Trust Infrastructure · v0.1 · Testnet Live

Universal Identity Infrastructure
for Digital Entities

The trust layer for the agentic internet. Hyfa gives AI agents, humans, and organizations a shared language for identity, attestation, and payment.

The Problem

Discovery without verification is dangerous

As AI agents proliferate, two separate crises are emerging simultaneously.

Discovery

  • Agents cannot find each other in a decentralized world
  • No standard registry for AI service capabilities
  • Every integration requires custom discovery logic
  • Fragmented ecosystems prevent interoperability

Verification

  • Found an agent — but can you trust it?
  • No way to verify compliance, jurisdiction, or capability claims
  • Attestation is siloed, expensive, and non-transferable
  • Privacy-preserving verification is nearly impossible

Hyfa solves routing for trust."

What We Built

A complete trust stack

From sovereign identity to zero-knowledge proofs to on-chain payment — Hyfa connects every layer.

NANDA / HCS-10
Agent registry
Identity
did:hyfa DIDs
Org & Agent
Attestation
ZK proofs
On-chain anchors
Payment
x402 / HBAR
Verifiable receipts
Reputation

Immutable ledger

Complete trust chain

From DID creation through attestation to payment receipt — every step is cryptographically linked, publicly verifiable, and privacy-preserving.

🌐

NANDA-native

Built for the MIT Media Lab NANDA agent discovery standard. Hyfa agents are first-class citizens in the emerging decentralized agent internet.

🔒

Privacy & proofs

Zero-knowledge proofs let agents prove compliance, jurisdiction, and capability claims without revealing underlying data. HyperPlonk on Hedera.

How It Works

Five steps from unknown to trusted

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.

Partner With Us

The trust layer needs many voices

Hyfa is designed as neutral infrastructure. We're looking for organizations that want to shape how trust works in the agentic economy.

🏛

Attestor Organizations

Compliance firms, auditors, and certification bodies that want to publish verifiable, on-chain attestations for AI agents and digital entities.

🤖

Agent Developers

Teams building autonomous AI agents that need to discover trusted counterparties, prove their own credentials, and transact with cryptographic receipts.

🏢

Enterprises

Organizations deploying agent fleets that need provable identity, audit trails, and compliance verification across jurisdictions without sacrificing privacy.

Founding Partners

Built in collaboration with leading researchers and networks.

MIT Media Lab · NANDA
Networked Agents and Decentralized AI research group. Hyfa implements the NANDA agent discovery standard and contributes to the open specification.
Hedera Hashgraph
Hedera Consensus Service provides the immutable append-only ledger backbone for DID anchoring, attestation storage, and reputation events.
Open Standards
Built on W3C DID, W3C Verifiable Credentials, HCS-10, HCS-11, and x402 open standards. No proprietary lock-in — interoperate with any conformant system.
