USDD

Overview

USDD is a decentralized stablecoin issued on the TRON blockchain and designed to track the value of the US dollar at a 1:1 ratio. It launched on TRON in May 2022 and later expanded to additional networks including Ethereum and BNB Chain. Issuance, redemption, and collateral management are handled by the TRON DAO Reserve.

The TRON DAO Reserve holds reserve assets such as TRX, BTC, and USDT, which it states are used to support USDD's price stability. The token originally used an algorithmic design, but USDD 2.0, released in 2025, moved to an over-collateralized model in which users deposit assets such as TRX to mint USDD. Because a stablecoin's peg depends on its collateral composition and operating mechanism, reviewing reserve disclosures and the underlying structure is important.
