"Blackmoon’s CEO, Oleg Seydak, is also the CEO of Gram Vault, the Swiss custodian, and the companies plan to partner in order to supply large investors with a marketplace in which they can sell their tokens.
According to the Blackmoon’s chief operating officer, Sergey Vasin, consequently, contrary to the number of exchanges that managed sales of futures-like instruments based on Grams, Blackmoon will be the only marketplace to sell real Grams directly from legitimate TON investors as soon as the mainnet is live. Vasin said:
“Exchanges that earlier announced selling grams actually listed some kinds of derivatives. We don’t mind that — at the end, they will have to look for liquidity to deliver what they promised to their users, and they will run to buy grams from us with a premium.”
Blackmoon is apparently connected to Telegram itself through the one of the exchange’s co-founder, Ilya Perekopsky, who is also the vice president of the secretive messaging app company that allegedly stands behind the $1.7 billion Telegram Open Network (TON) project."
