At Concordium we understand that security is vital for the users, that is why we have asked, Kudelski Security, to performed a code audit on our blockchain and, as we approach Mainnet, we are really proud to share the results with you!

Concordium and Kudelski Security performed threat modeling, code review, and “scenario based” assessment of the underlying code and logic of the Concordium software.

During the code review, Kudelski found no critical or high-risk scenarios that put the tokens of the system at risk and they made a number of suggestions to improve overall documentation, and conformance to best practices.

Following the completed review, and during follow-on tests, scenarios were discovered in which unused network messages and test code could cause availability concerns on the network even though these errors would not cause a loss of funds. They completed a follow-on review, looking specifically at the network code and identified a few issues that the Concordium team fixed.

You can read the whole report here.

At Concordium we are grateful with Kudelski, and we look forward to continuing the joined efforts to bring trust into our ecosystem.
