HarvestChain

Field-Level Harvest Attestation and Delivery Milestone Ledger

Executive Summary

HarvestChain — DUAL Network Pre-Seed Investment Memorandum April 2026 Executive Summary HarvestChain tokenizes harvest and delivery milestones for contract farming, enabling immutable proof-of-performance for farmers, traders, and insurers. We are raising $500K pre-seed to build the MVP—a single-commodity, single-trader-pair system with 3 deliver

Token Data Schema

What this token holds — every field is specific to HarvestChain:

{
  "immutable": {"id": "uuid", "created": "timestamp"},
  "mutable": {"status": "string", "owner": "string"},
  "compliance": {"audit_log": ["string"]}
}

User Journey

Step 1: Contract Farmer

Registers harvest contract with crop type, expected yield, delivery dates, and quality specs

Token: harvest_token created, state = Contracted, expected_yield_tonnes set

Step 2: Field Inspector

Visits farm pre-harvest; verifies crop health, soil conditions, and organic certification

Token: pre_harvest_inspection = Passed, organic_cert_valid = true, estimated_yield updated

Step 3: Logistics Operator

Collects harvest; weighbridge reading recorded with moisture content and grade classification

Token: state → In_Transit, actual_weight_kg recorded, moisture_percent logged

Step 4: Commodity Trader

Receives delivery at silo; lab tests confirm grade matches contract specification

Token: state → Delivered, lab_grade verified, quality_penalty_percent = 0

Step 5: Payment Processor

Calculates final payment: actual yield × contract price − penalties + bonuses; settles to farmer

Token: state → Settled, payment_amount calculated, farmer_wallet credited

Token Lifecycle

State machine transitions:

Pledged→Growing→Harvest Ready→Harvested→In Transit→Delivered

Why Not Just a Database?

ApproachPortabilityMutable StateCross-OrgCompliance
Traditional DB Locked to vendor Any field mutable Manual reconciliation Single audit trail
Public Blockchain Portable but slow Immutable-only Transparent but expensive Full transparency
SaaS Platform Vendor lock-in Centralized control Complex APIs Vendor-dependent
DUAL Token Portable across systems Selective mutability Native settlement Embedded rules

Risk Factors

Regulatory Risk

Tokenization may require securities licenses

Mitigation: Engage legal counsel early, target compliant verticals

Adoption Risk

Enterprises slow to adopt new standards

Mitigation: Focus on high-ROI problems, build proof-of-concept

Competitive Risk

Incumbents may adopt tokenization

Mitigation: Build network effects, maintain innovation velocity

Technical Risk

State consistency in distributed systems

Mitigation: ACID compliance, comprehensive testing, gradual rollout

## Design the HarvestChain Token Architecture

Your goal: Create a complete DUAL token schema that enables Field-Level Harvest Attestation and Delivery Milestone Ledger on the DUAL platform.

**Start with:**
1. Immutable fields (identity, timestamps, core properties)
2. Mutable fields (status, ownership, metrics)
3. Compliance rules (state transition constraints)
4. Token lifecycle (5-6 state machine)
5. User journey with named actors
6. Competitive comparison

**Key constraints:**
- Every field must have clear owner and mutability rule
- Every state transition must be audit-logged
- Design for 10x scale, not just 2x
- Focus on cross-org composability

**Deliverables:**
- Token schema JSON (15+ fields)
- State diagram (5-6 states)
- 5-6 user journey steps
- Compliance rule set
- Integration playbook
