On April 6, 2026, SMX (NASDAQ: SMX) launched its Digital Material Passport Platform (DMPP), a blockchain-backed system that creates physical-to-digital identities for plastics, metals, and advanced materials using intrinsic material markers.
It is a meaningful addition to the materials-traceability landscape and an early signal of how the Digital Product Passport (DPP) category is taking commercial shape ahead of the EU ESPR registry in mid-2026. Markets respond to clarity, and the past several weeks have brought a great deal of activity to this space.
As the category moves from concept to commerce, a category-level question becomes urgent: what exactly is being verified, and by whom? The answer separates two distinct infrastructure layers that are increasingly collapsed under a single label.
Two layers, often conflated
A Digital Product Passport is a container for claims about a product: where its materials came from, what it is made of, how it was produced, what certifications it carries, and what has happened to it over its lifecycle. The passport itself is structure. The claims inside it come from different sources, and each source requires a different kind of verification.
Material identity is about establishing that a physical object is what it is claimed to be — that this particular batch of recycled polyethylene actually contains the percentage of post-consumer content on the label, or that this gold ingot actually originated from the mine in the declaration. Verifying material identity requires tying a digital record to the physical good, typically through markers (molecular, chemical, isotopic) that can be read back later.
Certificate verification is about establishing that a claim about that material — typically issued by a third-party certification body — is real, current, and issued by the body that purports to have issued it. A GRS certificate, an RJC Chain-of-Custody certificate, a ResponsibleSteel site certification: these are the trust scaffolding of the materials economy. Verifying them requires checking that the certificate record is authentic, unaltered, and still in effect at the moment of the check.
These are different questions with different answers. A system that verifies the material does not thereby verify the certificate, and vice versa.
Why the distinction matters now
EU Regulation 2024/1781 (the ESPR) mandates an open, non-proprietary DPP infrastructure, with the central EU registry expected mid-2026. This is not a stylistic preference. It is an architectural mandate written into Article 9, motivated by the obvious concern that if DPP infrastructure is controlled by individual platform operators, the passports themselves inherit those operators' incentives and fragility.
A proprietary DPP platform can legitimately store material-identity data. But the certifications used as inputs into those passports — recycled content certificates, responsible sourcing certificates, composition claims from accredited bodies — still need to be independently verifiable by any party, at any time, without relying on the platform operator that happens to host them. That is a separate design requirement, and it is where certification bodies themselves have the greatest exposure.
The risk of conflation
If the market begins to treat "DPP platforms" as interchangeable, two things happen. Buyers mistake material-marker systems for certificate verification and discover mid-audit that the certificate behind a claim was never the thing being checked. Certification bodies watch their certificates become inputs into platforms they do not control, with no independent way for downstream users to verify that a certificate is authentic, current, and unchanged. Neither outcome serves the integrity of the certification industry.
The stack, not the winner
The DPP category is not a winner-take-all market. It is a stack. Material identity, certificate verification, passport registry, product-level assembly — each is a distinct function, and each will have its own infrastructure and its own accountable parties. As ESPR, CSRD, the EU Deforestation Regulation, and the FTC Green Guides take force over the next three years, all of these functions will be needed, and regulators will increasingly demand that each one be verifiable on its own terms.
SMX's DMPP addresses material-level identity, and does so with a clear technical approach. IntegraLayer addresses certificate-level verification, as neutral infrastructure that certification bodies themselves control. These are complements, not substitutes. The market will benefit from precision about which layer does which work — and so will every certification claim that has to survive the next decade of regulatory scrutiny.
