Arc

The Economic OS for the internet. Now live on mainnet.

[Arc @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.

Hold and borrow USDC. Spend in local currencies.

@RipioApp and @Morpho joined Matt Stafford to show how Arc supports payments, FX, and credit, from Brazil-to-Argentina transfers to borrowing local currency against USDC.

See how it works in the full session.

Mid-flight engine replacement complete✅

Shoutout to our chad engineers led by @dk_extended & @spooky_x10 for landing the plane with GitHub on fire, and to the @arc team for the runway.

Zero trading downtime on a volatile day.

[Extended @extendedapp]

Extended now settles on @arc.

The migration of $120 million in TVL is complete, with open positions and orders carried across. Trading continued throughout the process.

What this means for our users:
• Faster deposits and withdrawals, leveraging Arc’s sub-second finality.
• Native USDC transfers through Circle’s CCTP.
• cirBTC is now the BTC collateral asset.

Deposits and withdrawals are open again.

Hold USDC. Spend pesos.

Fixed-rate borrowing can make real-world expenses more predictable without forcing users into active currency trading.
