Toncoin (TON) is the cryptocurrency behind The Open Network—a blockchain initially developed by the team of the messenger Telegram. After Telegram abandoned the project due to regulatory pressure, the developer community continued the development of TON as an open project. TON is characterized by high transaction speeds, scalability, and low fees. It supports smart contracts, NFTs, decentralized applications (dApps), and has its own ecosystem. A key feature is its integration with Telegram, which offers the potential for mass adoption. Toncoin is used for paying fees, staking, and voting in network governance. In 2024–2025, the coin gained popularity due to community support and the growth of the DeFi sector.
