Custom Derivation Path for Bip39 Restore

[cyberpass2]

Hello,

I have a custom derivation path, but I can't seem figure out what format I should use in Electrum when i restore my BIP39 seed:

I have keys with the following path:

m/84'/1'/0'/0/0'

I've tried the following custom derivation in Electrum:

m/84h/1h/0h/0/0h

I am able to derive them in Ian Coleman's script. Im not worried I lost my funds or anything but I'd be more comfortable knowing I can sweep the transactions using Electrum.

After you input your BIP39 seed phrase on Elecrum and you checked ✔️ BIP39, click on native segwit (p2wpkh).

Yes. I did that, but I want to derive hardened addresses.

Electrum doesn't support hardened addresses, probably because of the way the wallet is designed (needs to be able to derive addresses from master public key).

So when you enter any derivation path, it considers it as the root and then automatically derives you keys at m/0/ and m/1/  (m/0/0, m/0/1, m/0/2, ... are main addresses, m/1/0, m/1/1, m/1/2, ... are change addresses). That way you can easily get the master public key of this wallet and then create a watch only wallet from it without needing the seed itself.

Your option is limited since you've used a custom non-standard derivation path.

Not in Electrum or even Sparrow, but you can import the master private key to Bitcoin Core via "descriptor". (equivalent to BIP39 tool's "BIP32 Root Key")
Import it like this (preferably to a blank wallet):

Code:

importdescriptors "[{\"desc\": \"wpkh(your_xprv_key/84h/1h/0h/0/*h))#00000000\",\"timestamp\": \"0\",\"watching-only\": false,\"active\": true,\"internal\": false,\"range\": [0,999]}

You should replace the checksum "#00000000" with one that'll be displayed in the error message about checksum mismatch or use getdescriptorinfo first.
To import the change addresses, import another with "internal: true" flag and chain_index (External/Internal) derivation path switched to from "0' to "1".
