Arc

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.

Arc has surpassed $1 billion in USDC circulating supply. A milestone for the network as the ecosystem continues to grow.

SBI’s work with Circle started with bringing USDC to Japan. Erika Peterson and SBI discuss what comes next, from yen and dollar stablecoins to assets and settlement on Arc. Building toward financial infrastructure that supports activity across borders, around the clock.

Arc 🤝 @TollyLabs Tolly is an open marketplace for AI agent services, with Arc-first settlement. Live on Arc.

RT @Custarafinance: Custara is now live on the Odoo Apps store. Connect your odoo, and your posted vendor bills flows in. Every bill is checked against your policies, approved by your team, and paid in USDC on Arc. Your books stay in Odoo. Payments stay under control.

Bridge USDC to Arc, then put it to work. Explore apps across lending, trading, liquidity, and onchain markets, including @aeroxyz, @aave, @Morpho, @Uniswap, and more. Bridge once and explore Arc:

RT @aomi_labs: Introducing Agentic Fuzzer for @arc. Ship protocols from Arc Studio and find exploits before attackers do. Let #Fable5 and #GPT6 Astra be the security auditor. Big projects pay for audits before launch. Now every builder can afford one too.

RT @bleso_a: Last Friday, I ran an Arc Studio workshop for 100+ developers building with AI agents, and one thing became clear. Many developers are building products where blockchain could be genuinely useful, but the complexity of building onchain is still holding them back. A recurring theme during the session was that many developers see smart contract complexity as a barrier to building onchain. That’s what excites me about Arc Studio. Helping developers use blockchain to innovate, without needing to become smart contract experts first. I left the session inspired by what becomes possible when that barrier comes down. Let's keep building. Try it out at studio[dot]arc[io]
