xU3O8 (uranium.io)

Research and shelf status are on the memo: xU3O8 uranium token (uranium.io) Adverse research finding

Who may buy, hold, transfer, and redeem

Each answer rests on the issuer’s own words, quoted from the document named under it. Ketju re-reads each document and records whether the words are still there. Where the documents say nothing, the row says so.

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 may hold it

Anyone who passes wallet screening for sanctions and illicit activity; uranium.io lists no excluded countries or US states.

“Being a spot commodity, there are no geographical access limits other than based on AML/CFT and/or sanctions screening.”

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

A wallet that screening flags is frozen until the holder clears enhanced due diligence, and stays frozen if it 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 can change the record

Powers read from the deployed contracts and their verified source: the token and every contract it consults on transfer. A power recorded here is the issuer’s ability, not evidence it has been used.

Who holds the keys

Every current holder of each power, read from the chain on 2026-09-23. A single key is one private key: whoever holds it acts alone. A multisig needs the stated number of signers. A timelock makes every action wait, so holders can see it coming.

What the monitor reads daily

Every control function in the table above and the contracts the token consults on transfer; the token’s on-chain supply against yesterday’s; and its market quote against yesterday’s quote. Every document quoted above is re-read too, and a quote that leaves its document reopens the file. A change opens a review item in the governance queue and reopens the file before any client action.
