Telegram Mini Program developers can exchange Telegram Stars for TON tokens or buy Telegram ads at a discounted price. The announcement said: "Bot developers who offer digital goods and services, as well as creators who monetize their channels through paid posts, can now use the Telegram Stars they earn to earn Toncoin rewards or buy Telegram ads. Telegram doesn't actually take any commission from Stars transactions, so only taxes and payment system fees are payable. When a user transfers Stars to a Telegram ad account, Telegram offers a 30% discount to cover all third-party payment system fees."
