supply_chain

🌱 Project Overview

As part of the Encode Solana/Rust Bootcamp, we built a decentralized supply chain traceability system using Solana blockchain technology. This project enables immutable tracking of specialty products from origin to consumer, addressing critical issues like:

• Lack of transparency in traditional supply chains
• Fraud risks
• Ethical compliance challenges
• Difficulty in product origin verification

Key Features:

• Immutable product history tracking
• QR code-based consumer verification
• Real-time stakeholder access
• Smart contract-based provenance verification

🧰 Technical Stack

• Blockchain: Solana (Anchor framework)
• Frontend: Next.js + Tailwind CSS + React
• UI Library: Gill
• Development Tools: create-solana-dapp SDK
• Smart Contracts: Rust (Anchor)
• Wallet Integration: Solana Web Wallet

🚀 Getting Started

1. Dependencies

pnpm install

2. Anchor Setup

pnpm run setup

This creates a new keypair, updates Anchor config, and syncs the program ID

3. Build & Run

pnpm anchor-build
pnpm anchor-localnet

4. Testing

pnpm anchor-localnet
pnpm anchor-test

5. Deployment

pnpm anchor deploy --provider.cluster devnet

6. Sart the Web App

pnpm dev

React app with Solana program client integration

7. Build the Web App

pnpm build

⚠️ Important Notes

Seed Consistency: Ensure your seed generation method is identical across:

• Anchor program
• Next.js frontend

🛠️ Future Improvements & Enhancements

🧩 Customer Onboarding

• Customizable Workflows
  Tailor the platform for different industries (agriculture, manufacturing, etc.) with configurable tracking rules and compliance checks.
  Example: Auto-assign product categories, set required tracking parameters, and define stakeholder access levels.

• Batch Tracking System
  Group-track multiple products for raw material traceability:

  • Track multiple SKUs in a single shipment
  • Maintain cross-referenced data for inventory management
  • Enable B2B supplier verification through shared product metadata

💳 Integrated Payment Solutions

• On-Chain Transactions
  Implement direct Solana-based payments for:

  • Product purchases
  • Service fees
  • Royalty splits

• Smart Contract Escrow
  Automate fund release with conditions:

  • Payment upon delivery confirmation
  • Escrow for quality assurance compliance
  • Automated refunds for non-conformance
