ViaBTC CEO Haipo Yang: From Nof1 to x402 — A Look at AI Agent Applications and What’s Next

Haipo Yang, CEO of ViaBTC, explains that the x402 protocol standardizes on-chain payments as a web service, using a Facilitator to manage trust and execution, which is crucial for AI Agents that require high-frequency, low-cost micropayments that traditional systems like Visa cannot efficiently handle due to high friction and entry barriers.

The long-term value of x402 lies in Agent-to-Agent economic networks, enabling invisible payments where Agents automatically consume services (like API calls) and settle fees via automated micropayments, shifting API monetization to true pay-as-you-go usage. A security advantage is enforcing spending limits via token wallets, unlike the unlimited liability of credit cards. However, reliance on Facilitators introduces centralization risks and the protocol lacks features for real-world commerce like refunds.

Currently, AI Agents deliver value primarily to developers through pair programming and enabling non-technical users via "vibe coding." Looking ahead, the biggest opportunity is autonomous collaboration and procurement. Initiatives like Nof1's trading competition and the Model Context Protocol (MCP) support Agents in forming closed loops of perception and action, enabling automated trading and market making, with x402 serving as the economic rail for this complex, cooperating digital economic system.
