Alcum Review 2026: Copper-Backed Products on Ethereum

Alcum is a Swiss platform, run by ALCUM AG in Zug, that gives eligible investors access to a copper trading business it says has eight years of history. It is listed as a yield vault on Ethereum with a small amount of value locked, but the homepage presents it as a commodity-trading platform rather than a typical DeFi protocol.

There are three products. Cuprum is physical copper stored in your name. Cuprum+ is a loan of your copper to ALCUM, and Cuprum Token is a digital tracker certificate for professional investors.

The homepage shows SRO and VQF badges and names SGS, Accountable and Halborn as verification and audit partners. It also says returns are not fixed or guaranteed and that access depends on identity checks, eligibility and location.

Alcum runs a copper trading business. According to its homepage, it buys scrap copper, refines it and sells it, with trades typically taking 2 to 6 weeks. It then offers outside investors three ways to take part, each with different rights.

With Cuprum, you buy physical copper that is set aside in your name, and its value moves with the copper price. With Cuprum+, you lend copper to ALCUM, which uses it in trading and credits positive monthly results as extra copper. With Cuprum Token, you hold a certificate whose return tracks the net results of the trading cycles.

The on-chain part is small. The listing shows Ethereum as the chain and a modest amount of value locked, and the homepage mentions smart contracts audited by Halborn and checks that on-chain records match documents. The copper, warehouses and trades themselves are off-chain.

Alcum's homepage does not publish a fee schedule. It says that full fees, protections, redemption mechanics and settlement terms are set out in the documentation for each product.

For Cuprum Token, it says returns come from net trading results after costs and fees. Check the product documents before committing capital to see how costs are charged.

Alcum states that stored copper is inspected by SGS, that Accountable checks documents against on-chain records and that Halborn audited the smart contracts. It also mentions insurance, controlled payment accounts, hedging where a product is designed for it and enforcement rights for Cuprum Token investors held outside ALCUM. The homepage shows SRO and VQF badges, but the exact regulatory status of each product is not spelled out there.

The main risk is counterparty risk. Cuprum+ holders are unsecured creditors of ALCUM AG, and returns for the token depend on trading results. Copper price moves, execution, settlement timing and legal risks specific to each product also apply. These safeguards reduce risk but cannot remove it, and this is not financial advice.

Alcum is for investors who want commodity exposure to copper and accept KYC/KYB checks. Cuprum Token is only for professional investors, so smaller or retail users would look at Cuprum or Cuprum+ if available in their location. It is not for people seeking guaranteed yield or fully on-chain, permissionless DeFi.
