Cryptoon

The global manga and webtoon industry generates over $30 billion annually, yet creators—the artists who pour their hearts into every panel—receive only scraps. Traditional platforms like Webtoon, Tapas, and Manga Plus extract 30-50% commissions, impose 30-90 day payment delays, and restrict access based on geography. A creator in Southeast Asia might wait three months to receive 50% of what readers already paid. This isn't just unfair—it's broken.

Cryptoon was built to fix this systemic exploitation. We're a Web3 manga/webtoon reader that eliminates the middleman entirely, allowing creators to keep 100% of their earnings through direct USDC micropayments on Base blockchain. No platform fees. No payment delays. No geographic restrictions. When a reader pays $0.01 USDC for a chapter, that full amount reaches the creator's wallet in seconds—not weeks, not after deductions, but the full amount, instantly.

Our philosophy is rooted in accessibility and fairness. We implement a freemium model where early chapters are completely free for everyone—no wallet required, no barriers to entry. This ensures readers can discover new artists and stories without friction. When readers want the latest premium chapter, they pay just $0.01 USDC directly to the creator. This isn't a paywall; it's a "support wall" that empowers fans to directly sustain the artists they love.

But Cryptoon goes beyond simple payments. We've pioneered three distinct use cases for blockchain micropayments, all integrated seamlessly:

1. Direct Content Payments: Readers unlock the latest manga chapters by paying creators directly via x402 protocol. No middleman, no fees, instant settlement.

2. AI-Powered Discovery: We integrate n8n + OpenAI to provide personalized manga recommendations. Readers pay $0.01 USDC per AI query, and that payment transparently covers the real costs of running the AI service (n8n hosting + OpenAI API tokens). No hidden margins—just honest, cost-based pricing.

3. Autonomous Reading Agents: Using Coinbase AgentKit, readers can deploy AI agents that monitor their favorite series and automatically purchase new chapters when released. Set a monthly budget, pick your favorites, and never miss an update. The agent handles payments autonomously while you sleep.

What makes Cryptoon revolutionary isn't just the technology—it's the user experience. We use CDP Embedded Wallet, which means readers authenticate with email, passkeys, or social logins. No seed phrases to memorize. No browser extensions to install. No "connect wallet" confusion. It feels like Netflix, but it's powered by blockchain. Web2 simplicity with Web3 benefits.

We're not building another NFT marketplace where art becomes speculation. We're not creating token-gated communities or gamified engagement traps. Cryptoon is practical Web3: using blockchain for what it genuinely excels at—instant, borderless, zero-fee value transfer between humans. The technology serves the mission, not the other way around.

Our vision is ambitious but measurable: We want to see 10,000 independent manga artists earning a living wage directly from their readers within three years. Not 10 platforms making millions from 10,000 exploited artists, but 10,000 artists thriving on their own terms. Every $0.01 payment on Cryptoon is a vote for a creator economy that actually serves creators.

The future of content isn't owned by platforms. It's owned by the people who create it and the communities who cherish it. Cryptoon is that future, built today, on Base.

"Zero entry barriers. Instant payments. Global access. An artist in Buenos aires receives money from fans in Tokyo, with no intermediaries. Cryptoon returns what belongs to the amateur artist: 100% of your work, from day one." "Cryptoon - Your Art. Your Wallet. Your Rules."

Cryptoon is built with Next.js 14 + TypeScript for the frontend and Node.js + Express for the backend, deployed on Base Sepolia testnet.

CDP Products Integration:

• CDP Embedded Wallet (@coinbase/waas-sdk-web-react) powers Web2-style authentication
• CDP x402 Protocol facilitates HTTP 402 "Payment Required" micropayments (0.01 USDC per chapter)
• GDP AgentKit (CDP SDK v2) runs autonomous agents that monitor user favorites and auto-purchase new chapters
• CDP Faucet API provides testnet USDC distribution
• CDP Token Balances API tracks real-time wallet balances

Technical Architecture: The platform implements a hub-and-spoke model where the backend acts as an x402 facilitator. We used @statechannels browser-based wallet concepts for inspiration, though our implementation directly integrates CDP Embedded Wallet. The frontend communicates with the backend via HTTP 402 responses, triggering USDC transfers on Base Sepolia.

Notable Hack: We extended x402 beyond traditional content access to external services—using it to pay for n8n webhook calls to OpenAI for AI chat features. This demonstrates x402's versatility: backend APIs, external webhooks, and autonomous agents all using the same payment protocol. The AI chat feature lets users interact with manga characters, with each 0.01 USDC payment covering n8n hosting + OpenAI API costs.

Stack:

• Frontend: Next.js 14, TailwindCSS
• Backend: Node.js, Express
• Blockchain: Base Sepolia (Chain ID: 84532), USDC token
• AI Integration: n8n workflows + OpenAI API for recommendations and character chat
