The Bridge That Connects
Ethereum to Layer 2
Arbitrum Bridge is the official gateway between Ethereum and Arbitrum One — a fast, secure, and low-cost Layer 2 network powered by Optimistic Rollup technology.
Making Ethereum Accessible for Everyone
Arbitrum Bridge was built with a single clear purpose: to make the power of Ethereum accessible to every user, regardless of the size of their wallet. High gas fees and slow confirmation times have long been a barrier to entry for everyday users on the Ethereum mainnet.
By bridging assets seamlessly to Arbitrum One, Arbitrum Bridge unlocks a world where transactions are fast, cheap, and just as secure as Ethereum itself. Our mission is to accelerate the adoption of decentralized finance by removing friction from the user experience without ever compromising on security.
Bridging in Four Simple Steps
Arbitrum Bridge uses Arbitrum's native bridge protocol to move assets between Ethereum and Arbitrum One. The process is straightforward, transparent, and non-custodial — your assets are never held by a third party.
Connect Your Wallet
Connect any EVM-compatible wallet such as MetaMask, Coinbase Wallet, or WalletConnect to get started. No registration required.
Select Your Token and Amount
Choose which asset you want to bridge — ETH, USDC, ARB, or any supported ERC-20 token — and enter the amount you wish to transfer.
Confirm the Transaction
Review the transaction details including estimated fees and time, then confirm the transaction in your wallet. Deposits to Arbitrum One are near-instant.
Receive on Arbitrum One
Your assets arrive on Arbitrum One within minutes. Withdrawals back to Ethereum follow the 7-day challenge period built into Optimistic Rollup security.
Built on Optimistic Rollup Infrastructure
Arbitrum Bridge is powered by Arbitrum's battle-tested Optimistic Rollup technology. Rather than executing transactions on Ethereum's mainnet, Arbitrum bundles hundreds of transactions into a single rollup batch and posts a compressed proof to Ethereum Layer 1, dramatically reducing cost while maintaining full Ethereum-level security.
Ethereum Security
All transactions are secured by Ethereum's mainnet consensus, inheriting its full security model without compromise.
10x Faster & Cheaper
Gas fees on Arbitrum One are approximately 10x lower than on Ethereum mainnet, with faster confirmation times.
EVM Compatible
Arbitrum is fully compatible with the Ethereum Virtual Machine, so all existing Ethereum dApps work without modification.
Non-Custodial
Your private keys and assets remain fully under your control at all times. Arbitrum Bridge never holds your funds.
Open Source
The Arbitrum protocol is open source and publicly auditable, ensuring full transparency of the bridge mechanics.
Audited Protocol
Arbitrum's smart contracts have undergone extensive third-party security audits from leading blockchain security firms.
Governed by the Community
Arbitrum Bridge is part of the broader Arbitrum ecosystem, which is governed by ARB token holders through the Arbitrum DAO. Decisions about protocol upgrades, treasury allocation, and the future direction of the network are made collectively by the community.
The Arbitrum Foundation supports the ongoing development and decentralization of the protocol. As a community-governed project, Arbitrum Bridge reflects the values of transparency, decentralization, and open participation that define the Ethereum ecosystem.
