According to data from Artemis, the circulating supply of USDD has increased sharply from $452.23 million at the end of November 2025 to $728.50 million at the beginning of March 2026, a growth of approximately 56% in just three months. However, this increase was not linear. In December, the supply gradually grew, then surged in January 2026, reaching a peak of around $778 million on January 25. After this period, the supply slightly decreased and stabilized between $720 million and $750 million until early March.
USDD is a decentralized stablecoin issued by TRON DAO Reserve and backed by over-collateralized crypto assets. Unlike centralized stablecoins like USDT or USDC, the expansion of USDD’s supply is mainly driven by demand within the TRON ecosystem and related DeFi protocols. An increase in stablecoin supply often indicates growing liquidity in the crypto market.
