rejectProposalUpgrade

Function Type: external
Access Control: isSuperUser
Function Signature: rejectProposalUpgrade()

Cancels a pending upgrade proposal, resetting the upgrade governance state to allow for new proposals.

Description​

This function allows the current superUser to cancel any pending upgrade proposal at any time during the 7-day waiting period. It provides a critical safety mechanism to reject upgrades that may have security issues, compatibility problems, or are no longer desired.

Access Control​

Modifier: isSuperUser

Only the current superUser can reject pending upgrade proposals, ensuring that only the current governance authority can cancel proposed changes.

Security Features​

Immediate Cancellation​

  • No time delay required for rejection
  • Immediate effect upon successful execution
  • Allows for rapid response to discovered issues

Clean State Reset​

  • Completely clears the pending upgrade proposal
  • Resets the acceptance timestamp
  • Allows for immediate new proposals with different implementations

Workflow​

  1. Access Control: Validates that the caller is the current superUser using the isSuperUser modifier. Reverts with InvalidUser if not authorized.
  2. Proposal Reset: Clears the proposed implementation address immediately.
  3. State Cleanup: Resets the timeToAccept timestamp to 0.
  4. Security Measure: Prevents unwanted contract upgrades and maintains current implementation.

            console.log("Upgrade proposal rejected successfully");
            // Refresh interface
            location.reload();

            console.error("Failed to reject upgrade proposal:", error);

};

Workflow Integration​

Standard Rejection Workflow​

  1. Issue Identification: Discover problems with proposed implementation
  2. Impact Assessment: Evaluate severity of issues
  3. Stakeholder Communication: Inform community of rejection
  4. Execute Rejection: Call rejectProposalUpgrade()
  5. Plan Resolution: Determine next steps for addressing issues

Upgrade Lifecycle​

State Management​

The rejectProposalUpgrade function serves as a critical safety valve in the upgrade governance system, ensuring that problematic upgrades can be quickly canceled while maintaining the integrity of the time-delayed governance process.
