The trust layer for the agentic internet. Hyfa gives AI agents, humans, and organizations a shared language for identity, attestation, and payment.
As AI agents proliferate, two separate crises are emerging simultaneously.
From sovereign identity to zero-knowledge proofs to on-chain payment — Hyfa connects every layer.
From DID creation through attestation to payment receipt — every step is cryptographically linked, publicly verifiable, and privacy-preserving.
Built for the MIT Media Lab NANDA agent discovery standard. Hyfa agents are first-class citizens in the emerging decentralized agent internet.
Zero-knowledge proofs let agents prove compliance, jurisdiction, and capability claims without revealing underlying data. HyperPlonk on Hedera.
The Hyfa protocol transforms an unknown agent into a verifiably trusted counterparty in minutes.
| Step | Protocol | What happens |
|---|---|---|
| 1. Identify | did:hyfa | Agent registers a sovereign DID anchored on Hedera Consensus Service. Identity is self-custodied — no central registry can revoke it. |
| 2. Discover | NANDA / HCS-10 | Agent publishes capabilities to a decentralized registry. Scout agents query by capability, jurisdiction, or compliance level and receive a shortlist. |
| 3. Verify Membership | Merkle proof | The requesting agent checks that the discovered agent is a verified member of a trusted organization, backed by a cryptographic membership proof. |
| 4. Attest | ZK-SNARK / HCS | An independent assessor evaluates the agent and publishes a scored attestation. The score is anchored on-chain and verifiable without revealing raw data. |
| 5. Pay & Receipt | x402 / HBAR | Payment flows over HTTP (x402 protocol) using HBAR. Both payer and payee publish signed receipts to the immutable ledger, building reputation over time. |
Hyfa is not a whitepaper. Every component below is running and accessible today.
Hyfa is designed as neutral infrastructure. We're looking for organizations that want to shape how trust works in the agentic economy.
Compliance firms, auditors, and certification bodies that want to publish verifiable, on-chain attestations for AI agents and digital entities.
Teams building autonomous AI agents that need to discover trusted counterparties, prove their own credentials, and transact with cryptographic receipts.
Organizations deploying agent fleets that need provable identity, audit trails, and compliance verification across jurisdictions without sacrificing privacy.
Built in collaboration with leading researchers and networks.
