One Identity Infrastructure,
All Digital Entities

Flexible cryptographic identity framework serving diverse digital ecosystems

Individuals & Organizations

WebAuthn biometric authentication for humans. Enterprise identity management with institutional governance and compliance controls.

Applications & Services

API authentication and service identity. Integration with existing systems through flexible SDKs and developer-friendly APIs.

AI Agents & Machines

Trust foundation for NANDA registry. Main DIDs for operators with privacy-preserving Associated DIDs for agents, enabling unlinkable yet verifiable credentials.

Built for Project NANDA

The missing identity layer for MIT's Internet of AI Agents vision

Solving NANDA's Core Challenge

Agent Authentication Crisis:

NANDA's AgentFacts need cryptographic identity verification

Privacy vs. Trust:

HyperPlonk proofs link Main DIDs to Associated DIDs without revealing correlations

Registry Extension:

Native AgentFacts schema integration with DID-based identities
