USDD

USDD is a decentralized, over-collateralized stablecoin that is designed to be pegged 1:1 to the US dollar with enhanced stability and transparency. It aims to deliver security, decentralization, and stability within the crypto ecosystem. USDD is available to seamlessly integrate into DeFi platforms, offering a reliable and transparent asset that empowers users.

With seamless DeFi integration, efficient liquidation processes, collateral auctions, and a Peg Stability Module (PSM) to ensure market stability, the USDD ecosystem is designed for long-term growth, empowering users while safeguarding the protocol through real-time monitoring and community-led decision-making.

USDD was originally launched on May 5, 2022 on the TRON blockchain. Currently, USDD is a decentralized stablecoin. Its minting process is entirely decentralized rather than controlled by a single entity.

USDD stands out as a decentralized, over-collateralized stablecoin designed for stability, transparency, and sustainable yield. It balances stability and yield, delivering the best of both worlds as a yield-bearing stablecoin. How Many USDD Coins Are There in Circulation? As of April 2026, the circulating supply is approximately 1.5 billion tokens. USDD does not have a predefined maximum supply, as it is a decentralized stablecoin intended to maintain a 1:1 peg with the US dollar, with supply adjusting based on demand.

Any stablecoin’s security relies heavily on the stability of the assets that underpin it. As such, the USDD protocol over-collateralizes the protocol with highly liquid assets, including TRX, sTRX, USDT, and WBTC.

In order to keep the currency stable when its reserve assets’ values change as a result of adverse market conditions, the protocol’s monetary policy allows it to adjust the reserve asset ratios dynamically.
