USDD has achieved significant milestones in its first year of upgrades, with its total value locked (TVL) surpassing $1 billion, according to reports by Messari and TechFlow DeepTide. The stablecoin's growth is attributed to its multi-chain deployment and sustainable revenue model, which have positioned it among the top ten stablecoins. USDD's strategy focuses on offering higher-than-average savings yields through USDD Earn and sUSDD, with sUSDD's TVL exceeding $310 million. The upgrade has transitioned USDD from an algorithmic model to an over-collateralized model, enhancing stability and user confidence. The Smart Allocator has generated over $9 million in cumulative earnings, reinforcing USDD's reputation as a yield-bearing USDT. With 462,000 unique wallet addresses, USDD demonstrates a strong user base and is poised to become a solid financial infrastructure through ecosystem integration and community governance.
