WSPN (Worldwide Stablecoin Payment Network), a digital payment solution provider, announced that its stablecoin WUSD has completed the smart contract upgrade from V1 to V2. The new version of WUSD uses the smart contract technology provided by Fireblocks and introduces a number of features, including: asset mistransfer recovery mechanism, role-based access control, institutional-level address blacklisting and other security features, as well as optimized DeFi platform integration and multi-chain compatibility. WSPN said that the modular design of the V2 version will lay the foundation for the introduction of advanced features such as soul-bound token SBT and identity authentication in the future. At present, all V1 version tokens have been migrated at a 1:1 ratio, and users only need to import a new contract address in the wallet to continue using.
