DeFi Giant Yearn leads the charge on ERC-4626 Token Standards Adoption

Yearn Finance, a vault-based and decentralized yield aggregation system, is the first major protocol publicly to support ERC-4626, providing legitimacy for others to explore the use of ERC-4622.

Yearn’s endorsement on Twitter is a “big deal,” according to ERC-4626 co-author and Ape Framework builder, Señor Doggo because it signals to other larger more established teams that ERC-4626 is worth looking into.

ERC-4626, a new standard for Ethereum tokens, is designed to streamline the design of different types of tokens that print money (aka yield-bearing tokens).

The novel standard was finalized last month and has already garnered use from some of decentralized finance’s (DeFi) largest players – perhaps an indication of the speed and innovation happening within the Ethereum ecosystem as the network gears up for its proof-of-stake upgrade called “the Merge.”

Before the introduction of ERC-4626, “the tokenized vault standard,” DeFi developers commonly wrote unique coding solutions to integrate yield-bearing tokens and spent their own money or the project to audit that custom-made code for potential security vulnerabilities.

According to Fei Protocol founder and co-author of ERC-4626, Joey Santoro, this was a massive headache for developers. The lack of standardization in yield-bearing tokens was a problem. inefficiencies and insecurities to propagate across DeFi.

DeFi is a subsector that is growing with $120.59 billion in total locked value on the Ethereum blockchain, people can have financial services and yield generation access without the need to use a traditional intermediary.

Yield-bearing tokens, like Aave’s a token, Compound’s cToken or Sushi’s xToken, are essential elements in DeFi because they represent a person’s share of yield-generating activity on a DeFi protocol.

It’s now.

ERC-46226 is standardization of yield-bearing tokens, making them simpler to create. Additionally, it provides an interface for tokens stored in vaults or smart contracts that draw liquidity on deposits of asset tokens. This allows for the creation and maintenance of yield farming strategies.

Santoro clarified, “The novel standard basically applies to any place where the user puts in a token and receives a token out.”

Moreover, developers don’t have to write new code to create custom vaults for every single new DeFi application.

Any application built on top of an ERC-4626 vault will work for any ERC-4626 token – much like building for ERC-20 tokens, the standard that launched the infamous initial coin offering boom in 2017.

DeFi developers believe that this will open the door to financial innovation in the sector with its improved composability.

Yearn leads

Yearn is one of the largest DeFi stakeholders said on Twitter Tuesday, “the Great Vault Standardization begins now” as “ERC-4626 will be the gold standard for any sort of interest-bearing token.”

According to Santoro, Yearn’s announcement on Twitter was its way of “putting their flag in the ground and saying we’re going to drive adoption of this standard.”

He predicts ERC-4626 will become ubiquitous in part because Yearn will drive adoption even if protocols don’t adopt ERC-4626.

Let’s say other major DeFi applications like Aave and Compound decide not to build on ERC-4626; Yearn can still generate a wrapper contract in which a developer can create another token that would wrap Aave and Compound’s yield-bearing token, making it compatible with the standard.

Yearn can thus force adoption in a way that is backward-compatible by creating wrapper vaults.

Or as Yearn said, “Yearn V3 + ERC-4626 = INEVITABLE.”

In use

Santoro said that it is a good idea for future developers to build directly according to the standard since wrapping requires extra gas or steps.

ERC-46226 is an important tool for DeFi developers. It allows them to contribute to different lending markets, yield aggregators, and intrinsically-interest-bearing tokens.

Santoro stated that developers from all parts of the DeFi ecosystem are using ERC-4626 to build on their projects. The standard, first proposed in January and finalized in March it is now being implemented by the likes of Alchemix, Balancer, Rari Capital, Fei Protocol and Open Zeppelin.

While there have been reports indicating that ERC-4626 is set to be implemented at the next Ethereum fork upgrade, these reports are a misconception, according to Santoro and Señor Doggo. It is final and being used by people already.

The developers can implement the new standard at their own pace since ERC-4626 doesn’t require a hard fork.
