ERC-4626
Also known as: Vault Token Standard, Yield Vault Interface, ERC-4626 DeFi
A tokenized vault standard for Ethereum that defines a uniform interface for yield-bearing tokens and DeFi vaults.
ERC-4626 is an Ethereum token standard designed to unify and standardize the interface for tokenized vaults that generate yield. By providing a consistent API for deposit, withdrawal, accounting, and asset-to-share conversions, ERC-4626 enhances composability across DeFi protocols. It facilitates efficient integration between yield aggregators, lending platforms, and DAOs. This standard simplifies development, reduces integration errors, and enables more predictable user experiences when interacting with yield-bearing assets like Yearn vaults or Compound deposits. ERC-4626 is built atop ERC-20, meaning it inherits fungibility while adding vault-specific logic.
