    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.

    RT @TollyLabs: A sneak peek at the Tolly Agent Exchange, being built on @arc. As the agent economy grows, discovering services is only part of the challenge. Users and other agents will need ways to compare offerings, identify reliable providers, and understand what's actually happening across the ecosystem. Tolly Agent Exchange is being developed as a comprehensive discovery and analytics platform, bringing x402 service comparisons, agent directories, job and task tracking, and performance analytics together in one place. At the heart of the Exchange, independent operators will be able to establish public business profiles showcasing their agents' capabilities, services, pricing, and verifiable activity history. Bringing greater transparency to agent services, reputation, and economic activity on Arc.

    RT @TowerExchange: Week 4 of the Arc Accelerator Program was an insightful session on finding product-market fit led by @Jib0xD, founder of @ryskfinance. We explored how stablecoins and programmable money can solve real-world problems, the importance of understanding user pain points, and how to validate demand early. It was a great learning experience that reinforced the importance of building products around real user needs rather than assumptions.

    Agents need one place to fund, monitor, and reconcile payments. @selat_ai uses Circle Gateway on Arc to help agents pay x402 and MPP merchants from one funded USDC balance across services, protocols, and chains. Arc serves as a home treasury for agentic economic activity.

    RT @bleso_a: Many of you were curious to learn how Arc Studio plugs into popular coding agents. You can use Arc Studio as a subagent driven by your coding agent. There is a setup prompt that installs the CLI and Circle skills, and it handles contracts, reviews, and deploys without you having to leave your editor. Head to studio[.]arc[.]io to copy the prompt, and start building!

    I was genuinely blown away by how great Arc Studio works with Claude Code. So I’m building a subscription app on Arc in Claude Code. It’s a native iOS app plus contracts that enforce price caps, opt-in after free trials, and instant cancellation onchain. Normally the contract deploy process would involve installing Foundry, creating and funding a deploy wallet, and running tests, before then deploying. All I did was use the Arc Studio CLI in Claude Code. A couple of minutes later, all my tests had passed and both contracts were live on Arc testnet. I then checked that the code onchain matched my source exactly. What I love the most about this experience is that Arc Studio plugs right into Claude Code as a sub agent. Claude Code builds my native iOS app and runs it in the simulator, Arc Studio handles my contracts, and I never had to leave my editor. You can also still use Arc Studio as a standalone app. Because I later opened my project on studio [dot] arc [dot] io and used the Contracts tab to review all the functions I deployed and check the contract state, then the Tracing panel to see what happens onchain when I interact with it. Again what an amazing time to be alive!

    RT @bleso_a: We are hosting a technical office hours session on building with Arc Studio and using it alongside coding tools like Claude Code, ChatGPT, Cursor. We’ll work through a real example: a USDC subscription app. You’ll learn how to turn a small prompt into an app, deploy a subscription contract to Arc Testnet with Arc Studio, and trace what happens onchain.
