    The ChugSplashDictator contract (glory to Arstotzka) has been deployed.

    FOLLOW THESE INSTRUCTIONS CAREFULLY!

    (1) Review the storage key/value pairs below and make sure they match the expected values:

        ${messengerSlotKey}:   ${messengerSlotVal}
        ${bridgeSlotKey}:   ${bridgeSlotVal}

    (2) Review the CURRENT and FINAL proxy owners and verify that these are the expected values:

        Current proxy owner: (${currentOwner})
        Final proxy owner:   (${finalOwner})

        [${
          currentOwner === finalOwner
            ? 'THESE ARE THE SAME ADDRESSES'
            : 'THESE ARE >>>NOT<<< THE SAME ADDRESSES'
        }]

    (3) Transfer ownership of the L1ChugSplashProxy located at (${
      Proxy__OVM_L1StandardBridge.address
    })
        to the ChugSplashDictator contract located at the following address:

        TRANSFER OWNERSHIP TO THE FOLLOWING ADDRESS ONLY:
        >>>>> (${ChugSplashDictator.address}) <<<<<

    (4) Wait for the deploy process to continue.
