The Hardware
Layer.
Stop validating software. Start validating silicon.
Invariant filters 99% of automated traffic by verifying the Trusted Execution Environment (TEE) in user devices.
The Zero-Cost Attack.
Generative AI creates infinite fake identities at $0.001 per instance. Traditional checks (IP, Email, CAPTCHA) are software-based and easily spoofed.If identity is free, trust is impossible.

We anchor identity to the Android Keystore System. To forge an Invariant identity, an attacker must purchase a physical device ($40+) and maintain power.We turn spam from a software problem into a financial problem.
READ INTEGRATION GUIDEThe Verification Standard
1. Challenge
The protocol issues a cryptographic nonce to the client. The device must sign this nonce inside its Secure Enclave (StrongBox).
2. Attestation
The device returns an X.509 Certificate Chain rooted in the Google Hardware Trust Anchor. Emulators cannot produce this root.
3. Verification
Our Rust backend parses the ASN.1 chain, verifies the signature, and confirms the device is physical, not virtual.
