Circle’s Arc mainnet, an open, USDC-optimized layer-one blockchain designed primarily for institutional users, is scheduled to launch on Sept. 16 through a live broadcast from the company’s New York event. The program will unveil Arc and the Circle Agent Stack, while presenting on-chain infrastructure for programmable money, agent-based workflows and global financial applications. The launch comes as activity associated with Robinhood Chain has cooled and major cryptocurrencies have pulled back, prompting market participants to look to Arc for a possible next catalyst. OpenSea and fomo have announced plans to support Arc from launch, while debate continues over whether the network will accommodate crypto-native meme-coin culture. Circle co-founder Jeremy Allaire has responded positively to fomo’s launch announcement. The event will also cover institutional finance, global capital flows, always-on markets and the agent economy, with products and applications showcased for the first day. A developer preview is scheduled for Sept. 16 from 11:30 a.m. to 1:30 p.m. Eastern Time, followed by the main-stage livestream from 2 p.m. to 3:45 p.m. Representatives from BlackRock, DTCC, Aave, SBI Group, Morpho, Ripio, Extended, a16z and Circle will participate. Developers can already build on the Arc testnet before mainnet deployment.
