Uranium token xU3O8 has added custody, exchange access and lending support since launch, according to source material and recent reports.
xU3O8 has moved beyond being a tokenized claim on uranium into a broader market structure, with custody, exchange access and lending support layered on after launch. In source material published by Metals.io on Oct. 28, 2026, the issuer-backed project is described as having added the infrastructure needed for both institutional and retail participation, though the underlying legal and custody arrangements remain essential to the token's design.
According to the source material, xU3O8 is not uranium itself but a record of beneficial ownership of physical uranium oxide, U3O8, stored at a regulated Cameco facility and held in the account of Archax Ltd as trustee. The article says proof-of-reserves is updated regularly with Cameco statements so the onchain token remains tied to verified physical backing. Background context supplied with the request adds that Uranium.io describes xU3O8 as fractional ownership of physical uranium ore concentrate recorded on Etherlink, an EVM-compatible Tezos layer-2 network, and that issuer documentation dated 2024-12-02 said each token initially represented one ounce, though later minting means it may now represent a proportional share of the pool rather than a fixed one-ounce entitlement.
The source material says individual holders can use a wallet, while institutional holders need regulated custodians. It identifies Hex Trust as having added support for Etherlink and xU3O8 in August 2025, and Anchorage Digital as following in September 2026. Verified enrichment also notes a Sept. 16, 2026 report that Anchorage expanded institutional custody to Etherlink and tokenized uranium, which is consistent with the source's chronology.
