Add Arbitrum to Metamask
Getting Arbitrum on Metamask is simple and is same as adding any other EVM blockchains. All you need to do is enter the network details on Custom RPC addition feature on your MetaMask.
Open Metamask extension and drop down the “Ethereum Mainnet” at the top right corner. This opens networks where you can choose different EVM blockchain or you can add a new custom EVM (Ethereum virtual machine) network of your choice.
Click on the Custom RPC and enter the following details to add Arbitrum One network.
Network Name: Arb1
RPC: https://arb1.arbitrum.io/rpc
Chain ID: 42161
Currency Symbol: ETH
Block Explorer URL: https://arbiscan.io
Once done click save to add the Arbitrum One network to Metamask. Once saved Metamask will automatically switch over to the Arbitrum One network. Simply click on the network button at the top right to choose Ethereum network or to switch between the EVM blockchains.
That’s it! You’ve successfully added the Arbitrum network to Metamask.
Now to use Arbitrum One (L2), you need to bridge your assets from Ethereum mainnet onto Arbitrum. For this you need to use the Arbitrum bridge to bridge your ETH & tokens from L1 to L2.
