SpruceID

Digital trust infrastructure for government services.

We build secure identity solutions that power real-world credential issuance, holding, presentation, and verification — from mobile driver's licenses to professional qualifications. Our open source tools help agencies deliver faster, more secure resident experiences.

Standards

Our implementations help test and refine identity specifications at ISO (18013-5, 18013-7), W3C (Verifiable Credentials), OpenID Foundation (OpenID4VC/VP), and IETF before widespread adoption.

Funding

Some of these libraries were developed with support from the U.S. Department of Homeland Security Science and Technology Directorate (contract 70RSAT24T00000011), building open-source, privacy-preserving digital credential infrastructure for standards-based interoperability across government services.
