Audits of Gnosis Chain and Related Infrastructure |
{% hint style="info" %} Most Audits were completed prior to the rebrand from xDai Chain to Gnosis Chain, and will refer to the xDai chain as well as the STAKE token, the previous governance token of the chain (the chain is in the process of transferring to GNO-only security). {% endhint %}
Completed: October 1, 2021
Conclusion: During the assessment one critical issue was found and fixed following the intermediate report. The remaining issues were of low severity and were fixed accordingly. The communication with the team was very responsive.

The token constitutes a VFA in terms of Maltese law. Please contact [email protected] to request access to the document.

Contracts: Version 0.1.0 addresses issues present in audit. https://github.com/poanetwork/posdao-contracts/releases/tag/v0.1.0
