Recently, there is a new development regarding stablecoins worth paying attention to. A certain exchange wallet has launched an activity based on USDD, and the operation logic is quite straightforward — stake 100 USDD to participate, completed in just 2 minutes, with the ability to redeem at any time, and practically no additional thresholds. This is quite friendly for beginners.

What’s truly interesting behind this is the optimizations made in the USDD 2.0 product itself.

**Security is the key point**. USDD adopts an over-collateralization model, with all transaction records and collateral assets publicly verifiable, allowing users to check in real-time. It has passed 5 audits by CertiK and Chainsecurity, which are industry-recognized endorsements of credibility in the stablecoin space. This mechanism effectively alleviates investors’ concerns about de-pegging risks.

**The design for price stability is also noteworthy**. USDD 2.0 achieves precise USD pegging through the arbitrage mechanism of PSM (Peg Stability Module) and 1:1 slippage-free exchanges. Based on its upgraded performance, the price remains essentially stable around 0.999, even amidst recent frequent fluctuations in the stablecoin industry, demonstrating relatively solid performance.

**Liquidity support** is critical for price stability. Currently, the TRON version of PSM has nearly 50 million in liquidity reserves, with liquidity in the Ethereum and BSC ecosystems continuously replenishing. Sufficient liquidity means large transactions are less likely to impact the price, providing tangible security for users.

Overall, this product has made efforts in three dimensions: security architecture, price stability, and liquidity, offering investors a relatively reliable participation pathway.
