Circle Launches Arc Testnet With BlackRock, Visa, and AWS — A New Era for Onchain Finance?

Circle Internet Group (NYSE: CRCL) has launched the public testnet for Arc, its open Layer-1 blockchain designed to bring more economic activity onchain.

In a press release, Circle explains Arc is positioned as a new “Economic Operating System” for the internet, it combines predictable dollar-based fees, sub-second transaction finality, configurable privacy, and direct integration with Circle’s full-stack platform.

The network has already attracted collaboration from more than 100 institutions across global finance and technology — including BlackRock, Visa, and Amazon Web Services (AWS) — along with major capital markets, banks, and fintech players.

Developers and enterprises can now deploy, test, and build applications on Arc as Circle aims to create a unified, programmable financial infrastructure for the global economy.

Circle CEO Jeremy Allaire described Arc as “purpose-built to connect every local market to the global economy,”highlighting its mission to enable faster, more inclusive, and internet-native financial systems.

Institutions and Capital Markets Join the Testnet

Arc’s early partners include some of the world’s largest financial institutions and asset managers — among them Goldman Sachs, BNY Mellon, Société Générale, Standard Chartered, State Street, and Apollo Global Management. These participants will experiment with tokenized assets, lending, and programmable FX settlement on the network.

According to Robert Mitchnick, Global Head of Digital Assets at BlackRock, the project offers “insight into how stablecoin-denominated settlement and onchain FX could enable more efficient capital markets.”

Expanding the Onchain Payments

Beyond capital markets, Arc’s testnet features integration with global payments and fintech leaders such as Mastercard, Nuvei, Brex, Cloudflare, FIS, and dLocal. The network aims to power cross-border payments, merchant settlements, and programmable finance — including use by AI-driven autonomous agents to send, exchange, and settle value in real time.

Visa’s Head of Crypto, Cuy Sheffield, said the company is exploring how Arc’s design — integrating stablecoin-based gas fees and deterministic finality — could “help scale emerging onchain infrastructure.”

The Road to Decentralized Governance

While Circle is currently stewarding Arc’s early development, the company plans to transition toward distributed, community-driven governance. The network’s roadmap includes expanding validator participation and establishing transparent frameworks to ensure open, verifiable operations.

Ultimately, Circle envisions Arc as a shared, neutral layer of economic infrastructure — a blockchain backbone for global finance that bridges regulated institutions, fintech innovators, and decentralized networks. With major players like BlackRock, Visa, and AWS already onboard, Arc’s testnet marks a decisive step toward making onchain finance mainstream.

Price Action

Shares of Circle Internet Group Inc. (NYSE: CRCL) climbed 7.2% over the past month, closing at $143.29 on Monday amid renewed investor optimism surrounding the company’s blockchain expansion efforts.

The stock opened at $146.93, trading between a monthly low of $138.10 and a high of $147.44, with a current market capitalization of $32.95 billion. While the pre-market price shows a slight dip to $141.57 (-1.20%), Circle’s recent momentum reflects growing confidence in the company’s long-term strategy to become a core infrastructure provider for the digital asset economy.

Arc’s launch marks a strategic evolution for Circle, best known as the issuer of USDC, one of the world’s leading stablecoins. The new blockchain aims to serve as a foundation for tokenized assets, onchain payments, and programmable finance, integrating directly with Circle’s existing products and services.

Investors have interpreted the Arc testnet launch — and its backing by major financial institutions — as a signal that Circle is deepening its role in bridging traditional finance and blockchain technology.

Analysts suggest that the company’s partnerships with BNY Mellon, Goldman Sachs, and Société Générale through Arc could attract institutional liquidity and strengthen Circle’s positioning in the onchain settlement market.

The broader crypto sector has also shown signs of renewed activity, with sentiment improving after the approval of multiple digital asset ETFs and growing institutional participation in blockchain infrastructure.
