How to use the MetaMask Portfolio Bridge​

We recommend using MetaMask Portfolio to bridge to and from Linea.

Our friends at MetaMask have already put together a guide on using the Bridge feature, available here. If you encounter any issues, check the FAQs at the bottom of the guide; if your question isn't answered there, you can easily access MetaMask Support via the chat button in MetaMask Portfolio.

Use the Linea bridge​

note

Bridging with the official Linea bridge is only recommended for technically-minded users. For most, the MetaMask Portfolio Bridge is more suitable.

You can also view alternative options at the ecosystem portal. Head to linea.build/apps and select the 'Bridge' filter.

The Linea native bridge has two methods for "claiming" the funds on the destination network. The one you need depends on the direction of your bridge and whether you're bridging ETH or ERC-20 tokens:

  • Automatic claiming means that your funds will automatically appear in your account once the bridge transfer is complete. You cannot use automatic claiming for ERC-20 bridging.
  • Manual claiming means you'll need to return to the bridge to claim the funds when the transfer is ready to complete, so only choose this option if you have some ETH on the destination network to cover the gas fees.

Automatic claiming is not available when bridging L2 -> L1.

I used the Linea bridge but my tokens aren't appearing. What do I do?​

  1. Make sure your bridged funds aren't waiting to be claimed. If you bridged using manual claiming—which you will have needed to if you were bridging from L1 to L2 for the first time—then you need to return to the bridge and click the 'Claim funds' button next to the relevant transaction.

  1. Check the status of your transaction on Lineascan:

    • Here for L1 -> L2 transactions (deposits)
    • Here for L2 -> L1 transactions (exit transactions)

    If your transaction is showing up here, it's in the queue and will be processed. Or, if it's labelled as 'Pending claim', you just need to return to the bridge and claim it.
