## TLDR - The Security Council is initiating a non-emergency action, - After that is complete, Omer Greisman from OpenZeppelin will be replaced by Steven Thornton from OpenZeppelin. - OpenZeppelin is a corporate member of the Security Council and this helps accommodate changing their representative. No actions need to be taken by users of Arbitrum One or Arbitrum Nova. We will update this thread as we progress through the steps of enabling the action and rotating the security council member’s keys. If you have any questions, please do respond on this thread!
