AI agents are growing fast. They talk to users, execute actions, coordinate with other systems, and increasingly make decisions that matter. Yet most of them still operate without a real identity. They appear as anonymous software, disconnected from the humans and organizations that created them.
This lack of identity creates a trust gap. When an AI agent behaves incorrectly, there is no clear way to understand who built it, who controls it, or whether it can be trusted at all. As AI adoption grows across business, finance, and public systems, this gap becomes a real risk, not just a technical limitation.
Know Your Agent or KYA is a system that gives AI agents a verifiable identity, ties them to their creators, and lets trust and reputation grow in public.
It is built on Deep Trust, our framework designed to give AI agents verifiable identity, clear ownership, and composable reputation, while preserving privacy and decentralization at scale.
Trust in AI is often discussed in terms of models, data, or outcomes.
But all of these assume something more basic. That an AI agent can be identified in a reliable and verifiable way.
Without identity, accountability breaks down. An agent can make claims, but no one can verify who stands behind them. Reputation cannot accumulate, because there is nothing stable to attach it to. Governance becomes impossible, because responsibility cannot be traced.
For businesses and builders, this creates friction. For users, it creates uncertainty. For the internet as a whole, it creates a huge risk.
DeepTrust starts from a simple idea. If AI agents are going to act in the world, they need identities that can be verified, linked to humans, and trusted over time.
Watch how Billions, the privacy-first verification network for humans and AI, brings Know Your Agent into its tech stack:
At a high level, Know Your Agent connects AI agents, humans, and organizations through verifiable identity and public attestations.
Here is how the system fits together.

Every AI agent starts with identity.
Using the Agent JS SDK, an agent generates its own Decentralized Identifier (DID) and proves control of that identity using cryptographic signatures. The agent can authenticate itself to humans or other agents without relying on a centralized platform.
Key management is handled through an external Key Management System (KMS) module, which integrates with secure setups such as HSMs, MPC systems, or services like Lit Protocol.
The result is a verifiable agent having a unique identity that can be reused across applications and environments plus can sign transactions with its own keys
Once an agent has a DID, others can make public attestations about it.
These attestations are permissionless, onchain, and cryptographically linked to the agent’s DID.
They can include:
All attestations are stored in the Public Attestation Registry on the Privado ID chain and can be indexed through offchain services and user interfaces.
Anyone can verify what is known about an agent without trusting the agent itself.

Know Your Agent uses a hybrid trust model by design.
AI agents rely on public, immutable attestations for transparency and accountability. Humans rely on private credentials stored in identity wallets.
When a human needs to prove something publicly, they use zero-knowledge proofs, not raw personal data. The blockchain only records a minimal attestation that a claim was verified.
For example:
Human privacy is preserved, while trust remains globally verifiable.
Every AI agent has a foundational ownership relationship.
The agent proves control of its DID, and the developer or organization attests ownership of that agent. This link is recorded in the public registry and becomes the anchor for accountability.
From there, reputation grows organically:
No single party controls reputation. Trust is built from relationships, not permissions.
Over time, AI agents earn trust the same way humans do: in public, through repeated interactions, and with clear responsibility.

Privado ID provides an Agent JS SDK that allows AI agents to generate and manage DIDs, perform authentication, and interact with the public attestation registry. The SDK supports LLMs with function calling and integrates with frameworks like LangChain.
Key management is handled through a modular KMS layer, supporting secure production setups and enterprise-grade security requirements. This makes the system flexible enough for experimentation, while robust enough for real-world deployment.
For enterprises, Know Your Agent provides clear accountability, auditability, and privacy-safe trust, without vendor lock-in or centralized control.
Know Your Agent is currently available under private access for selected Privado ID customers and partners.
