Our platform revolutionizes digital advertising by combining Web3's transparency and fair revenue distribution with Web2's lightning-fast user experience. We solve the critical problem of slow, friction-heavy Web3 applications that require wallets for every interaction.The Problem: Traditional Web3 ad platforms are slow (3-5 second load times), require wallets for viewers, and create terrible user experiences that kill adoption.Our Solution: A hybrid architecture that delivers ads in under 200ms while maintaining full blockchain transparency and decentralization.Key Features:

Zero Friction for Viewers: No wallets needed, ads load instantly like traditional web ads Dual Campaign Types: CPM (cost per 1000 impressions) and CPC (cost per click) with real-time optimization 30-Second Publisher Integration: Copy-paste one script tag to start earning 2-Minute Advertiser Onboarding: Upload creative, set budget, launch campaign Instant Withdrawals: Publishers can withdraw earnings anytime with one MetaMask transaction Real-Time Analytics: Live dashboards showing impressions, clicks, earnings, and performance metrics Transparent Payments: All transactions verifiable on-chain with detailed breakdowns User Experience:

Advertisers create campaigns in under 2 minutes with intuitive dashboards Publishers integrate with a single line of code and see earnings update live Website visitors see ads instantly without any blockchain interaction All parties benefit from reduced fees (60-70% less than Google AdSense) and transparent, automated payments This isn't just a demo—it's a production-ready platform that makes Web3 advertising accessible to mainstream users while preserving the benefits of decentralization.

Architecture: We built a sophisticated hybrid system that combines the best of Web2 performance with Web3 transparency. Core Technologies:

Smart Contracts (Solidity on Polygon): Handle campaign management, payment distribution, and batch verification to minimize gas costs Backend API (Node.js/Express): Manages high-speed impression logging, CDN synchronization, and blockchain batch processing Database (PostgreSQL): Stores impressions/clicks for instant analytics while batching to blockchain every 100 events IPFS + CDN Hybrid: Ad creatives stored permanently on IPFS, automatically synced to Cloudflare CDN for <200ms delivery Frontend (React/Next.js): Responsive dashboards for advertisers and publishers with real-time WebSocket updates

The Hacky (But Brilliant) Parts:

Batch Processing Innovation: Instead of expensive per-impression blockchain transactions, we aggregate 100 impressions into single transactions, reducing gas costs by 90% while maintaining security through cryptographic batch verification. CDN-IPFS Sync: We automatically mirror IPFS content to traditional CDNs, giving us decentralized storage with centralized speed. When advertisers upload to IPFS, our backend immediately pulls and caches to Cloudflare. Wallet-Free Viewing: The breakthrough insight—viewers never interact with blockchain. Only advertisers (paying) and publishers (earning) need wallets. This eliminates the biggest Web3 UX barrier. Real-Time Off-Chain Analytics: We provide instant dashboard updates using WebSockets and database queries, while blockchain provides the source of truth for payments. Best of both worlds.

Partner Technologies:

Polygon: Low gas fees enable our batch processing economics IPFS: Decentralized storage prevents ad censorship Cloudflare: CDN ensures global <200ms ad delivery MetaMask: Seamless wallet integration for campaigns and withdrawals
