Yearn Finance DeFi Partnerships: What Happened After 2020?

Status checked 13 August 2026: This article documents Yearn’s unusually rapid run of 2020 collaborations; it should not be read as a map of current integrations or as proof that every named protocol remains endorsed, active or covered by Yearn. The relationships had different structures—some were code collaboration or strategy coordination, not legal mergers—and several products described below later changed or disappeared.

Yearn itself remains active. Its 2025 recap says it expanded V3 vault infrastructure, launched curated Morpho vaults across several chains and incubated new products, while also learning from failures in composable partner systems. Governance approved a 2025 restructuring around autonomous revenue-producing teams. A July 2026 yTranche proposal was still in discussion and its contracts were described as being audited, so it should not be presented as a launched product.

Original 2020 partnership overview (historical archive)

The decentralized finance (DeFi) space has grown to include platforms in various sectors such as spot trading, derivatives, and futures. Interestingly, some networks such as Yearn Finance support yield farmers and liquidity providers through an aggregation service.

Instead of offering spot trading, lending, or borrowing functionalities, it allows users to deposit funds, then it distributes it based on projected returns and the risks involved.

However, this isn’t enough to drive meaningful DeFi adoption. Therefore, Yearn followed the partnership route to expand its ecosystem and to improve interoperability between DeFi systems.

In this article, we look at the most impactful partnerships in the Yearn ecosystem:

Yearn + SushiSwap

On November 3, 2020, Yearn’s creator, Andre Cronje, took to Medium to announce the coming together of his platform and Sushiswap. The connection between the two platforms meets as Sushi improves its automated market-making (AMM) outlooks while Yearn digs deeper into aggregating formulas. These qualities brought a need for cooperation between them, leading to:

A combination of development resources.
A rise in the total value locked (TVL) on each platform.
Working together to develop and launch Deriswap, a platform bringing together spot trading, derivatives, and futures trading.
Introducing Keep3r Network, an on-chain price oracle on the second iteration of Sushswap.
Additionally, liquidity providers on Sushi provide collateral for the Sushi money market.

Partnership with Cream Protocol

The DeFi aggregator platform partnered with Cream, a lending network similar to Aave, in developing the system’s second version. With the partnership, the Yearn and Cream team created Cream V2, which introduced or enhanced leverage and lending features. Notably, the new platform enables yield farming using leverage.

Additionally, Cream V2 acts as a springboard to power stable credit and yet-to-be-built lending functionalities. Apart from merging resources allocated towards development and seeing a rise in individual TVL, the partnership saw shares in Yearn Vaults qualify to provide collateral in Cream.

One feature added to Cream’s new version includes rotating multi-signature keys in order to improve deployment, iteration, and testing. Unchanged features include those that touch on governance and native tokens.

Akropolis and Yearn

The partnership is rather a unique one. Why? It aims to bring out the best in each platform’s team. Therefore, each team continues with their previous journey but leans on the other if they need help.

Furthermore, Akropolis users can access Yearn and a host of other networks such as Cream and Pickle. In return, Yearn investors benefit from Akropolis’s investment strategies and a pool of institutional networks. The partnership between the two platforms brought with it improvements on Akropolis.

For instance, there was a development of new vaults, an institutional application, some strategies, and a rotation of multi-signature. In addition, Akropolis’s native token was upgraded to be able to track losses.

The PowerPool Partnership

PowerPool is a decentralized protocol accumulating governance strengths in systems built on the Ethereum blockchain. In short, it brings together governance tokens from a wide range of DeFi protocols, such as Compound and Balancer.

The partnership with Yearn Finance connected YFI, the governance token on Yearn, with PowerPool’s PowerIndex. PowerIndex provides a DeFi index inspired by distributed exchange-traded funds (ETFs). The index exudes meta-governance functionalities and contains eight tokens, including YFI.

Note that the meta-governance aspect rides on concentrating user tokens from different DeFi platforms into a single contract. Next, the tokens’ voting weight is delegated to a group consensus. Notably, the contract generates a token that its holders can use to decide the other tokens’ fate in the pool.

So, what does the partnership bring to Yearn?

Having a share of the index gives DeFi lovers a share in Yearn.
It increases participation in YFI governance issues.
PowerIndex supports swapping. Thus, anyone can exchange another platform’s token with YFI and vice versa.
In return, Yearn benefits from more liquidity. Additionally, pooling YFI helps stabilize its price.

The Cover Merger

Although Cronje formally announced the partnership on November 28, 2020, the two platforms have been collaborating since Cover’s launch. The marriage between the two opens doors to advanced features targeting optimization, among other aspects.

The partnership allows Curve to provide backstop coverage to products built on Yearn. Their coming together allows Cronje’s network to enjoy Cover’s range of coverage known for supporting multiple collaterals. Yearn can mitigate risks for users through vault coverage. That’s not all. Underwriting coverage on Yearn becomes more profitable.

Fortunately, the benefits aren’t one way. For Cover, it’s hoisted to expand its wings to unchartered money markets. Additionally, it’s empowered to seek a bigger share of perpetual coverage and other products in the market. However, components such as the native COVER currency remain intact.

Pickle and Yearn

This is another key partnership in the Yearn ecosystem. Its uniqueness emanates from the fact that it’s supposed to eradicate duplicate works among the two teams. Doing so lets each team and individuals within a team work on what they’re extremely good at.

As a result, Pickle will launch new features such as reward Gauges. Governing members on the Pickle ecosystem receive DILL tokens when they lock their tokens for governance-related purposes. DILL holders share Gauge performance, withdrawal, and deposit fees.

On the other hand, Yearn users, especially Vault depositors, are incentivized to interact with Gauges through Vault shares. The depositors also receive more rewards by setting aside Pickle tokens to receive DILL.

Others benefits originating from the partnership include:

A merger of the platforms’ TVL.
Pickle finds its way into the Yearn ecosystem.
Pickle enjoys Yearn’s security, among other features.
Pickle’s reward Gauges rake in incentives from Yearn depositors.
The two protocols’ teams work together on strategy creation and split profits from the strategies.
There’s an overall increase in rewards for users in both circles.

Conclusion

By expanding the Yearn ecosystem, Cronje and his team seek to build an inter-connected DeFi world. With everything connected to everything, DeFi adoption naturally sets in.

Apart from interconnection and adoption, the partnerships focus on, for example, reducing the duplication of roles within teams working on DeFi projects. This encourages the birth of new products and features to help drive growth in the space.

In the process, DeFi enthusiasts benefit from enhanced products and yields, which further encourage interaction with DeFi-focused systems.

Yearn ecosystem FAQ

Did Yearn legally merge with all the protocols in this article?

No. “Merger” was often informal DeFi language for coordination, shared development or strategy integration. The arrangements did not all create one legal entity or identical governance.

Is the 2020 Yearn partnership list still current?

No. It is a historical snapshot. Each integration, token and user interface must be checked independently before being treated as active in 2026.

Is Yearn Finance still active in 2026?

Yes. Yearn's own 2025 recap describes active V3 vault development, curated Morpho vaults and work across multiple chains and partner ecosystems.

What are Yearn V3 vaults?

They are ERC-4626-compatible vault systems that can allocate a deposited asset among compatible strategies under defined management roles.

What changed in Yearn governance in 2025?

YIP-88 reorganized most contributor teams around measurable revenue activities while retaining team autonomy and a separate DAO operations function.

What are Yearn-curated Morpho vaults?

They are lending vaults curated by Yearn across supported networks and risk tiers. They still carry smart-contract, market, oracle, liquidity and borrower risks.

Has Yearn launched yTranche?

The July 2026 governance post described yTranche as a proposal in discussion, with contracts under audit and deployment contemplated only after approval and review.

Does a Yearn partnership guarantee another protocol's safety?

No. Composable DeFi can transmit losses through strategies, collateral, oracles and integrations. A relationship or brand association is not insurance.

Does depositing in Yearn mean funds are custodial?

Yearn vaults are smart-contract systems rather than conventional custodian accounts, but non-custodial design does not eliminate contract, governance or strategy risk.

How should users verify a current Yearn integration?

Start from Yearn's official interface and documentation, verify chain and contract addresses, inspect the live strategy and risks, and do not rely on archived partner announcements.
