USDD is an algorithmic stablecoin issued by the TRON DAO Reserve. It debuted in May 2022 on the Tron Network. USDD targets a 1:1 peg to the US dollar and relies on a mix of cryptocurrencies to maintain over-collateralization. It was built to respond to worries about price swings across the crypto market. 

The currency’s creators state that USDD has “perpetual existence and zero dependence on any centralized entity,” and they express a desire for it to become the most decentralized currency available.

What are USDD’s key features and how does it work?

USDD’s notable features center on its price stability and the mechanism behind it. Its stability is supported through algorithms alongside Super Representatives. In practice, Super Representatives supply a price oracle for USDD. A decentralized set of block validators, through voting, determines what exchange rate they believe USDD should be at the moment. The incentives are designed to encourage honest behavior, since they hold a substantial amount of TRX and benefit from delivering correct pricing. Also, validators get a minimum of .5% of transaction fees from any TRX/USDD swaps, plus a fixed fee for swaps involving USDD.

Separately, TRX is also used as a safety buffer for USDD. It serves as the reference currency for pricing USDD, with that pricing handled through the Super Representatives, helping reduce the chance of price swings. In this setup, TRX absorbs volatility. 

What can USDD be used for?

USDD is intended to work like many other stablecoins, including participating in and moving across compatible chains in DeFi, Governance, GameFi, and trading it for other assets.
