X4PN VPN: Decentralized VPN. Pay $0.10/min USDC, earn X4PN tokens. Polygon + WireGuard + x402. 3-project MVP ready. 200K MAU → $500K/mo in 6mo.
X4PN VPN replaces wasteful VPN subscriptions with pay-per-minute micropayments using x402 protocol on Polygon. Users deposit USDC, connect to WireGuard nodes, and auto-settle every 60 seconds. Everyone earns X4PN tokens—users via light node verification, operators via bandwidth.
textTraditional VPNs: ❌ $13/month → Lose money Mysterium: ❌ MYST token crash → Network dies X4PN: ✅ USDC payments + X4PN rewards → Sustainable forever
x402 enables real-time HTTP-native settlements, fixing DePIN's payment problem.
text✅ Smart Contracts: USDC vault + session lifecycle + rewards ✅ Node Agent: WireGuard + x402 settlement + API ✅ Chrome Extension: MetaMask + server list + connect flow ✅ End-to-End: Deposit → VPN → Auto-settle → Earnings ✅ Testnet: Polygon Mumbai (verified contracts)
textUser pays: $0.10/min USDC ├─ Node: $0.08 (80%) └─ Protocol: $0.02 (20%) → Dev, servers, marketing 10K users × 30min/mo = $30K revenue 100K users = $300K/mo (profitable)
