From blockchain.info seed to bitcoin-qt

[arixos]

Hi guys,

I set up my full node and now want to move wallet from blockchain.info to my bitcoin-qt.

Blockchain.info is only providing the 12 words seed. I found a couple of guides about using Mnemonic code converter to extract BIP32 extended private key and how to generate it, which I did and got the long string starting with "xprv"
.
But the bitcoin-qt is not accepting this generated "BIP32 extended private key" and gives an error:

"Invalid private key encoding (code -5)."

Any idea?

Thanks

Bitcoin Core will only import "WIF" private keys ie. the individual private keys that start with "5", "K" or "L"... you can't import a master private key (aka "xprv").

So, if you use the Mnemonic Code Convertor you have to copy all the private keys from the bottom of the page. You'll need to figure out exactly which addresses actually have coins and import those (Don't forget your change addresses!!)

If you have a LOT of private keys to import, your best option is probably to just send all the coins from b.info to Bitcoin Core using a standard transaction.
