Ellipal Titan has an option to import private keys.

Caution:
Recently I imported a (single) priv key from a paperwallet into Titan wallet (qr scan). Surprise: It generates a wrong pub address! Every other wallet I've tried generates the correct address, - but not Titan!

I contacted support and gave them all the screenshots with detailed explanations, but the support guy doesn't understand how paperwallets work. He thinks it has to do with the derivation path. The support guys don't seem to know the difference between a private key and a seed.

I posted it on Reddit: Instead of fixing the problem they deleted my post! It's a bug in the code that they don't want to admit!

There's another user on reddit who has the same problem: https://www.reddit.com/r/ELLIPAL_Official/comments/1i0fisn/import_of_old_dogecoin_private_key_not_workinghelp/
