The Trust Fabric for the Agentic Economy
A modular, API-first infrastructure for AI trust — verifiable DIDs, VC-issued mandates, a deterministic allow / observe / block / escalate policy engine, Hedera-anchored signed evidence and the HCS-28 Trust Index, exposed as composable engines.
Trust as programmable infrastructure
Metamynd turns identity, authority, governance, evidence, audit, risk, certification and trust into reusable platform services — composable through one API-first Trust Fabric.
One platform, composable engines
Each engine is independently useful and works together across the Trust Fabric.
Trust Fabric
The substrate that links identity, policy, evidence and the trust index into one consistent, on-chain view.
- Deterministic policy-core
- Identity (DIDs)
- Signed evidence on Hedera
- The Trust Index
Identity Engine
Issues each agent a verifiable, self-certifying DID and proves control of its key — the root every other engine trusts.
- did:hedera / did:key
- Key proof (verify-key / BYOK)
- Public DID resolver
- HCS registry anchoring
Ownership & Delegation
Binds an agent to its owner and to a VC-issued mandate — with instant revocation.
- Verified principal (KYC/KYB), or a disclosed free-tier allowance
- VC-issued mandate (scope, caps, merchants)
- Resource scope — which systems and data
- Sub-delegation that can only narrow
- Delegated issuance
Agent Passport
A signed, portable snapshot of an agent's identity, ownership, declared purpose and current capabilities — composed from data the platform already tracks.
- Signed identity + capability snapshot
- Composed from existing identity/version/assurance data
- Independently revocable from containment
- Reissued as the agent's profile changes
Credential Authority
Issues, presents and verifies W3C Verifiable Credentials — with selective disclosure and on-chain anchoring.
- Verifiable Credentials (identity, entity, mandate)
- BBS selective disclosure
- Ed25519 platform issuer
- Anchoring & revocation
Policy Engine
The deterministic core: composes Standards & SOPs from atoms and returns allow / observe / block / escalate — no LLM in the decision.
- Atom → molecule → SOP/Standard
- allow / observe / block / escalate
- Deterministic & re-derivable
- Live edits, no redeploy
Governance Engine
The authorize gate that runs the policy on every signed action, in cooperative or trustless mode, with human-in-the-loop escalation.
- The authorize gate (MAGP)
- Escalation → owner approval
- Standards compliance check
- Cooperative & trustless modes
Action Passport
A signed, single-use proof that one exact action was authorized — bound to that authorization alone, carrying no raw payload content.
- Issued only on allow / observe
- Bound 1:1 to a single authorization
- No amount, merchant or payload data
- Paired Execution Receipt proves payloadMatch
Credential Vault
Encrypted-at-rest storage for the upstream credentials your agents need — released just-in-time, only to a gateway, only against a currently-active Action Passport.
- AES-256-GCM at rest
- One release path, gated on two factors
- Tenant derived from the passport, never the caller
- Every attempt audited, plaintext never logged
Evidence Engine
Signs every decision, batches them into a Merkle root, anchors it on Hedera, and lets anyone verify a record offline.
- Ed25519-signed receipts
- Merkle batching
- HCS anchoring
- Offline verification (magp-evidence)
Audit Engine
Turns the signed evidence into a reconstructable, regulator-ready record — with inclusion proofs against an anchored root.
- Immutable audit / regulator log
- Merkle inclusion proofs
- Reason-code decision trail
- Downloadable, offline-verifiable
Supervisory Access
A scoped, revocable seat for a regulator or supervisor — with a hash-chained log of everything they read.
- Grant-based, time-bounded access
- Scoped to decisions, controls or proofs
- Hash-chained access log
- Readable by the supervised organisation
Trust Engine
Computes a signed, HCS-28 trust score per agent from its verified identity and governance track record.
- HCS-28 Trust Index
- Weighted adapters + coverage
- Drift monitoring
- Signed, publishable records
Risk Engine
Routes risk in proportion to impact — high-risk actions and low-trust counterparties escalate to a human, they don't fail silently.
- Risk-tiered escalation
- Policy thresholds (atoms)
- Trust-guidance routing
- Incident & near-miss reporting
- Proportional, not binary
Registry Services
Authoritative, federatable on-chain registries for agent identities and published trust records.
- HCS-2 identity registry
- Agent DID registry
- HCS-28 trust registry
- Federatable / discoverable
Certification Authority
Issues living certifications backed by assurance-graded verification, continuous evidence and the Trust Index.
- Assurance-graded KYC/KYB
- Living certificates
- Digital trust marks
- Auto-revoke on drift
AI Sandbox
A public, no-KYB environment that hands you a governed agent — first allow / observe / block / escalate in minutes.
- Public no-KYB endpoint
- Shared, pre-issued test agent
- Live allow / observe / block / escalate
- Same code to production
Incident Management
Contains a misbehaving agent immediately — revoke its mandate, fail closed, and keep the signed record.
- Instant mandate revocation
- Fail-closed containment
- Escalation queues
- Post-incident evidence
Event Fabric
The signal backbone — verification and status webhooks, escalation polling and evidence-flush events.
- Verification / contact webhooks
- Escalation status polling
- Evidence batch flush
- Real-time trust signals
Security Architecture
Security-by-design: signed, fail-closed, PII encrypted at rest, only commitments on-chain, and quantum-resistant channels.
- Ed25519 + hybrid post-quantum
- Encryption at rest (AES-256-GCM)
- On-chain commitments, not PII
- Fail-closed by default
Deployment Architecture
Runs on Hedera (testnet or mainnet), self-hostable, with configurable, sovereign HCS topics.
- Hedera testnet / mainnet
- Self-hostable / sovereign
- Configurable HCS topics
- Cloud / on-prem / federated
