VCN #37: Settlement — Build an x402 Paywall

Join us for VCN #37: an immersive evening dedicated to exploring the revolutionary x402 Paywall! 🌐

🔗 One agent directly pays another on-chain in a mere thirty seconds! The x402 protocol, incubated by Coinbase, is bringing life back to HTTP 402, operating seamlessly across Base, Polygon, Arbitrum, Solana, and lastly, the world wide web.

💰 The mechanics?

• EIP-3009 tokens (USDC, EURC) or Permit2.
• Enjoy 1,000 free transactions per month, and then just $0.001/tx!
• Experience lightning-fast settlement times of around 200ms.

📈 With the Bazaar marketplace boasting over 10,000 paid endpoints and hundreds of millions of transactions since May 2025, it’s time for builders to delve deep into this technology.

🎤 Format Highlights:

• Discover the thirty-line paywall in action! Express middleware demonstration: GET /weather returns 402 without payment and 200 with an X-PAYMENT header.
• Use a testnet wallet to participate. 🤑 Get free USDC from the Base Sepolia faucet for a seamless experience!

🔒 Understand the ERC-8004 identity system encompassing three crucial registries: Identity, Reputation, and Validation. This creates a trustworthy connection between agents and paywalls.

🚀 Experience the autonomous transaction loop—one agent finds an endpoint, makes the payment, and receives a response without any human intervention. By the end of the night, your endpoint could be earning USDC! (Well, testnet USDC 😉)

🛠️ This event is tailored for builders with some crypto fluency; however, don't worry if you're new! The demo flow is designed to be accessible.
