I tried several times now. The checksum of the seed words the Lightning Node app gives me seems not to be valid. How is this possible?
(tried to enter them in a Coldcard and Sparrow..)
Thanks for your help and kind regards
lightning node is separate thing from sparrow or cold card. Sparrow does not support lightning.
I do not believe cold card does “really” either and probably shouldn’t. Hardware wallets are for storage.
Shouldn’t the seed words be standardised and interoperable between different wallets?
LND uses Aezeed. It can be converted using this tool, but be careful to download the tool and go off the internet if you use it. Personally I would only go that route if I needed to recover my funds from a crashed LND node. The very technical explanation for why Aezeed was chosen is here.
Solid answer, thank you. I wasn’t aware of Aezeed.
My intention was to check if I wrote down the seed correctly on an offline device like Coldcard Q.
