Key Takeaways

• Euler invested $4 million in security, far exceeding industry standards.
• The v2 code underwent 29 audits by 12 different security firms.

Euler, a decentralized lending protocol, today announced the completion of an unparalleled security process for its v2 platform. Euler DAO invested roughly $4 million in security measures, including the hiring of top security experts, rigorous testing methods, and extensive audits with 29 code audits from 12 different firms.The security investment was a substantial sum compared to other DeFi projects which typically allocate much lower budgets in the low six figures, the company stated. The efforts aim to make Euler v2 one of the most secure DeFi protocols ever built.Euler said high-profile security experts were involved from the early stages of development to help identify and address potential vulnerabilities, including security engineers from Certora, ERC-4626 pioneer and developer of the Yield protocol Alberto Cuesta Cañada, as well as Cmichel, StErMi, leading security engineers from Spearbit.Once each module was completed, it underwent rigorous internal and external audits. Euler v2’s robust security framework includes a modular architecture that isolates potential vulnerabilities, enhancing auditability.The audit process was complemented by advanced testing methodologies, including fuzz testing and formal verification, which were developed in collaboration with security experts.The company noted that the protocol underwent 29 audits conducted by 12 top-tier firms. Euler’s multi-layered approach ensures that the protocol’s core functions remain secure under all conditions.

As part of its commitment to security, Euler engaged Cantina to organize the largest code audit competition ever held. The event attracted over 600 participants globally, with researchers competing for a $1.25 million prize pool.Modular approachEuler is set to launch its revamped version, Euler v2, in the second quarter of 2024, the team shared in a press release. Euler v2 adopts a modular structure, introducing components like the Euler Vault Kit (EVK) for customizable lending vaults and the Ethereum Vault Connector (EVC) for integrating with ERC-4626 vaults.Euler v2 aims to offer increased flexibility for users to create custom lending markets and strategies. The new version also seeks to rebuild trust after the $200 million exploit last March.The team said previously they had learned from the attack in the previous version, prioritizing flexibility and scalability in v2.
