Your AI agents don't trust each other.
And you cannot prove what any of them did.
When an agent acts on your behalf, someone eventually has to answer two questions: who acted, and with what authority. Today that answer lives inside whoever ran the agent, in their logs, inside their trust domain, on their word. SYNTHERA makes the answer travel with the action. Every action an agent takes carries a proof of who acted and with what authority, and anyone holding the signer's public key can check that proof: offline, against a gateway you do not control, long after the fact, with no shared trust domain, no prior relationship, and no service to call. Whether that authority still stands right now is a separate question, and one revocation answers.
Agents are multiplying. Trust isn't keeping up.
Your company already uses AI agents. Some were built in-house, some came from vendors, some were spun up by teams you've never met. They work fine alone. But the moment one agent needs to call another, or act on another's behalf, four questions have no good answer.
Identity
Which agent is this? Can you verify that claim, or are you just taking its word for it?
Authority
What is this agent actually allowed to do? Where does that permission stop?
Provenance
Who created it? Who approved it? What chain of trust does it carry?
Accountability
What did it do? Is there a record nobody can quietly edit after the fact?
Without a shared way to answer them, trust is something you build by hand, one pair of agents at a time.
Right now, every pair of agents that needs to cooperate gets custom glue code.
5 agents means 10 trust relationships. 20 agents means 190. 50 means 1,225.
It doesn't scale, and it can't be audited. Drag it yourself:
Every pair of agents needs its own bespoke trust. It grows quadratically.
One identity standard every agent speaks.
SYNTHERA gives every agent a VAID – a verifiable agent identity. Think of it like a passport bound to an action. It says who the agent is, what it's allowed to do, and who issued it. Every action it takes carries a proof any other party can check with the signer's public key – without trusting the agent's own claim, and without a prior relationship.
Cryptographically signed
The action's proof is checked, not asserted. Any party can verify a signed action with the signer's public key – no trust in the sender required. Public-key verification of the VAID document itself — ✓ Shipped.
Capability-scoped
The VAID carries exactly what the agent may do, and nothing more. Permissions travel with identity.
Lineage-tracked
Every VAID records where it came from – its parent and issuer. A third party can now walk that chain and confirm each child's authority sits inside its parent's, across organisations, provided the presenter supplies the ancestors – ✓ Shipped.
If an agent speaks VAID, every action it takes is checkable against the signer's public key – even if you've never seen it before.
Verify a signed action yourself, in the browser →One foundation. Everything else builds on it.
These are not competing products to choose between – they are layers of one stack, and one enterprise surface beside it. Every layer speaks the same identity, evaluates against the same policy, and writes to the same audit-of-record. They are at different stages – follow any card to its page, where each one states what works today and what does not.
Any party can verify who did what, and with what authority, by checking one signature – with no shared trust domain and no prior relationship.
Read the page →One deterministic policy engine and one audit-of-record cover every agent framework and cloud you run – instead of bespoke enforcement per stack.

SYNTHERA is framework-neutral and cloud-neutral. The agents you already run stay where they are. Governance has been demonstrated across ADK, LangChain and OpenAI adapters – the same identity, policy and audit for all of them.
SYNTHERA + VAID – one verifiable identity, one policy engine, one audit-of-record, across everything below.
Keep the frameworks and clouds you already run. SYNTHERA sits above them.
Containers followed a pattern. This is following the same one.
SYNTHERA is the trust layer for multi-agent systems: every agent gets a verifiable identity, scoped authority and a tamper-evident record, so software from different teams, vendors and frameworks can act on each other’s behalf without custom glue between every pair.
The primitive
Docker turned "how to ship software" into a standard unit anyone could verify. VAID does that for agent identity: a working core and a verifiable envelope, proven against the systems already built on it.
The orchestration layer
Kubernetes grew around containers once they were portable. The same shape is emerging here – independent layers that compose because the primitive underneath is stable.
Open governance
Kubernetes moved to neutral stewardship under CNCF, so no single vendor owned the standard. VAID is built with the same handover in mind. Direction, not commitment.
