Apple prefers owning the end to end stack. So for crypto, a product-driven protocol is close to Apple's approach of software-driven hardware.
+1 as long as you build the product also. for apple: true but remember that being full stack when they started made a lot more sense. If it was easy for Meta to go full stack w hardware from scratch they would do it --> its hard if you don't start there, and its harder as time goes by to start there.
