Decentralized Payments

The USDD protocol aims to provide the blockchain industry with the most stable, decentralized, tamper-proof, and freeze-free stablecoin system. USDD circulates on TRON, Ethereum, BSC, and other networks via the cross-chain protocol BitTorrent Chain. Similar to TRC20-USDT, it caters to users' needs by offering them a fast and affordable experience on TRON.

Over-collateralized Asset

USDD is secured by the over-collateralization of multiple mainstream digital assets (e.g. TRX, BTC, and USDT). The total value of collateralized assets is significantly higher than that of USDD in circulation with the collateral ratio set at 310%, far exceeding the 100-120% ratio of other stablecoins.

Reduced Volatility

Most cryptocurrencies are significantly more volatile than traditional financial assets. Stablecoins allow users to significantly reduce volatility in times of a market downturn without having to trade funds back to fiat currency, enabling users to keep their funds on the blockchain rather than in a bank.

How is USDD decentralized?

USDD is minted by the whitelisted institutions of the TRON DAO Reserve (TDR) through burning TRX. Its value is backed by the over-collateralization of highly liquid crypto assets under the TDR, including BTC, USDT, USDC, and TRX. The circulation and use of USDD are free from the intervention of any centralized parties. Similar to BTC and ETH, USDD grants its holders full ownership, meaning that no organization or individual has access to freeze users’ USDD.
