We can expect this hardware wallet integration in version 1.5.0 or 1.6.0! (Hopefully)
Lisk has been a bit delayed with deadlines which has pissed a lot of the community off, though they are making a tremendous amount of progress in the front end development, the user experience, networking and marketing...
Of course we are waiting for the infamous ‘side-chain development kit’ — which will enable JavaScript developers to build their own blockchain and tokenized economy..
In the mean time LiskHQ/Lightcurve are building the foundation for which the decentralized apps will operate on.
This question was about hardware wallets.
