Looks good however you should ask the team if they prefer Ledger or L as the qualified import. We should pick one and stick to it.

Can we switch to using one qualified import alias, either L or Ledger?
I'd pick L, seems pretty obvious to me.

I've changed it everywhere in: 47eaafa

Is that something we want to do?

[smelc]

In favor of L over Ledger 👍

Since - generally speaking - we don't allow SRPs on main, you'll need to wait for cardano-api to be released and updated to merge.

A net improvement, thank you 🙏

I'm approving, but you'll need to wait for a release and update of cardano-api to merge.

LGTM. You can squash the commits. Also we can't merge yet until we have another release of cardano-api.
