GRAM (GRM) is the ticker denoting the principal cryptocurrency of the Telegram Open Network (TON) issued by a global messaging platform Telegram in 2019. The ICO campaign was conducted in 2018 with up to $1.7 bln investments collected.  

The TON blockchain was built as the platform for micro payments. 

The launch of the TON blockchain was scheduled for October 2019. However, the US Security and Exchange Commission’s (SEC) filed a lawsuit seeking to put sale of tokens on ice because these tokens were not registered as securities by the TON and Telegram. At this point, the operational status of the coin is unclear as long as the settlement with the SEC is pending. 

Interestingly, that sale of Gram futures is open with one of the Chinese platforms.
