Battery Passport mandatory: February 2027
Electronics, textiles, and construction follow. Across sectors and jurisdictions, the same threshold is converging: content must be authentic, attributable to a named legal entity, and verifiable long after it is challenged.
Don't mistake data for evidence.
Who stood behind the exact content, when, and has it changed?
Cryptar is the trust and control layer that enables non-repudiation and legally accepted immutability across existing systems, organisations, and jurisdictions, without requiring jointly trusted infrastructure.
Qualified evidence
eIDAS Art. 35(2) legal force
PKI-first, composable trust anchors
qSeal, blockchain, TSA or any combination. No shared ledger required.
Data stays in your environment
Only cryptographic proof travels. Your dataset never leaves your environment.
Portable proof
Verifiable long after any challenge, on any platform
Proof chain overview
End-to-end verification pipeline
Connect
Integrate via API with existing systems, supplier workflows, and data platforms. No rearchitecting required.
Capture
Record the exact content state of every declaration, DPP entry, or certificate. Issuer identity and timestamp locked in.
Version
Corrections link explicitly to the prior state. Current, superseded, and historical versions remain distinguishable.
Seal
Apply qualified electronic seals at publication events and regulatory submissions, creating the eIDAS Art. 35(2) legal presumption of integrity.
Verify
Evidence travels with the document or data record. Each party verifies against their relevant trust anchor, without platform access.
Built for established trust and industrial ecosystems
Certified trust services, regulatory standards, and innovation network partnerships form the foundation of Cryptar's enterprise-grade verification layer.
QTSP
Swisscom Trust Services is the primary qualified backend, certified under eIDAS and ETSI EN 319 standards. Comparable accredited QTSPs are supported across jurisdictions where equivalent frameworks apply.
Standards
Designed for ESPR/DPP requirements (prEN 18239, prEN 18246/ESDC) and eIDAS Art. 35(2). Co-author of the Plattform Industrie 4.0 publication "Pathway to Becoming a Digital Champion".
Industry recognition
AiF InnovatorsNet member, connecting innovative SMEs with applied research institutions across sectors driving digital transformation and industrial innovation.
Compliance requires data. Accountability requires evidence.
Regulatory requirement met. Content accountability still open.
Regulatory submissions create records, not defensible evidence. When content is challenged, the question is not whether data exists but whether it can be attributed to a named legal entity, with a verified timestamp and version history.
Regulated filings, supplier qualification, product certification
In each case the exact content must be attributable and non-repudiable, not just present. Submission alone does not satisfy non-repudiation.
Supplier claims the data. You carry the dispute.
When third-party data is challenged, the burden of proof typically falls on the party holding the system of record. Qualified seals under eIDAS Art. 35(2) shift that burden to the challenger.
Which version was authoritative at audit?
Version disputes stall when responsibility for a specific data state is unclear. A cryptographic version chain with explicit attribution delivers precise lineage on demand.
Identity, traceability, and data management solutions each do their job. Cryptar connects them with qualified trust services into a single portable evidence chain.
A qualified seal is essential. Cryptar makes it work.
A qualified seal under eIDAS or an equivalent accredited framework delivers the legal presumption of integrity and origin. Cryptar makes that presumption operational: across versions, infrastructure, and the physical world.
Version & currency
A seal proves a moment in time but not whether a newer version exists. Cryptar's version chain makes currency explicit and provable on demand, including qualified proof of withdrawal so revocation carries the same legal weight as issuance.
Scale & economics
Local x.509 signatures across an organisation's infrastructure consolidate into a single qSeal or equivalent qualified seal at configurable intervals. One seal establishes qualified nonrepudiation for everything inside it.
The print break
A digital seal does not survive printing. Cryptar embeds verification information and the trust anchor in a QR code or metadata. Scanning a printout still returns the current version status and cryptographic proof of the seal.
Three entry points. One trust architecture.
Three entry points for different needs and deployment scenarios, built on the same underlying trust protocol.
Sealed document
Every issued document carries verifiable proof of current version, correction history, and issuer identity via QR code. Printouts remain fully verifiable. Extend to qSeal or equivalent where recipients or regulators require it.
Custom local audit trail
Legally accepted immutability for documents and data records, integrated into existing systems via API or SDK. No multi-party setup required.
Multi-party evidence chain
DPP entries, supplier declarations, test reports, updates, and update receipts connected into a full evidence chain. Clear accountability in cooperation: each contribution attributed and sealed under the contributing party's legal entity identity.
Who this is for
Manufacturers & brands
Enter audits with a defensible, versioned evidence record. Reduce audit response time and eliminate version disputes.
Compliance, legal & audit teams
Portable evidence that holds up in regulatory inquiries without manual reconciliation. Qualified seals shift the burden of proof to the challenger.
Official bodies & legal professionals
Issue sealed documents with independently verifiable proof of issuer identity, content state, and date. Recipients verify without platform access.
DPP platforms & system integrators
Add qualified non-repudiation to existing solutions via API. Extends to any platform that needs content-level proof at scale.
See how it works in five minutes.
The demo uses a digital EU Declaration of Conformity, a document CE-marked manufacturers are now digitalizing under EU product regulation. It shows a document issued and sealed, a correction versioned and linked to the original, and a recipient's outdated printout flagged on QR scan with cryptographic proof of the timeline. No platform login required to verify.
EU DoC issued and sealed: no change to existing systems
Correction applied: new version linked to prior, timeline explicit
Recipient's outdated printout flagged on QR scan: version chain shown
Independent verification: cryptographic proof without platform access
Build the compliance record that holds up when it matters.

Bring your stack and compliance context: DPP data, supplier declarations, regulated filings, or any accountability requirement where content provenance needs to be defensible.
