Arc RPC
Arc Overview
Arc is an open Layer 1 blockchain built by Circle for stablecoin finance. It uses USDC as its native gas token, removing volatility from transaction fees and enabling predictable, dollar-based costs. Powered by Malachite, its consensus engine provides instant finality and sub-second settlement. Arc includes a built-in FX engine for on-chain currency exchange, supports EVM compatibility, and offers opt-in privacy for compliant financial operations—all fully integrated with Circle’s ecosystem tools like CCTP and Paymaster.
Interacting with Arc
Arc exposes a standard Ethereum JSON-RPC interface, allowing developers to interact with the network using familiar Ethereum tools and libraries. You can query balances, transactions, and contract state; send transactions; and deploy or interact with smart contracts directly.
Because Arc is an EVM-compatible Layer 1 optimized for stablecoin finance, most Ethereum JSON-RPC methods are supported, though certain endpoints or behaviors may differ. For the latest API details, refer to Circle’s official Arc developer documentation.
Make Arc API Calls
The quickest way to start building on Arc is to create a Quicknode endpoint and send your first JSON-RPC request.
Quicknode provides managed Arc endpoints, offering:
- High reliability — globally distributed infrastructure designed to minimize downtime
- Archive data — full historical state for in-depth queries
- Enhanced performance — optimized latency and request handling for production-grade apps
Visit the QuickStart page to create your endpoint and send your first request.
