For all normal bridge traffic:
We recommend you use the Bridge feature of MetaMask Portfolio:
The Linea ecosystem has a growing and diverse number of bridges operating on it.
MetaMask Portfolio's Bridge feature leverages existing aggregators and individual bridges to show the options available to you so that you can choose the provider and rate that you prefer. Then, you can perform the bridging operation right from the dapp.
For dapp teams, liquidity providers, and technology operators bridging large amounts of liquidity, please use this page to see what your best options are.
Using ecosystem bridges
As mentioned, MetaMask Portfolio's Bridge feature surveys bridges across Linea to source its routes and rates.
For more information on those bridges and how to move between Ethereum, Linea, and other networks, please see here.
There are already a large number of ERC-20 tokens available for everyday use, as well as multi-chain transfers and functionality.
Third-Party, Permissionless Bridges
You can find third-party bridges by heading over to our ecosystem portal and filtering for bridges.
Note that these are permissionless bridges. As always, you should do your own research before interacting with dapps in order to keep your funds safe.
