On Jan 15, 2020 CODEX exchange was closed. The announcement for closing business was published in advance so that the exchange’s customers were able to withdraw their funds. The reason why CODEX stopped its operation is changes in the European regulations.
The exchange is dead
I like that the platform is fully legit and really can confirm the safety of any funds here. It's not so big and popular place, but I may say the exchange is providing good performance, it's worth to trade with.
