StellarClips Whitepaper

StellarClips is a decentralized content monetization platform built on the Stellar blockchain, enabling creators to receive micro-payments for their digital content with near-zero fees and instant settlement. By leveraging Soroban smart contracts and the Stellar network's high throughput, we provide a sustainable alternative to traditional content monetization models.

1.1 Current Challenges

• Traditional payment processors charge 2-3% + fixed fees, making micro-payments uneconomical
• Content platforms take 30-50% of creator earnings
• Payment settlement can take days or weeks
• Geographic restrictions limit global monetization
• Lack of transparency in revenue distribution

1.2 Market Opportunity

The creator economy is valued at over $100 billion, with millions of creators seeking better monetization options. Micro-payments enable new business models where users pay small amounts for individual pieces of content rather than large subscriptions.

2.1 Stellar Blockchain

Stellar provides the ideal infrastructure for micro-payments with 3-5 second settlement times and fees of 0.00001 XLM (~$0.000001) per transaction. The network can handle 1000+ transactions per second, ensuring scalability.

2.2 Soroban Smart Contracts

We deploy four core smart contracts written in Rust:

• Content NFT Contract: Mints content as NFTs with metadata stored on IPFS
• Payment Contract: Handles one-time purchases and tips with automatic fee distribution
• Subscription Contract: Manages recurring subscriptions using prepaid pools
• Revenue Contract: Tracks earnings and handles withdrawals with escrow mechanisms

2.3 Off-Chain Components

• Horizon Indexer: Streams blockchain events and updates database in real-time
• IPFS Storage: Stores content files with cryptographic hash verification
• PostgreSQL Database: Caches metadata for fast queries and analytics
• Next.js Frontend: Provides responsive UI with wallet integration

3.1 Payment Flow

1. User connects Stellar wallet (Freighter, Albedo, xBull, or Rabet)
2. User selects content to purchase
3. Frontend constructs transaction calling Payment Contract
4. User signs transaction with their wallet
5. Transaction is submitted to Stellar network
6. Smart contract executes: 97.5% to creator, 2.5% platform fee
7. Horizon indexer detects event and updates database
8. Content is unlocked for user

3.2 Subscription Model

Subscriptions use a prepaid pool pattern where users deposit funds upfront. The contract automatically deducts the subscription fee at each renewal period. Users can cancel anytime and receive refunds for unused time.

3.3 Security Measures

• Non-custodial: Users maintain full control of their private keys
• Smart contract auditing and formal verification
• Content hash verification prevents tampering
• Row-level security in database
• Rate limiting on API endpoints

4.1 Fee Structure

• Platform fee: 2.5% of transaction value
• Stellar network fee: ~$0.000001 per transaction
• Creator earnings: 97.5% of transaction value

4.2 Sustainability

The 2.5% platform fee covers infrastructure costs (hosting, IPFS storage, indexing) while remaining significantly lower than traditional platforms. As transaction volume grows, economies of scale improve profitability.
