Mammix. He's done awesome wallet work in the past and is very knowledgeable in this area. If he's not super busy, I have no doubt he could port the HYPER wallet over to the more efficient newer code seen in things like RBIES.
Mammix is the one I contacted, they are working on RBIES wallet atm.
I can contribute some Hyper for a new wallet if we can find a developer.
Excellent, thanks for your willingness to help the community.
. He's done many wallets in the past and does a lot of custom things. Not sure if he does work for others though.
