​
Definition

An Ethereum tokenized-vault standard defining a common interface for vaults holding a single underlying ERC-20 asset.

​
Why it matters

Ethereum-specific terms explain its execution environment, standards, accounts, and scaling roadmap.

​
How it works

The standard defines methods for depositing assets, withdrawing shares, and checking vault balances. It includes functions for calculating interest rates and yield distribution in a consistent way. Protocols implementing this standard must adhere to specific naming and logic, enabling easier integration for front-ends and other smart contracts.

​
Real-world example

Yearn Finance and many lending protocols are moving toward ERC-4626 for their vault structures.

​
Advantages

  • Standardized yield interface
  • Higher DeFi interoperability
  • Simplified integration for developers

​
Limitations

  • Implementation requires rigour
  • Newer standard gaining adoption

​
Common misconceptions

  • People think it is a specific investment fund, but it is just a set of rules for building one.
  • Many assume all DeFi vaults are ERC-4626, but many legacy protocols use custom code.
