Bridging assets to Scroll, a rapidly growing zkEVM Layer 2 solution, is a straightforward process that opens the door to a thriving ecosystem. This guide provides a clear, step-by-step walkthrough for transferring your cryptocurrencies from networks like Arbitrum, zkSync, and many others directly to Scroll.
Why Bridge to Scroll?
Scroll has quickly emerged as a major player in the Ethereum scaling landscape. Its commitment to a seamless developer and user experience is reflected in its impressive growth and vibrant ecosystem.
- Rapid Ecosystem Growth: Scroll has seen its Total Value Locked (TVL) surge, demonstrating strong adoption and trust within the DeFi community.
- Expansive DeFi Landscape: Users gain access to a diverse range of over 50 protocols, offering everything from decentralized trading to lending and NFT marketplaces.
- Enhanced Speed and Lower Costs: Transactions on Scroll are significantly faster and cheaper than on the Ethereum mainnet, with gas fees often a fraction of the cost, optimizing your on-chain activities.
Understanding Your Bridging Options
While the official bridge is a direct route, it has limitations. It primarily facilitates transfers between Ethereum and Scroll only and may have a limited selection of supported tokens. Furthermore, withdrawals can be a multi-step process.
For a more flexible and user-friendly experience, many opt for third-party bridge aggregators. These services connect multiple blockchains, offering a wider selection of tokens and often a more streamlined process. 👉 Explore advanced bridging methods
Step-by-Step Guide to Bridging to Scroll
Follow these general steps to bridge your assets using a cross-chain aggregator. The exact interface may vary, but the core process remains consistent.
- Connect Your Wallet: Navigate to your chosen cross-chain swap platform and click the "Connect Wallet" button. Select your Web3 wallet (e.g., MetaMask, WalletConnect) from the list of options and authorize the connection.
- Select Networks and Tokens: Choose the source chain you are bridging from (e.g., Arbitrum, zkSync Era, Ethereum). Then, select Scroll as your destination chain. Specify the token and the amount you wish to transfer.
- Review Transaction Details: The interface will display a summary of your swap, including the expected exchange rate, estimated gas fees, and the final amount you will receive on Scroll. Always double-check these details.
- Approve and Confirm: Initiate the transaction. Your wallet will prompt you to first approve the token spend (usually required for first-time interactions with a new contract) and then to confirm the main bridging transaction. Confirm both.
- Wait for Completion: The bridge will handle the rest. Most cross-chain transactions are completed within minutes. You can typically track the status directly on the platform.
Securing Your Cross-Chain Transactions
Asset security is paramount when moving funds across chains. Always adhere to these best practices:
- Only use well-known, audited, and reputable bridge services.
- Scrutinize all transaction details in your wallet before signing.
- Never share your private keys or seed phrases with anyone.
- Be vigilant against phishing websites and fake social media support accounts.

Are there any risks involved in bridging?
The primary risks involve smart contract vulnerabilities on the bridge itself and user error. Mitigate these risks by using trusted, audited services and carefully verifying every transaction before confirmation.
What are the gas fee costs for bridging?
You will pay gas fees on the source chain for the initial transaction. The cost depends entirely on that network's current gas prices. Some bridges may also have a small service fee.
