According to Justin Sun, traders can now exchange USDT for USDD via the PSM module without incurring on-chain gas fees, offering zero cost swaps and an annual yield of 20%. This development is significant for traders looking to maximize profits by reducing transaction costs and earning high returns on USDD holdings.

According to Justin Sun, the annual yield subsidy of 20% for USDD is justified by its status as a fully decentralized stablecoin on the TRON blockchain. Sun highlights that USDD is the only decentralized option for the $60 billion market on TRON, emphasizing its unique value proposition for traders and investors. This perspective may influence trading strategies that prioritize decentralization and high yield opportunities.
