An algorithmic stablecoin pegged to the US Dollar, issued on the TRON blockchain and backed by crypto collateral

USDD (Decentralized USD) is an algorithmic, over-collateralized stablecoin native to the TRON blockchain, designed to maintain a 1:1 peg with the US Dollar. It's managed by the TRON DAO Reserve and backed by a combination of crypto assets.

How It Works

USDD operates through an algorithmic mechanism similar to DAI, where users can mint USDD by depositing crypto collateral. The TRON DAO Reserve maintains a basket of assets including TRX, BTC, and USDT to back USDD and maintain its peg.

Key Features

  • Over-Collateralized: Backed by crypto assets with a collateralization ratio exceeding 100%
  • TRON Native: Primarily operates on the TRON blockchain
  • Reserve System: Managed by TRON DAO Reserve with transparent on-chain collateral
  • Cross-Chain: Available on multiple blockchains through bridges

Considerations

As an algorithmic stablecoin, USDD's stability depends on its collateral management and market mechanisms. The history of algorithmic stablecoins (like UST/Terra Luna) highlights the importance of understanding the underlying mechanics and risks.
