MetaMask has rolled out a powerful update to its built-in cross-chain aggregation feature, Bridge, significantly enhancing user experience by enabling seamless, multi-asset transfers across blockchains in a single transaction. This upgrade marks a pivotal step forward in simplifying decentralized finance (DeFi) navigation for both new and experienced users.
The new functionality allows users to not only move assets between chains but also swap native tokens during the transfer—eliminating the need for multiple transactions. This means greater efficiency, lower costs, and improved accessibility across the growing multichain ecosystem.

Expanded Asset Support Across Major Blockchains
Previously limited to native network tokens and select stablecoins, MetaMask Bridge now supports nearly all major token types across its integrated networks. This expansion is made possible through strategic integrations with leading cross-chain infrastructure providers like Socket and LI.FI, which power the underlying routing logic.
Users can now bridge any ERC-20 or equivalent token directly—without relying on third-party exchanges or manual swaps. For example, you can now seamlessly convert ARB tokens on Arbitrum One into OP tokens on Optimism Mainnet within one transaction flow.
This full-token support dramatically increases flexibility, especially for users managing diverse portfolios across Ethereum Layer 2s and EVM-compatible sidechains.
Key Supported Blockchains
MetaMask Bridge currently supports nine major blockchain networks:
- Ethereum
- Arbitrum
- Optimism
- Binance Smart Chain
- Polygon
- Avalanche
- zkSync Era
- Linea
- Base
Each chain connection is optimized for speed, cost-efficiency, and security, with real-time routing suggestions based on user preferences—whether prioritizing the fastest route or the lowest fees.
All integrated bridges meet strict criteria, including:
- Minimal trust assumptions
- Atomic transaction guarantees
- External validator oversight
These safeguards ensure that user funds remain protected throughout the cross-chain process.
How to Use MetaMask Bridge: A Step-by-Step Guide
Using MetaMask Bridge is simple and intuitive. Here’s how to get started:
- Connect your MetaMask wallet to portfolio.metamask.io
- Click on the Bridge tab
- Select your source and destination networks
- Choose the token you want to send and enter the amount
- Pick the desired output token on the target chain (e.g., converting ETH to MATIC)
- Optionally review alternative bridge routes for better rates or speed
- Confirm and submit the transaction
Behind the scenes, MetaMask aggregates quotes from multiple bridge providers, ensuring optimal execution. The interface clearly displays estimated completion time, gas fees, and slippage settings—giving users full transparency before confirming.
A short tutorial video is available directly within the platform to help first-time users navigate the process smoothly.

Why This Update Matters for DeFi Users
The ability to combine swapping and bridging in one step reduces friction in cross-chain operations—a common pain point in DeFi. Before this update, users often had to:
- Swap tokens on a DEX
- Use a separate bridge protocol
- Re-swap upon arrival
Each step incurred additional gas fees and exposure to price volatility. Now, MetaMask consolidates this entire workflow into a single, secure transaction.
For traders, yield seekers, and NFT collectors alike, this means faster access to opportunities across ecosystems—from participating in an Arbitrum-based launchpad to staking OP tokens on Optimism—all without leaving the MetaMask interface.
Moreover, the integration with Socket and LI.FI ensures that even lesser-known tokens can be bridged reliably, expanding access beyond mainstream assets.
Security and Trust Considerations
While convenience is key, security remains paramount. MetaMask does not operate its own bridge but acts as an aggregator, sourcing liquidity and routes from vetted protocols. Each connected bridge undergoes rigorous evaluation based on:
- Open-source code audits
- Historical uptime and incident response
- Decentralization level of validators
This “trust-minimized” model aligns with core Web3 principles, giving users control while reducing reliance on centralized intermediaries.
Still, users should always:
- Double-check recipient networks and token selections
- Review estimated arrival amounts carefully
- Avoid using Bridge through suspicious links or phishing sites
As always, private keys and seed phrases must remain confidential.
Frequently Asked Questions (FAQ)
Q: Is MetaMask Bridge a standalone product?
A: No. It's a non-custodial aggregation layer that connects to existing cross-chain protocols like Stargate, Hop, and Synapse via partners such as Socket and LI.FI.
Q: Are there any transaction limits?
A: There are no fixed limits imposed by MetaMask itself, but individual bridge providers may enforce minimums or maximums based on liquidity and risk controls.
Q: Can I bridge NFTs using this feature?
A: Not currently. The Bridge function supports fungible tokens only. NFT bridging requires separate tools or marketplace integrations.
Q: Does Bridge support non-EVM chains like Solana or Cosmos?
A: As of now, only EVM-compatible chains are supported. Integration with non-EVM networks may come in future updates.
Q: How are routing decisions made?
A: MetaMask evaluates available paths using real-time data on fees, latency, success rates, and security models—then recommends the best option unless manually overridden.
Q: Is there a fee to use MetaMask Bridge?
A: MetaMask doesn’t charge a service fee. However, users pay standard network gas fees and potential swap/balance spreads from underlying protocols.
The Bigger Picture: Toward a Unified Web3 Experience
With over 300,000 users having already used MetaMask Bridge and more than $300 million in transaction volume, this tool is becoming a cornerstone of cross-chain interoperability. As the number of Layer 2s and app-specific chains grows, unified interfaces like this will be essential for mainstream adoption.
By supporting full-token transfers and integrating trusted aggregation layers, MetaMask continues to position itself not just as a wallet—but as a comprehensive gateway to the multichain future.
