TON
TON is the chain that shares an address book with Telegram. Of everything here, it is the one already inside the app you are using. It carries USDT and Gram, settles in about five seconds, and is the natural destination when the person you are paying is a Telegram contact rather than an address you were sent.
Why Gram and not TON
The native coin appears throughout this wallet as Gram, because that is the ticker it carries end to end here — icon, price, balance and history all key off the same symbol. TON in this wallet means the network; Gram means the coin. Keeping the two words apart is why nothing has to be translated between screens.
Paying a person, not an address
You can send to a @username instead of an address. The wallet resolves it to the recipient’s own vault, and nothing about the transfer identifies your other wallets to them.
USDT here, USDT everywhere else
USDT on TON is its own credit, like every other chain’s. Moving it to or from TRC20, BEP20 or ERC20 is a real transfer, quoted with the fee inside it.

Questions
Do I need Gram to send USDT on TON?
No. The fee is settled inside the operation, in the token you are sending.
Why does the wallet say Gram where other apps say TON?
Gram is the coin, TON is the network. The wallet tickers the coin as Gram and uses that name everywhere, rather than translating it on some screens and not others.
Can I send to a Telegram username?
Yes — to a @username or to any address. Sending to a username does not reveal your other wallets.
