PANews reported on May 12th that, according to Decrypt, USDC issuer Circle has launched the Agent Stack toolkit, enabling AI agents to autonomously hold funds, pay fees, and trade with USDC without human intervention. Core products include an agent wallet, command-line interface, agent marketplace, and a nanopayment protocol supporting microtransactions as small as $0.000001, with no gas fees. Circle stated that traditional financial systems are designed for humans, and AI agents cannot operate autonomously, thus requiring a rebuild of the infrastructure. Circle co-founder Jeremy Allaire stated that Agent Stack is the first financial services suite to use an AI agent itself as a customer.
