Circle unveils Interop stack for $110B USDC network. Published on: April 10, 2026 Kathleen Kinder Barry Elad As Featured In Circle has introduced a full interoperability stack aimed at scaling its $110 billion USDC crosschain network and expanding support beyond stablecoins. Key takeaways. * Circle CCTP has processed over $110 billion in USDC transfers across 20+ blockchains since 2023. * Circle Gateway reached $400 million monthly volume with near instant crosschain settlement. * Interop expansion will support EURC, USYC, cirBTC and third party assets. * New developer tools aim to simplify crosschain transactions and workflows. What happened? Circle announced a major upgrade to its crosschain infrastructure, positioning its interoperability stack as a foundation for the growing internet financial system. The update expands capabilities beyond USDC and introduces faster settlement, broader asset support, and simplified developer tools. Circle expands beyond USDC. Circle is moving beyond its core stablecoin by extending its Cross Chain Transfer Protocol to support multiple digital assets. The expansion will include EURC, USYC, and cirBTC, along with third party assets issued through its platform. This shift addresses a major challenge in crypto today, liquidity fragmentation across blockchains. Asset issuers often struggle to distribute tokens efficiently across ecosystems. With the new model, assets can be issued on Arc, Circle's institutional focused blockchain, and distributed across more than 20 chains from a single control point. Arc is designed to act as a liquidity hub, offering sub second settlement, predictable fees paid in stablecoins, and a globally distributed validator network. Circle describes it as a coordination layer for asset issuance and liquidity routing. Gateway growth signals rising demand. Circle Gateway is emerging as a key part of this ecosystem. The service allows businesses to hold a unified USDC balance accessible across multiple chains in under 500 milliseconds. * Gateway processed $400 million in March 2026. * April volume had already reached $230 million within the first nine days. This rapid growth highlights increasing demand for instant crosschain liquidity. Instead of pre positioning capital across chains, businesses can now access funds wherever needed in real time. Gateway also introduces nanopayments, enabling gas free USDC transfers as small as $0.000001. This opens the door to new use cases such as AI driven transactions, pay per request APIs, and micro content payments. Faster settlement and better capital efficiency. Circle is also tackling one of the biggest bottlenecks in crosschain activity, slow and inconsistent settlement times. With its new fast transfer capability, developers can enable crosschain USDC transactions that settle in seconds without waiting for source chain finality. This improves: * Capital efficiency by reducing idle funds. * User experience with faster transaction completion. * Predictability for businesses operating across chains. Together with Gateway, this creates a system where liquidity is not locked or delayed, but instead moves seamlessly across ecosystems. Developer tools simplify crosschain complexity. To reduce friction for developers, Circle introduced a suite of orchestration tools designed to make crosschain applications easier to build and manage. Key tools include: * Bridge Kit for integrating crosschain flows with simple SDK methods. * Deposit Kit for one click crosschain deposits, currently in development. * Circle Fee Service to bundle all transaction fees into a single upfront quote. * Circle Workflows to coordinate multi step crosschain actions as one unified process. These tools aim to replace complex, fragile transaction sequences with simpler and more reliable workflows. Circle also announced USDC Bridge, a consumer facing app that allows individuals to transfer USDC across chains without relying on third party bridges. Unlocking new use cases across the ecosystem. The expanded interoperability stack is already supporting real world applications. * Hyperliquid has integrated crosschain USDC funding to simplify user onboarding. * RockawayX uses Gateway to reduce liquidity fragmentation. * OpenMind is testing nanopayments for AI agent to agent transactions. These early use cases show how crosschain infrastructure can support high frequency, low value transactions and emerging autonomous economic systems. What this means for the market? Circle is positioning itself as more than just a stablecoin issuer. With this interoperability stack, it aims to become the core infrastructure layer for moving digital assets across blockchains. The broader vision mirrors how standardized protocols enabled the internet to scale. Circle is betting that crosschain interoperability will play a similar role in shaping the future of finance. For institutions and developers, the benefits are clear: * Faster settlement times * Lower capital requirements * Seamless multichain asset access The full expansion of CCTP is expected later in 2026, with Circle actively seeking feedback from developers and asset issuers building crosschain solutions. CoinLaw's takeaway. I see this as a big step toward making crypto actually usable at scale. In my experience, crosschain complexity has always been one of the biggest barriers for both developers and users. What Circle is doing here feels like building the backend plumbing that most people never see but everyone depends on. I found the move beyond USDC especially important. If Circle can bring the same level of interoperability to real world assets, it could unlock a much bigger market than stablecoins alone. The real impact will depend on adoption, but this direction makes a lot of sense for where the industry is heading. This article has been reviewed and fact-checked by Barry Elad.

Circle defends USDC freeze policy after Drift exploit, calls for faster legal frameworks. Circle has defended its USDC freeze policy, arguing that legal constraints - not inaction - limit how quickly it can respond. Updated 11:03 EDT April 10, 2026 Circle has responded to recent criticism over its handling of illicit fund flows. It argues that it cannot freeze assets without legal authorization, following scrutiny tied to the Drift Protocol exploit. In a blog post published on 10 April, the company said its ability to freeze USDC is "not discretionary," but instead depends on lawful orders from relevant authorities. The statement comes days after an on-chain report alleged more than $420 million in compliance lapses linked to delayed or absent freezes. "Freezing is a legal obligation, not a discretionary tool" Circle pushed back on the idea that it can act unilaterally to block funds, stating that USDC operates within U.S. and European regulatory frameworks. According to the company, freezing assets requires a formal legal process. Also, acting outside those constraints could undermine property rights and financial privacy. The distinction is central to its response: while the technology enables blacklisting, Circle maintains that the decision to act must come from law enforcement or the courts, not the issuer itself. Drift exploit brought response times into focus. The clarification follows criticism tied to the 1 April exploit of Drift Protocol, during which over $270 million was reportedly drained. Reports claimed that more than $230 million in USDC was bridged across chains during the incident without being frozen. The event raised questions about how quickly issuers can respond in fast-moving exploit scenarios. The report also cited past incidents - including Cetus, Mango Markets, and Nomad - where USDC-linked funds were allegedly frozen late or not at all. Circle's response does not directly address specific cases. Instead, it reframes the issue as a legal constraint rather than an operational failure. A gap between technology and law. A key theme in Circle's statement is what it describes as a mismatch between the speed of blockchain activity and the pace of legal processes. While tools exist to intervene quickly, the company argues that current regulatory frameworks do not allow for rapid, coordinated action without due process. This, it says, creates a structural gap that can be exploited by bad actors moving funds across chains in real time. Policy push gains momentum. Circle explicitly linked the issue to ongoing regulatory efforts in the United States, including the GENIUS Act and the CLARITY Act. The company called for updated legal frameworks that would enable faster intervention while preserving due process, privacy, and property rights. The timing is notable. Recent signals from U.S. officials, alongside a White House report challenging restrictions on stablecoin yield, suggest growing alignment within the executive branch on digital asset policy. Final summary. * Circle says it cannot freeze USDC without legal orders, pushing back against criticism following the Drift exploit. * The company is calling for faster legal frameworks, linking enforcement challenges to ongoing U.S. regulatory efforts.

Circle has partnered with Polymarket as the prediction market overhauls its exchange infrastructure over the next two to three weeks. The platform is introducing new smart contracts, a redesigned order book and Polymarket USD, a settlement token backed 1:1 by Circle's USDC. Circle earns revenue from interest generated by dollar reserves backing USDC. Mizuho analyst Dan Dolev estimated Polymarket's 2026 trading volumes may reach $50 billion annually, potentially increasing USDC's market cap by 25% or more. Polymarket implemented taker fees across nearly all categories on 30 March. The partnership comes alongside Circle's broader product expansion, including cirBTC launched on 2 April and its quantum-resistant Layer-1 blockchain Arc, expected to debut in late 2026.
