After thorough analysis and considering community feedback, we have decided to postpone the upgrade announced on November 29th, 2023. Our decision is based on the new test results, assessment on the risk, and discussion with the experts and community.

We appreciate your understanding and cooperation in this matter. Ensuring the stability and security of the BNB Chain remains top priority, and we are committed to taking the necessary steps to achieve this goal.
