Hushh Link
Trust is programmable
Hushh Link is the cryptographic layer that ensures every action your agent takes is explicitly approved — and easily revocable
Built with privacy-first architecture and zero-knowledge encryption. Your data remains yours, always.
What Is the Hushh Link?
Hushh Link is the invisible handshake that makes the data economy human again
Hushh Link is a consent validation and logging framework that acts as the trust layer between your data and any agent, brand, or system requesting it.
Issues cryptographically signed consent tokens
Validates all read/write actions against your preferences
Maintains a tamper-proof audit log of every event
Supports human- and agent-readable permissions
Trust is no longer implied. It's explicitly signed
How the Link Works

Shows user reason, data scope, expiration, and granularity options
Logs the consent hash + signature to your Vault
Revokes access for that session/token immediately
All agent calls must pass this gate before data access
Shows every call, timestamp, scope, and revocation history

Consent as Code
Philosophy
Consent isn't a UI toggle — it's a machine-readable contract
Enables agent-to-agent (A2A) and agent-to-knowledge (A2K) data exchanges
Works as the handshake between Hushh PDA and external services
