# Technical Partners

Napier v2 runs on purpose-built contracts. We treat security as a product feature and brought in top builders and reviewers to protect user funds.

### Commitment to Security

* We consulted Erik Arfvidson and Kasper Pawlowski — key operators behind Euler’s daily security opeerations. They oversaw a \~$4M security budget for Euler v2 and coordinated external partners across audits and response workflows.
* Architecture & gas efficiency: We engaged vectorized.eth (creator of Solady) to harden core architecture and improve gas efficiency.

### Code Audit and Review

We commissioned multiple rounds of code reviews, security audits, formal verification, and code competitions with industry leaders including Cantina, Spearbit (Cmichel, Kurt), Sherlock, Pashov Audit Group, Winney and yAudit.

For an in-depth look at these audits, please see below.
