[GUIDE] Recover your namecoins (and testnetcoins) sent to bitcoin addresses

[jackjack]

Your namecoin sending wallet is at /home/jackjack/wallet.dat
Your bitcoin receiving wallet is in your default bitcoin directory (if not, use pywallet --datadir option)

0. Download my pywallet fork and exit namecoind
1. In console 'cd /path/to/pywallet/'
2. Run './pywallet.py --dumpwallet' and find

Code:

        {
            "addr": "The Bitcoin Address you sent namecoins to", 
            "hexsec": "privatehexkey64characterslong", 
            "label": "", 
            "sec": "5xxxxxxx"
        }

3. Run './pywallet.py --importprivkey "privatehexkey64characterslong" --importhex --namecoin --datadir /home/jackjack/' (if testnetcoins, replace --namecoin with --testnet)
4. Restart namecoind with the rescan flag

Your coins are now again in your Namecoin wallet, and you can even use that Bitcoin address as a Namecoin address
I hope this will help someone one day

I absentmindedly sent a few NMC to an address generated by bitparking to deposit BTC. Can your trick work in this case or do I need to have control of the bitcoin address the coins were sent to? Where does "privatehexkey64characterslong" come from?

[jackjack]

Indeed, you need to control the bitcoin address to do that trick

But the bitparking admin is used to recover those coins, just send him a mail with the details he asks: http://dot-bit.org/forum/viewtopic.php?p=1337#p1337
