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.
For more information on Arbitrum please see their official documentation.
To use the Arbitrum blockchain, create a Web3 API and add the Arbitrum network add-on.
