A supplier statement held on the supplier's own server is not evidence. ProntoID binds a declaration to a verified legal entity and a product identifier, then seals it — so it is clear who said what, about which product, and exactly when.
Overstating this would make the product useless. The boundary is stated plainly, because the boundary is what makes the attestation reliable.
Assessment of product claims remains with accredited certification bodies, inspection bodies and competent authorities. ProntoID performs no product certification.
Before any statement can be sealed, the legal entity is verified through ProntoID KYB and a named individual is bound to it as an authorised signer. An unverified declarant produces no attestation.
The declaration is attached to a product identifier — a GTIN, and where relevant a batch or lot number — so the statement refers to an unambiguous, resolvable subject rather than to a product name.
Certificates, analysis reports and supplier declarations are referenced in the record by SHA-256 digest. The record therefore points to exact bytes, and a substituted document no longer matches.
The payload is serialised deterministically under RFC 8785 and a detached JWS is produced using an ECDSA P-256 key held in AWS KMS. The sealed instrument is written to an append-only ledger.
The sealed record is exposed at a stable resolver address, so it can be surfaced from an existing product page, a GS1 Digital Link QR code, or a buyer's own due-diligence system.
The entire value of a sealed declaration rests on knowing who made it. Business verification is not an optional add-on here — it is the foundation.
See ProntoID KYBThe mechanism is identical in both cases. The evidential weight is not.
The manufacturer or supplier makes the statement themselves. The value is non-repudiation and dating: they cannot later claim they never said it, never said it in those terms, or said it at a different time. Useful for supplier declarations flowing to a buyer who needs a defensible record of what they were told.
The declarant is an accredited certification or inspection body, a consortium, or another independent authority. The attestation then carries that body's assessment rather than a self-declaration — a materially stronger claim. ProntoID's role is unchanged: it seals what the body stated and certifies nothing itself.
ProntoID does not ask you to add a second barcode, adopt a new consumer app, or migrate your product content anywhere. Declarations are bound to the identifiers you already use.
Where a GS1 Digital Link QR code and a product information page already exist, a sealed declaration resolves alongside them. Where a buyer's procurement system needs the record directly, it resolves there instead.
Illustrative structure. Exact schema is agreed during integration.
You carry due-diligence exposure for claims your suppliers make. A sealed declaration is a defensible record of exactly what you were told and when you were told it.
Anti-counterfeiting programmes hold genuinely valuable attestations. Sealing releases them from unstructured documents into a form buyers and systems can actually check.
Your assessments currently end their life as a PDF. Sealed attestations bound to a product identifier make them resolvable, machine-readable and tamper-evident.
Where a claim is central to positioning, a sealed and dated declaration is meaningfully harder to imitate than a marketing badge anyone can print.
Require sealed declarations from sellers making regulated or high-risk product claims, and retain evidence of what each seller declared at listing time.
Replace a folder of supplier PDFs with a verifiable chain of who declared what, when, and against which supporting evidence.
It is a statement about a product — its origin, composition, certification status or any other declared attribute — made by a legal entity that ProntoID has verified, bound to a product identifier, and cryptographically sealed. The seal makes the declaration non-repudiable: the declarant cannot later deny having made it, and the wording cannot be altered without detection.
No, and this distinction is deliberate. ProntoID verifies the identity of the declarant and seals the exact statement they made, at a recorded point in time. ProntoID does not inspect products, audit facilities or certify claims. Assessment of the underlying claim remains with accredited certification bodies, inspectors and competent authorities.
It proves four things: which verified legal entity made the statement, which named and identity-verified individual signed it, exactly what was stated down to the byte, and when. Those four facts together make a declaration usable as evidence, which a self-hosted PDF on a supplier website is not.
Yes, and that is the stronger configuration. Where the declarant is an accredited control body, a consortium or an inspection body, the sealed attestation carries the weight of that body's assessment rather than a producer's self-declaration. ProntoID's role is unchanged: it seals what the accredited body stated, and takes on no certification role of its own.
ProntoID sits behind the identifier rather than replacing it. A declaration is bound to a GTIN and, where relevant, a batch or lot number. Existing GS1 Digital Link QR codes and product information pages can resolve a sealed declaration alongside the content they already serve, so no separate scanning journey is required.
Nothing is ever overwritten. A correction is issued as a new sealed instrument that references the digest of the record it supersedes. The ledger therefore preserves both what was declared originally and what replaced it, along with the dates of each — which is precisely what makes the history defensible.
Primarily for organisations that carry due-diligence exposure for statements made by others: retailers, importers, brand owners and platforms who need a defensible record of what a supplier declared. It is also used by consortia and certification bodies that hold valuable attestations currently trapped in unstructured documents.
No. Statutory labelling and information obligations are set by law and are unaffected. A sealed declaration is a supplementary evidentiary layer designed to support due-diligence and traceability processes; it is not a substitute for any mandatory disclosure, certification or inspection regime.
