The Binance Smart Chain (BNB Smart Chain) and the Ethereum Mainnet are two of the most widely used blockchains in the decentralized finance (DeFi) ecosystem. Both support smart contracts, decentralized applications (DApps), and use proof-of-stake consensus mechanisms, making them popular among developers and users.
Despite their similarities and EVM compatibility, there are often needs to transfer assets or applications between these two networks. Bridging from BSC to Ethereum might seem challenging, especially for those new to DeFi. However, with modern cross-chain bridges and exchange-based methods, transferring assets has become more accessible.
This guide provides a detailed, step-by-step walkthrough of two reliable methods to bridge your assets from BNB Smart Chain to Ethereum.
What Is a Crypto Bridge?
A crypto bridge enables the transfer of digital assets between different blockchains. Since blockchains operate in isolated environments, bridges act as connectors, allowing tokens and data to move across networks. They are essential for interoperability in the decentralized web.
Using a bridge typically involves locking assets on the source chain and minting equivalent assets on the destination chain. This process ensures the total supply remains consistent while enabling cross-chain functionality.
Method 1: Using Celer cBridge
Celer cBridge is a popular decentralized bridge supporting multiple EVM-compatible chains, including BSC and Ethereum. It offers low fees and fast transactions.
Step 1: Configure Your Wallet
Ensure your MetaMask wallet is connected to the BNB Smart Chain. If it isn’t already added, you will need to manually configure the network settings.
Step 2: Access cBridge
Navigate to the cBridge website using your browser. Click the “Connect Wallet” button and select MetaMask from the options. Approve the connection request.
Step 3: Select Networks and Token
Choose “BNB Chain” as the source and “Ethereum Mainnet” as the destination. Select the token you wish to bridge—for example, Binance-Pegged ETH—and enter the amount.
Step 4: Approve and Confirm
Approve the token spending permission when prompted. Confirm the transaction details, including gas fees, in your wallet. Once approved, the transfer will begin.
Step 5: Receive Assets
After completion, switch your wallet to the Ethereum network. Your bridged tokens should now appear in your wallet.
This method supports various tokens like USDT, USDC, and BUSD. Always double-check addresses and transaction details to avoid errors.

Method 2: Using Binance Exchange
Centralized exchanges like Binance offer an alternative way to move assets between chains through deposits and withdrawals.
Step 1: Deposit to Binance
Log in to your Binance account and navigate to your Fiat and Spot wallet. Click “Deposit,” choose the token (e.g., ETH), and select “BNB Smart Chain (BEP20)” as the network. Copy the deposit address.
Step 2: Send from Wallet
In your MetaMask (set to BSC), send the tokens to the Binance deposit address. Confirm the transaction and wait for the deposit to be credited.
Step 3: Withdraw to Ethereum
On Binance, go to “Withdraw.” Select the same token, paste your MetaMask Ethereum address, and choose “Ethereum (ERC20)” as the network. Enter the amount and complete security verification.
Step 4: Confirm Receipt
The withdrawal may take a few minutes. Once processed, your assets will be on the Ethereum Mainnet.
This method is straightforward but requires a Binance account and adherence to the platform’s withdrawal limits and fees.
Comparing Bridge and Exchange Methods
Each method has its pros and cons:
cBridge (Decentralized):
- Faster for small to medium transfers
- No need for a centralized intermediary
- Supports multiple tokens natively
Binance (Centralized):
- Familiar interface for exchange users
- May be simpler for beginners
- Subject to exchange policies and limits
Fees, speed, and supported assets can vary. Always verify current network conditions before initiating a transfer.
Frequently Asked Questions
What is the difference between BSC and Ethereum?
While both are EVM-compatible and support DeFi applications, Ethereum has a larger ecosystem and higher security decentralization. BSC offers lower transaction fees but is more centralized.
How long does bridging take?
Using a decentralized bridge like cBridge usually takes 5–15 minutes. Withdrawals via Binance can take anywhere from a few minutes to half an hour, depending on network congestion.
Are there risks involved in bridging?
Yes, smart contract risks, user error, and market volatility can affect bridging. Always use reputable platforms and verify transaction details.
Can I bridge any token?
Only tokens supported by the bridge or exchange can be transferred. Always check the list of available assets before starting.
What are transaction fees like?
Fees include gas costs on both chains and possibly a bridge service fee. Using Binance may involve deposit and withdrawal fees.
Do I need native tokens for gas?
Yes, you need BNB for transactions on BSC and ETH for Ethereum to cover gas fees during the transfer process.
Conclusion
Bridging from BSC to Ethereum is essential for users looking to leverage the strengths of both blockchains. Whether you choose a decentralized bridge like Celer cBridge or a centralized exchange like Binance, the process can be seamless when following the correct steps.
Always prioritize security—double-check addresses, use official links, and keep software updated. With the right tools and knowledge, cross-chain transfers become a powerful part of your crypto strategy.
