IDEX listing was not made by W12 team - someone from the community must have filled the application and they listed it as the project is real - however, IDEX should contact the founders/developers before starting the market, that way IDEX just looks silly. Coinbene confirmed W12 IEO on their Telegram channel, as well as Sistemkoin, haven't checked the others to be honest. Let's see how the sales go and to the moon!
