## What Is 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.

## Who Are the Founders of USDD? 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.

## What Makes USDD Unique? 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.

## How Is the USDD Network Secured? 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.
