TETRACT.

The cryptographic chain-of-custody for autonomous action. Tetract binds AI agents, humans, organizations, and products into one verifiable, regulator-shaped trust graph — built for the agentic economy that ships in August 2026.

Four-Node Graph Verifiable Edges Regulator-Shaped Agentic-First

Problem · 5 gaps converging on Aug 2026

Agents act. Nobody is on the hook.

A Claude Code agent commits to your main branch. An Atlas agent buys flights on your card. A Comet agent exfiltrates a 1Password vault — actually documented, November 2025. There is no cryptographic chain of custody answering who authorized what, on whose behalf, scope, validity, revocability. OAuth 2.1 is single-hop. The 2026 IETF AIP draft found no shipped standard satisfies more than 4 of 7 properties for genuine agentic delegation.

01 Accountability

Agents act without audit trails

OAuth 2.1 (the MCP de-facto since June 2025) is single-hop, no holder-side scope attenuation. Reconstructing "which human → which agent → what scope" is impossible after the fact.

02 Liability

Identity ≠ accountability

Stripe SPT, Visa TAP, Google AP2 (all launched Sep–Oct 2025) cryptographically authorize a payment. None carry forward to dispute, audit, or AI Act Article 14 oversight. IBM 2025 made the critique explicit.

03 One-Node Stacks

Every player owns a vertex, no one owns the graph

Worldcoin, Humanity, Alien, Billions, Spruce, ENS — node primitives. Avery Dennison, Arianee, Circulor — product nodes. Nobody ships the verifiable edge. ToIP/DIF Trust Graph WG started 30 Sep 2025 because the gap is now standards-track admitted.

04 DPP Islands

Product passports, no agents attached

30B+ items on atma.io. Volvo cobalt traceability. Moncler tokens. None of them connect issuing org's verifiable identity → employee credential → AI agent that updates the DPP. ESPR Article 13 mandates a Registry by 19 Jul 2026 — without specifying the agent edge.

05 12-Month Cliff

Three regulations, one window

EU AI Act Art. 50 (2 Aug 2026). ESPR Art. 13 DPP Registry (19 Jul 2026). Battery Passport per-unit (18 Feb 2027). EUDI Wallet, EUDR, Sunrise 2027 stacking on top. One stack satisfies all four regimes — or eleven incompatible vendors integrate for four years.

06 Insight

The full graph is unclaimed

a16z named "Know Your Agent" the 2026 identity primitive. Catena Labs raised $18M for it — in payments only. Astrix went to Cisco for ~$300M — enterprise NHI only. No vendor has the cap-table to ship the full four-node graph. We do.

Thesis

Worldcoin proved humanity.
ENS proved naming.
Stripe proved payment.
Avery Dennison proved the product passport.
Nobody has proven the relationship.

— Tetract is building the verifiable edge.

Solution · Four Nodes, One Graph

Every agent action is a four-witnessed act.

Each entity gets a W3C Decentralized Identifier. Each "passport" is a profile of Verifiable Credentials 2.0. Each edge — employed-by, produced-by, delegated-by, owned-by, authorized-for, attested-by — is itself a signed, scope-attenuated, revocable credential. Selectively disclosable via SD-JWT, BBS+, or ZK-SNARK as policy requires.

did:human:*

Human Passport

Proof-of-personhood (World ID / Humanity / Billions / EUDI 2.0 PID). KYC/AML. Roles. Selective disclosure via ZKP — prove "agent is authorized" without revealing the principal.

did:org:*

Organization Passport

eIDAS 2.0 LPID. GS1 GLN. LEI. Industry consortia (CIRPASS, GS1 BeLu Solution Partner). ESPR / ESG compliance status. The legal-person anchor that lets every downstream credential carry liability.

did:product:*

Product Passport (DPP)

GS1 Digital Link → DID → ESPR-compliant VC bundle. Manufacturing, sustainability, supply chain, ownership. Built on Fluxy.One backbone — 27 languages, AI parsing, prEN 18220 conformance.

did:agent:*

AI Agent Passport

Architecture, version, training-data lineage. Risk classification per EU AI Act. Operator delegation chains. Compatible with MCP, A2A, AP2, ERC-8004, AGNTCY, NANDA AgentFacts. Eleven verifiers; one SDK.

Why Now · Regulatory Cliff

Three regulations. One agentic explosion. Zero unified trust layer.

EU's regulatory window opens in 12 months and closes hard. Every agent platform shipped in 2025–26. Every standard hit Recommendation. Every vendor staked a single node. Nobody shipped the graph.

Architecture · 7 Layers, 1 SDK

The Rosetta Stone of agent identity.

Eleven parallel agent-identity protocols are alive in 2026 (MCP, A2A, AP2, x402, ACP, ANP, AGNTCY, NANDA, Web Bot Auth, ENSIP-25, ERC-8004). Tetract emits the right attestation per surface. Single integration; eleven verifier compatibilities.

Use Cases · 10 from Day One

Where the trust graph earns its keep.

Every use case is a four-node act. Every act is provable in one credential chain. Every chain reduces to agent → human → org → product — a structure traditional IAM cannot represent.

⌘

Verifiable code commits

Every Claude Code / Cursor / Devin commit signed, scoped, audited. Engineering forensic ledger.

Browser-agent commerce

Atlas / Comet / Goose buy with merchant-verifiable authority alongside Stripe SPT / Visa TAP / AP2.

⊛

Agentic supply-chain

Textile MCP agent updates DPPs hourly. ESPR Art. 7 + 13, CIRPASS-2, EUDR satisfied in one chain.

Healthcare agent

Clinical agent → physician's medical-license credential → hospital org DID. HIPAA/GDPR audits in seconds.

↔

Cross-border A2A commerce

Latvia SIA agent ↔ Delaware C-Corp agent. Both KYB-satisfied. x402 stablecoin settlement.

Brand customer-service agent

Article 50(1) chatbot transparency + GDPR controller ID + sector authorization in one credential.

↻

Resale-market provenance

Vestiaire agent presents chained ownership credentials anchored to original Moncler DPP. Counterfeits cannot present the chain.

AI journalism provenance

Byline carries Tetract publisher-authority credential + human editor countersignature. EU GPAI Code of Practice satisfied.

⚡

Battery passport · Feb 2027

Every >2 kWh battery: lifecycle credential chain. GBA Battery Pass / Catena-X / DKE Spec 99100 by default.

⊕

Agent-spawned-agent governance

Planner spawns 3 executors with attenuated scope. Traditional IAM cannot represent this. Tetract was built for it.
