# Audits

At Strata, we place the utmost importance on the robustness and security of our smart contracts. To uphold this standard, we undergo thorough third-party audits to detect any vulnerabilities, logic flaws, or inefficiencies. These detailed reviews by leading security firms strengthen our protocol’s security and build greater trust with our users.

### **Strata Protocol**

Strata completed an extensive, multi-phased audit process to ensure the highest level of protocol security. The initial audit round was performed concurrently by [Cyfrin](https://www.cyfrin.io/) and [Guardian](https://guardianaudits.com/), followed by a second audit phase conducted by [Quantstamp](https://quantstamp.com/). Additionally, differential audits of the redemption fee, cooldown and accounting mechanisms were conducted by Cyfrin and Quantstamp.
