Seed phrase LN Umbrel into Sparrow Wallet

[Khaosan]

Hello

The Lightning Network seed phrase created for me by the LN Core application on Umbrel is not recognized on Sparrow.

Does anyone have a solution?

Thanks

Hi @Khaosan

I’d suggest following this guide here:

@DarthCoin

• This method will NOT restore your LN channels, only the onchain wallet! To restore funds from LN channels you still need to do the “normal procedure” explained in the point 1 in this guide.
• Install Sparrow desktop wallet
• Go to Cryptography Toolkit and download the HTML file onto your computer.
• Open that HTML file in “offline mode” (no internet) and select “aezeed Cipher Seed Scheme” from Tools. Then go to the 2nd tab “Decode Mnemonic”.
• Paste your 24 words into the “Mnemonic” field.

Select BIP84 format

• Select format BIP84 native segwit and wait a bit to be decoded.
• Copy the zprv displayed into the field “HD node root base 58”
• Open (already downloaded) Sparrow wallet app and select “new wallet”
• In the “Keystores” select “new imported software wallet”
• In the next window that will open, select “Master Private Key BIP32” and paste that zprv key you get it from the cryptography tool and click “import”. It will show you that is a m/84/0/0 derivation path (as it should be, to restore all your addresses and txs used previously in Umbrel).
• Click on “Import Keystore” and it will go back to main window of the wallet app where you can see all the wallet config. Click on “apply” and will prompt you to set a password to encrypt your local wallet file.
• Sparrow app will start scanning all your keys and txs and it will be displayed after a while in the “Transactions” tab. Patience, it will take some time.
• For a faster, secure and private connection is better to connect your Sparrow wallet app to your node. Just follow the instructions in “Umbrel - connect wallet - sparrow” and you will use directly the blocks and indexes from your own node.
