Circle launches ARC, a blockchain economic operating system built for AI agents and stablecoin payments

Circle launches ARC

Circle's Jeremy Allaire describes ARC as two and a half years in the making — a blockchain-based economic operating system designed to function as the financial infrastructure layer for the internet. Hundreds of companies launched apps and services on it at debut, including major financial infrastructure providers that run global payment networks, securities clearing, and asset management.

The platform is built AI-first. Every developer tool is AI-accessible, and Circle has built a dedicated services layer so AI agents can use ARC directly as an economic layer for transactions, contracts, and coordination. The most concrete demo at launch is "ARC agent sector," which lets an AI agent cryptographically prove the work it has done, the data it used, and how it reached its outputs. Allaire frames this as a direct answer to the black-box problem with autonomous agents — the idea that cryptographic computing networks, by their architecture, are well-suited to providing the trust and verifiability that agentic systems currently lack.

“We turned on a new global operating system today called ARC. It is an economic operating system that we've been building for two and a half years. Hundreds of companies launched their apps and services on it. It's being run by not just Circle, but many of the biggest financial infrastructure companies in the world... we've built services so that AI agents can use this themselves as an economic layer for transactions, for contracts, for coordinating.”

Payments economics

Allaire's underlying thesis on payments is that stablecoins commoditize settlement the same way the internet commoditized data transfer. USDC can move anywhere in the world, programmatically, in a fraction of a second, for a fraction of a cent. As wallet infrastructure proliferates — Cash App, Revolut, and similar platforms already connect to these networks — businesses can settle directly in digital dollars rather than routing through intermediary rails that extract basis points along the way. Allaire argues that retail-facing CEOs are acutely aware of how much margin goes to processing fees, and that ARC is purpose-built to compress that out.

The more mundane but high-volume use cases on ARC include cross-border business payments (importers in Latin America settling with Asian suppliers without intermediaries) and tokenized equities accessible to retail investors in emerging markets without a US brokerage account.

Regulatory foundation

The regulatory backdrop matters here. The Genius Act, passed into federal law with bipartisan support in both the senate and the house, makes digital dollars legal within the US financial system. The Federal Reserve, Treasury, and relevant regulators have finalized the rules. Effective January 2027, stablecoins including USDC become legal digital dollars in the US and global financial system.

A separate bill — the Crypto Clarity Act, which addressed trading venue structure and digital asset market regulation — failed to clear the senate's 60-vote threshold. Allaire's read is that this is secondary: the foundational legal status for digital dollars is already secured, and the relevant agencies (CFTC, SEC, bank regulators) will regulate market structure themselves while congress eventually catches up.

ARC's commercial launch lands with that regulatory runway now visible. The legal framework closes in four months.
