Circle Launches Arc Testnet with Financial Giants BlackRock, Goldman Sachs, and Visa

October 29, 2025 , , , ,

In a significant development for the blockchain and finance industries, Circle has launched its new layer-1 blockchain testnet, named Arc, with participation from major financial powerhouses such as BlackRock, Goldman Sachs, and Visa. This initiative marks a bold step towards integrating traditional financial systems with the emerging Web3 ecosystem.

The Arc testnet is designed as a cutting-edge blockchain solution featuring dollar-based transaction fees, sub-second finality, and a seamless integration with USDC—a widely used stablecoin issued by Circle. This combination aims to pave the way for more robust and efficient financial transactions between banks, fintech companies, and Web3 developers.

By leveraging USDC’s stability and transparency, Arc seeks to bridge the gap between fiat currencies and digital assets. The introduction of dollar-based fees could potentially alleviate the volatility issues commonly associated with cryptocurrencies, thus encouraging broader adoption by traditional financial institutions.

One of the most remarkable aspects of Arc is its emphasis on speed and efficiency. With sub-second transaction finality, the blockchain is poised to transform how financial transactions are conducted, offering a level of speed that rivals existing digital payment systems. This could be particularly beneficial for high-frequency trading and other time-sensitive financial operations.

The collaboration with industry giants such as BlackRock, Goldman Sachs, and Visa further underscores the potential impact of Arc. These companies bring a wealth of expertise and resources that could help in scaling the blockchain for mainstream use. Their involvement is a testament to the growing interest and investment from traditional financial sectors into blockchain technology.

Jeremy Allaire, CEO of Circle, commented on the launch, stating, “We are thrilled to welcome our partners to the Arc testnet. This collaboration represents a significant milestone in our journey to build a more open, inclusive, and efficient financial system. Arc is designed to meet the needs of modern finance, and we are excited to see what developers and institutions will build on it.”

The Arc testnet will provide developers with a sandbox environment to experiment with and build decentralized applications (dApps) that could reshape the landscape of financial services. With native USDC integration, developers can craft dApps that offer stable, secure, and fast transactions without the typical hurdles associated with other cryptocurrencies.

As the testnet progresses, Circle plans to gather feedback from its participants to refine and enhance the platform. The ultimate goal is to transition Arc into a fully operational mainnet that could redefine how digital and traditional finance interact.

With the backing of such influential players in the financial sector, Arc could set a new standard for blockchain platforms. It embodies a future where digital currencies and blockchain technology are at the core of global finance, promoting greater accessibility, efficiency, and innovation.

The success of Arc could potentially inspire other companies to explore similar integrations, fostering a new era of collaboration between traditional finance and blockchain technology. As Circle continues to innovate, the world watches closely to see how these developments will shape the future of money and finance.
