On Ethereum there is at least Ambisafe's project Orderbook that does pretty much the same except far ahead, because:

a)Orderbook is already working decentralized exhcange.
b)Orderbook is an ICO platform that launched couple of dozens ICO's.
c)Orderbook actually holds patent for regulated token technology . https://www.newsbtc.com/press-releases/orderbook-announces-one-kind-regulation-aware-protocol-tokenized-securities/
d)Orderbook has implemented KYC/AML verification, Accredited Investor Status verification and DocuSign electronic signature. This is the best compliance tool set that is implemented by any exchange.
e)Orderbook is now in process of acquiring SEC licenses for private securities offering and public securities offering. And you can't even apply for those if you don't have all of the above mentioned technologies in place already working.


Also instead of ordinary ICO they do a private SAFT round. You can ask them by mail or in telegram support chat about it.
