ENTERPRISE-READY IDENTITY INFRASTRUCTURE
Core DID & Verifiable Credential Capabilities
We deliver the foundational components for secure, scalable, and interoperable decentralized identity. Our services are built on battle-tested standards, ensuring compliance, privacy, and seamless integration into your existing systems.
01
DID Method Implementation
Custom development and integration of W3C-compliant DID methods (e.g., did:ethr, did:key, did:web) for your specific blockchain or ledger. We ensure your identifiers are globally resolvable, cryptographically verifiable, and fully under your user's control.

Technical and Commercial Considerations
DID Implementation: Common Questions
Answers to the most frequent questions from CTOs and product leads evaluating decentralized identity solutions.
Standard DID system deployment takes 2-4 weeks from kickoff to production. This includes architecture design, smart contract development, integration with your existing auth stack, and security audit preparation. Complex enterprise integrations with multiple legacy systems or custom credential schemas may extend to 6-8 weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
