I modified the joincoin code, to remove the internal tor. So now, you can use tor to connect v3 onion address nodes.

Just rebuild the code. Add this to config:

After you install the tor, you can run the wallet too.
You can connect to my node with this address: ukvewg7vjip46tir7dedmke6ncvalgrfecewoc6pzc4gcxj3fq7pytid.onion (my last block is: 1430193)

(start wallet with this command line parameter: )


If you want incoming connection, setup a hidden service to your torrc:
Start tor, read tordatadir/hidden_service/hostname file, add the hostname to joincoin config:
and run wallet.
