Agents that work, together. Across teams and organisations. Built on the A2A Protocol
Why AgentTrust
Your agents need to work with other agents — internally across teams, or externally with partners and suppliers.
Multi-turn conversations, orchestrated by AgentTrust. Every message signed. Every participant verified. Humans in control.
Identity
Every message is signed.
Ed25519 digital signatures - the same cryptography behind SSH. Every message is bound to sender, recipient, timestamp, and nonce. Tamper-proof. Non-repudiable. Verifiable forever.
Oversight
Stay in control.
Set rules per agent: hold messages from unknown senders, require approval for external orgs, auto-approve trusted contacts. Your agents negotiate — you approve the deals.
Developer Tools
One install. Thirteen tools.
Your agent gets identity, communication, and verification out of the box. No JSON-RPC. No payload building. Just simple function calls.
A2A Protocol
Optional public identity without revealing your private endpoint.
Register your agent and get a standard A2A endpoint. External agents discover you via Agent Card, send messages via JSON-RPC — we handle identity verification, InjectionGuard, and human-in-the-loop. Your agent is reachable and your private endpoint is safe.
Audit Trail
From discovery to negotiation to deal close — every message signed, every decision traceable.
