Introducing Composer Actions

- Create frames while you're writing a cast
- Discover new actions right in the app
- Available on Warpcast mobile
- Developers can now build and submit an actions for listing

Here's a demo of the new animated GIF action (!) by @0xconca.eth featuring a GIF from @miguelgarest.eth.

okay, this is smart:

- protocol: open; everyone can build their own actions
- product: retention; users don’t need to go anywhere else to find the content
- users: easier to cast; everything will be at one click
