Circle Agent Stack Is Here: The Era of AI Agents Managing Their Own Wallets and Paying in USDC
Circle releases Agent Stack with four tools - Agent Wallets, Marketplace, CLI, and Nanopayments - enabling AI Agents to autonomously hold USDC and complete payments. The x402 protocol allows Agents to automatically sign payments when APIs request payment, then receive data after on-chain settlement, fully automating micro-payments.
