The platform you mentioned is still under_developement. It's a startup based ICO .

maybe OTC is under development but trades, borrowing and funding are working

I got airdrop and Bounty from them and now building the exchange bot for the Russian market https://bitcointalk.org/index.php?topic=5184045.msg52435562#msg52435562

I need 1 more month to finish it

how to synchronise it with the exchange app. Link : https://wallet.localcoin.is/

https://wallet.localcoin.is/ it is web-wallet can be connected to the public nodes or your own node the core is here https://github.com/LocalCoinIS/LocalCoin-core/releases

but I strongly recommend using app for your pc, it is much safer.

I like the whole idea or DEX, looks really promising
