Circle's Arc Blockchain Launches with 100+ Partners Building Internet Financial Infrastructure
Circle's Arc Blockchain Launches with 100+ Partners Building Internet Financial Infrastructure
🏗️ Circle's new blockchain
Circle has unveiled Arc, a new blockchain network designed as infrastructure for the emerging Internet Financial System. The platform goes beyond stablecoins to create a unified layer connecting regulated digital assets, applications, and institutions.
Key Technical Features:
- Deterministic ~1 second finality for fast settlement
- Transaction fees denominated in USDC for predictable costs
- Built specifically for institutional and AI-native financial workflows
Early Traction: Over 100 partners are already building and testing on the network, signaling institutional interest in the infrastructure layer.
Strategic Context: Arc represents Circle's evolution from stablecoin issuer to full-stack financial infrastructure provider. The platform aims to serve as the "Economic OS for the internet," uniting programmable money with real-world economic activity. This follows USDC processing nearly $10T in onchain transaction volume in Q3 2025 and expanding to 30 blockchains.
The launch comes as regulatory clarity has accelerated institutional adoption of digital assets across payments, treasury, and capital markets.
The internet financial system isn’t built with a single product. It’s built with layers that reinforce each other. → Trusted digital assets power value. → Applications turn that value into real workflows. → @Arc unites programmable money and onchain innovation with real-world

Building the infrastructure behind internet-native financial systems requires trust, scale, and time. @jerallaire joined @DM_Rubenstein at @TheEconomicClub to discuss Circle’s work on stablecoin rails and the foundations of global money movement.
Arc represents a shift beyond stablecoins alone. As finance and economic coordination move onto the internet, Arc provides the infrastructure layer that connects regulated stablecoins, applications, and institutions into a single system. → Deterministic ~1s finality →
For users and institutions, the promise is simple: faster, cheaper, always-on finance. But regulated stablecoins are just the beginning. A new system is taking shape. → @Arc, a new blockchain network designed as the Economic OS for the internet → Regulated digital assets
Arc was designed in 2025 to become the Economic OS for the internet. → Designed for deterministic sub-second finality → @USDC as native gas with predictable, fiat-denominated fees → Built for institutions, developers, and AI-native financial workflows → Backed by a growing
Circle’s Chief Strategy Officer @ddisparte shares, “USDC is emerging as the tokenized dollar backbone of the modern financial system,” in conversation with @scottmelker.

Beyond stablecoins, a new financial system is taking shape. What began as an innovation in digital dollars has evolved into core financial infrastructure. In just a few years, regulatory clarity, institutional adoption, and onchain technology have converged. This report
A wave of commercial expansion took shape in 2025. As regulatory clarity advanced, institutions moved from exploring stablecoins to using them in real financial workflows. @USDC, EURC, and USYC began showing up across payments, treasury, settlement, and capital markets. What
USDC’s multichain expansion accelerated in 2025. → Natively available on 30 blockchains → 14 new networks added in a single year → Built to meet institutional scale and reliability requirements The goal wasn’t just reach. It was usability. CCTP, Gateway, and xReserve work
How can stablecoins expand financial access for the world’s most underserved? Circle’s Chief Strategic Engagement Officer, Elisabeth Carpenter, shared her perspective with the World Economic Forum, exploring how regulated stablecoins are already being used to widen access to
Stablecoins are emerging as foundational building blocks in the broader tokenization of real world assets. @ddisparte speaks on USDC becoming the onchain dollar infrastructure of the modern financial system with @scottmelker on The Wolf Of All Streets.
Capital markets are moving onchain. → 3x YoY growth in @USDC share of spot trading volume as of Sep 30, 2025 → Stablecoins powering settlement and market liquidity → 24/7 markets beyond legacy banking hours What was once conceptual is taking flight.
At @wef, @jerallaire discussed the growing role of stablecoins in the global financial system on a panel moderated by @gerardtbaker. As stablecoin transfers surpass traditional transfers, the focus has shifted from experimentation to infrastructure reshaping payments,
Trust is the foundation of any financial system. As regulatory clarity accelerated in 2025, institutions increasingly looked for digital assets that could operate inside clear, enforceable rules. Circle was already built for that environment, with fully reserved stablecoins,
As billions of AI agents enter the global economy, the financial system must operate at internet speed and scale. At @wef, @jerallaire on why stablecoins are the only infrastructure built for that future.
Circle Integrates AI Across Product Development, Sees Real Acceleration
Circle is integrating AI throughout its product development, engineering, and deployment processes, reporting tangible acceleration in product velocity. This follows recent statements from CEO Jeremy Allaire about building internet financial infrastructure at the intersection of AI, stablecoins, and blockchains. The company anticipates AI agents will drive exponential growth and dramatically increase the velocity of money through autonomous transactions. Circle positions itself as creating the foundational economic infrastructure needed for this emerging era of AI-driven commerce.
Circle Enables AI Agents to Execute Autonomous Cross-Chain USDC Transactions
Circle is building infrastructure for AI agents to autonomously conduct cross-chain USDC transactions at near-zero cost through Circle Gateway capabilities. **Key developments:** - AI agents can now execute autonomous transactions using USDC across different blockchains - Circle Gateway enables these cross-chain operations with minimal fees - The company hosted an agent-only hackathon to advance development - Circle joined the [Agentic AI Foundation](https://aaif.io/press/agentic-ai-foundation-welcomes-97-new-members-as-demand-for-open-collaborative-agent-standardization-increases/?utm_content=370951859&utm_medium=social&utm_source=linkedin&hss_channel=lcp-111268938) to support open standards **Technical approach:** Circle is integrating Gateway with x402, an open payment protocol designed for agent transactions. The company is also working with Google on Agent2Agent (A2A) and contributing to the Agent Payments Protocol (AP2). The infrastructure aims to create new monetization models by enabling machine-to-machine micropayments using programmable, internet-native money that can move globally in real time.
Cross-Chain Transfer Protocol Enables Seamless Movement of Tokenized Assets
**Infrastructure development is advancing cross-chain capabilities** The Cross-Chain Transfer Protocol (CCTP) is being positioned as foundational infrastructure for moving tokenized assets between different blockchains. The protocol aims to enable: - Tokenized stocks and investment funds - Bank deposits - Stablecoins These assets can now transfer across different blockchain networks without friction. The development represents progress in blockchain interoperability—the ability for separate networks to communicate and exchange value. **Technical context** Previous work on blockchain interoperability, including Chainlink's Cross-Chain Interoperability Protocol (CCIP), has focused on allowing data and assets to flow between chains. The current CCTP development builds on these earlier efforts to create what developers describe as "highways for value movement." The protocol addresses a longstanding challenge in blockchain technology: isolated networks that couldn't easily exchange assets or information.
Circle Launches USDCx Stablecoin on Cardano via xReserve
Circle has launched **USDCx** on Cardano through its xReserve platform, bringing cross-chain USDC liquidity to the network. **What is USDCx?** - A stablecoin backed 1:1 by USDC held in Circle's xReserve - Enables payments, lending, trading, borrowing, and liquidity provision - Works without third-party bridges for trust-minimized transfers **Launch Partners** Three Cardano DeFi applications support USDCx at launch: Liqwid Finance, Minswap, and SundaeSwap. **Early Adopter Incentive** IOG is covering all bridging costs from USDC to USDCx for the first 10 days, removing fees for early users.
