Circle is bringing its full AI payments playbook to San Francisco this week, presenting the Circle Agent Stack at the AI Engineer World’s Fair running from June 29 to July 2. The suite of tools, launched back in May, is designed to let autonomous AI agents hold assets, find services, and settle payments in USDC, all without a human clicking “confirm.”
What the Agent Stack actually does
The Circle Agent Stack bundles several components into a single developer-facing toolkit. There’s the Circle CLI for command-line interaction, Agent Wallets for giving AI agents their own on-chain accounts, and an Agent Marketplace where agents can discover and transact with each other.
The headline feature is the Nanopayments function powered by the Circle Gateway. It enables gas-free USDC transfers as small as $0.000001. For context, that’s one-thousandth of a cent.
The entire stack runs on USDC across multiple blockchains, providing what Circle describes as cross-chain composability and machine-speed transaction flows.
