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.
What xU3O8 represents
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.
Custody and access widened in stages
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. The article frames this as giving funds and treasury desks a familiar custody layer for holding the token, separate from the physical uranium custody structure.
On market access, the source material says xU3O8 launched on Uranium.io and later appeared on exchanges including KuCoin and MEXC. It highlights a July 30, 2026 Kraken listing as the most important exchange development so far, though not the first. The piece also says Uranium.io evolved into Metals.io in March, allowing xU3O8 to be traded alongside other metals including gold, nickel and cobalt, and that card purchases reduce the need for users to acquire USDC or manage a wallet first. Verified enrichment adds that Trilitech broadened its tokenized commodities push on Tezos with Metals.io on March 30, 2026.
Lending added a DeFi use case
The source material says xU3O8 was added as collateral to a Morpho lending market in November 2025, first through Oku and later through Monarch. Holders can supply xU3O8 and borrow USDC against it, which the article describes as enabling liquidity without selling the uranium exposure. Verified enrichment independently notes a March 31, 2026 report that tokenized uranium lending launched via Metals.io and Morpho Protocol.
What remains uncertain
The material supplied for this report does not include xU3O8 price, market cap or trading volume data, and it does not provide any quantified assessment of user adoption, liquidity or loan demand. It also does not establish how closely the token price tracks uranium spot prices at any point in time. The background context warns that a blockchain record alone does not eliminate custody, regulatory or redemption requirements, and that physical delivery remains subject to nuclear-sector regulation.
The source material closes by saying Metals.io has begun broader promotion, including London Underground advertising in October 2026, but no next catalyst with a verified future date is supplied. Timing beyond those cited developments is therefore unknown.
