Frequently Asked Questions for Technical Decision-Makers
Technical and commercial questions we receive from CTOs and engineering leads evaluating our aggregation service.
A standard integration for a new project takes 2-4 weeks from kickoff to production. This includes schema design, smart contract deployment, API integration, and initial credential issuance. For migrating an existing system or building a custom verifier, timelines extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during the discovery phase.
