NFT usernames in Telegram

A service for selling usernames appeared in Telegram
⠀
Pavel Durov announced the launch of the Fragment trading platform.📱
Users of this platform can buy and sell names in the messenger. The user name will be given to the one whose maximum bid will not be outbid within a week.

The starting price depends on the length of the user name: the shorter the name, the higher its price. For example, the minimum amount for a four-letter name is 10,000 Toncoin (about $19,000).
⠀
Fragment service is built on the TON blockchain. And all user names will be represented in the blockchain as non-fungible tokens (NFT), their ownership will never be challenged, and the cancellation of the transaction will not be possible.
⠀
Names can be stored in crypto wallets, as well as put up for sale not only on Fragment, but also on any NFT trading platform that will support the Telegram Auction Platform.
