Uranium.io Review: Is XU3O8 Worth Considering?
Uranium.io offers tokenised fractional ownership of physical uranium through XU3O8, but fees and key safeguards are not fully disclosed. Its announced move toward Metals.io makes it especially important to confirm that uranium buying and trading are still supported before you sign up.
By the SkyBitcoins review team · Updated
Quick take
Uranium.io may suit crypto users seeking fractional exposure to physical uranium through XU3O8, rather than buying shares in uranium companies. Its main appeal is the stated link to uranium held in custody, with USDC funding and no advertised minimum purchase. Before depositing, verify that the uranium service is still available during its move toward Metals.io, and get the custody, administration and exit terms in writing.

Who Uranium.io suits
Good for
- Investors seeking fractional exposure to physical uranium rather than a mining-company share
- Crypto users comfortable holding a token tied to an off-chain commodity and custody arrangement
- People who want to explore uranium exposure and can verify current fees, availability and exit options
Not for

- People who require an audited smart contract or independently documented protections
- Investors who want direct delivery or clearly explained redemption rights for physical uranium
- Anyone who cannot confirm that Uranium.io still supports XU3O8 purchases and trading
What do you actually own when you buy XU3O8?
Uranium.io is a real-world-asset project built around XU3O8, a token intended to represent fractional beneficial ownership of physical uranium ore concentrate, commonly called yellowcake. The project says the uranium is held in a custody account and that the token acts as a smart-contract ownership ledger. This is different from holding uranium in your own possession, and it is not the same as buying shares in a uranium miner.
The stated route is to create an account, add USDC and buy XU3O8. Uranium.io advertises no minimum purchase amount and says the token can trade around the clock on exchanges that list it. Those claims do not establish that every exchange has active liquidity or that you can always sell at a fair price. The homepage also says the project is evolving into Metals.io. Confirm that buying and trading XU3O8 remain available, and understand what the change means for existing holders, before committing funds.
What will buying and holding uranium cost you?
Uranium.io says it does not charge an asset-management fee, but that custody and administration fees apply. It does not publish their rates on the homepage, so you cannot calculate the ongoing cost from the headline claim alone. Ask for the current fee schedule, how often fees are charged, and whether fees are deducted in cash, USDC or from your uranium holding.
You may also face costs outside the platform’s stated fees. Buying or selling on an exchange can involve trading fees and a spread between buy and sell prices; moving tokens can incur network fees. Converting another asset into USDC may add a further cost. These expenses depend on the route you use, so check them before sending funds.
The project advertises no minimum purchase amount, but that does not mean a small holding is cost-free or easy to sell. Compare the total costs with the amount you plan to invest, and check whether there is enough trading activity to exit when you want.
How much protection does the custody arrangement give you?
The project describes XU3O8 as evidence of beneficial ownership in physical uranium held by Archax as custodian, in a dedicated custody account at a regulated depository. That arrangement gives the token a stated connection to an off-chain asset, but you still depend on the custodian, the legal structure and the records that link tokens to uranium. It does not mean uranium is held in your personal custody or that you can take delivery whenever you choose.
No audits are listed, and the homepage does not establish the issuer’s licence, the details of any regulatory authorisation, or what recourse holders have if a service provider fails. It also does not explain redemption rights or the full legal process for enforcing ownership. Treat these as material questions, not minor paperwork. Read the current terms and custody documentation before buying, and do not treat the word “regulated” as proof that every part of the product is regulated or protected.
The announced move toward Metals.io adds another reason to check which company and terms apply to your holding today.
How can you start without making an avoidable mistake?
The advertised onboarding is straightforward in outline: sign up, add USDC, then buy uranium. Uranium.io provides a guide for obtaining USDC, but does not publish a detailed account of supported payment methods, processing times, withdrawal limits or identity-check requirements on the homepage. Check those details for your location before you fund an account. Do not assume that sign-up means you can withdraw or trade without checks.
The project’s token information refers to Tezos technology, while the project classification identifies Etherlink. Confirm the current network and the exact deposit and withdrawal instructions in your account before moving tokens; sending an asset on the wrong network can cause a loss. The homepage also refers to trading on exchanges that list XU3O8, but does not name them there. Verify that an exchange supports the exact token and network, and check liquidity and withdrawal support before relying on it as an exit route.
Because the product is evolving into Metals.io, confirm the live onboarding flow and terms directly before transferring USDC.
What should make you pause before investing?
This product is not a simple, fully transparent way to hold physical uranium. The custody and administration charges are not priced publicly on the homepage, no audits are listed, and the issuer’s licensing and detailed holder protections are not established there. The project also does not explain how a token holder can redeem for physical uranium, if redemption is available at all. You should get clear answers on these points before investing.
Uranium itself can be volatile. The project identifies policy changes, trade restrictions and geopolitical events in uranium-producing regions as factors that can affect prices. Its promotional performance comparison is historical and explicitly warns that past returns are not a reliable indicator of future results. Do not use that comparison as a forecast.
Finally, the stated transition to Metals.io means the service may change. If you need a stable operating model, published costs, independent audits or a defined physical redemption route, choose a product that documents those features clearly instead.
