AutoChain

Warranty claim validation across serialized parts

Custody stateP1

AutoChain

Warranty claim validation across serialized parts. Warranty fraud and claim delay come from weak linkage among part identity, vehicle records, repair evidence, and coverage rules.

AutoChain is strongest when treated as a governed state machine, not a static token. The object must carry enough identity to be trusted at mint, enough mutable state to reflect the real workflow, and enough audit history for a third party to decide whether the current state is reliable.

Strategic thesis

Why this wedge exists

A warranty claim can be checked against serialized part state, vehicle state, dealer role, and policy rules before payout.

The first buyer is Automotive OEMs and dealer networks. They don't need a generic blockchain story; they need a way to reduce disputes, speed approval, and make the current status of a workflow independently checkable.

State Dual manages

Claim filing, part verification, coverage check, repair approval, reimbursement, and fraud flags.

The important point is not the number of states. It's that each transition has an actor, an allowed action, evidence, and a durable audit record. That turns operational workflow into an inspectable object.

Example object schema

{
  "template": "autochain",
  "category": "Custody state",
  "immutable": {
    "asset_id": "set_at_mint",
    "issuer_id": "set_at_mint",
    "serialization_standard": "set_at_mint",
    "origin_proof_hash": "set_at_mint",
    "created_at": "set_at_mint"
  },
  "mutable": {
    "custody_holder": "updated_by_event",
    "location_status": "updated_by_event",
    "verification_status": "updated_by_event",
    "exception_status": "updated_by_event",
    "last_handoff_at": "updated_by_event"
  },
  "rules": {
    "allowed_states": ["Claimed","Part Verified","Coverage Checked","Approved","Paid","Rejected","Closed"],
    "first_buyer": "Automotive OEMs and dealer networks",
    "audit_required": true
  }
}

This schema is intentionally scoped. A credible first product should prove one object type, one core state machine, and a small number of high-value integrations before expanding into a platform.

User journey

  1. 1

    Issuer: Claimed

    The AutoChain object is created with immutable identity, owner, and rule metadata.

  2. 2

    Operator: Part Verified

    An event moves the object into "Part Verified", preserving the previous state and the actor that triggered the change.

  3. 3

    Verifier: Coverage Checked

    An event moves the object into "Coverage Checked", preserving the previous state and the actor that triggered the change.

  4. 4

    Counterparty: Approved

    An event moves the object into "Approved", preserving the previous state and the actor that triggered the change.

  5. 5

    Auditor: Paid

    An event moves the object into "Paid", preserving the previous state and the actor that triggered the change.

  6. 6

    Automation: Rejected

    An event moves the object into "Rejected", preserving the previous state and the actor that triggered the change.

  7. 7

    Administrator: Closed

    An event moves the object into "Closed", preserving the previous state and the actor that triggered the change.

Event model

Dual becomes useful when outside systems stop being passive records and start becoming evidence sources for state transitions.

  • ERP or WMS shipment events
  • scanner/NFC/serial verification
  • inspection or authenticator attestation
  • regulator or marketplace query

Each event should answer four questions: who produced it, which object it affects, which transition it requests, and which proof should be retained for audit.

Why not just a database?

Traditional system

Dealer systems and OEM systems reconcile after the fact; the claim itself is not a shared governed object.

That's acceptable when one organization owns the full workflow. It breaks down when multiple parties need to trust the same current state without relying on a single application owner.

Dual stateful object

Dual separates immutable identity, mutable lifecycle state, compliance checks, and event history. Participants can inspect the current object state, verify the transition path, and use the same state as input to payment, access, reporting, or downstream automation.

90-day MVP

One OEM, one dealer group, one valid claim, one duplicate claim rejection.

  • Define the template and allowed state transitions.
  • Mint test objects with realistic identity and ownership data.
  • Wire one external event source into the Event Bus.
  • Trigger one successful transition and one rejected transition.
  • Expose a query view that proves current state and transition history.

Proof assets required

  • Claim schema
  • Coverage rule
  • Part serialization
  • Fraud rejection event

These assets are the difference between a concept note and a buildable wedge. Without them, the page is only a narrative; with them, it becomes a product specification.

Operating metrics

  • handoff latency
  • exception rate
  • audit response time
  • percentage of objects with complete provenance

These are the metrics that should be visible in the pilot dashboard. They also give sales, implementation, and investor conversations a concrete way to judge whether Dual is improving the workflow.

Commercial wedge

The first commercial motion should sell a narrow operational outcome, not broad tokenization. For AutoChain, the wedge is: validate a claim. Price around the workflow value: fewer disputes, faster settlement, cleaner audit, lower fraud, or lower manual reconciliation.

Expansion should follow the state graph. Once the first transition is trusted, add the next actor, then the next integration, then the next reporting surface. That keeps the product grounded in workflow proof rather than speculative asset creation.

Risks and controls

  • bad upstream data at mint. Control: define the trusted source, log every mutation, and keep manual override paths explicit.
  • participants resisting shared custody proof. Control: define the trusted source, log every mutation, and keep manual override paths explicit.
  • physical/digital mismatch if scanning controls are weak. Control: define the trusted source, log every mutation, and keep manual override paths explicit.

Implementation playbook

  1. Map the workflow: identify the actor responsible for each state and the evidence required for each transition.
  2. Create the template: split data into immutable identity, mutable state, and compliance rule fields.
  3. Mint sample objects: use realistic IDs, timestamps, owners, and source-system references.
  4. Connect one event: choose the event that makes the state change economically valuable.
  5. Reject one bad action: demonstrate that Dual blocks invalid transitions before downstream settlement.
  6. Expose audit: show current state, previous state, actor, timestamp, evidence hash, and rule result.

Build prompt

Create a Dual template for AutoChain. Model immutable identity fields, mutable lifecycle state, compliance checks, and event inputs. Then emit one test object and move it through: Claimed → Part Verified → Coverage Checked → Approved → Paid.

Include:
- object schema
- transition rules
- event payload examples
- one rejected transition
- audit query output
- MVP dashboard fields

Use this as a scoped wedge: prove one governed state transition, one external event, and one audit query before expanding the workflow.
