Thank you for the insight.
Connecting a wallet and interacting with the application is a big deterrent for adoption.
May be Rocca wallet will solve this issue as it is being designed to provide web2 experience for web3 products.
IMO you should integrate Rocca when it is launched, get the app live on mainnet, show some adoption and then apply for the grant. xGov is mostly focused on funding public good projects.
So it would a boost for your project if you can show some adoption.
All the very best !
