Applications built on the ERC4626 vault work with the high yield ERC4626 vault, making integration and innovation much easier.
Anyone familiar with NFTs knows the token standard ERC721. But have you ever caught up with ERC4626? According to DeFi Llama data, TVL (Total Value Locked) for all DeFi protocols is close to $ 193 billion.
Since the decentralized financial explosion in the summer of 2020, a concept called “yield agriculture” has emerged. Users deposit funds on platforms such as compound lending protocols, and when deposits are lent out, some of the profits reminiscent of traditional bank interest payments are rewarded.
However, yield farming was not attractive to individual users without significant capital or conceptual knowledge, so a “yield aggregator” (a set of smart contracts that pools user funds to optimize yields) was introduced, these soon became known as vaults.
However, these vaults had no implementation standard and had some complexity. Yield Aggregators, Vaults, Credit Markets, and Native Yield Tokens have always been implemented in minor variations. Building apps on the vault was difficult, and potential security vulnerabilities emerged. Scaling was also limited.
The Vault Standard
Created on December 22, Ethereum Improvement Proposal (EIP) was led by Joey Santoro, the founder of Fei Protocol, and aimed to change it.
The main purpose of this proposal was to establish a robust implementation standard for vaults, but also outlined the potential security implications of vaults in the absence of specific standards.
EIP4626 was approved on March 18th. Since then, numerous DeFi protocols such as Yearn Finance, Balancer, Rari Capital, and mStable have begun implementing ERC4626 on vaults. (Approved EIPs are called ERC or Ethereum Requests for Comment.)
All packages constructed on the ERC-4626 vaults are workable with all different yield-bearing ERC-4626 vaults, so with those contracts now clean to integrate, new improvements sprung up round yield strategies.
With ERC-4626, vaults are actually categorised into fundamental categories: transferable and non-transferrable.
In transferable vaults, a consultant ERC-20 token is issued to the user. This token could constitute the fraction of the vault pool owned with the aid of using the user. Non-transferrable vaults don`t use tokens.
Establishing standardized vaults open up new opportunities for interoperability among one of a kind protocols. This may also pave the manner for accelerated compatibility of protocols throughout a couple of blockchains.
