Security Audit

Download Audit Report

The critical subjects covered in our audit are authentication, checks enforcement, and adherence to the specification. Security regarding all the aforementioned subjects is high.

Some issues of low severity have been addressed by Euler by accepting them as part of the specification and improving the documentation.

In summary, we find that the codebase provides a high level of security.

It is important to note that security audits are time-boxed and cannot uncover all vulnerabilities. They complement but don’t replace other vital measures to secure a project.

About Euler Ethereum Vault Connector

Euler implements Ethereum Vault Connector, a general framework for vaults interoperability for the purpose of arbitrary lending markets creation.

Euler v2 is a modular lending platform with two main components at launch: 1) the Euler Vault Kit (EVK), which empowers builders to deploy and chain together their own customised lending vaults in a permissionless manner; and 2) the Ethereum Vault Connector (EVC), a powerful, immutable, primitive which give vaults superpowers by allowing their use as collateral for other vaults. Together, the EVK and EVC provide the flexibility to build or recreate any type of pre-existing or future-state lending product inside the Euler ecosystem.


ChainSecurity delivered an exceptional audit for our project. Their meticulous approach and quick responsiveness enhanced our security and provided crucial insights. We greatly appreciate their dedication and excellent communication throughout the process.
