Circle, the issuer of USDC, is launching its own Layer 1 blockchain called Arc to address challenges in the stablecoin industry, particularly as interest rate cuts threaten its revenue model. Arc is designed for enterprise cross-border payments using stablecoins, offering sub-second finality, configurable privacy options, and transaction fees paid in USDC to avoid crypto volatility. It aims to reduce reliance on interest income and expand distribution channels. Despite partnerships with major firms like BlackRock and Visa, Arc faces competition from Tether and Stripe's Tempo, as well as challenges in attracting liquidity and regulatory scrutiny over privacy features. Circle's established reputation and payment network provide a competitive advantage, but the success of Arc is critical amid a shifting economic landscape.

Why Top Institutions Are Betting Big on New Blockchains Like Arc, Canton, and Tempo This week saw a surge of major funding announcements for new, purpose-built blockchains. Circle's Arc raised $222M at a $3B valuation from investors like BlackRock. Canton Network developer Digital Asset secured $300M led by a16z at a $2B valuation. Stripe's Tempo, already a leader, raised $500M last year and has partnered with major firms. These three chains share key traits: they are designed for stablecoins and asset tokenization, they emerged after the US passed the *Genius Act* in July 2025, they natively support private transactions crucial for enterprise adoption, and they are backed by traditional finance and tech giants—unlike the crypto-native origins of Ethereum or Solana. This trend highlights three major shifts: 1) Clear regulation (like the pending *Clarity Act*) is unlocking massive institutional capital. 2) Built-in privacy is becoming a core feature for real-world business use, addressing the limitations of fully transparent ledgers. 3) Established corporations are now directly entering the blockchain arena, bringing significant resources and execution capability, which will accelerate innovation and competition across the entire crypto ecosystem.

Circle, the issuer of USDC, announced that its new public blockchain Arc completed a $222 million private sale for its native token ARC, with the network's fully diluted valuation reaching $3 billion. The funding round was led by a16z crypto, with participation from major institutions including BlackRock, Apollo, and ICE. The article explains Circle's rationale for building its own L1 blockchain, Arc. Existing chains like Ethereum and Solana are seen as lacking native support for large-scale institutional needs, such as regulatory compliance, predictable transaction costs, and asset issuance/redemption workflows. Arc is designed to fill this gap as a foundational layer for the on-chain economy, moving beyond Circle's reliance on USDC reserve interest for revenue. It details the dual-token model of Arc: USDC serves as the stable gas token for predictable transactions, while ARC is the network's native asset used for staking in the planned transition to Proof-of-Stake, governance, and aligning long-term incentives among participants. ARC's total supply is 10 billion, with 60% allocated to ecosystem development, 25% to Circle, and 15% to a long-term reserve. All protocol fees are converted to ARC, with portions burned and distributed to stakers. The piece contrasts the value proposition of Circle's public stock (CRCL) and the ARC token. CRCL captures the company's core cash flows from USDC interest and other business lines. ARC captures the growth potential of the Arc network itself. While legally separate, network success benefits both: it drives USDC usage for Circle and increases the value of its 25% ARC holding. Finally, it outlines participation avenues for retail users, primarily through the Arc House community and testnet activities, while noting the competitive landscape with projects like Canton Network and Plasma. The article concludes that Arc's success hinges on attracting real institutional activity post-mainnet launch, scheduled for Summer 2026.

Circle Announces $222 Million Funding for Arc Network's Native Token ARC. With USDC circulation reaching $77 billion, growing 28% year-over-year, Circle is building its own Layer 1 blockchain, Arc, to address unmet institutional needs like compliance, privacy, and predictable transaction costs. While USDC serves as Arc's gas token for stable payments, the newly issued ARC token is designed for network security (staking in the future PoS system) and governance, creating long-term alignment among participants. Circle (stock CRCL) retains its core revenue from USDC reserve interest and other business lines, plus holds 25% of ARC's total 10 billion supply, which will capture value from network fees. Arc's testnet is live ahead of a mainnet launch planned for Summer 2026. The funding round, led by a16z crypto with participation from BlackRock and others, values the network at $3 billion FDV. The article notes a competitive landscape with projects like Canton Network and Plasma, and advises that ARC's long-term value depends on real adoption and fee generation to offset its 2-3% annual inflation.

Circle raised $222 million for its proprietary Layer-1 blockchain, Arc, positioning itself not just as a stablecoin issuer but as the owner of the settlement infrastructure USDC relies on. This move, backed by investors like BlackRock and Apollo, highlights a significant structural conflict unaddressed by the GENIUS Act of 2025. While the act focuses on stablecoin reserves and issuer oversight, it remains silent on the market structure implications of an issuer controlling the underlying network—a scenario akin to a currency issuer also owning the payment rails. Traditionally, financial regulations separate issuers from settlement infrastructure to ensure neutrality. With Arc, Circle gains control over transaction ordering, fees, and network rules, potentially favoring USDC over competitors. The article argues that this creates a permanent structural temptation, even if no abuse occurs. The solution lies in applying established market infrastructure principles: mandating neutral transaction ordering, transparent fee schedules, and governance separated from Circle’s commercial interests. The current pre-mainnet phase offers a critical window for regulators to establish these rules before Arc becomes entrenched. Once operational, enforcing changes would be costly and disruptive. The core question remains: should a regulated stablecoin issuer be allowed to own the settlement network its competitors must use? The GENIUS Act doesn’t answer this, but Circle’s Arc strategy makes it urgent.
