MetaMask, often referred to as the "Fox Wallet," is a decentralized cryptocurrency wallet that enables users to store, manage, and interact with multiple digital assets across various blockchain networks. As one of the most widely used tools in the Web3 ecosystem, MetaMask supports seamless integration with decentralized applications (DApps), allowing users to trade, stake, play blockchain games, and participate in token sales directly from their browser or mobile app.
One of its standout features is cross-chain transfer capability — the ability to move assets like ETH or ERC-20 tokens between different blockchains such as Ethereum (ERC-20) and Binance Smart Chain (BEP-20). For beginners wondering how to perform cross-chain transfers with MetaMask, this guide provides a clear, step-by-step walkthrough using Binance Bridge, a trusted cross-chain solution.
Understanding Cross-Chain Transfers
Before diving into the process, it's important to understand what a cross-chain transfer is. Blockchains operate independently, meaning assets on one chain (e.g., Ethereum) cannot natively move to another (e.g., Binance Smart Chain). Cross-chain bridges solve this by locking tokens on the source chain and minting equivalent tokens on the destination chain — effectively enabling interoperability.
This functionality enhances user flexibility, reduces transaction costs (by moving to lower-fee chains), and expands access to DeFi ecosystems across multiple networks.

Step-by-Step Guide: Transfer ETH from Ethereum (ERC-20) to Binance Smart Chain (BEP-20)
Step 1: Ensure Funds Are in Your MetaMask Wallet
Before initiating any cross-chain transfer, confirm that your digital assets are already in your MetaMask wallet on the correct network — in this case, the Ethereum network.
- Open your MetaMask extension and verify that the active network is Ethereum Mainnet.
- Locate your wallet address (it starts with
0x...) and copy it. If your funds are stored on an exchange (like Binance or Luno), withdraw them to this address:
- Choose ETH or ERC-20 as the withdrawal option.
- Paste your MetaMask address.
- Confirm the transaction and wait for confirmation (usually takes 1–5 minutes depending on network congestion).
- Once completed, your ETH balance should appear in MetaMask.
🔐 Security Tip: Always double-check addresses before sending. Transactions on blockchain are irreversible.
Step 2: Use Binance Bridge to Initiate the Cross-Chain Transfer
Binance Bridge is a secure and user-friendly tool for transferring assets between major blockchains.
- Visit the official Binance Bridge website.
- Click “Connect Wallet” and select MetaMask from the list.
- Confirm the connection in your MetaMask extension.
- Under “From”, select Ethereum; under “To”, select Binance Smart Chain.
- Choose the asset you want to transfer — for example, ETH.
- Enter the amount you wish to transfer.
- The system will display estimated fees and arrival amount. Review carefully.
⚠️ Note: You’ll need some ETH on Ethereum for gas fees and BNB on Binance Smart Chain to receive and use the transferred assets.
- Click Next, then confirm the transaction in your MetaMask wallet.
- Wait for the bridge to process the transfer — typically within 5–10 minutes.
- Upon completion, you’ll see a confirmation message and your MetaMask may notify you of a successful transaction.

Step 3: Switch Network and View Your Assets on Binance Smart Chain
After the transfer, your ETH will be available on the Binance Smart Chain as BEP-20 ETH, but you need to adjust your MetaMask settings to view it.
- In MetaMask, click the network dropdown at the top.
Select “Binance Smart Chain Mainnet” — if it’s not listed, you may need to add it manually via Chainlist or official configuration:
- Network Name: Binance Smart Chain Mainnet
- RPC URL:
https://bsc-dataseed.binance.org/ - Chain ID: 56
- Symbol: BNB
- Block Explorer:
https://bscscan.com
- Once switched, go to CoinMarketCap or similar site, search for Ethereum (ETH), and click “Add to MetaMask” under contract details.
Alternatively, manually add the BEP-20 ETH token contract address:
- Contract Address:
0x2170ed0880ac9a755fd29b2688956bd959f933f8(for ETH on BSC) - Token Symbol: ETH
- Decimals: 18
- Contract Address:
- Click Add Token, then confirm.
You should now see your ETH balance in MetaMask under the Binance Smart Chain network.
Frequently Asked Questions (FAQ)
Q: Is it safe to use cross-chain bridges like Binance Bridge?
A: Yes, Binance Bridge is operated by a reputable exchange and uses audited smart contracts. However, always ensure you're visiting the official website and never share your private keys.
Q: Why can’t I see my tokens after transferring?
A: This usually happens because the receiving network isn't selected in MetaMask or the token hasn’t been added manually. Double-check your network settings and add the correct token contract if needed.
Q: Do I need BNB for this process?
A: Yes. While ETH pays gas fees on Ethereum, you’ll need a small amount of BNB on Binance Smart Chain to cover future transactions once your assets arrive.
Q: How long does a cross-chain transfer take?
A: Most transfers via Binance Bridge complete within 5–15 minutes, though delays can occur during periods of high network congestion.
Q: Can I reverse a cross-chain transfer?
A: No. Like all blockchain transactions, cross-chain transfers are irreversible. Always verify recipient networks and amounts before confirming.
Q: Are there fees involved?
A: Yes. You’ll pay a nominal bridging fee plus gas fees on both chains (ETH for Ethereum, BNB for BSC). These support network security and validator operations.
Best Practices for Secure Cross-Chain Transfers
- Always verify URLs: Scammers often create fake bridge sites. Only use official links.
- Start with small amounts: Test the process with a small transfer before moving larger sums.
- Keep seed phrases offline: Never enter your recovery phrase into any website or app.
- Enable two-factor authentication (2FA) on associated accounts.
- Monitor transaction history: Regularly review your wallet activity for unauthorized actions.
MetaMask continues to play a vital role in democratizing access to decentralized finance by simplifying complex processes like cross-chain transfers. With proper knowledge and caution, users can confidently navigate multi-chain environments and take full advantage of the expanding Web3 landscape.
