Arc Mainnet Launch Event: Community and Developer Pre-Show— September 16, 2026
The Arrc Mainnet Launch Event: Community and Developer Pre-Show, was a two-hour live studio broadcast produced by Circle's community and ecosystem team to kick off Arc's mainnet launch day. Hosted by Sam Sealey, the show brought together developers, founders, Architects, and Circlers to celebrate the Arc ecosystem and make the case for Arc as the Economic OS for internet-native finance.
Across 19 segments, the show covered Arc's developer platform and App Kits, privacy features, USDC and liquidity infrastructure, the Circle Agent Stack and agentic economy, builder support programs, and the Architects community — all grounded in real products being built on Arc today.
The broadcast featured 42 guests, including 14 Circlers, 15 Arc Architects joining from 10+ countries, and 11 founder-led startups showcasing what they're building live on Arc: Pulsar, Catena, Cycles Protocol, OpenVPP, Confirmo, Ungravel, Selat, XyloNet, Synthra, Tower Exchange, and Aerodrome.
