Just thinking out loud: is there a world where there could be one signer managed per user managed by a third party that apps could use instead of creating a signer per app? 

Have to look a bit further into this, but the thinking is that paying for a signer per app turns me off from using a lot of excellent apps

Sounds like a wallet - feels like an anti goal for FC. If we are managing our own wallet across different apps, at that point things become both simpler and harder depending on if you’re crypto native or not

There’s also probably some ocap stuff that can be done

Have one app with on chain signer that allows having infinite ephemeral signers

you sign a message with key on any app, it’s sent off to the signer app, verifies, re-signs with on chain key, and sends it to fc. But this sounds like a wallet too in some ways
