# Arbitrum

Arbitrum is an Ethereum scaling solution that provides high throughput and low-cost smart contract execution.

Arbitrum is EVM-compatible, and developers can connect via Arbitrum's node API. The Arbitrum node is compatible with Ethereum's JSON-RPC API implementation, which allows using tools such as Infura, Truffle, and MetaMask. For Ethereum JSON-RPC API usage examples, please see our [Ethereum documentation](broken://pages/jjagORiusiMspLbb2VSF).

For more information on Arbitrum please see their [official documentation](https://developer.offchainlabs.com/docs/developer_quickstart).

To use the Arbitrum blockchain, create a Web3 project and add the Arbitrum network add-on.
