Import Ledger Wallet - can not figure out the correct derivation path

[mt-gareth]

I am sorry to post here as I know this is not an issue with your app. But I am trying to get my wallet that made Ledger to be used by Polkadot Vault. I have imported the keys, and now I am just struggling to find the derivation path. In ledger it says 44'/354'/0'/0'/0' but that does not work, I tried //354/0/0/0 and some permutations of hard and soft around that but can not get it. Would anyone be able to point me in the right direction?

Ledger devices follow the de-facto standard BIP39 and BIP44. Substrate unfortunately is not BIP39/BIP44 compatible. Here is an open issue: paritytech/substrate#7824

@prybalko Isn't it possible to add the BIP32 derivations to Vault like Polkadot-JS UI does?

Currently the only alternatives Ledger users have if there's no updated app in Ledger Live is:

1. Wait
2. Build the app themselves (assuming the delay is the security audit)
3. Import their account to PJS-UI

Having the option to import in Vault would give users a valid, secure alternative.

@michalisFr it is possible for sure, we already have a ticket for that #812
I'll try to prioritise it.
