Namecoin Forum

Hello.

I'm a noob who need some help.
How can I import my wallet from "old" Namecoin-Qt app to Electrum-NMC?
Do I need to manually extract and paste private keys to new wallet?

Thanks.

Extracting and importing private keys is certainly a way. But if you have a newer version of Namecoin-Qt, it uses an HD wallet; if you use "dumpwallet" from the console or namecoin-cli, you may see the "xprv" key in there - and I think you can try importing that into Electrum to get the full wallet. I have not tried it myself, though.

Note that importing a Bitcoin Core wallet into Electrum is something that's most likely going to get more thorough answers on a Bitcoin forum. (There shouldn't be anything Namecoin-specific involved.)
