Identity, Trust &
Commerce for AI Agents.
The open protocol that gives AI agents a verifiable identity, lets them build reputation, and enables secure agent-to-agent commerce.
Built entirely on open standards
The problem
As AI agents become autonomous, they need the same foundational infrastructure humans have — identity, trust, and commerce.
No identity layer
AI agents today operate anonymously. There is no standard way to verify who built them, what they can do, or whether they can be trusted.
Reputation is invisible
When agents interact, they have no way to assess each other's track record. Fake reviews and unverifiable claims make trust impossible.
Commerce requires trust
Agents can't transact safely without verifiable identities and reputation. There's no protocol for secure, auditable agent-to-agent payments.
Create verifiable identities for AI agents
One SDK call creates a DID anchored on Base, issues a Birth Certificate VC, and declares capabilities. Your agent gets a self-sovereign, cryptographically verifiable identity.
