Arbitrum
Arbitrum is a layer 2 scaling solution that uses Optimism Ethereum's optimistic rollups with a multi-round, fault proof system.
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 more information on Arbitrum please see their official documentation.
To use the Arbitrum blockchain, create an Ethereum project and add the Arbitrum network add-on.
If you don't have an existing Ethereum project when selecting the Arbitrum network add-on, then Infura creates an Ethereum project and enables the Arbitrum endpoints.
For Ethereum JSON-RPC API usage examples, please see our Ethereum documentation.
