The ERC-4626 tokenized vault standard is a new standard for yield-bearing vaults on Ethereum. It provides a standard API for token vaults that represent shares of a single underlying ERC-20 token. This makes it easier for applications, plugins, and tools to integrate with vaults.
ERC-4626 vaults can be used to implement a variety of yield-bearing strategies, such as lending, staking, and liquidity provisioning. They can also be used to create more complex financial products, such as yield aggregators and decentralized asset managers.
Benefits of using ERC-4626 vaults
There are a number of benefits to using ERC-4626 vaults, including:
- Composability: ERC-4626 vaults can be easily integrated with other DeFi applications, such as DEXs and money markets. This makes it possible to create more complex and sophisticated financial products.
- Transparency: ERC-4626 vaults are required to provide transparent information about their holdings and performance. This makes it easier for users to make informed decisions about where to invest their money.
- Security: ERC-4626 vaults are designed to be secure and auditable. This helps to mitigate the risk of fraud and theft.
Definitions
- Vault: A smart contract that holds a pool of underlying assets and issues shares to users in exchange for their deposits.
- Shares: ERC-20 tokens that represent a proportional ownership stake in a vault’s assets.
- Underlying assets: The assets that are held in a vault and used to generate yield.
- Yield: The return on investment generated by a vault’s underlying assets.
- Yield-bearing strategies: Strategies that are used to generate yield on underlying assets, such as lending, staking, and liquidity provisioning.
How it works
ERC-4626 vaults work by allowing users to deposit assets into a vault in exchange for shares. These shares represent the user’s ownership stake in the vault’s assets. The vault manager is responsible for deploying the assets in a way that maximizes yield while minimizing risk.
Users can redeem their shares at any time for the underlying assets, subject to any withdrawal fees that the vault may charge.
Here is an example of how ERC-4626 vaults work:
- User deposits 100 ETH into a vault.
- The vault manager deploys the ETH into a lending protocol.
- The vault issues the user 100 shares, which represent their ownership stake in the vault’s assets.
- The user earns yield on their ETH through the lending protocol.
- The user can redeem their shares at any time for 100 ETH, plus any accrued interest.
Real-world use cases for ERC-4626 vaults
ERC-4626 vaults are still a relatively new technology, but they are already being used in a number of real-world applications. Here are a few examples:
- Yield aggregators: ERC-4626 vaults can be used to create yield aggregators that automatically invest user funds in the highest-yielding opportunities. This allows users to earn maximum yield on their assets without having to manage their own investments.
- Decentralized asset managers: ERC-4626 vaults can be used to create decentralized asset managers that implement a variety of investment strategies. This allows users to invest in complex strategies without having to trust a centralized intermediary.
- Institutional DeFi: ERC-4626 vaults can be used to make DeFi more accessible to institutional investors. By providing a standard API for vaults, ERC-4626 makes it easier for institutional investors to integrate DeFi into their existing investment workflows.

Conclusion
The ERC-4626 tokenized vault standard is a promising new technology with the potential to revolutionize the way that users earn yield on their crypto assets. By providing a standard API for yield-bearing vaults, ERC-4626 makes it easier for developers to create new and innovative financial products. It also makes it easier for users to choose the best yield-bearing solution for their needs.
