We faced several challenges while implementing FomoFactory. Initially, our goal was to create an extremely user-friendly platform that worked seamlessly with any wallet and simplified the complex wallet-related UX. However, we encountered compatibility issues with different wallet frameworks, necessitating the addition of custom wrappers and adapters to ensure functionality with tools like the Uniswap swap widget. Despite these efforts, the mobile experience remained suboptimal. Integrating the Coinbase Smart Wallet helped streamline some processes, but it required even more customizations to work smoothly with the Uniswap widget.

In our second iteration, we added support for Farcaster frames. While some frameworks made this easier, we had to make numerous adjustments to accommodate the limited size of the frame payload and the very restricted user flow. This required significant effort to ensure a smooth and intuitive user experience despite these limitations.
