Why TON, who needs it, and how this network’s rules differ from the rest — short and to the point.
Not abstract “crypto risks,” but the rules of this network. For each — what happens, and how Mitilena shows it before the Send button.

Exchanges often accept TON on a shared address and tell clients apart by a comment on the transfer. Without the right memo the funds can reach the venue but not your account.

One wallet has two spellings: EQ… (“bounceable”) and UQ… (“non-bounceable”). A transfer to an EQ address of a wallet that does not exist yet returns — the network “bounces” it.

Anyone can send a jetton or NFT to a TON address with a note like “you were credited 500 USDT — claim on the site.” The site asks you to connect a wallet and sign — and drains everything.

The messenger’s built-in wallet is convenient, but the key there is tied to the account and app updates. If Telegram is hijacked, funds inside it are at risk.
Hundredths of a TON for the coin; for jettons about 0.05 TON is reserved and the surplus returns.
A comment on the transfer that an exchange uses to find your account. To an exchange — usually required; to a personal wallet — not needed. In Mitilena the send form has a comment field — paste the memo the venue shows on deposit.
Yes — Tether issues USDT on TON directly since 2024. Check the contract address: fakes with the same name are common.
The key does not depend on the messenger account or its updates. If Telegram is hijacked — Mitilena is untouched. Bots connect via TON Connect; you sign each operation separately.
