With this approach, I think it makes more sense to call these "Account Labels"

I think account labels makes sense, adding context of when an account should be used. One potential one I see missing from this list is identity - an account that contains a users preferred identity credentials.


Account profiles are labels that are used to decribe an authorized account's capabilities and intended use. Each authorized account that is returned in [`authorize`](#authorize) request response can include a list of these profiles. The dapp endpoint can use these labels in combination with the account's list of [`features`](#feature-identifiers) to determine how each acount should be used.

Do we need both mutable and immutable, or does the absence of one imply the other?

I could go either way, I am not certain what is best. both have drawbacks I think

A) With both mutable and immutable, its more explicit. tho it also adds the incompatibilities (mutable and feepayer cannot also be immutable)

B) With only mutable, the absence would imply immutability. feePayer would imply mutable as well which makes sense. primary would not imply mutable, it would need to be specified.

C) With only immutable, the absence would imply mutability. feePayer would be incompatible with immutable as it would not make sense to have an immutable fee payer.

I am leaning towards option B here, only having mutable. primary (and identity) accounts imply immutability if not specified. feePayer and mutable would be allowed but redundant.

I can think of one benefit for option C - if a wallet labels nothing. The default (and backward-compatible) behavior for an unlabeled account would be mutable.

yeah thats a good point. gonna mull on this a bit more.

- A mutable account can be used as a writeable account in transactions and will allow transactions that change its state. This profile is incompatible with the `immutable` profile, a single account will never specify both `mutable` and `immutable` profiles.
- `immutable`
- An immutable account may be used as a read only account in transactions, but will not support transactions that attempt to change the accounts state. This profile is incompatible with the `mutable` profile, a single account will never specify both `mutable` and `immutable` profiles.
