There probably will be a base token when they launch, but they've been focusing on building the primitives, not the token. The mainnet is not launched yet, but you can use the language, proofs and verifiers and of course all the infrastructure for developers. They have built for example anonymous voting infrastructure (AnonDAO).

It has nothing to do with Eth, Vlad is mistaken in this, they are not compatible with Eth, don't have a token on Eth nor use any infrastructure. They build it on utxo not account model. 

I am not sure how successful it is going to be, but I'm glad that they are actually building some very interesting stuff that did not exist before at all, they did not do any kind of scam raising of money or anything.
