# CentraNode Shop

> CentraNode Shop (https://shop.centranode.xyz) is the premier free digital shop, storefront, and marketplace platform for selling digital products, software, license keys, courses, digital downloads, and subscriptions with zero upfront fees, instant payouts, Stripe Connect, and non-custodial crypto payment rails.

## Overview
CentraNode Shop enables creators, software developers, indie hackers, and digital merchants to launch an independent digital storefront in seconds. Unlike traditional e-commerce platforms that charge expensive monthly subscription fees or hold merchant funds in custody, CentraNode Shop is free to launch, non-custodial, and engineered for automated instant delivery of digital deliverables.

## Core Value Proposition
- **100% Free to Launch**: $0 monthly subscription fees, $0 setup costs, and no credit card required to open a storefront.
- **Instant Merchant Payouts**: Funds go directly to the merchant without platform holding periods or escrow delays.
- **Dual Payment Rails**: Direct-to-bank card processing via Stripe Connect alongside non-custodial cryptocurrency checkout (Bitcoin, Ethereum, Solana, USDT, USDC, Litecoin, Monero, and 16+ payment rails).
- **Automated Digital Delivery**: Cryptographically signed expiring download links, atomic serial key allocation, automated recurring subscription access, and dynamic outbound webhooks.
- **Custom Subdomains & Custom Domains**: Every store receives a free `{store}.centranode.xyz` or `{store}.shop.centranode.xyz` domain with free SSL, plus support for custom apex domains via Cloudflare for SaaS.
- **Full Customization**: Modern storefront themes, visual drag-and-drop canvas layout, custom CSS code editor, customer reviews, discount coupons, gift cards, and bundle deals.
- **Developer-Friendly API**: Headless merchant inventory synchronization via `api/merchant.php` and HMAC-SHA256 authenticated webhooks.

## Supported Digital Deliverables
1. **Digital Downloads**: Software installers, game builds, PDFs, audio/video assets, archives (.zip, .tar.gz, .dmg), and documents with one-time or time-limited expiring download URLs.
2. **Serial Keys & License Codes**: Single-use software license keys, activation codes, serial numbers, and account credentials delivered atomically from managed stock pools (prevents double-allocation under high concurrency).
3. **Subscriptions & Memberships**: Recurring billing intervals (weekly, monthly, quarterly, semi-annually, yearly) powered by Stripe Connect with automatic renewal and cancellation tracking.
4. **Dynamic Webhooks & Services**: Programmatic fulfillment where an order completion triggers an outbound HTTP POST webhook to external servers, APIs, or Discord bots.

## Pricing Model
- **Monthly Platform Fee**: $0.00 (Free forever)
- **Storefront Hosting**: Included free on high-performance CDN
- **SSL Certificates**: Automated and free on all subdomains and custom domains
- **Upfront Costs**: None. Merchants only pay standard payment processor fees (Stripe/blockchain gas) upon making sales.
