Everything you need to know about bridging with Arbitrum Bridge
What is Arbitrum Bridge and how does it work?
+
Arbitrum Bridge is the official bridge between Ethereum mainnet and Arbitrum One, a Layer 2 Optimistic Rollup network. It allows you to move ETH and ERC-20 tokens to Arbitrum One to benefit from significantly lower gas fees and faster transactions, all while inheriting Ethereum's robust security model.
How long does a Arbitrum Bridge transfer take?
+
Deposits through Arbitrum Bridge from Ethereum to Arbitrum One typically confirm within a few minutes. Withdrawals from Arbitrum One back to Ethereum mainnet take approximately 7 days due to the Optimistic Rollup challenge period, which is required to ensure the security of funds.
Is Arbitrum Bridge safe to use?
+
Yes. Arbitrum Bridge leverages Optimistic Rollup technology which inherits Ethereum's security guarantees. All funds locked in the bridge are protected by Ethereum validators. Always ensure you are using the official Arbitrum Bridge interface and never share your private keys or seed phrase with anyone.
What tokens are supported on Arbitrum Bridge?
+
Arbitrum Bridge supports ETH and a wide range of ERC-20 tokens including popular DeFi and stablecoin assets. The supported token list is regularly updated. You can view all available tokens directly in the bridge interface when selecting your asset to transfer.
What are the fees when using Arbitrum Bridge?
+
Transaction fees on Arbitrum Bridge and Arbitrum One are typically up to 10x lower than on Ethereum mainnet. You only pay a standard Ethereum gas fee to initiate the bridge transaction. Once your funds are on Arbitrum One, you enjoy significantly reduced fees for all on-chain activity.
