The head of the Gram Vault custodian, Sergey Vasin, filled out an application for listing on the Poloniex exchange before the SEC filed a lawsuit against Telegram.
According to Vasin, who is also a Blackmoon COO exchange, Gram Vault stores 50% of tokens from the first round and 75% of tokens from the second round of sales.
He also added that Telegram does not work directly with exchanges. The document was at the disposal of CoinDesk.
SEC asked Telegram for information on possible Gram trading on the Coinbase, Poloniex, Bittrex, Huobi, Binance, Blackmoon and Liquid exchanges. Only the last two and Coinbase Custody previously announced token support.
Recall that the SEC lawsuit has already forced Telegram to postpone the launch of TON in the spring of 2020.
