Arc is a developer platform with a fully EVM-compatible network layer — meaning it supports the same bytecode, RPC methods, and tooling as Ethereum. Ethereum developer tools, wallets, and infrastructure work without modification.

​
Connect to Arc

Network details

RPC endpoints, chain ID, WebSocket URLs, and explorer links for Arc testnet.

Deploy on Arc

Deploy, test, and interact with a Solidity smart contract on Arc.

​
EVM differences

Arc has a few key differences from Ethereum:
  • USDC as gas: Transaction fees are paid in USDC (a stablecoin pegged to the US dollar) instead of a native token, which affects gas estimation and fee display. See Gas and fees for details.
  • Deterministic finality: Transactions finalize in under one second with no risk of reorganization, so a single confirmation is sufficient.
  • Standard tooling: Hardhat, Foundry, Viem, and other Ethereum development tools work without modification.

​
Run a node

Operate your own Arc node for independent transaction verification, direct RPC access, or data indexing. Anyone can run a node without permission.

Running a node

What a node does, how it fits into Arc’s architecture, and why you might run one.

Node requirements

Hardware, software, network endpoints, and ports needed to run a node.

Run an Arc node

Step-by-step setup for both the execution and consensus layers.

Deploy as a service

Configure systemd services that auto-restart and survive reboots.

Monitor a node

Verify sync status, view logs, and scrape Prometheus metrics.
