Stablecoins are entering a new phase. Circle has just unveiled infrastructure dedicated to AI agents capable of executing autonomous payments via USDC. Behind this announcement, a clear objective appears: to transform stablecoins into a native monetary layer of artificial intelligence.
In brief
- Circle launches the Agent Stack, a suite of tools for AI agents to manage stablecoins autonomously.
- USDC has approximately $78 billion in circulation, providing a solid foundation for this infrastructure.
- Circle wins in a global race to the financial rails for autonomous AI.
The Agent Stack: when AI meets stablecoins
On May 11, 2026, Circle unveils a suite of tools that allow AI agents to:
- hold portfolios;
- to discover services;
- to make programmable payments in stablecoins (and more precisely in USDC).
Called Agent Stack, this revolutionary infrastructure is based on several key components:
- Agent Wallets: wallets dedicated to AI agents to manage funds in complete autonomy
- Circle CLI: a command line interface for developers and AI agents
- An agentic services marketplace: for agents to discover and consume services
- A nanopayments protocol: capable of processing USDC transactions with no gas fees, starting from $0.000001 (designed for high-frequency payment flows between automated systems)
The most striking? Total autonomy, framed by strict rules
According to the press release published by Circle, the tools are designed to enable AI agents to make stablecoin payments autonomously. All in compliance with predefined permissions, spending controls and governance rules on blockchains as well as compatible payment networks.
Decryption: agents can act alone, but within a framework defined by their creators. And this is precisely what companies were asking for (autonomy, without losing control)!
USDC stablecoins: $78 billion already in circulation
Circle does not arrive empty-handed. USDC is the second stablecoin by market capitalizationwith approximately $78 billion in circulation. This weight gives Agent Stack immediate credibility. The fact is that developers don't start from scratch. They rely on a liquid, regulated and already massively adopted infrastructure.
Especially since Circle is not alone in this area. In March, MoonPay launched a open source wallet standard for AI agents. For its part, BitGo has deployed a tool allowing agents to access wallet resources via natural language instructions. Visa and Stripe have also introduced tools dedicated to AI-driven payments.
With the Agent Stack, Circle nevertheless positions itself as the reference infrastructure of this emerging agentic economy.
One thing is certain: stablecoins are no longer just a value transfer tool. They become the fuel for a new economic layer, that of autonomous AI agents. And Circle has just laid the first foundations of this infrastructure.
