Does someone known how to get the Bitcoin Core (the default Bitcoin wallet on Umbrel) public key ?
I tried to look for it on the differents directories of Umbrel but I didn’t find it (event in umbrel/bitcoin directory).
Umbrel is a LND aezeed wallet.
What do you want to achieve?
I would like to use my umbrel’s node public key for BTCPAY server in order to make on-chain invoice to my umbrel node.
- I would NOT recommend to do that, only in specific situations and ONLY when you really know what are you doing.
- Umbrel LND onchain wallet it should be used ONLY to open and close LN channels. Not to be used as a hot wallet.
- For a BTCPay server you could easily use whatever other offline onchain wallet (Electrum, Sparrow, Specter, hardware wallet etc), taking its MPK (master public key) and use it in BTCPay server.
- If you really want to ignore all previous points and go on using Umbrel onchain wallet, you have 2 options:
You were warned: do not use node onchain for other purposes than open/close LN channels.
Ok (I fully understood why I was asking for dangerous stuff while looking at https://guggero.github.io/cryptography-toolkit/#!/aezeed …), thank you for the explanation I will use offline onchain wallet…
Thank a lot
