Justin Sun is the founder of the TRON, which is behind the USDD stablecoin. Launched on May 5, 2022, USDD is on the TRON blockchain and is also available on Ethereum and BNB Chain.

USDD is issued and redeemed via smart contracts on TRON. This allows for fast and secure transactions, as well as transparent and verifiable records of USDD issuance and redemption. It also lets users join [staking pools]. A decentralized community of stakeholders oversees the management and development of USDD, and makes decisions on behalf of the wider community via the TRON DAO Reserve (TDR). The TDR is the principal custodian of USDD and is responsible for preserving the value of the currency and maintaining a stable exchange rate. It was established as a separate financial organization to protect the Tron ecosystem against the effects of extended economic downturns, financial panic, and unstable exchange prices for both centralized and decentralized Tron stable currency. Its primary roles are as a lender of last resort, a regulator of risk-free interest rates, a manager of liquidity through the release and restriction of funds, and an implementer of monetary and exchange rate policies.

USDD stablecoin is intended to maintain a fixed exchange rate of 1:1 with the US dollar. This implies that for every USDD coin in circulation, a corresponding amount of US dollars is set aside in reserve. $2 billion worth of USDD has been authorized, while $1.25 billion worth of coins remain authorized but not yet issued. As of June 2023, the total supply of USDD is around $741K, and the total collateral is around $1.2 billion. These are mainly held in TRX, BTC and TUSD.

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 BTC, TUSD and TRX. 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.

USDD is listed on crypto exchanges, including [KuCoin], [PancakeSwap (V2)], [Uniswap (V3)], [SushiSwap], [Gate.io], [Poloniex], [Huobi], [Bybit] and more.
