Certificates that inspire trust.
Certifylize connects audit reports, compliance data, serial numbers and digital signatures to a tamper-proof blockchain anchor. Via QR code, PDF fingerprint, API or explorer anyone can verify within seconds whether a certificate is genuine, unchanged and still valid.
No direct download: access is granted via a personal email link.
Signed & tamper-proof
Cryptographic signatures, timestamps and blockchain anchoring on Polygon ensure every modification to a certificate would become visible.
Instantly verifiable
Validation via QR code, PDF upload, API or explorer – typically in under 2 seconds, without any login required.
Enterprise-ready
Versioned audits, role-based approvals, multi-step workflows and GDPR-compliant data storage with EU hosting.
Who is Certifylize for?
Certifylize is built for teams that need to make quality and compliance verifiable – without Excel chaos, scattered PDFs and manual approval chains.
Quality Management & QA
Document inspection reports, scopes, measurements and approvals in a structured and audit-proof way – centrally instead of in isolated files.
Production & Manufacturing
Equip serial numbers, batches and product lines with digital certificates of authenticity – from incoming goods to final delivery.
Purchasing & Supply Chain
Manage supplier certificates centrally, monitor validity and quickly detect suspicious or falsified documentation.
Sales & After-Sales
Customers and partners can verify certificates themselves – simply by scanning the QR code, without login or support tickets.
How Certifylize works – in 4 steps
1. Capture data
Audit reports, measurement data, serial numbers or PDF certificates are captured in Certifylize or imported via API from existing systems.
2. Fingerprint & blockchain anchor
Certifylize generates a cryptographic hash (SHA-256) from the relevant certificate data and anchors it in a smart contract on the blockchain.
3. Certificate & QR code
Based on this data a digital certificate is created, including its own QR code, optional PDF fingerprint and security watermark.
4. Verification in seconds
Customers, auditors or partners scan the QR code or upload the PDF and instantly see whether the certificate is genuine or manipulated – including status information.
Security & Anti-Counterfeiting
Certifylize protects not only the certificate itself but also the entire verification path – from data creation to third-party validation.
Cryptographic fingerprint (SHA-256)
Every certificate version receives a unique fingerprint. Any subsequent modification would change the hash and be immediately visible.
Blockchain anchoring
Hashes are anchored on a public blockchain (e.g. Polygon). Tampering with the anchored data afterwards is practically impossible.
Security watermarks & tokens
QR codes can be protected with additional security layers such as watermarks, context data or tokens to make simple copying much harder.
PDF fingerprint check & audit trail
Optionally, Certifylize checks whether an uploaded PDF exactly matches the stored version – with an audit-proof log of all actions.
Whitepaper: Make trust verifiable
Request the Certifylize whitepaper via email. Access is personalized and time-limited to prevent easy forwarding.
No direct download: access is granted via a personal email link.
Trust & Security
Audit-proof logs, EU hosting, role-based approvals and optional off-chain storage. Certificates anchored on Polygon – exportable as signed PDF or CSV, ideal for audits, OEM requirements and internal compliance.
Easy Integration – API-First
Certifylize is designed as an API-first platform. Certificate issuance and verification can be triggered directly from ERP, QMS or custom applications.
