According to an announcement by ‘The Open Network’ (TON), a decentralised blockchain initially designed by Telegram and abandoned by the platform in mid-2020, users of the messaging app can now send each other crypto via a new telegram wallet bot.
The "wallet" bot's initial release would allow users to send and receive Toncoins with no transaction costs, according to the developers. Users can also use their bank cards to buy Bitcoin and Toncoins through the wallet. They can then transmit Bitcoin (BTC) or Toncoin to other users by clicking on the "Wallet" symbol in direct messaging.
