Anchorage Digital Bank has added custody support for xU3O8, a token representing physical uranium, giving institutional investors access to tokenized uranium through segregated accounts at the first federally chartered crypto bank in the United States.
The move brings physical uranium exposure onto institutional digital-asset custody infrastructure, with xU3O8 issued on Etherlink, an Ethereum Virtual Machine-compatible layer-2 network that settles on the Tezos blockchain.
Anchorage said institutional clients can now custody xU3O8 alongside other Etherlink-based assets. The uranium-specific addition is xU3O8.

xU3O8 represents ownership of physical uranium, allowing investors to gain exposure to the commodity without directly handling or storing the underlying material. CoinMarketCap data puts the token’s market capitalization at just above $9 million at current prices.
According to Anchorage, Uranium has traditionally been difficult for investors to access directly because physical exposure involves
specialist intermediaries,
lengthy settlement cycles, and
relatively high minimum investment sizes.
Tokenization changes the settlement process by putting ownership representation onchain. Anchorage said transactions involving tokenized uranium can be transferred and settled in minutes rather than weeks, potentially reducing the operational friction associated with traditional uranium transactions.

The Anchorage integration is significant for xU3O8 because it adds a federally-chartered banking institution to the custody infrastructure supporting the token. Anchorage said the assets are held through segregated custody accounts allowing institutional clients to maintain tokenized uranium exposure within a bank-based custody framework.
Anchorage is not the first institutional custodian to support xU3O8. Hex Trust integrated Etherlink in August 2025 to provide custody for xU3O8 and other assets issued on the network.
The development also highlights a broader shift in how physical commodities can be represented and transferred digitally.

Instead of requiring investors to interact directly with the physical uranium supply chain, tokenization creates an on-chain representation of ownership while custody arrangements connect that representation to the underlying commodity.
For xU3O8, the immediate institutional question is therefore moving beyond whether uranium can be tokenized to whether regulated custody, liquidity, and settlement infrastructure can make the token usable by professional investors.
Anchorage CEO and Co-Founder, Nathan McCauley, said:
“Institutions are not short on interest in tokenized real-world assets. They are short on places to hold them that satisfy a risk framework.
Adding Etherlink support means an allocator looking at tokenized uranium or onchain dollars can hold those assets at a federally chartered bank, with the same controls they already apply to the rest of their portfolio.”
