What is ERC-4626 tokenized vault?

An Ethereum standard that defines common interfaces for depositing assets, issuing vault shares, and redeeming shares for underlying assets.

Why it matters on your return

Standardized vaults make the share-for-asset exchange explicit: you deposit one asset and receive shares whose value tracks the vault. That structure is why the deposit is commonly treated as a taxable exchange and the redemption as a second one.

Example

You deposit 10,000 DAI into an ERC-4626 vault and receive 9,800 shares. Under the exchange position, the DAI is disposed of at $10,000 and the shares take that basis; redeeming them later for 10,600 DAI is a $600 gain.

Are ERC-4626 vault shares a different asset for tax purposes?

Under the common position, yes. The share represents a claim on the vault, not the specific asset you deposited.
