When it comes to stablecoins, many people think of USDT and USDC, but the emerging player USDD is also proving itself with real actions.

**Safety is the top priority**

The design concept of USDD 2.0 is quite straightforward—reserve assets must far exceed circulating tokens. What are the benefits of doing this? It essentially provides the entire system with a safety net. Even with market fluctuations, there is ample backing. Transaction records and reserve details are all on-chain, transparent to the point of being unable to conceal anything. Audit giants like CertiK and ChainSecurity have reviewed it, and the conclusion is that the structure is solid and trustworthy.

**How to keep the price pinned at 1 dollar**

USDD uses a tool called PSM (Pegged Stability Module). The core logic is to allow you to exchange it for USDT or USDC at a 1:1 ratio anytime, no complicated steps. As soon as the price fluctuates, arbitrageurs will immediately intervene to bring the price back. This is why USDD can survive relatively steadily amidst various storms on chains like TRON, Ethereum, and BNB.

**Liquidity is guaranteed**

The over-collateralization ratio has now exceeded 200%, with collateral including various stablecoins and easily tradable tokens like TRX. Running on multiple public chains, it reaches a wider user base and has better compatibility within various DeFi ecosystems. These designs are combined to ensure that USDD is not only stable but also user-friendly.
