CoinWorld News reports that Coinbase's AI-focused payment protocol x402 is progressing toward becoming an open, standardized infrastructure under the Linux Foundation, aiming to create a community-governed ecosystem for high-frequency microtransactions that are difficult for traditional financial systems to process efficiently. The protocol has established its first governance organization—the x402 Foundation, with members including Cloudflare, Stripe, and support from other industry giants. x402 can handle high-frequency transactions worth only a fraction of a cent, making it suitable for AI agents to autonomously execute "agent payments," and it has become a popular solution in the micro-payment sector of the cryptocurrency industry.
