Replying to Avatar Big Barry Bitcoin

I don't know enough about the secure enclave situation, or more specifically, the secure element in many modern smartphones.

1. Is it in many or just a few like the Google pixel?

2. Does software like BlueWallet use it?

3. How does it really keep data secure from malware? Does it limit access to the specific apps that created the data? Is there reliable anti-spoofing?

For apple, the enclave requires a faceID proof before it'll sign. But, afaik no btc wallets use them because the curve the enclave supports is secp256r1 (whereas bitcoin is k1).

I heard op_cat provides enough account abstraction to make it work, but, have not looked into if that's true or not.
