European stablecoin issuer AllUnity has launched USDAU, its fourth fiat-backed stablecoin and first pegged to the US dollar. The new token maintains a 1:1 peg through segregated reserves and expands the company's MiCA-compliant product lineup, which already includes euro, Swiss franc, and Swedish krona stablecoins. USDAU will debut across six blockchain networks: Ethereum, Solana, Base, Tempo, Arc, and Polygon. The multi-chain launch positions the European issuer to compete in the dollar-denominated stablecoin market while maintaining regulatory compliance under the EU's Markets in Crypto-Assets framework.
