Hi.
Hich-tech products based project looks very interesting for me.
Is it necessary to use your wallet or any ETH wiil do?
Hello.
We don't have our own wallet. Any ETH wallet can be used (e.g.MEW)
I just saw a wallet on your site and decided that it's your own wallet.
That hardware wallet is our product

It's multicurrencial and can be used for our token too. And of course it's much safer than any on-line wallet.
You could have answered that it's necessary to use only your hardware wallet

It would be too much to say it's necessary. But many marketers use phrase "it's recommended" or "we recommend"

It sounds really softer.
We don't recommend it now because it'll launch market on the 3rd quarter of 2018.
And many people are still not ready for hardware wallet.
But if someone asks about it we can recommend our Redder because he really is safe and convenient hardware wallet.
