We are storing private key on iOS into keychain and encrypted keystore on android (our web version will use web crypto or extensions)
We are also planning to do view only and seperate event signer
Hope that answers the question 😊
Discussion
How exactly are you storing one’s private key on iOS? Is it safe to enter my private key into your app?
as i said, we are saving it into the iOS keychain. Same place where natively in iOS you can save for example passwords. It's safe, but if you do not trust this, we are planning to do other options to sign in, so you can try plebstr later 😊
