Question 1

What is xU3O8?

Accepted Answer

xU3O8 is a product that records beneficial co-ownership of physical U₃O₈ (yellowcake) as digital tokens. A token balance represents the holder's share in a pool of physically held uranium under custody, rather than shares, voting rights, or profit-sharing rights in the issuer or operator company. It is implemented as a registered token compatible with ERC-20 and using the ERC-4626 vault standard on Etherlink. The core meaning of holding xU3O8 is a record of beneficial co-ownership of custodial physical uranium, rather than a synthetic token that merely tracks the uranium price.

Question 2

How do xU3O8 tokens correspond to rights in physical uranium?

Accepted Answer

xU3O8 uses a dual-register system to determine shares: the on-chain register records xU3O8 wallet balances and transfers, while another registration layer records the total quantity of physical uranium held in custody. Together, they determine a wallet's beneficial co-ownership share in the entire physical uranium pool. Standard on-chain token transfers update the on-chain register and are reconciled in an off-chain mirrored register. Archax acts both as trustee and as maintainer of the on-chain and off-chain registers; the whitepaper states that it holds smart-contract administrative keys to correct errors or amend on-chain register entries.

Question 3

Who holds the physical uranium in custody, and who maintains the rights register?

Accepted Answer

Physical U₃O₈ is held by Archax in trust for token holders and stored in a storage account at a regulated Canadian uranium processing and storage facility operated by Cameco. Archax is responsible for ensuring that the registers accurately reflect beneficiaries, their shares, and the quantity of uranium held in trust. Accordingly, holders' rights depend on the combined operation of physical custody, the trust arrangement, and the registers; the blockchain balance is part of the rights register, but cannot be understood separately from the custody and registration arrangements.

Question 4

How is xU3O8 issued, and how do day-to-day fees affect holding shares?

Accepted Answer

There are two described paths for additional xU3O8 minting: minting corresponding tokens when additional physical uranium is purchased to meet demand, and minting tokens to collect management fees. The whitepaper explicitly states that additional minting requires additional purchases of physical uranium or must occur under the management-fee mechanism. This means that the number of tokens cannot simply be understood as a permanently fixed quantity of physical units. Day-to-day fees are accounted for through the xU3O8 smart contract; when fees are collected through minting, they affect existing holders' relative shares in the entire physical uranium pool.

Question 5

After holding xU3O8, can I hold it, trade it, or transfer it freely?

Accepted Answer

Holders may hold xU3O8 or sell or exchange it on trading venues where xU3O8 is listed. The Help Center also states that trading can take place on the xU3O8 dApp platform and listed third-party platforms, but specific availability depends on the trading venue and approved wallet. xU3O8 is not a standard ERC-20 that can be freely transferred to any address: it may only be held in wallets at approved trading venues, or in wallets whitelisted for use with the dApp; buying or selling must also take place through a venue able to use that approved wallet.

Question 6

Can xU3O8 be redeemed for, or used to request delivery of, physical uranium?

Accepted Answer

Physical delivery is not an automatic right for all holders. The current Help Center states that holders cannot request physical delivery of U₃O₈ unless they are regulated persons. This restriction reflects the compliance and operational nature of physical uranium: even if tokens are in a wallet, that does not imply an ability to ship uranium to any location or obtain the physical material immediately. Delivery eligibility must be assessed together with applicable regulations and product conditions.

Question 7

Can xU3O8 be used for borrowing?

Accepted Answer

xU3O8 can be used as collateral to borrow USDC on Monarch; this service is supported by Morpho. Being “usable as collateral” here is a specific integration scenario and does not mean that xU3O8 can be used to borrow on every platform, in every region, or from every wallet. The Help Center also states that lending and borrowing functionality for all metals was not supported at that time and remained planned. Therefore, the listed xU3O8 collateral-borrowing use case should be distinguished from functionality that may be expanded in the future.

Question 8

Why cannot xU3O8 rights and value be equated with company shares or a fixed price?

Accepted Answer

xU3O8's value linkage arises from its beneficial co-ownership of a physical uranium pool held in trust, rather than corporate governance rights or profit distributions. Its issue price and trading price are also affected by external physical-uranium price supply, xU3O8 supply and demand, trading-venue liquidity, and transfer restrictions. The whitepaper also warns that the crypto-asset may partly or entirely lose value and may not always be transferable or liquid. Therefore, registration of rights in physical uranium does not guarantee that it can be sold at a particular price, or that it will move one-for-one with uranium market prices.

Question 9

What conditions must be met to purchase and hold xU3O8?

Accepted Answer

After a purchase is completed and applicable compliance checks have been passed, xU3O8 is transferred to the buyer's designated wallet. That wallet must support ERC-20 tokens on the Etherlink network; however, technical compatibility is only a necessary condition and does not replace transfer restrictions involving approved trading venues or whitelisted wallets. In process terms, compliance checks determine whether delivery can be completed, an Etherlink-compatible wallet determines whether the tokens can be managed technically, and whitelisted-wallet or approved-trading-venue rules determine whether subsequent transfers in, transfers out, and trading can occur. The absence of any one of these three conditions may affect asset usability.
