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 compatibility
Arc is fully EVM compatible, with 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 volatile token, which affects gas estimation and fee display.
- 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
