Imagine a stable digital asset combining the best of traditional finance with decentralized blockchain technology, offering full transparency, robust security, and attractive returns. With a total supply of 258.14 million tokens and a protocol total value locked (TVL) of $283.08 million, Decentralized USD (USDD) is a next-generation decentralized stablecoin designed to maintain a 1:1 peg with the US dollar. Unlike traditional stablecoins managed by centralized entities, USDD leverages blockchain technology, community governance, and robust collateralization to ensure stability, transparency, and security.

As of March 2025, the total market cap of all stablecoins in the crypto market sits at over $230 billion. Among them, while Tether (USDT) takes the lead, USDD is one of the largest stablecoins by market cap within the TRON ecosystem.
In this guide, you'll learn what USDD is, how it works, its core features, and how you can migrate to the latest USDD version to benefit from enhanced stability and decentralization.
What Is Decentralized USD (USDD) Stablecoin?
USDD is a decentralized, over-collateralized stablecoin in the TRON ecosystem. Currently, the minting rights of USDD2.0 are given to users; previously, USDDOLD was issued by the TRON DAO Reserve. It maintains a consistent value equal to one US dollar, backed by crypto assets like TRX, USDT, and other digital assets. Being backed purely through technology, USDD offers transparency and decentralization to its users.
Why Was USDD Created?
The cryptocurrency market experiences frequent volatility. USDD provides a stable digital asset, allowing you to transact, invest, and hedge risks without exposure to significant price fluctuations. USDD's decentralized nature removes intermediaries, reducing centralization risks and providing users with complete control over their assets.
What's New in the Upgraded USDD?
The latest version of USDD introduces significant enhancements designed to improve security, decentralization, and overall protocol stability. Here’s what's new:
-
Enhanced Security and Risk Management: The upgraded USDD protocol implements advanced risk management tools and secure liquidation processes to swiftly address under-collateralized positions. These mechanisms help maintain stability even during volatile market conditions.
-
Dynamic Collateral Adjustment: Collateral ratios now dynamically adjust according to market conditions, ensuring continuous adequate collateralization. This proactive management reduces the risk of liquidation and further safeguards user assets.
-
Peg Stability Module (PSM): The Peg Stability Module is now integrated, facilitating zero-slippage stablecoin swaps between USDD and other stablecoins such as USDT. This feature maintains the stablecoin's peg more efficiently, offering users seamless transactions without additional fees.
-
Community-Driven Governance: The new USDD enhances community involvement by empowering users to actively participate in governance decisions through proposals and voting. This ensures that the stablecoin evolves according to collective user interests and market demands.
-
Improved Transparency and Auditability: All collateral and transaction activities supporting USDD are fully auditable on-chain, enhancing trust and reliability. Open-source smart contracts and comprehensive third-party audits further reinforce transparency and security.
How Does USDD Stablecoin Work?
USDD maintains its stability through several interconnected mechanisms:
-
Over-Collateralization: USDD is backed by collateral whose value exceeds the circulating supply, including highly liquid crypto assets such as TRX and USDT. This safeguards the peg to the US dollar.
-
Collateral Management: Users deposit collateral into vaults to mint USDD. These vaults dynamically manage collateral ratios to stay above safe thresholds, adjusting according to market conditions. Real-time monitoring alerts users about potential risks, allowing proactive measures to prevent liquidation.
-
Liquidation Process: If collateral falls below the minimum threshold, the system triggers liquidation, auctioning collateral assets to cover debts. Participants in these auctions can obtain assets below market price, contributing to overall system stability.
-
Peg Stability Module (PSM): Allows seamless, zero-slippage exchanges between USDD and other stablecoins at a fixed 1:1 rate. This crucial module helps maintain the USDD peg, even during market volatility.
-
Decentralized Governance: USDD operates without a centralized authority. The community proposes and votes on all protocol decisions, aligning stablecoin evolution with user interests.
-
Transparency and Auditability: All activities, collateral reserves, and transactions are recorded publicly on blockchain explorers, enabling real-time audits and fostering trust.
-
Enhanced Security: Through rigorous third-party audits, smart contract security, and over-collateralization, users maintain complete control without centralized interference.
-
Seamless DeFi Integration: USDD integrates smoothly with decentralized finance platforms, facilitating lending, borrowing, staking, and trading.
