END-TO-END EXECUTION
Our Development and Integration Process
A structured, transparent workflow designed for technical leaders. We deliver production-ready product passports with clear milestones, from initial design to on-chain deployment and ongoing management.
01
1. Strategy & Protocol Design
We define your passport's data schema, tokenomics, and governance model. This includes selecting the optimal base standard (ERC-1155, ERC-721, or custom) and designing the on-chain/off-chain data architecture for verifiable provenance.

Digital Product Passport Development FAQs
Get clear answers on timelines, costs, and technical implementation for your circular economy product passport project.
A standard Digital Product Passport (DPP) deployment takes 4-6 weeks from kickoff to production. This includes requirements analysis, smart contract development, frontend integration, and on-chain deployment. Complex integrations with existing ERP/PLM systems or multi-chain architectures can extend this to 8-10 weeks. We provide a detailed week-by-week project plan during the discovery phase.
