Arc Network Arc Network

Arc is an open EVM-compatible Layer-1 blockchain designed to serve as the "Economic OS" for the internet. It connects onchain innovation with real-world economic activity, enabling applications in lending, capital markets, FX, and payments. Built for enterprise-grade performance, Arc offers stablecoin-based gas fees (starting with USDC), sub-second finality, optional privacy, and direct integration with Circle’s platform. While validator participation is permissioned for security, the network remains fully open to developers and users.
