Not yet.
The existing App SDK is not further developed but archived.
Lisk now has 5 developer and working hard on a new App SDK.
Ok so before that we won't see any apps?
How difficult is it to implement some Ethereum apps into Lisk chain ?
Let's say Augur, wants to build a second version on Lisk.
So I'm not a developer. I think it is possible to experiment or work with the old code.
But the Lisk Devs means that a complete rewrite of the SDK code base is required.
And they can't give a guarantee that there is a full compatibility between the new and the old SDK.
