**The ERC-4626** tokenized vault standard is a standard protocol for tokenized vaults and is built on the [ERC-20](https://iq.wiki/wiki/erc-20) token standard. The standard was created to unify the technical parameters of yield-bearing vaults, making development, integration, and interoperability easier for vaults. It is meant to consolidate and standardize development efforts around “ERC-20 token strategies” such as borrowing & lending, [farming](https://iq.wiki/wiki/yield-farming), and [staking](https://iq.wiki/wiki/staking).

# Overview

The Tokenized Vault Standard, ERC-4626 officially went live on March 18, 2022[\[2\]](#cite-id-zsrxvgdxtdr). The Ethereum Comment Proposal 4626 for the ERC-4626 standard was created by Joey Santoro[\[9\]](#cite-id-gago61i8n3q) — founder of [Fei Protocol](https://iq.wiki/wiki/fei-protocol), who partnered with [Ethereum](https://iq.wiki/wiki/ethereum) developers transmissions11[\[4\]](#cite-id-1plkjnrti88), Jet Jadeja[\[5\]](#cite-id-lz5sd6wbwme), Alberto Cuesta Cañada[\[6\]](#cite-id-kjfocm06ix), and Señor Doggo[\[7\]](#cite-id-flbnliq4pcm).

## ERC-4626's Purpose

The lack of standardization for tokenized vaults presents challenges in integration and composability. Without a standard implementation, protocols must create their own adapters for lending markets, aggregators, and other interest-bearing tokens, resulting in errors, increased attack risks, and wasted development resources. Establishing a standard for tokenized vaults would streamline integration efforts, leading to more consistent and secure implementation patterns.[\[3\]](#cite-id-tk6f3onfuj)

ERC-4626 was developed with the goal of creating a standard that enhances composability and interoperability. To simplify the integration of yield-bearing tokens and address vulnerabilities, the team opted for a scalable and user-friendly approach. [\[8\]](#cite-id-vr7xtqa8b9j)\


# 4626 Alliance

The 4626 Alliance is a group of leading protocols and applications that share the mission of supporting the development and deployment of`ERC-4626` vaults:

The Alliance group was created to foster collaboration between [DeFi](https://iq.wiki/wiki/defi) projects and push the adoption of the ERC-4626 standard. Members of the 4626 Alliance establish a common bounty board for “4626 essentials.” They are voted on/built individually/jointly by members of the Alliance. [\[10\]](#cite-id-0uj2i5wtbr6)[\[11\]](#cite-id-p65ph88eane)

The Alliance Group also funds a common vehicle to distribute the costs and outsource through bounties the development of these “4626 essentials.” Each member of the Alliance commits $3k or more for this purpose. Alliances are also responsible for promoting the ERC-4626 standard through publication and events, and lastly, they create and maintain an open-source ERC-4626 resource library.
