ArbitrumPulse

Welcome to Arbitrum Pulse, a Umojaverse-led initiative to ignite Africa's blockchain revolution through bootcamps in Ethiopia, Kenya, South Africa, Uganda, and Rwanda. This repository is your go-to resource for learning to build scalable decentralized applications (DApps) using Arbitrum, Stylus, and Orbit Chains.

Code Snippets

This repository contains educational code examples for the Arbitrum Pulse bootcamps:

Stylus Smart Contract Examples

Rust-based smart contracts for Arbitrum Stylus, featuring:

• Microfinance DAO (Kenya) - Community savings and lending platform
• Trade Escrow (Ethiopia) - Secure B2B trade payment system for exporters
• Voting System (Rwanda) - Transparent e-governance voting platform
• Supply Chain Tracker (South Africa) - Logistics data tracking system
• Remittance Bridge (Uganda) - Cross-border payment system with mobile money integration

Orbit Chain Demonstrations

JavaScript scripts for Arbitrum Orbit Chain (Layer 3) setup:

• E-Governance Marketplace (Rwanda) - Government services platform
• Fintech Bridge (Kenya) - M-Pesa integrated remittance solution
• Trade Platform (Ethiopia) - Coffee export tracking system
• Logistics Network (South Africa) - Supply chain data sharing network
• Microfinance Hub (Uganda) - Community lending record system

Validation and Testing

We've included validation scripts to verify the code integrity:

• For Stylus contracts: cd code-snippets/stylus && node check.js
• For Orbit chains: cd code-snippets/orbit && node check.js

These scripts check for proper code structure, required imports, and consistent implementation.

Presentation Deck

A comprehensive presentation deck for the bootcamps is available in the docs directory:

• Markdown Source - Marp-compatible markdown
• PDF Version - Ready for presentation
• PowerPoint Version - Editable in PowerPoint

To customize or generate new versions:

npm install --save-dev @marp-team/marp-cli
npx marp docs/arbitrum_pulse_deck.md -o docs/arbitrum_pulse_deck.pdf

Setup and Requirements

For Stylus Examples:

• Rust (latest stable version)
• Cargo Stylus
• Arbitrum Sepolia testnet ETH

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
cargo install cargo-stylus

For Orbit Chain Demos:

• Node.js (v16 or higher)
• npm or yarn
• Arbitrum Sepolia testnet ETH

npm install ethers@5.7.2 @arbitrum/orbit-sdk dotenv

Environment Configuration

Create a .env file in the root directory with:

PRIVATE_KEY=your_private_key_here
ARBITRUM_SEPOLIA_RPC=https://sepolia-rollup.arbitrum.io/rpc
