What it does

This skill gives Claude Code deep knowledge of the Arbitrum development stack so it can help you:

• Scaffold a monorepo with Stylus Rust contracts, Solidity contracts, and a React frontend
• Write and test smart contracts using the Stylus Rust SDK or Foundry
• Run a local Arbitrum devnode for development
• Build frontend interfaces with viem and wagmi
• Deploy contracts to Arbitrum Sepolia and Arbitrum One
• Interop across contract languages (Stylus and Solidity)

Quick Start

bash <(curl -s https://raw.githubusercontent.com/hummusonrails/arbitrum-dapp-skill/main/install.sh)

Then start Claude Code and ask it to build something:

> Create a Stylus contract for an ERC-20 token with a React frontend

That's it. The skill loads automatically.

<details> <summary><strong>Install from ClawHub</strong></summary> <br>

Stack

<details> <summary><strong>Prerequisites</strong></summary> <br>

The skill will guide you through installing these, but for reference:

• Rust 1.81+
• cargo-stylus: cargo install --force cargo-stylus
• Foundry: curl -L https://foundry.paradigm.xyz | bash && foundryup
• Docker for the local devnode
• Node.js 20+ and pnpm

</details>

Usage examples

Once installed, start a Claude Code session and try:

> Help me create a new Arbitrum dApp
> Write a Stylus contract that implements an ERC-20 token
> Set up my local devnode and deploy my contract
> Add a frontend that reads from my deployed contract
> Help me write tests for my Stylus contract
