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.

With the Arc Studio CLI, Claude Code, Codex or Cursor can hand off onchain work. Inspect the sandbox, review the results and pull code back into your project.
