Based on the previous answers, it is clear that an audit was conducted three years ago. However, it is also important to know if any other audits have been conducted since then. To answer this question, I have checked with Slowmist and they have confirmed that they have conducted an audit of KLAY recently. The audit report can be accessed through the link provided. Therefore, it is safe to say that KLAY has undergone a recent audit, in addition to the one conducted three years ago.
