Zellic conducted an audit for Tiki Labs Inc. from September 19th to October 7th, 2022.

Our general overview of the code is that it was very well-organized and structured. The code coverage is high, and tests are included for the majority of the functions. The documentation was adequate, although it could be improved. The code was easy to comprehend, and in most cases, intuitive.

We applaud Tiki Labs Inc. for their attention to detail and diligence in maintaining incredibly high code quality standards in the development of Audius.

Zellic thoroughly reviewed the Audius codebase to find protocol-breaking bugs as defined by the documentation and to find any technical issues outlined in the Methodology section of this document.

Specifically, taking into account Audius's threat model, we focused heavily on issues that would break core invariants such as the Governance proposals, both in terms of user interaction with them and in the way they execute. Moreover, we paid special attention to the way the protocol staking happens, such that all the contracts that are supposed to be able to stake can do so in a seamless manner and that the stakeholders are always secured.

During our assessment on the scoped Audius contracts, we discovered six findings. Of the six findings, one was of high severity, three of medium severity, one of low severity, and the remaining findings were informational in nature.

Additionally, Zellic recorded its notes and observations from the audit for Tiki Labs Inc.'s benefit in the Discussion section at the end of the document.
