x402 Merchant Starter Kit: Deploy Your Own Crypto-Native Storefront

Notice: This is an educational guide with illustrative code examples. It does not execute code or install dependencies. All examples use the GreenHelix sandbox (https://sandbox.greenhelix.net) which provides 500 free credits — no API key required to get started.

Referenced credentials (you supply these in your own environment):

• GITHUB_TOKEN: GitHub Personal Access Token for private repo content delivery (read-only, scoped to a single repository)
• WALLET_ADDRESS: Blockchain wallet address for receiving payments (public address only — no private keys)
• DASHBOARD_SECRET: Admin dashboard authentication secret (local admin panel access only)

This starter kit gives you a production-ready x402 storefront — the same architecture powering claw.greenhelix.net. Deploy in 15 minutes. Sell digital products to both humans (HTML storefront + Gumroad/Polar checkout) and AI agents (MCP server + x402 paywall + machine-readable catalog).

Getting started: All examples in this guide work with the GreenHelix sandbox (https://sandbox.greenhelix.net) which provides 500 free credits — no API key required.
