最新报道:Coinbase's Developer Platform is launching x402, an open-source payment protocol that revives the HTTP 402 status code to enable instant, automatic payments using stablecoins like USDC for AI agents and microtransactions. The protocol, blockchain-agnostic but favoring low-fee chains like Ethereum's Base, has processed over 38,000 transactions in the past month, up 90%, with trading volume surging nearly 5,000% to over $50,000. Engineers say it could redefine internet value transfer, supporting an "agentic" economy.
