A New Economic Operating System for the Internet Opens with Over 100 Launch and Design Participants

Circle Internet Group, Inc. (CRCL:NYSE) (Circle) today announced the launch of the public testnet for Arc, an open Layer-1 blockchain network designed to meet the needs of developers and companies bringing more economic activity onchain. The launch arrives with broad-based engagement and collaboration from more than one hundred companies across the financial and economic system, deep infrastructure support, and global participation. Arc is now available for developers and enterprises to deploy, test and build on what Circle describes as the new Economic Operating System (“OS”) for the internet.

Arc represents a major step forward in building open, programmable financial infrastructure for the global economy. Featuring predictable dollar-based fees, sub-second transaction finality, opt-in configurable privacy, and direct integration with Circle’s full-stack platform, Arc enables a wide range of use cases across lending, capital markets, foreign exchange (FX), and global payments.

“With Arc’s public testnet, we’re seeing remarkable early momentum as leading companies, protocols, and projects begin to build and test. Combined, these companies reach billions of users, move, exchange, and custody hundreds of trillions in assets and payments, and support local economies across Africa, the Americas, Asia, Europe, and the Middle East. This geographic diversity highlights a defining strength of Arc: its purpose-built to connect every local market to the global economy,” said Jeremy Allaire, Co-Founder, Chairman and CEO of Circle. “Arc presents the opportunity for every type of company to build on enterprise-grade network infrastructure—advancing a shared vision that a more open, inclusive, and efficient global economic system can be built natively on the internet.”

The Path to Distributed Governance

The launch of Arc’s public testnet marks the beginning of a network designed to evolve into a distributed, community-driven system.

This progression will include expanding validator participation, establishing transparent and verifiable governance frameworks, and enabling community involvement in network evolution. The goal for Arc is to become the shared, neutral layer of economic infrastructure for the internet — open, cryptographically accountable, and collectively operated.
