How to bridge to Arbitrum
Bridging moves ETH from Ethereum onto Arbitrum so you can pay fees and trade there. The safest routes are the official Arbitrum bridge or a direct exchange withdrawal.
What is bridging?
Each chain holds its own funds. Bridging moves value across chains — here, ETH from Ethereum to Arbitrum — so you can cover fees and trade.
Option 1 — Official Arbitrum bridge
- Go to the official bridge (bridge.arbitrum.io).
- Connect your wallet on Ethereum.
- Enter the ETH amount and confirm.
- Wait for it to arrive on Arbitrum.
Bookmark the official URL to avoid phishing.
Option 2 — Direct from an exchange
Many exchanges let you withdraw ETH directly to the Arbitrum network — the simplest option. Just select "Arbitrum One" as the withdrawal network.
Bridging safety
- Use only official bridges.
- Verify the network and address.
- Test with a small amount first.
