Tokenized Commodities Need Proof of Reserves to Shine like Gold

Commodity tokenization grew from about $1.2 billion at the start of 2025 to about $5.5 billion by the end of Q1 2026, roughly four and a half times in 15 months. Tether Gold (XAUT) and Pax Gold (PAXG) produced close to 90% of that growth. Every other commodity divides a small remainder.

The usual explanation for the gap is that buyers don’t want these commodities on-chain yet. Demand exists. Silver gained about 140% in 2025, hit an all-time high above $121 in late January 2026, then fell back and traded roughly $68 to $93 in February and March. Copper is consumed in every EV, solar installation, and data center build. These are large, liquid physical markets with active buyers. That demand has no on-chain market that reflects it yet. Issuer economics and distribution play a part, but credible on-chain versions also need verifiable reserves and a reference price.

Silver is the only metal beyond gold with meaningful on-chain traction. Kinesis Silver, by far the largest silver token, fell in value from $439 million in late January 2026 to $261 million at the end of March, and to $212 million by mid-October. That drop tracks the silver price. The holders stayed: Kinesis held about 3.69 million audited ounces in April 2026, only slightly below the 3.79 million of October 2024. Silver is also the only metal beyond gold carrying a full verification stack: allocated bullion, named custodians, independent audits.

Copper has the stronger long-term demand story and almost nothing on-chain: one token, last valued at about $0.5 million in May 2026, which tracks a copper futures fund rather than holding metal. The demand profiles differ. Industrial use was about 58% of silver demand in 2025, and coin and bar buying grew 14%. Copper demand is almost entirely industrial. Silver followed gold part of the way. Copper has no verification stack.

PAXG sets the bar on reserves. It publishes monthly attestations and holds LBMA London Good Delivery bars. Its issuer, Paxos, has been supervised by the US Office of the Comptroller of the Currency since converting to a federal trust charter in December 2025. Almost nothing outside gold clears that bar. Newer issuers attest periodically or not at all, and half of the 39 tokenized commodity products Tiger Research reviewed in February 2026 remain unregulated. The risks are specific: custodian failure, over-issuance when minting isn’t gated by verified reserves, and tokens that deliver price exposure without an enforceable claim on the underlying metal.

Pricing fails in a similar shape. Gold and silver have deep, continuously quoted spot markets that are straightforward to mirror on-chain. Copper is on the other hand harder. It trades continuously on the LME and COMEX, but that price data is proprietary and licensed. Platinum and palladium lean on twice-daily LBMA benchmark auctions, administered by ICE Benchmark Administration since July 2026, with much thinner liquidity in between. Neither maps cleanly onto a trustless feed. Price oracle coverage follows the same distribution: dense across the majors, thin across everything else.

The dormant end of the market shows that represented value alone does not create a market. Justoken’s tokenized electricity token (JMWH) on the XRP Ledger reports over $2 billion in represented value and about 165 holders. Its tokenized soybean-oil token (JSOY_OIL) on Polygon reports about $440 million with two holders and no transfers in the last month. Trading tells the same story: in the 30 days to 16 October, XAUT and PAXG each traded more than $4 billion, while JMWH did not trade at all and JSOY_OIL has no listing. Without verifiable reserves, credible pricing and liquidity, allocators have little basis to participate.

Regulators are moving in the same direction, though unevenly. Under MiCA, issuers of asset-referenced tokens, the category covering commodity-backed tokens in the EU, must disclose reserve composition at least monthly and commission an independent audit every six months. In the US, the March 2026 joint SEC/CFTC interpretation (Release 33-11412) set out a five-category token taxonomy with no category for tokens backed by physical commodities. Periodic disclosure is the regulatory floor in the EU, the US has none for these tokens yet, and continuous verification is where the market is heading.

Implemented properly, proof of reserve means independent nodes read reserve data at the custodian, reconcile it against on-chain supply, and publish a figure anyone can recompute directly from the contract.

It does not remove trust in the custodian. No oracle can prove a physical bar exists in a vault. What the mechanism changes is the frequency and visibility of the trust boundary: continuously checkable by anyone. Many verification claims in this category name no mechanism, so the boundary is worth stating directly.

The metals that need this layer most are the ones current coverage reaches least. Gold and silver are well served. Copper, platinum and palladium have far less, despite established custody and assay standards behind the physical metal.

DIA runs live feeds for gold, silver and copper, and builds custom feeds for platinum, palladium and other metals on request. DIA publishes its sourcing and methodology for each feed, so an issuer can audit how a price is computed before committing to it.

The reserve side runs the same way. Independent feeder nodes read reserve balances at the custodian, query token supply directly from the contract across every chain the token is deployed on, and publish a ratio, floored conservatively against supply, that any holder can recompute. Nothing in that path depends on the issuer relaying its own number, and it extends to a metals-backed token wherever there is a custodian and audit chain to read from. DIA already runs this live for tGBP, a GBP stablecoin.

Gold already has the trust infrastructure: verifiable reserves and a reference price. The next commodity issuer to build that stack has the best chance to create a real market, and the first to do it sets the reference an allocator later uses to judge every product that follows.
