Circle Internet Group, Inc., one of the world's leading internet financial platform companies, announced the public mainnet launch of Arc, an open Layer 1 blockchain purpose-built for financial markets, real-time money movement, and agentic economic activity. Arc launches with native integration into Circle’s full-stack platform (including USDC, the world's largest regulated digital dollar, with more than $74 billion in circulation); a founding validator cohort drawn from the institutions that run global finance; more than 100 applications; and more than 100 institutional and ecosystem builders spanning global banks, asset managers, payment networks, exchanges, custodians, DeFi protocols, wallets, and AI platforms live on day one.

"Arc is the single most significant launch in Circle's history since USDC" -- Jeremy Allaire, Co-Founder, Chairman, and CEO of Circle

“Arc is the single most significant launch in Circle's history since USDC itself, and it is the embodiment of the premise we have operated on for thirteen years: money should work the way the internet works,” said Jeremy Allaire, Co-Founder, Chairman, and CEO of Circle. “USDC was step one. Arc is the network built for what comes next. The agentic economy and the onchain economy are not two different revolutions; they are the same economy seen from two sides, and both need infrastructure that never closes, settles in under a second, and is trusted by the institutions that anchor the global financial system. Today we are switching on something the world has never had before: an open, neutral, always-on economic operating system for the internet, secured by some of the most important financial institutions on Earth, and built for a world where both people and machines transact.”
