Eligibility
Each answer quotes the issuer’s own words from the document named under it. Ketju reads each document again and records whether the words are still there. Where the documents say nothing, the row states that.
- What the holder owns
A unit of beneficial ownership in a pool of U3O8 that Archax Ltd holds on trust for token holders.
“Each xU3O8 represents a unit of ownership of U3O8 held by Archax as a custodian for investors.”

- Who it may be transferred to
The white paper says only wallets of approved venues or wallets whitelisted in the uranium.io app can acquire the token. On 2026-09-23 the contract’s KYC switch was off, so any wallet not on the blacklist could receive it.
“Only wallets of approved trading venues (CEX) or whitelisted for use in the dApp can be used to acquire xU3O8.”

- How a holder redeems
Only a holder regulated by a national nuclear regulator, with an account at a licensed facility, can take the uranium, by book-entry transfer; everyone else sells.
“Unless you are a regulated person, you cannot request physical delivery of U3O8.”

- Who keeps the official record
The token contract is the register of beneficial ownership; Archax, as registrar, also keeps an off-chain mirror and holds keys that can amend the on-chain entries.
“The beneficial ownership records are maintained by way of a Tezos based smart contract (named: xU3O8).”

- What the issuer says it can freeze or take back
uranium.io freezes a wallet that screening flags until the holder clears enhanced due diligence, and keeps it frozen if the holder fails. On chain, one address can blacklist, pause, and burn any balance.
“If a Redlight status applies to a Wallet it shall become the subject of a compliance freeze”

Who controls it
Ketju read these powers from the deployed contracts and their verified source code: the token and every contract it checks on a transfer. A power listed here is something the issuer can do; it does not mean the issuer has used it.
| Chain | Freeze a holder | Pause | Claw back | Gate holders | Change the code | Keys held by |
|---|---|---|---|---|---|---|
| Etherlink | Yes | Yes | Yes | Yes | Yes | A single key can freeze a holder and pause transfers and claw back tokens. A single key can change the code with no delay. |
Who holds the keys
Ketju read every current holder of each power from the chain on 2026-09-24. A single key is one private key, and whoever holds it acts alone. A multisig needs the stated number of signers. A timelock delays every action, so holders can see it before it takes effect.
| Chain | Key | What it can do | Held by | Address |
|---|---|---|---|---|
| Etherlink | Admin role | grant and revoke these powers, freeze a holder, decide who may hold | a single key | 0x0400…c807 |
| Etherlink | Pauser role | pause transfers | a single key | 0x0400…c807 |
| Etherlink | Minter role | mint new tokens | a single key | 0x0400…c807 |

Where it trades
| Venue | Kind |
|---|---|
| uranium.io exchange interface on Etherlink (USDC pair), with wallet screening by Provenance Ltd | dex |
| Kraken (Payward Global Solutions Limited), named in the MiCAR white paper | exchange |
Redemption
| Route | Settlement | Settles in |
|---|---|---|
| Redeem in kind | A holder with an account at a regulated uranium conversion or storage facility may ask for a book-entry transfer of the U3O8 behind its tokens to that account. uranium.io says physical delivery to anyone else is not feasible. The white paper makes redemption conditional on access to a compliant facility and the ability to transport the material. uranium.io publishes no minimum, fee, or timetable. | U3O8 (book-entry transfer between licensed facility accounts) |
| Secondary market only; no issuer redemption | Everyone else can only sell: on the uranium.io exchange interface against USDC on Etherlink, or on a centralized exchange that lists the token (the MiCAR white paper names Kraken). There is no peg to the spot price and no issuer buyback. | USDC, USD |
- The implementation behind the Etherlink proxy changes, or the admin, minter, pauser, wiper, or upgrader role leaves or joins 0x04009bc730862953bf06bf445f24b2f8bbe5c807
- The KYC switch on the token is turned on, which would limit every transfer to approved wallets
- A wipe burns a holder’s tokens, or the blacklist grows sharply beyond the 159 addresses listed on 2026-09-23
- Total supply moves from 1,600,000 without a matching change in the Cameco statement, or the administration fee is first collected by minting to the treasury
- A monthly Cameco statement is missed, shows less uranium, or the storage account changes hands
- Archax resigns as trustee, the deed of trust is published or amended, or uranium.io completes its move to Metals.io under new terms
Daily checks
Every day Ketju reads each control function in the table above and the contracts the token checks on a transfer. Ketju compares the token’s on-chain supply with yesterday’s, and its market quote with yesterday’s quote. Ketju also reads every document quoted above and reviews the file again if a quoted passage disappears from its document. Ketju counts a new, removed, or changed key as a change only when the chain’s own log shows the grant, revocation, or signer change since yesterday. If the log does not show it, Ketju updates the key list in this file and does nothing more. A change opens a review before any client action. Subscribers get an email that names each of their clients who hold the token, with the household result.
