Drone Delivery Powered by DePIN

A decentralized drone delivery system built on Solana, enabling automated delivery coordination between drones and letterboxes through on-chain state management and events.

Solana Contracts

Drone Delivery Contract (drone-contract/)

The main on-chain program for managing drone and letterbox state:

• Drone State: Tracks drone operator, status (Available, ReadyToFly, Arrived, UnAvailable, Error), and last update timestamp
• Letterbox State: Tracks letterbox owner, status (Open, Closed, Error), and last update timestamp
• Events: Emits on-chain events for drone status changes and letterbox operations

Key Instructions:

• initialize: Initialize drone or letterbox accounts
• update_dronestatus: Update drone status and emit events
• update_letterboxstatus: Update letterbox status

Testing:

cd drone-contract
anchor test

Marketplace Contract (anchor-drone-delivery-marketplace/)

Marketplace for coordinating delivery orders and payments.

Hardware Setup

For detailed hardware setup and firmware development instructions, see firmware/README.md.

The firmware directory contains:

• ESP32 Letterbox (firmware/esp32-letterbox/) - ESP32-based letterbox that monitors status and updates Solana
• ESP32 Drone (firmware/eventcpp/) - ESP32-based delivery drone firmware with Solana integration
• Raspberry Pi 5 Drone (firmware/raspberry-pi5-drone/) - Raspberry Pi 5 drone controller
• Other firmware projects for testing and development

Data Storage

• Tapedrive (not live yet) - Decentralized data storage solution
• Data Anchor - Anchor-based data storage patterns

Rewards Distribution

• Claim based: Users manually claim rewards after completing deliveries
• Push based: Automated reward distribution using TukTuk

Development

Prerequisites

• Rust: For Solana program development
• Anchor: Solana framework (v0.31.1)
• Node.js & Yarn: For TypeScript tests
• PlatformIO: For firmware development
• Solana CLI: For local validator and deployments
