DPP Ledger, developed by CollabTrace, is a modular platform compliant with European regulations that allows companies to create durable, secure digital product passports fully under their control.
With DPP Ledger, you own your product data like never before.
Your data. Your infrastructure. Your rules.
Your compliant, distributed, and controlled digital product passport.
DPP Ledger, developed by CollabTrace, is a platform for creating, managing, and querying digital product passports compliant with the European ESPR Regulation and major international standards such as EN 18222, EN 18219, and ISO/IEC 15459.
All information contained in the DPP belongs 100% to the company that generates it. The company decides what is published, protected, and who can access it. No dependency on third parties or data lock-in.
No dependency on third parties or data lock-in.DPP Ledger is built as a modular system, extensible via regulatory and technical plugins such as: GS1 (GTIN, Digital Link, SGTIN, GRAI, etc.), DID and Verifiable Credentials (W3C), CEN and related ISO standards, and future support for new regulatory or industrial frameworks.
Thanks to the use of standardized identifiers (ISO/IEC 15459-4 and 15459-6), each product has a globally unique digital identity.
Passports are stored on the blockchain with multi-chain compatibility: Ethereum, Base, Solana, and others, ensuring long-term persistence and availability.
Sustainability, traceability, maintenance, origin, certifications, composition, usage, and more: all relevant information centralized and signed.
The DPP can be accessed via a web link, scanned with a smartphone, or integrated into platforms via standard APIs.
Decentralized infrastructure with enterprise protection.
Integrity and permanence guaranteed (Ethereum, Base, Solana, etc.)
Protection against the future
Protects know-how and processes
Compliant with EN 18222
Let each product answer for itself.
Each DPP generated in DPP Ledger includes an Artificial Intelligence Agent that allows any user to interact with the product using natural language.
Technical documentation, certificates, maintenance history, sustainability data, and more.
Large volumes of structured and unstructured information quickly, clearly, and contextually.
About product attributes, usage instructions, legal or regulatory requirements, according to the user's profile.
A DPP can have children, and know where each part comes from.
With DPP Ledger you can build composite products with complete traceability:
