The MetaMask Bridge allows you to easily and securely transfer tokens between different blockchain networks. We will walk you through everything you need to know to use the bridge.
Summary
The MetaMask Bridge feature aggregates quotes from different bridge providers to give you the best rate when moving your crypto assets between networks. It streamlines the bridging process through an intuitive interface within your MetaMask wallet.
MetaMask vets the bridges they work with for security and only displays safe options. The bridge also provides transparency into fees, timing estimates, and risks for each transfer. This allows you to bridge tokens like ETH and stablecoins between networks like Ethereum mainnet, Polygon, Optimism, and more.
Recent Upgrades
Recent upgrades allow the MetaMask Bridge to swap to different token types when bridging between networks. For example, you can now bridge ETH on Ethereum and receive MATIC on Polygon in one seamless transfer. Support for multi-hop bridging is also in development, enabling bridging through multiple networks to access various destinations.
What is a MetaMask Bridge?
A blockchain bridge serves as the digital link that allows tokens to be seamlessly transferred between separate networks. For example, you might want to bridge some ETH or stablecoins from Ethereum Mainnet over to Polygon to access DeFi opportunities unique to that network.
The bridge platform essentially performs a swap – you send your crypto assets to a contract address on the source network, and the bridge guarantees that your wallet receives the equivalent value as native tokens on the destination chain. So, your funds retain the same value as they traverse blockchains.
The process works via a mechanism called cryptographic proof. When you initiate the bridge transfer, you must sign approval with your wallet’s private key. This digital signature is mathematically verified to prove you own the funds in transit, allowing the bridge to release equivalent tokens to your address on the other network.
Where Can I Find the MetaMask Bridge?
Accessing the MetaMask blockchain bridge is simple. You can use the dedicated Bridge page within the MetaMask Portfolio app, available at portfolio.metamask.io/bridge, after connecting your wallet.
The other entry point is directly through the MetaMask browser extension. Click on the prominent Bridge button on the extension homepage to get started.
From either interface, you can easily shift crypto assets between the growing roster of layer 1 and 2 networks now bridged by MetaMask.
