USDD is a stablecoin issued by the TRON DAO Reserve. It’s pegged to the value of the US dollar and aims to provide a reliable, decentralized cryptocurrency for blockchain transactions. USDD can be used for payments, trading, staking and as a value store.

USDD is backed by a number of cryptocurrencies, including Bitcoin, Ethereum and TRON. To ensure stability and security, the reserve is over-collateralized, meaning that it holds more assets than the amount of USDD currently in circulation.
