Fidelity Investments is set to launch a U.S. dollar-backed stablecoin, FIDD, in early February 2026 on the Ethereum blockchain. According to NS3.AI, the stablecoin will be issued by Fidelity Digital Assets, which gained approval as a national trust bank from the Office of the Comptroller of the Currency (OCC) in December 2025. This development signifies Fidelity's strategic entry into the regulated stablecoin market, utilizing Ethereum's robust infrastructure.
