The Ledger Nano S is partially supported by HWI.
Currently implemented commands:
getmasterxpubsigntx(with some caveats)getxpubsignmessage
Due to device limitiations, not all kinds of transactions can be signed by a Ledger.
- Transactions containing both segwit and non-segwit inputs are not entirely supported; only the segwit inputs will be signed in this case.
