protect itself from liquidation?
This vault reads ETH price directly from the Maker's OSM (Oracle Security Model), a system that reads Oracle price 1 hour in advance. This gives the vault 1 hour to pay the CDP debt before liquidation. Also, the vault keeps increasing collateralization by depositing profit on each harvest call.
Other Vaults
No. The vault will farm CRV then sell it on the market automatically. When you withdraw you will get more yCRV.
No, yCRV is not worth $1, and no it is NOT a stablecoin. You can think of yCRV as an index of yield bearing stablecoins (yDAI+yUSDC+yUSDT+yTUSD) that also generates yield (trading fees from the Curve Y pool) as well. Therefore the price of yCRV is non-decreasing.
You can’t get the same numbers for two completely different coins. The new sBTC is following the same strategy that the yCRV vault using curve liquidity pool. The obvious answer is that there aren’t many safe platforms accepting YFI as stake so there aren’t much valid strategies for the YFI vault right now.
You can only withdraw the crypto asset type that you put in.
You will get the amount you originally put in, plus the yield you've earned, minus the fees.

Notes:
Withdrawal Fee only applies on funds withdrawn from active Strategies.
Each vault has some amount of the total funds idle and most of them active in the Strategy.
When there is a withdrawal, if idle funds can cover the full amount, there will not be a withdrawal fee applied. If funds will need to be pulled from the Strategy in order to cover the withdrawal request, the Withdrawal Fee is applied.
Performance Fee is only applied on the performance gains.
For v1 vaults, the proceeds from this fee is split between Treasury and Strategist 90:10.
For v2 vaults, the split between Treasury and Strategist is 50:50.
Management Fee is annualized and assigned to Treasury. It accrues per block, is collected on each harvest and is applied on the total of the funds managed by the Strategy.
Yearn's vault strategies are modular smart contracts for each vault that tells it what assets to borrow, which assets to farm, and where it should sell the farmed assets.
In the future we plan to make a dashboard to make the strategies and APY easy to understand.
Developers write them but the multi-sig, instructed by YFI voters, decides if they will be implemented or not.
For now you can post your strategy on the forum in the strategy section. Detailing what it should buy/sell/farm and what the current APY is. There will be a template to help you get started.
Post it on the forum or get in touch with the developer team, if you get support for your idea and it ends up being implemented and approved, it will be used in the vaults and you can get paid for it.
Strategy creators watch the markets and write strategies that they think are safe while giving the highest yield. They change them according to current yields on the market.
Earn is a yield aggregator for lending platforms that rebalances for highest yield during contract interaction.
Zap allows users to convert supported tokens with just one contract interaction to reduce transaction costs.
Well, it does take a lot of gas and could be costly, even more so than doing it yourself manually, but if you have a big transaction and are in a rush it is a great method to get into a DeFi position or liquidity pool fast.
yInsure, also known as Cover, is a pooled coverage system providing insurance against smart contract risk.
It has no KYC requirement and is underwritten by Nexus Mutual.
Leveraged stable coin trades (testnet).
0 capital automated liquidations for Aave (testnet).
Single sided automated market maker (testing in mainnet).
Credit delegation vaults for smart contract to smart contract lending (testnet).
A lot of real-time discussion happens on the telegram and discord but for a proposal to turn into a YIP (Yearn Improvement Proposal) it needs to be posted and discussed on the forum.
This is the main place token holders check for governance related issues.
Including non-English channels.
The process is roughly:
forum discussion (minimum three days)
promote to YIP (usually done by mods), add YIP to github, put on Snapshot (minimum five days off-chain votation)
announce

Outgoing signers were:
They are in close contact with one another, but Andre's priorities are his own. They can be instructed via YIPs.
Yes! Meet some of the developers behind Yearn:
You can participate in YFI by voting on YIPs that are active, discussing the YIPs yet to be proposed off-chain on the forums and talking about YFI in the Telegram and Discord. If you know a second language help us translate the site and YIPs into that language.
Yes, you have to use the Metamask browser
If you're using MetaMask and you put your transaction through but it's going too slow, you have the option to speed it up by clicking the speed up button below your last pending transaction under "activity". This should resend the same TX again with a higher gas price to get it confirmed faster.
Aave is an open source and non-custodial protocol enabling the creation of money markets. Users can earn interest on deposits and borrow assets.

Andre explains and in these two blog posts.
Various third party sites provide APY and other info, they are listed below in .
As of now, only some Vaults have been .
v1 Money Market vaults, formerly called iEarn, can be found .
Additional vaults can be found .
When you withdraw your yCRV from the vault, you get back yCRV + plus interest accrued - fees, all in yCRV. Since it is the yCRV token you got back, it is already staked in Curve Y pool making stablecoin swap fees. No need to do anything else with Curve, unless you want to stake it to generate CRV.
Idle funds is the difference between vault holdings and strategy holdings, and can be seen on .
Further reading, see , , , and .
We plan to make a dashboard in the future that will clearly show your current APY of all the positions you have open. Currently for the Vaults as they are still in beta we are not showing the APY live, but it is post on around once a day. You can roughly estimate the yield you are getting by looking at what the is farming and checking what its APY is.
For example if yCRV vault is farming the CRV token, you can check what the yield is on for the Y pool
You can view the current strategies implemented at .
Deposit DAI, USDC, USDT, TUSD, or sUSD and it will auto lend to the highest lending rate on these platforms , or (Ddex and Fulcrum are currently disabled).

Zaps were made by DefiZap which is now as a type of all in one DeFi routing service.
"Zaps allow you get into a DeFi position in one transaction — it’s called zapping in." - .
Note that this is an old article and was formed as a result of DeFiSnap + DeFiZap coming together to create the ultimate hub for Decentralized Finance aka #DeFi. So some of the stuff in the article above is out of date, but you can still use Zaps on Zapper.fi.
With a zap you can take your DAI, for example, and get yCRV with it in one transaction. Normally, to turn DAI into yCRV, you would have to go to earn, deposit DAI and receive yDAI, then go to and deposit your yDAI and then you would get yCRV. This is a lot to do, so instead you can do it in one transaction!

A YIP or Yearn Improvement Proposal is how features are added to the Yearn ecosystem. Users start a proposal on the forum, discuss it and gauge the sentiment of if the proposal will be accepted. If a lot of users agree with it then it can be posted on for everyone to vote on without spending gas.
According to a proposal should be discussed in the forum for at least three days. If after three days there is a 25% “For” vote in the forum poll it will then move to formal voting via Snapshot.
As established in there isn't any quorum requirement for a YIP to be approved, but the votation on must be open for at least five days and have a majority support (> 50%) in order to pass.
The default template for proposals can be found on + on the if you make a post under proposals or discussion it will auto-fill in the template as well.
Anyone can post a proposal on the forum for discussion within the community. If it's promoted to off-chain votation (via ), only someone holding 1 YFI can submit it to Snapshot. In case your proposal made it to off-chain votation and you don't have enough YFI, mods will help you.
Stake your YFI in the governance or deposit it in the to be able to vote off-chain (gasless) for YIPs on .
No, you'll only vote with the YFI that you have in the governance and in the prior to the snapshot taken at the start of each off-chain votation.
You can view them on or at .
You should stake only if you want to vote on YIPs. After there isn't any rewards distributed to governance stakers. Instead, all the fees collected by the protocol are used to buy back YFI on the open market. These YFI is used to reward contributors and other Yearn initiatives.
Yes. You have to stake your YFI at in the v2 tab under Governance V2 or in the to have your votes counted. Since Yearn uses for off-chain votations, for each YIP voted off-chain there'll be a snapshot at a given block of all the YFI tokens staked in governance and in the vault. Only people with YFI staked in governance or in the vault at the time of the snapshot will be able to vote in that YIP.
A poll just gauges the sentiment of what the community is feeling on the proposal while an off-chain vote (via ) will be binding and will take effect if it passes.

Andre can build out the Yearn ecosystem and come up with new products. Usually, he posts his thoughts and ideas on the or on his for everyone to see.
Yes. Yearn has a core team that receives recurring payments. Grants are also distributed to valuable contributors in a monthly basis. For instance, see the .
If you want to contribute to the project as well just reach out to our community managers on //. We'll also release soon a Contributor's Guide.
Yes, we do! We need all kinds of people to help make the Yearn ecosystem a thriving product and to give value to YFI. You can ask in the Discord or Telegram about applying or post on the forum. State how you think you can add value to Yearn, and how much you think you should be paid from the community pool. Also, you can go to the as well for funding on your work for the Yearn ecosystem.

You should always make sure to set your gas properly if you want a transaction to go through quickly. Check current gas prices at or .
If you've tried everything and your transaction is still stuck pending, you can fix it by sending a transaction to the nonce of the first stuck transaction with a high gas price to overwrite the stuck queue. Here's a good explaining how to do this.
If you're seeing higher than normal fees while using the Yearn ecosystem then it may be due to Ethereum congestion and abnormally high gas costs. Check . Your options are to wait until gas prices drop or spend the money to process your transaction now.
If the gas prices are crazy high, that means there is an error and the transaction will not be able to process. For instance if you are trying to deposit a token you don't have or if there is no cover available for a contract at .
Curve is an exchange liquidity pool on Ethereum (like ) designed for (1) extremely efficient stablecoin trading (2) low risk, supplemental fee income for liquidity providers, without an opportunity cost. Curve allows users (and smart contracts like 1inch, Paraswap, Totle and Dex.ag) to trade between DAI and USDC with a bespoke low slippage, low fee algorithm designed specifically for stablecoins and earn fees. Behind the scenes, the liquidity pool is also supplied to the Compound protocol or yearn.finance where it generates even more income for liquidity providers.
