From uranium to rare earths: Tezos’ bid to tokenize the elements

At TezDev 2026, Arthur Breitman reiterated his longstanding belief that crypto’s next frontier is tokenized commodities, unveiling uranium and metals tokens as the start of a broader ‘periodic‑table roadmap’.

What if the future of on-chain science were built directly on the periodic table, with each element not just a chemical symbol but a programmable asset, a collateral primitive, and a market in its own right?

If every element is a programmable asset, then the periodic table stops being a chart in a lab and becomes the primitive layer for on‑chain markets, governance, and even scientific experimentation. The open question is whether crypto is ready for that level of physical entanglement, or if it is still more comfortable trading abstractions than rebuilding the world’s material ledger from hydrogen up.

Tezos’ Breitman wants to bring the periodic table on-chain

At TezDev 2026, held during ETHCC in Cannes last week, Tezos co‑founder Arthur Breitman told an audience of onlookers that his thesis re: the next frontier for crypto isn’t gaming or NFTs, nor even just commodities, but rather the entire periodic table itself.

“Commodities are super interesting because the regulatory status of spot commodities in most countries is much more amendable I would say to work on a blockchain than it is for securities,” he said, drawing a clear distinction between speculative crypto assets and the physical underpinnings of industrial economies.

Breitman’s comments framed the launch of Uranium.io and Metals.io as the first coordinated attempt to tokenize the periodic table — beginning with uranium, gold, and strategic base metals. “Base metals I think are really interesting. So things like cobalt, cadmium, some precious metals as well. I think there’s still some interest here. Copper, lithium, all of that. There’s an interesting play here,” he told the audience, arguing that on‑chain representations of real commodities could evolve into a programmable collateral layer for global markets.

From uranium to rare earths

The flagship uranium token, xU3O8, represents physical yellowcake held in custody and traded 24/7. “Now that it’s tokenized on Etherlink, on top of that perhaps when there’s more liquidity you can imagine perps which is a nice innovation from the DeFi world,” Breitman added, naming uranium as the first element in a wider pipeline of commodities expected to follow.

He connected this to a foundational principle: “There’s an opportunity to create something that doesn’t exist as opposed to trying to replace other systems and there’s a better fit in terms of the technology and the regulatory climate.” Rather than retrofit blockchain to equities or bonds, Breitman’s vision builds markets where none previously existed — in his words, for “long‑tail commodity markets which are underdeveloped.”

Among so-called real-world assets, commodities have traditionally not been seen as the best tokenize, until now. Hyperliquid, with its 24/7 commodities perp trading, turns “outcomes” and commodity exposures into standardized on‑chain contracts that trade 24/7 instead of on banker’s hours. As Bloomberg noted, Hyperliquid’s commodity perpetuals have become a venue for off‑hours hedging in gold and oil, suggesting that once the rails exist, long‑tail commodities don’t just list — they light up with liquidity in the gaps where traditional venues are still dark.

Hyperliquid, Uranium.io, and what Tezos is building are pointed at the same target—on‑chain commodities—but they are attacking it from almost opposite ends of the stack. Hyperliquid is first and foremost a trading machine: it abstracts real‑world underlyings into standardized, cash‑settled instruments and lets users lever up on 24/7 perpetual exposure, with no necessary pretense that any given position is redeemable for a drum of oil or a drum of uranium.

By contrast, Uranium.io and Metals.io are trying to start from the barrel, not the chart: custody first, legal title first, then tokenize that claim and only later plug it into perps, lending, or structured products.

That makes Hyperliquid a venue for price discovery and speculation on top of “commodities as a data feed,” while the Tezos approach wants the token to be the legally enforceable wrapper around the underlying metal itself.

That market intuition, Breitman said, is not lost on veterans of physical trading. “A lot of the people I know that got really early into Bitcoin — I meanback in 2012 — were people who were commodity traders. Commodity traders understand supply and demand,” Breitman noted during a later panel.

A roadmap built from elements

Bem Elvidge, Head of Commercial Applications at Trilitech, echoed Breitman’s push: “the periodic table… is actually going to be our product roadmap,” he added. What began with uranium and gold will not be expanding into alloys, rare‑earth oxides, and other verifiable assets intrinsic to the modern industrial base, Elvridge and Breitman said.

For Breitman and those building on Tezos, the promise is straightforward but profound: to bring real‑world metals — tradable, divisible, liquid — onto open ledgers.

But the unresolved tension is whether the future belongs to exchanges that treat commodities as continuous, model‑driven payoff streams, or to asset rails that insist every token maps cleanly back to a warehouse, a regulator, and a stack of shipping documents.

Moreover, even as real‑world assets march on‑chain, the industry still has not answered who actually bears the risk when volatile spot markets collide with immutable code and fragmented regulation. If the periodic table is the roadmap, the unresolved question is whether tokenization is genuinely re‑wiring commodity finance or just rebuilding the same concentrated, opaque structures on a faster settlement rail.
