What is an Arc RPC node?

An Arc RPC node is a server that exposes Arc's JSON-RPC API, letting applications query blockchain data, submit transactions, and interact with smart contracts deployed on the network. Developers use Arc RPC nodes to build stablecoin payment, FX, and tokenization apps without running their own node infrastructure.

How is Arc different from other EVM blockchains?

Arc is EVM-compatible but purpose-built for stablecoin finance. The most significant difference is its gas model: Arc uses USDC as the native gas token. Arc also offers deterministic sub-second finality and opt-in privacy features designed for institutional and regulated workloads.

What is GetBlock's Arc RPC service?

GetBlock provides reliable RPC node access to Arc, giving developers high-availability endpoints without the cost or complexity of running their own node infrastructure. This includes access to the full Arc JSON-RPC API.

Which wallets and libraries work with Arc RPC?

Because Arc is EVM-compatible, it works with standard Ethereum-compatible wallets, including MetaMask, libraries, and development frameworks. Connect by adding the Arc RPC URL and the Chain ID to your wallet or Web3 client.

What data can Arc RPC nodes access?

Arc RPC nodes return account balances, transaction histories, block data, smart contract states, event logs, and gas estimates through the standard Ethereum JSON-RPC interface.

How do I connect to Arc RPC?

Connect to Arc RPC using GetBlock's HTTPS or WebSocket endpoint along with a standard Ethereum-compatible client library. Add the Arc Chain ID to your wallet or Web3 client configuration, and you're ready to send transactions, query state, or subscribe to real-time chain events.

What are common Arc RPC methods?

Because Arc is EVM-compatible, it exposes the standard Ethereum JSON-RPC interface with methods like eth_blockNumber, eth_getBalance, eth_sendRawTransaction, eth_call, and debug/trace methods. Most Ethereum JSON-RPC methods work on Arc out of the box, though some endpoints or behaviors may differ from Ethereum mainnet.

Does Arc RPC support real-time data streaming?

Yes. Arc supports WebSocket subscriptions, providing real-time streams of new blocks, pending transactions, contract event logs, and account state changes. This is essential for payment processors, treasury systems, FX engines, and trading applications that need live data without polling overhead.

What is Arc Chain ID?

Arc Mainnet uses Chain ID 5042 and Arc Testnet uses Chain ID 5042002. The Chain ID is essential when adding Arc to a wallet or configuring a Web3 client, so make sure it matches the network you are connecting to.

Does Arc have a block explorer?

Yes. Arc provides an official block scanner, showing detailed views of transactions, blocks, addresses, smart contract verification, and stablecoin transfers on the network.

Arc is an EVM-compatible Layer 1 blockchain developed by Circle, the "Economic Operating System" for onchain finance. Arc uses USDC as its native gas token, giving applications predictable, dollar-denominated transaction costs. Powered by the Malachite consensus engine, a Tendermint BFT protocol, Arc delivers sub-second deterministic finality. Built to meet the throughput demands of global financial infrastructure, Arc aims to deliver settlement headroom far beyond what legacy systems like Fedwire process daily.

Beyond its stablecoin-native gas model, Arc ships with Circle infrastructure built in: StableFX for institutional onchain foreign exchange, CCTP for cross-chain USDC transfers, and Gateway for unified multichain balances. With opt-in privacy controls and audit-ready compliance features, Arc serves fintechs, asset issuers, treasury teams, AI agent developers, and enterprises building regulated financial infrastructure.
