Hello @osiastedian, ty for your PR.
Could you please fill the path field (instead of null) ?

Hi @tdejoigny-ledger ,

TBH I'm not sure what path to put there.
Do you mean tap root derivation path like this? /86'/57'/0'

https://github.com/osiastedian/ledger-app-syscoin/blob/develop/tests_mainnet/test_bip86.py#L20

Bitcoin has null path.

Our app is a fork of the app-bitcoin-new repo.

Hi @osiastedian ,

I'm talking about the derivation path. For example qtum app is also a Bitcojn clone and has his derivation path different from null. Some of Bitcoin clones are directly built from app-bitcoin (legacy app), they don't have a dedicated repository.
