Proof Of Human
SOVEREIGN

AI agents can act for you. AT1C makes sure they only act with your permission — and proves it, cryptographically, every time.

The evidence layer for human control of AI

Read the Founding Document

"Don't trust us. Verify the receipt."

Open protocol · MIT licensed · EU AI Act ready

Right now, you can't prove what you approved

AI tools make decisions. Platforms control your access. Your agents act — and there is no cryptographic record that you said yes.

AI agents lack intention, so liability can only attach to the human who approved the action. But only if there is evidence of what they approved.

Without AT1C

Your agent acts. There is no proof you approved it. Under the EU AI Act, that is a liability. In court, that is no evidence.

With AT1C

Every action is backed by a cryptographically signed proof of your approval — independently verifiable by any auditor, regulator, or counterparty.


Four steps. One receipt. Permanent proof.

01 — REQUEST

Request

Agent asks permission for a specific action — scoped, named, bounded.

02 — APPROVE

Approve

You explicitly grant or deny it. Your key. Your decision. No platform in between.

03 — PROOF

Proof

Signed receipt generated — timestamped, cryptographic, your permanent evidence.

04 — VERIFY

Verify

Any party verifies independently — no trust needed, no intermediary required.

No wallets. No seed phrases. No complexity. Register in minutes.

Personal agents. Enterprise fleets. Regulated industries.

AT1C works for anyone whose AI agent takes actions on their behalf.

Three-part identity. Yours forever.

AT1C is more than a compliance tool. It is the foundation of a model where humans own their digital identity — across every system, every AI, and every lifetime.

🌐

Public identity

Your verified self — provable, portable, not owned by any platform.

🔒

Private identity

Your anonymous space — protected, untracked, under your control.

Lifecycle identity

Inheritable. Transferable. Your digital life outlives you on your own terms.

Identity belongs to the individual, not the platform. AI agents should serve humanity, not control it. Ownership of self is the foundation. Freedom is the AT1C Protocol. Humans first.

No platform owns it. No institution brokers it. The receipt lives with you.

Start today. No credit card. No complexity.

Register your first agent in minutes. The private key stays on your device. AT1C never holds it.
