Circle Launches Arc, a New Layer-1 Blockchain for Stablecoin and Capital Market Infrastructure
Circle has officially unveiled Arc, an open Layer-1 blockchain designed to deliver enterprise-grade infrastructure for stablecoin payments, foreign exchange, and capital markets applications.
According to the announcement, Arc is EVM-compatible and uses USDC as its native gas token. The network also integrates a stablecoin FX engine, offers sub-second settlement finality, and includes optional privacy controls for enterprises that require advanced compliance features.
The blockchain will be fully integrated with Circle’s existing platform and services, while remaining interoperable with dozens of other partner blockchains supported by Circle.
This design aims to give institutions seamless access to both Arc and the broader digital asset ecosystem.
Circle highlighted that Arc’s focus is on providing high-speed, secure, and regulatory-friendly payment rails for global businesses, enabling stablecoin-powered transactions and cross-border settlements without relying on traditional financial intermediaries.
Arc’s public testnet is expected to go live later this fall, marking the first phase in its rollout before a full mainnet launch.
