Akchex wallet used to be a Waves supporting wallet that held onto every Waves token and the Waves coin itself. It used to be a recommendable wallet for users as it supports users to access the wallet on its web platform and mobile application.
Currently the wallet doesn't offer it's services and cannot be accessed in any way possible. Other Waves wallets are out there to be used and Akchex isn't recommended. In my research so far, there has been no phishing websites claiming the website but that can't be trusted for long. Users are advised to be careful with or before accessing any wallet that comes with the name Akchex so as not to fall victim to a scam
