Escodex literally just announced it's closing before it actually closed. It stated the fact that it would be shutting down around 2019. It started that this was as a result of legal restrictions. Alongside it's untracked listings.
Well, enough on the reason why it is currently inactive, now if you'd like to know some brief history and characteristics of this exchange.
Escodex is a decentralized exchange which originated from Estonia. It had an initial trading fee of 0.1% per transaction. It didn't support Fiat currencies before it closed. Actually,I am hoping to hear news about it coming back to activity.
In fact,the Twitter account doesn't even exist any more this means that this exchange is not going to be active anytime soon.
