Damus iOS has never had a signer and people seem ok with it 🤷‍♂️ The way notedeck is being built is that the chrome (microapp host) is the signer, and the apps will need permission from the user eventually Basically just like how web browser signers work today

Its a problem for all signers. Private zaps, coinos deterministic wallet and probably more features he will build needs custom functions that signers need to implement I have support for private zaps in amber because amethyst had it too but no other clients ever implemented private zaps decrypting
