Answer: Building momentum around upgrades can be challenging when the user experience (UX) doesn't change much. However, there are still ways to create excitement and anticipation for the upcoming upgrade. For example, we can highlight the features and benefits of the upgrade, and explain how it will improve the user experience in the long run. Additionally, we can use social media to engage with our users, and provide them with updates on the progress of the upgrade. Finally, we can emphasize the importance of the upgrade by highlighting the fact that it will bring us on par with Ethereum, which is a major milestone for the Mumbai block time. By doing this, we can create a sense of excitement and anticipation for the upgrade, and motivate our users to stay engaged with the project.
