CIP-30: Permission Sets about cips HOT 4 OPEN

This feels like wallets asking users which CIP-30 extensions to enable for a given dApp?

@Crypto2099 good idea to have an issue for this requirement. I agree it will be important: maybe important enough to create a CPS for it.

@Ryun1 something seems familiar about it... didn't something like this come up when discussing hierarchies of CIP-30 functions? (Apologies for not being great in this field; just trying to connect with prior discussion in the many PRs we have for CIP-30.)

Perhaps but could also be taken a step further and higher to even the "core" CIP-30 functionality such that:

• I am a user who wants to connect my wallet to a site to signData with my wallet but DO NOT want to give that website access to create a transaction on my behalf
• I want to give a site the ability to read my wallet state getUTxO without the ability to generate and request signature for a transaction on my behalf

etc :)

So adding optional permissions per endpoints?

I do quite like this as an idea, but I don't really see a backwards compatible way to integrate this with existing CIP-30 implementations. I think we would be better off pursuing this as an extension, to something like a CIP-90?. I did have this in the rationale at some point... that CIP-90 would allow for "privacy preserving connections" but I must have removed at some point.

The counter argument is; does not sharing public info from wallet to site that useful? because if not then what are they sharing? why connect? - if they are signing (signData or signTx) then they are revealing their public keys where the dApp can index chain for the wallet's public info.

I believe we had the discussion somewhere about IF users should have the ability to explicitly permission dApps based on extensions -- but this was decided against - I will try and find the thread.

I am a user who wants to connect my wallet to a site to signData with my wallet but DO NOT want to give that website access to create a transaction on my behalf

The site would be able to identify your wallet from your signature thus allowing them to index chain for the wallet's UTxO set.

I want to give a site the ability to read my wallet state getUTxO without the ability to generate and request signature for a transaction on my behalf

Id argue that CIP-30 almost allows this behaviour, a user could always refuse a signTx action. The only difference is that the site is allowed to request it as much as they like, but I dont really see this being much of an issue.
