Yearn Finance (YFI) becomes the first protocol to adopt Ethereum’s ERC-4626

Key Takeaways:

  • ERC-4626 aims to provide widespread benefits across Ethereum’s network.
  • YFI plunged by 20% in the past seven days now trading at $20.
  • Yearn Finance TVL has dropped from $4 billion in February to $2.8 billion in April.

LAGOS ( — Yearn Finance, a DeFi protocol running on the Ethereum blockchain, has become the first major protocol to officially adopt the newest Ethereum Request for Comments (ERC) standards, ERC-4626.

The blockchain platform announced plans to integrate ERC-4626 through its official Twitter account. It described the new standardization as “composability at its finest,” adding that ERC-4626 will boost DeFi adoption and enable users to move assets across chains better.

“ERC-4626 will be the gold standard for any sort of interest-bearing token,” Yearn Finance said.

What is ERC-4626?

ERC-4626 is a standard for tokenized vaults with a single underlying ERC-20 token. Notably, vaulting is the process of locking in a token on one chain so it can be minted into a token that you can use on a different chain.

The token is designed to streamline the different types of yield-bearing tokens, making it easier to integrate them into Defi protocols. It comes after the successful deployment of 25 previous Ethereum token standards.

Referred to as the tokenized vault standard, ERC-4626 aims to provide wide-scale benefits across Ethereum’s DeFi network. The token also creates a shared interface for coins held in vaults or smart contracts that draw liquidity from deposits of asset tokens for yield farming strategies.

Notably, the token standard will be implemented at the next Ethereum fork upgrade following approval from Ethereum developers.

The new standardization follows the launch of ERC-20 for fungible tokens (i.e., stablecoins and governance tokens), ERC-721 and 1155 for nonfungible tokens (NFTs), and BSC-20 for the Binance Chain’s compatible token, among others.

ERC-4626 cofounder, Joey Santoro also expressed delighted with Yearn Finance integration. He also noted that the move would serve a level of legitimacy and encouragement to other protocols in the space.
