In the stablecoin sector, USDD is centered around decentralization and over-collateralization mechanisms, aiming to maintain stability and transparency on-chain. Compared to traditional centralized stablecoins, USDD places a greater emphasis on asset security and the system's risk resistance capabilities, providing DeFi users with more reliable options for trading, storing value, and on-chain applications. As the cryptocurrency market matures, stable and trustworthy decentralized stablecoins will become an important foundation for ecological development.
