One of our main challenges was setting up the custom Orbit chain with Avail DA. Navigating the configurations, establishing secure connections, and ensuring smooth data availability took careful planning and iteration. While it was initially time-consuming, this process offered invaluable insights into the intricacies of combining an L3 chain with a robust data availability layer. Tackling these challenges not only enhanced our technical understanding but also refined our approach, resulting in a more resilient and efficient platform.
