What's Included in Granite?
This upgrade is proposed in response to security vulnerabilities identified during a series of third-party security audits by Spearbit, Cantina, and Code4rena. None of the vulnerabilities have been exploited, and user assets are not and were never at risk. However, out of an abundance of caution, the permissioned fallback mechanism has been activated in order to avoid any potential instability while the vulnerabilities are patched. For more information on the permissioned fallback mechanism and the OP Stack's defense-in-depth approach to Fault Proof security, see the fault proof documentation.
The upgrade includes both a set of smart contract upgrades to fix the vulnerabilities identified in the audit as well as an L2 hardfork to improve the stability and performance of the fault proof system. In addition, we propose extending the capabilities of the Guardian and DeputyGuardian to set the anchor state for the fault proof system in order to prevent referencing invalid anchor states. Aside from implementing these fixes, the primary impact of this upgrade would be to reset user withdrawals at the planned time, similar to the initial Fault Proof upgrade.
