# Audits

Beyond the harsh internal scrutiny to which we subject all of our codes, we retain Certik on a monthly contract for the express purpose of auditing our unique code bases. When deemed necessary, we also reach out to external auditing firms to provide additional reassurance.

## 28 May 2021

In developing Reaper Farm, we implemented changes to Yearn's contracts. We added state for profit/loss tracking, support for tokens and deposits that require tax, and deposit caps. These additions were all audited by Solidity.Finance.

They found no vulnerabilities. You can find their report [**here**](https://solidity.finance/audits/ReaperFarm/).

## 08 Nov 2022

Our multi-strategy vaults have undergone an extensive Certik audit with **no critical risks**. All identified risks have been resolved or have been acknowledged and are being actively managed by our team. The full report is available below.
