From their FAQ section:
Is DUSK a security token?
No. DUSK is not a security because it presents a protocol-regulated inflationary mechanism and provides no profit or dividends whatsoever. It absolves the same role of Ether in the Ethereum ecosystem.
My question was in another. They will have smart contracts for creating tokens like Ethereum? But this is anonymous coin, so SEC will allow create security tokens on anonymous blockchain?
I suppose not. In general this is doubtful. On the other hand, the SEC does not have global power in the field of cryptocurrency.
