They made an announcement thread on this forum[1], however, it is no longer active as it once was, it appears that they abandoned it now since they have their own governance forum.
It's good to see an exchange on Telegram because the project idea came as a Telegram fork, but I also believe it's the incorrect platform to develop an exchange that has to do with money. Telegram is one of the most popular platforms for fraudsters, not only in cryptocurrency, anybody can construct a similar bot and alter the username by just a letter, and anyone may become a victim. To some extent, I enjoy that they did not seek KYC, but it is a NO for me. DIscord would have been a better option.
