According to PANews, OP Labs protocol engineer Mofi released the Granite Network Upgrade proposal to address vulnerabilities discovered by third-party security audits, and user assets were not threatened.

The proposal includes smart contract upgrades and L2 hard forks to improve system stability and performance, and initiate a permission fallback mechanism to avoid instability.

If the proposal is passed, the upgrade is scheduled to take place at 16:00 UTC on September 10, and has been coordinated with Base and Conduit to be launched on the internal development network and Sepolia Superchain.
