Arc Mainnet is live. Arc launches as the Economic OS for the internet: an open platform for global markets, real-time value movement, tokenized assets, and agentic economic activity. Arc is more than a blockchain. It launches as a full-stack financial platform with assets, applications, interoperability, developer infrastructure, and Circle platform services live from day one. Arc delivers USDC as native gas, deterministic sub-second finality, EVM compatibility, and institutional validators. It integrates with Arc Studio, App Kits, Arc Portal, Circle Agent Stack, CCTP, Gateway, CPN, and StableFX. A complete economic platform at genesis. Arc launches with infrastructure for: → Agentic economic workflows → Lending and borrowing → Trading and liquidity → Onchain FX → Payments and settlement → Tokenized assets → Exchanges, wallets, custody, compliance, data, and developer tooling 190+ institutional and ecosystem builders are building across Arc.

Just over 2 weeks since launch, $500M+ deposited into Morpho on @arc

Borrow Kit is now available on Arc Mainnet. Developers can integrate crypto-backed USDC borrowing directly into their apps without stitching together DeFi infrastructure themselves. → Morpho borrow markets for BTC/USDC → BTC-to-cirBTC orchestration and atomic transaction execution → Flexible wallet adapters and gas sponsorship capabilities → Lending protocol data, collateral health, and liquidation alerts Less infrastructure work for devs. A more direct way for users to access USDC without selling sats. arc.io/blog/let-your-users-b…

As new financial markets take shape on @Arc, tokenized assets are already there. $JTRSY, $JAAA and $HYB bring Treasuries, AAA CLOs and high-yield credit onchain, giving users and builders access to a broader range of institutional assets from day one.

Arc 🤝 @centrifuge Centrifuge is live on Arc. Real-world assets from Janus Henderson and New York Life Investment Management are being tokenized on Arc, including JAAA, JTRSY, and HYB. These assets may expand the collateral and yield surface for builders, bringing institutional-grade RWAs into a stablecoin-native environment for lending, treasury, and structured financial applications.

SINGULARRY AI AGENTS ARE LIVE ON @ARC⚡️ SINGULARRY started on BNB Chain. It doesn't stop there. Our Agents are already fully operational on Arc. As we expand the rollout, we’re adding Arc as a native deployment option, enabling users to launch and fund their SINGULARRY Agents directly on the network with USDC. And this integration means considerably more to us than simply adding another chain. Arc is being built around many of the same ideas that have shaped SINGULARRY from the beginning: Programmable money. Autonomous execution. Machine payments. DeFi. Real World Assets. Agents as economic actors. SINGULARRY brings the intelligence and autonomous execution layer. Arc provides an environment purpose-built for economic activity. @USDC provides programmable money and settlement. And our newly expanded technology stack provides another critical component: the ability for Agents to transact. Through our x402 infrastructure, we're working toward a future where a SINGULARRY Agent can autonomously discover and pay for data, APIs, compute and services, while operating within permissions defined by its user. But payments are only one part of it. Imagine an Agent that can: → Hold and allocate capital → Search for opportunities → Execute strategies → Route liquidity → Interact with RWAs → Pay for APIs and intelligence → Consume services from other Agents → Operate across multiple financial ecosystems All autonomously. All within user-defined risk parameters. That's the direction we're building toward. And Arc is becoming an important part of it. SINGULARRY × ARC Building for the Agentic Economy.⚡️

Borrow USDC and keep your bitcoin. Borrow Kit helps developers add crypto-backed borrowing to their apps without building the underlying lending integration. At launch, users can use cirBTC as collateral to borrow USDC through @Morpho markets on Arc. No smart contract code to write. No direct protocol integration to maintain. arc.io/blog/let-your-users-b…

Tokenized stocks can be bought and traded instantly with a digital wallet. Jeremy Allaire on what that means for emerging markets with the launch of Arc.

Agents can now hire humans to capture the physical world. Live on @arc. Pay a bounty in USDC, a person goes there and films, the 3D model comes back to the agent. Ground truth for physical AI, settled in under a second, on the chain built for agent-run businesses. The first physical-world service an agent can pay for on Arc. The grid is inevitable.

AIFlow x Arc 🤝 AIFlow gives developers and agents one API for OpenAI and Anthropic models. One key connects existing tools to frontier inference through a shared pool of AI credits. Behind that endpoint, we connect to inference providers across regions and route traffic through a globally distributed network. Our provider relationships and negotiated pricing help us offer the same models at lower cost, without asking developers to rebuild their workflows. We started by serving businesses and processing more than 1B tokens a day across our B2B operations. Now we’re opening AIFlow to everyone. We chose to build on @Arc because of its focus on the agentic marketplace. As we expand on-chain, we want to work directly with teams building agents on Arc and give them a simpler, more affordable way to access the inference their products depend on.

Onramp Kit, Earn Kit, and Borrow Kit are now on Arc Mainnet. Help users get funded with USDC and put those balances to work without stitching together multiple vendors, protocols, and integrations. Embedded funding. Embedded lending opportunities. Embedded borrowing experiences. Built for Arc. arc.io/blog/build-embedded-u…

Technical Office Hours is Thursday, October 1 at 11 AM ET. Join @TxnSheng for a practical walkthrough of Onramp, Earn, and Borrow Kits on Arc Mainnet. Fiat purchases of USDC and EURC. Earn opportunities. Borrowing against crypto assets. Bring your implementation questions. Sign up: community.arc.io/home/events…

Gold meets the dollar settlement layer. Matrixdock Gold $XAUM is now live on @Arc as its first tokenized gold asset, with eligible redemption flows accessing USDC proceeds same-day. XAUm/USDC liquidity is also available on @Uniswap, connecting verifiable physical gold with Arc’s USDC-native liquidity and settlement infrastructure. #Gold has historically sat apart from dollar liquidity. On Arc, $XAUM brings the two onto the same on-chain financial infrastructure. Full announcement: matrixdock.com/blog/announce…

Uniswap is home to cirBTC, processing 90% of its trading volume on @arc Users can swap and LP on the Uniswap Web App, with no Circle account required

The agentic economy needs trust and verifiability. Arc gives AI agents trusted infrastructure to transact, coordinate, and prove what happened.

Earn Kit is now available on Arc Mainnet. Developers can integrate third-party USDC and EURC lending opportunities without stitching together DeFi infrastructure themselves. → Access to curated lending opportunities across Morpho → Vaults that lend into markets backed by ETH and BTC collateral → Crosschain deposits powered by CCTP → Built-in gas sponsorship capabilities → One integration layer for embedded lending experiences Less infrastructure work. More useful financial products on Arc. arc.io/blog/embed-usdc-yield…

Arc is an AI-first economic operating system where agents can transact, contract, and coordinate. On @tbpn, @jerallaire discusses Arc’s launch and why it’s such a huge milestone.

The Economic OS for the Internet deserves liquidity infrastructure built for institutions, AI, and the future of onchain finance. Aero is coming to @Arc ✈️

$150M+ USDC borrowed against cirBTC on @arc.
