In simple terms, this means Penpie contracts can no longer be upgraded instantly. Any contract upgrade now requires a minimum 3-day lock period — once an upgrade request is submitted, it can only be executed after at least three days. This strengthens security, preventing scenarios where attackers swiftly upgraded contracts with malicious versions to execute an exploit. With this safeguard in place, any scheduled upgrade to Penpie’s core contracts will undergo a mandatory 3-day review period, giving us ample time to assess the changes and cancel any upgrade if necessary. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.penpiexyz.io/security/timelock.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
