Circle

Arc Public Testnet is live. @Arc is an open Layer-1 blockchain designed to serve as the Economic OS for the internet, uniting programmable money and onchain innovation with real-world economic activity. Arc is uniquely suited to be a new trusted foundation for: → Lending and financial services → Capital markets → Tokenized asset issuance → Stablecoin settlement worldwide With deterministic sub-second finality, stablecoins as native gas, and opt-in configurable privacy, Arc is purpose-built to meet the needs of the global financial system. It’s built for a world where: → Financial apps are as accessible as email → Dollars, euros, pesos, and other fiat currencies move instantly → Private transactions that support compliance happen at scale → AI agents transact and coordinate commercial activity autonomously Arc testnet is already seeing participation from leading companies across capital markets, global payments and technology platforms, and full-stack developer infrastructure providers. Guided by Circle’s vision of making money truly open and programmable, Arc is public internet infrastructure that invites everyone to build, coordinate, and transact onchain.

Stablecoins are rewiring the global economy, and the world's largest banks are on the front lines.

1️⃣ @Circle’s USYC expanded to BNB Chain in July 2025. $2B+ supply lives on BNB Chain in just 9 months, making up 93% of its total supply. Higher and higher. Source: @RWA_xyz

Circle Current: Banking on Stablecoins We brought senior banking leaders together in NYC to discuss what’s actually changing inside financial institutions. What stood out most: for banks, stablecoins are not a technology experiment. → Regulation is shaping, not slowing, adoption → Always-on settlement is moving closer to legacy infrastructure → Tokenized money is shifting from pilots to production planning → Stablecoins are being embraced as real payment rails What stood out most: for banks, stablecoins are not a technology experiment. They’re an infrastructure and competitive positioning decision. The new internet financial system is being built in real time.

Circle Alliance Program member @PEXX_Official is integrating USDC into global treasury and payout workflows. By using stablecoins for settlement across emerging markets, PEXX supports faster, more efficient cross-border money movement. circle.com/alliance-progr…

@GustoHQ 👋

Same-day payments for international contractors are now live in Gusto. Wise Account or USDC stablecoin - contractors pick what works for them. Employers pay the same way they always have.

.@UKHouseofLords invited me to testify today in a far-reaching hearing on the regulation of stablecoins. The UK has a distinct "second mover" advantage to borrow the best of MiCA and the GENIUS Act - the time to act is now lest competitiveness wanes. circle.com/blog/circles-d…

Building the future of programmable money takes real builders shipping real systems. We’re excited to announce the first cohort of 2026 Circle Developer Grant recipients: @AgriDexPlatform @BeeezoHive @BlockradarHQ @BuFi_Global @CashmereLabs @ArrelTechnology (DAPL - Digital Asset Platform) @dzap_io @flezpay @gcrx_io @HurupayApp @myazahq @OpenVPP @payritHQ @rebelfi_io @usesfxmoneyapp @thurmanlabs @TidesHQ @trumarket_tech This group stood out for technical depth, execution velocity, and clear paths to production across: → AI financial agents → Payments & treasury → Capital markets & FX → DeFi & liquidity → Real-world assets Many are already integrating Wallets, Gateway, and CCTP, with early Arc experimentation underway. We’re proud to back teams that are already demonstrating real-world utility on stablecoin infrastructure. Beyond funding, we’ll work closely with these founders as they build—offering resources, guidance, and hands-on support as they integrate Circle products like Wallets, Gateway, and CCTP (with Arc on their roadmap).

Last year, Circle Foundation was created to advance financial resilience and inclusion worldwide. Hear from Elisabeth Carpenter on our first international grant in support of the @UN.

@henloitsjoyce @arc @crossmint @xmtp_ All eyes on Circle 👋

V3 OF THE AGENTIC FINANCE MARKET MAP There were way too many new services, wallets, and apps that I found over the weekend. If we keep growing I'm gonna have to make a map for each separate category. See below for new players ⬇️

Nanopayments are not “small payments.” They’re sub-cent, high-frequency transfers, often as little as $0.000001, designed for machines, not humans. As AI agents transact autonomously, traditional rails break down. We need infrastructure built for agent-scale value exchange.

@injective 🤝

USDC and CCTP, powered by @circle, are officially coming to Injective. The world's largest regulated stablecoin. Secure crosschain transfers. All natively integrated into the fastest blockchain built for finance. Mainnet loading. ⏳

USDC and CCTP are coming soon to @injective! 🥷 This brings the world’s largest regulated stablecoin and secure crosschain infrastructure to an onchain-focused network optimized for trading, RWAs, and plug-and-play onchain finance. → Use USDC as collateral with 24/7 support → Crosschain liquidity with 1:1 capital efficiency via CCTP → Global fiat on/off ramps via Circle Mint circle.com/blog/usdc-cctp…

Building credit markets today means stitching together identity, underwriting logic, compliance workflows, and settlement rails. On Arc, developers can: → Denominate loans in stablecoins → Settle disbursements and repayments with deterministic finality → Embed compliance and privacy controls at the asset level Programmable credit starts with stablecoin-native infrastructure. Build on Arc.

AI and blockchain networks are redefining money movement. Programmable intelligence meets programmable money.

We brought 100+ developers together in Buenos Aires for our first Arc Studio. An afternoon of deep technical sessions, candid ecosystem conversations, and real builder momentum. From protocol design to funding pathways, the focus was simple: What can be shipped on Arc? The energy in the room made one thing clear. Builders are ready. Huge thank you to our panelists: @BuFi_Global @dynamic_xyz @Morpho @0xsequence This is how ecosystems compound. More to come.

AI agents are becoming builders. Circle Skills now support building with Arc and Circle’s full-stack platform, giving AI coding tools best-practice guidance for stablecoin-native applications. Use them with Cursor, Claude Code, Codex, or any agent to generate Arc integrations for: → @USDC payments → Crosschain flows → Wallet infrastructure → Smart contract logic github.com/circlefin/skil…

Calling all agents: Want to build with USDC? We built Circle Skills so you can. install: npx skills add circlefin/skills

Circle’s USYC just became the world’s largest tokenized MMF. Tokenized treasuries and repo as collateral is a major emerging use case and we are proud of how quickly this has grown. What’s especially powerful about USYC is the ability to 24/7/365 create and redeem it using USDC and a smart contract teller. Real-time money and collateral is better.
