@USDD - Decentralized USD For years, stablecoins often experienced on-chain fragmentation. If you are on the Tron chain, you use Tron stablecoins; if you are on Ethereum, you use ERC-20 stablecoins. But by the end of 2025, these barriers are finally starting to break down.
Although the initial market focus was on the security model of USDD, the second revolution currently happening is equally important: radical interoperability.
'USDD 2.0' transformation
Earlier this year (January 2025), USDD underwent a significant internal upgrade to 'USDD 2.0'. While the promotional focus shifted to a fully over-collateralized decentralized stablecoin (OCDS) model, the real transformation for DeFi users lies in the Ethereum-native deployment achieved in September.
