Why frames?

1) Increase distribution
Discovery through feeds, search and notifications in apps people already user daily; deploy once work across a growing ecosystem of apps with integrated wallets.

2) Mobile wallet UX
Minimize taps; 100% reliability; no app switching

3) Notifications
Access to mobile notifications without the need for a full-blown native app or clunky PWA.

4) Minimal work
Builds on your existing web app; no TestFlight

#3 is great, immediate access to notify is a huge shortcut for devs
