Metals.io issues 25,000 xCu copper tokens backed by metal stored in Hamburg
In brief
- Metals.io issued 25,000 xCu tokens, each tied to one kilogram of refined copper.
- A Hamburg warehouse holds the first 25-tonne batch, according to Crypto Briefing.
- xCu runs on Etherlink, an application built on Tezos, so it trades around the clock.
- Archax is named as custody and compliance partner in Metals.io's stated setup.
- Metals.io hopes to scale copper to millions of dollars, depending on investor demand.
How the structure works
Ownership is recorded on the blockchain as beneficial ownership. Token holders hold the economic claim, and a custodian keeps the physical metal. Metals.io named Archax as its custody and compliance partner, and the company says the setup is designed so the copper isn't rehypothecated (that's Metals.io's stated arrangement, not something an outside party has verified). Research findings on the launch say the platform uses bonded warehouses in the Netherlands and Germany. This first batch is in Hamburg.
The retail pitch is simple. Metals.io advertises no minimum purchase and no asset management fees, and holders can redeem tokens for physical copper if they meet certain requirements. The company's launch materials call xCu the first physically backed, spot-price copper investment product aimed at retail investors.
Crypto Briefing called it a deliberate test run for a company that wants to bring copper exposure to people who've never set foot on a trading floor.
Sixth metal on the shelf
Copper isn't the company's first commodity. Metals.io had already tokenized uranium, gold, cobalt and nickel. With xCu added, it now lists six products: xU3O8 (uranium), VNXAU (gold), xCo (cobalt), xNi (nickel), RARE (a strategic metals basket) and xCu (copper).
The demand case rests on forecasts cited in the launch research. Those forecasts point to a 50% increase in copper demand by 2040, driven largely by electric vehicles, renewable energy, AI data centers and electrification. The same research says a single large AI data center could require up to 50,000 tonnes of copper. It also projects that data-center copper demand overall will reach 1.1 million tonnes a year by 2030.
What holders are trusting
Metals.io hopes to grow its copper offering to millions of dollars over the next year. That depends on investor demand.
The bigger question is trust, not the token. Holders depend on custodians, warehouse operators and legal structures doing what they say they'll do. A blockchain record can prove who owns a token, but it can't independently inspect the warehouse.
