There was a problem hiding this comment.
I am really fond of extensive usage of phantom-type diambiguation to Key, Index, Passphrase types. It makes comparing BIP-32/44 with this implementation really straightforward, especially reading the intention and the way of deriving different keys
The PR needs rebase and squash

just wonder why for Index and Key there is Depth and DerivationType phantom-type used, respectively. And here, you are relying on Symbol (in a sense making phantom-type like specialization open) rather than on data. Using :
data PassphrasePurpose = Encryption | Generation
would have some drawbacks? Maybe we want to extend it somewhere outside ant making not visible in this module?
There was a problem hiding this comment.
Exactly for the reason you mention, using a symbol leaves the type quite open which makes sense for types that are rather general like "Passphrase". On the contrary, the Index and Key have a very precise semantic for which we already know the spectrum, and therefore, we can be explicit and have a closed typed.
So, it's just slightly more convenient to have symbols than sum types and we get almost the same guarantee. Typos are still possible but in such case, GHC will probably yell at you that types don't match.

There was a problem hiding this comment.
and we do not want to hide encodeAttributes in the implementation of encodeAddress and just choose the proper implementation by adding in the Cardano.Wallet.Binary :
data AddressScheme = Random | Sequential
and just declare what we want at this this level?
There was a problem hiding this comment.
Nope because the implementation for encoding attributes of random addresses doesn't solely depends on the public key unfortunately. There are extra params that we don't want to bring in the context of the Binary module. The inversion of control is therefore desirable here (cf the prototype).

ah, ok, I see now 👍 still maybe some testing of encodeAddress would be desirable

We have golden tests testing just that actually :)

There was a problem hiding this comment.
I notice there was a passphrase check in the previous version.
This function is no longer failable (partly because the isHardened check is obviated by the Index type).
What happens when the key encryption passphrase is wrong?
There was a problem hiding this comment.
I left a comment about that but I'll extend it. This has been left to the caller as controlling the password would require to either keep a hash of the password in memory (which was a wrong design decision) like before, or have an access to the keystore / password vault. This is a responsibility of the wallet layer calling those derivation primitives.

There was a problem hiding this comment.
So it's ok to crash with error when the index is greater than a billion or so?
There was a problem hiding this comment.
In practice it shouldn't happen because we can't create such index. Our Index type is completely opaque and the only way to create indexes is through the Bounded and Enum instance (Enum which also throws at runtime if succ is called on maxBound, as specified in the base built-in). Again, the caller would have to check that prior to calling those primitives whether it makes sense.
We know it can't happen, but it's better to have a rather clear invariant here than doing a partial pattern match like Just res <- ... , which would not be very helpful if we ever violate this invariant.

mempty <> should not be necessary according to the semigroup law, or am I missing something?

It's not indeed. This is just the result of copy/pasting + tweaking.

Yes. Making sure that this code can run just fine.

This is just to minimize merge conflicts as we rebase. It makes sense in the context of a PR only
