Arc Mainnet is live. Now look up.
Tonight, 850 drones will illuminate the San Francisco skyline above the Ferry Building, telling the story of Arc, the Economic OS for the internet.
The show points to what comes next: up to $1M for eligible teams building on Arc.
Fast settlement. USDC-powered transactions. Agentic payments. Builders around the world.
Watch live on X tonight.

Arc Mainnet is live. The foundation is here.
Institutions, founders, developers, and builders now have a new platform for real-world finance.
What gets built next starts here.
The ARC token has been minted.
Circle is the first publicly traded company to mint a network token for a new blockchain.
This is a technical milestone in the Arc roadmap as the network explores a future transition from Proof of Authority toward Proof of Stake.
The minting of ARC does not represent any commitment to a public launch of the token.
ARC is not live, tradeable, available for public use, or active for staking, governance, fees, or utility. The Arc network remains Proof of Authority today. Future ARC functionality and activation remain subject to change.
