Arc mainnet is live, and Quicknode Arc RPC access is available from day one. Developers can create an Arc RPC endpoint right now and start building on the open, EVM-compatible Layer-1 designed for financial markets, real-time money movement, and agentic economic activity.
What is Arc?
Arc launches as the Economic OS for the internet: an open, EVM-compatible Layer-1 blockchain for the world's financial markets, real-time money movement, and agentic economic activity. From day one, Arc brings together USDC, local fiat stablecoins, tokenized assets, programmable Bitcoin, and leading onchain applications in one connected ecosystem. Learn more at arc.io.
Three things stand out at launch:
Stablecoins as gas, starting with USDC, so fees are predictable and dollar-based
Deterministic sub-second finality, which matters for payments, trading, and FX
Live markets from day one: lending, borrowing, trading, onchain FX, payments, and tokenized assets
Behind it all sits a geo-diverse, known institutional validator set.
Arc Mainnet RPC access on Quicknode
Quicknode supports Arc with full RPC access from launch. Because Arc is EVM-compatible, existing Ethereum tooling, libraries, and workflows carry over. If you have built on any EVM chain, you already know how to build on Arc.
An Arc RPC endpoint on Quicknode comes with the same global infrastructure, reliability, and developer experience available across every chain Quicknode supports, so teams can partner with Circle to build on Arc without standing up their own nodes.
Arc Mainnet support on Quicknode covers more than RPC:
Capability | What you get on Arc | Docs |
|---|---|---|
JSON-RPC over HTTPS and WSS, with every EVM method supported | ||
Archive, debug, and trace | Full archive nodes, including debug_traceTransaction and debug_traceBlockByNumber | |
Real-time Arc data delivered to your datastore, filtered upstream so you receive only what you need | ||
Alerts on specific addresses, event types, or onchain conditions, with guaranteed delivery |
How to get your Arc RPC URL
Log in to the Quicknode dashboard or create a free account
Create a new endpoint and select Arc Mainnet
Copy your Arc RPC URL and point your application at it
That's it. Full setup instructions, supported methods, and network details are in the Arc documentation, and the Arc chain page has current network information.
