Well, Why only for ETH?
Soon Waves, Eos, VET, and other are going to have Dappps working on it, if we need a mobile wallet to use this Dapps, then, why not a wallet for all?
like a Ledger nano mobile to interact with the Dapps through mobile.
+ all native features of wallets: Fast, Secure, Backups, Transaction history, Qr code display, more than 1 transfers per time, actual value in prefered currency, not very heavy, annon...
and an important thing: Easy to use!
Good luck with your project!
Thanks for the answer. We deeply respect the blockchain technology and the safety of use, so the development of a hardware wallet is not a fast process. We believe what Ethereum is the most promising cryptocurrency for common use, so we focused on it. After finishing work with Ethereum and ERC20 tokens to the proper level, integration of other currencies is planned
