/*

TRUST, a cutting-edge platform integrated with Telegram messenger, has been created to offer a secure environment for users to explore the world of decentralized finance.

Trust focuses on ease of use by enabling solutions for users through the means of telegram bots. We have already launched the TrustMix Bot before token launch, while the remaining four bots will be launched after the token drop. Please refer to our website and read the whitepaper for more information.
