MetaMask Bridges Launches Support For L2 Networks Arbitrum and Optimism | MetaMask News (2024)

After three successful months, MetaMask is proud to conclude the bridging beta period and introduce MetaMask Bridges in production, with enhanced Layer 2 support.

This brings the bridge aggregator to six supported networks:

  1. Ethereum
  2. Arbitrum
  3. Optimism
  4. Binance Smart Chain
  5. Polygon
  6. Avalanche

MetaMask Bridges supports bridging of up to $50,000 (previously $10K) per transfer of ETH/WETH, common stablecoins (eg: DAI), and native gas tokens (eg: MATIC).

Available on MetaMask Portfolio, MetaMask Bridges is one of many helpful features that make participating in web3 easily accessible. When creating a MetaMask wallet, you can connect to MetaMask Portfolio immediately after to Buy, Swap, Bridge, and Stake your crypto.

Similar to how flight aggregators help you find the cheapest and/or fastest flight, MetaMask Bridges helps you find the cheapest and/or fastest route so you know you’re getting a good deal. All in one window, and all in our Portfolio Dapp.

Now that MetaMask Bridges is production stable, and has evolved support for L2 networks and increased transfer limits, a 0.875% MetaMask fee will also be enabled, bringing it to parity with other useful features like MetaMask Swaps.

Bridging with Confidence


Instead of searching everywhere for the right bridge, you can find your desired route in Portfolio Dapp with a few clicks. MetaMask Bridges is an aggregator that integrates directly with Socket and LI.FI to support a carefully curated set of bridge providers: Connext, Hop, Celer cBridge, and Polygon Bridge.

Simply choose the recommended route or compare all the options that are collected by price and time estimates.


Bridging your assets is, after all, a core web3 activity that gets you participating and understanding the crypto ecosystem. Now, you can do so knowing that the team behind MetaMask Bridges is constantly monitoring, studying, and adapting to the dynamic bridging ecosystem to produce a secure and safe experience for you.

MetaMask Bridges aims to facilitate a smooth transition when you hop from one chain to another. The experience is frictionless, intuitive, and convenient. You don’t have to leave the dapp to get from Ethereum to Optimism and Arbitrum, you can hop over and view all your assets in the same place.

Happy bridging. 🌉
