TGC is a global, universal payment method designed to address issues in international trade. It operates as a decentralized third-party barter exchange platform that eliminates the need for a centralized system, enabling direct connections between trading parties. This enhances trade efficiency and resolves trust issues among the parties involved. As a new option for trade payments, TGC allows traders to avoid losses caused by fluctuations in the exchange rates of national currencies across different countries, thus enjoying the convenience of international free trade.
