Importing ledger account into Polkadot vault

[Daanvdplas]

Hello, I am trying to import my ledger polkadot address into my Polkadot vault but I'm having a hard time deriving the right path and resulting to the correct address. There is also little to be found except the standard m/44'/354'/account'/0'/0'

Hey @Daanvdplas, I think that you'll find useful this issue

No, I still don't know now how to manually create the derivation path to import my ledger created address into my Polkadot vault.

Please explain

@Daanvdplas, I think the other account looks really suspicious. Please be cautious.
I strongly advise against doing this. The mnemonic should not be placed anywhere with an internet connection.

Have you check this code?

You'll need to set your mnemonic and then you can configure the derivation path here.

You can check with the testing mnemonic first:

ledger-polkadot/tests_zemu/tests/common.ts

export const APP_SEED = 'equip will roof matter pink blind book anxiety banner elbow sun young'

@ftheirs could you confirm that this is the way?

[ftheirs]

I haven't checked that on my end but that tool was developed by Jaco from PolkadotJS and we also have some tests for key derivation over here:

I will have a look this weekend, will not try the other stuff because I also think it looks suspicious
