How to add Arbitrum to your wallet
Arbitrum works with MetaMask and other EVM wallets — you just add the network once. Here is how to add Arbitrum One, fund it with ETH, and start using it.
The easy way
Visit any Arbitrum dApp (like our Arbitrum token creator) and click "Switch network" — MetaMask will offer to add Arbitrum automatically.
Adding Arbitrum manually
In MetaMask, open Networks → Add network and enter:
- Network name: Arbitrum One
- RPC URL: https://arb1.arbitrum.io/rpc
- Chain ID: 42161
- Currency symbol: ETH
- Explorer: https://arbiscan.io
Getting ETH on Arbitrum
You need ETH on Arbitrum for fees — bridge it from Ethereum or withdraw directly from a supporting exchange.
You are ready
Once added and funded, trade on Camelot/Uniswap or create a token. Your MetaMask address is the same across Ethereum, Base and Arbitrum.
