By integrating Mod, you also get Farcaster Frames support automatically

There is a Mod, Farcaster Frames Render (opens in a new tab) that integrates Farcaster Frames into your app. In order for the Farcaster Frames to work, you need to provide a onSendFcFrameAction property to the RichEmbed resolvers object. An example of this function implementation using neynar can be found here (opens in a new tab)
