Arc is an open Layer-1 blockchain purpose-built to unite programmable money and onchain innovation with real-world economic activity. Designed to serve as the Economic OS for the internet, Arc enables builders and issuers worldwide to power the next era of onchain lending, capital markets, FX, and payments, igniting liquidity across currencies and asset classes. Engineered for mass adoption, Arc is enterprise-grade infrastructure featuring predictable fiat-based fees using stablecoins as gas (starting with USDC), deterministic sub-second finality, opt-in configurable privacy, and direct integration with Circle’s full-stack platform for secure access to liquidity and powerful developer tooling. As a public EVM-compatible network, developers can deploy smart contracts, build applications, and transact freely using familiar tools. While validator participation is permissioned for security and compliance, access to Arc is fully open.

Core principles

Arc is more than a new blockchain. It’s a new approach to how global economic coordination and infrastructure should be built, forged with the same principles of transparency and trust that define Circle:
Arc focuses on real-world economic activity, including but not limited to global finance, internet commerce, and institutional-grade DeFi.
While enterprise-ready, Arc is a public network and open to all developers. Anyone can build, transact, integrate, and contribute to the Arc ecosystem.
Arc is interoperable with the broader multichain ecosystem through Circle CCTP and Circle Gateway, unlocking new use cases, partners, and institutional liquidity onchain.
Arc aligns builders and partners across exchanges, market makers, asset issuers, fintechs, banks, PSPs, and enterprises to achieve something bigger than the sum of their parts.
Arc is built on Malachite, a highly efficient BFT consensus engine designed for certainty, reliability, and long-term operational excellence.
