Anchorage Digital Bank N.A. began institutional custody for xU3O8 on Sept. 16, 2026, becoming the first federally chartered crypto bank to offer custody for tokenized uranium. Issued by Uranium.io, xU3O8 represents beneficial ownership of physical uranium ore concentrate, or yellowcake, stored at Cameco facilities. Archax serves as trustee through a U.K. trust structure, while ownership is mapped on the Etherlink network. Cameco is responsible for safeguarding the uranium in certified facilities and periodically publishing proof-of-reserves audit results. Anchorage is regulated by the Office of the Comptroller of the Currency, allowing clients to hold xU3O8 in segregated, bankruptcy-remote accounts alongside bitcoin and cash equivalents. The token trades at about $5.66, giving the market a total value of roughly $9 million. The offering comes as renewed interest in nuclear power, including from artificial intelligence data centers, draws attention to digital access to real-world energy assets, although the market remains small.
