Yearn Merges with C.R.E.A.M.

We are pleased to announce that the C.R.E.A.M. lending platform has officially joined the Yearn ecosystem. Yearn and C.R.E.A.M. developers will join forces to launch C.R.E.A.M. v2. This upcoming launch will expand C.R.E.A.M.'s lending infrastructure and introduce new leverage tools that will be utilized by other Yearn products. A few notable synergies that will be formed include

  • C.R.E.A.M. will serve as the launchpad for our upcoming StableCredit product.

  • Yearn yVault shares will be used as collateral in C.R.E.A.M.

  • yVaults will be able to access leverage using funds within the C.R.E.A.M. lending platform.

  • C.R.E.A.M. & Yearn development resources will merge.

  • Yearn & C.R.E.A.M. TVL will increase.

  • A new collateral protocol credit solution will be launched.

  • Yearn and C.R.E.A.M. can offer pair lending.

This is an exciting new development for us as we have been evaluating how to incorporate a lending platform natively into our ecosystem, and also find a suitable partner to help us launch StableCredit. 

StableCredit is an upcoming product that will combine three pillars of existing DeFi infrastructure: (1) synthetic debt, (2) money markets, and (3) Automated Market Maker (AMM) technology. We wrote an in-depth description about StableCredit in a prior newsletter, which you can read here. You can also read the original Medium post introducing it, or our official documentation

The Medium post describing the C.R.E.A.M. merger can be found here

Yearn & Pickle Form Symbiotic Relationship

The Yearn community is pleased to welcome developers from Pickle Finance to the Yearn ecosystem. Pickle developers will serve as Strategists in our upcoming Yearn 2.0 yVault release. Yearn 2.0 yVaults will incorporate a 2% management fee, and a 20% performance fee. The performance fee will be split between Strategists and Yearn governance. You can read more information about this upcoming fee structure change here

This new relationship will reduce duplicate work, increase specialization, and leverage shared expertise. A brief list of the changes are as follows: 

  • Pickle pJars will now be vaults in our upcoming 2.0 yVault release.

  • Pickle tokens will now be rewarded by staking yVault tokens into newly introduced gauges.Pickle tokens can be placed in time-locked escrow to receive DILL, a new governance token for Pickle finance. DILL will also boost rewards received from Yearn yVaults.

  • A new token, CORNICHON, is introduced and will be proportionally distributed to users affected by the recent Evil Jar attack against Pickle’s DAI pJar. 

Ultimately, end users of Yearn yVaults will benefit from higher rewards due to receiving PICKLE rewards, while the Pickle ecosystem will benefit from Yearn’s expertise in development and security. Pickle developers will earn additional fees as Strategists under our upcoming yVault 2.0 release.

Yearn & Cover Merger

Yearn and Cover will join forces and Cover will now serve as the backstop coverage provider for Yearn products—while continuing to serve the broader DeFi market. Cover is in the process of creating a perpetual coverage system that will enable continuous protection against adverse events, without expiration. All current coverage products within DeFi have a fixed expiration date. As a result, Yearn yVaults will be natively covered under these perpetual coverage products.

PowerPool Integrates YFI 

PowerPool enables token holders to lend, pool, borrow, and gain income from governance tokens. It also oversees the PowerIndex, which is a decentralized ETF consisting of eight governance tokens. CVP token holders govern the PowerIndex. This allows CVP holders to vote on Yearn Finance governance proposals using YFI held in its meta-governance contract. PowerIndex is the first index of its kind, and we are excited to join the PowerPool community to enable this functionality.

The Yearn Ecosystem Ethos

There have been several mergers and/or partnerships formed within the Yearn ecosystem this past week. We want to remind readers that at its core the Yearn ecosystem fosters and encourages a collaborative development environment. Yearn is a yield-aggregator and relies on composability of many different protocols within DeFi on the Ethereum blockchain. This translates to a developer community that encourages collaboration between other developers and protocols in order to create new, innovative technology. 

We invite more developers to collaborate with the Yearn ecosystem, or reach out to us if you have ideas where new synergies can be formed. 

3rd Monthly AMA Recap

On November 27th, we conducted our 3rd Ask Me Anything (AMA), and we were joined by special guest Tascha Panpan from Alpha Homora who discussed their YFI/ETH leveraged liquidity pool product. We conduct monthly AMAs so that community members are able to ask questions about anything related to the Yearn ecosystem. We will announce the date for our next AMA in the future. Stay tuned!

Launch of yGift

We are pleased to announce the launch of yGift, a platform for giving gifts, grants, and gratitude. Upload an image or GIF, and add a message to send an ERC-721 non-fungible token (NFT) to a friend. You can also send one of several tokens as a part of the gift (YFI, yUSD, y3Crv, DAI, USDC, WETH, or WBTC).
