The multi-chain future of Web3 means you'll often need to move tokens across different blockchains—whether to access specific dApps, reduce gas fees, or explore new ecosystems. However, transferring assets between networks isn’t as simple as switching networks in MetaMask or sending tokens to an address. Instead, you’ll need to bridge them.

Key Principles for Cross-Network Transfers
Before bridging, keep these fundamentals in mind:
- Tokens remain on their origin network unless bridged. Sending ETH on Ethereum Mainnet keeps it there.
- Using the same address across networks doesn’t bridge tokens. Your MetaMask address works on EVM-compatible chains, but sending tokens to it on different networks doesn’t automatically move them.
- Incorrect transfers can lead to irreversible loss. For example, sending ERC-20 POL (Polygon’s token on Ethereum) to a Polygon address without bridging results in lost funds.
How to Bridge Tokens
MetaMask simplifies bridging with MetaMask Bridges, available via MetaMask Portfolio. This tool supports transfers between popular networks like Ethereum, Polygon, and Binance Smart Chain.
Steps to Bridge:
- Open MetaMask Bridges.
- Select the origin and destination networks.
- Choose the token and amount to bridge.
- Confirm the transaction.

FAQs
Can I bridge any token?
Most major tokens (ETH, stablecoins, etc.) are bridgeable, but support depends on the networks involved. Always verify compatibility.
How long does bridging take?
Times vary by network congestion and bridge type—anywhere from minutes to hours.
Are there fees for bridging?
Yes, bridging incurs gas fees on both the origin and destination networks, plus potential bridge service fees.
