How it's made
Challenges we ran into One significant hurdle we encountered was integrating the paymaster and bundler services to sponsor user transactions, which was crucial for handling gas fees. The challenge was to ensure that users could complete transactions without worrying about gas costs, which can fluctuate and add complexity. We overcame this by using the Paymaster Client, which allowed us to sponsor user operations seamlessly. Additionally, we implemented fallback mechanisms that resort to direct transactions if the sponsored transaction fails, ensuring reliability and a smooth user experience.
