The new trust primitive
for live human presence
has arrived.
A fast voice based trust layer for wallets, apps, AI agents, and digital systems that verifies a real human is present at the moment of a sensitive action.
A new category, defined by Keywave
Introducing PoH: Proof of Humanness
Designed as a new high risk escalation layer that proves a real human is present before irreversible actions execute.
Built for the moments where CAPTCHA or signature alone is not enough, but KYC is too heavy.
Keywave is the first implementation layer for Proof of Humanness, a new primitive for verifying live human presence during sensitive actions without requiring identity documents.
Why voice?
A fast live signal that is harder to outsource, replay, or fake than clicks, puzzles, or static credentials.
Voice based presence is more direct. It is active, live, challenge based, and moment specific.
If you can't tell when a human is truly present, your trust layer is incomplete.
Bots can imitate behavior. Agents can trigger actions. Farms can scale accounts. Keywave quickly proves live human presence at the moment of execution.
VOICE
VERIFIED
STAMP
Reduced with one live presence layer.
Reliable, scalable human verification is no longer optional and no longer difficult.
How it works
Human verification in seconds.
A fast-expiring challenge for live verification
Authenticate in real time with phrase match, speaker match, and anti-spoof checks
Attest on-chain to Solana, and mirror to EVM on request
Proof that travels.
Your app, their system, a public ledger in the middle. Everyone reads the same receipt.
Built for controlled partner integration
Keywave supports hosted verification, direct API integration, and optional on chain proof receipts for approved partners.
Full API references, OpenAPI access, and implementation guides are available through private partner documentation.
