Ether (ETH) and Binance Coin (BNB) rank among the top cryptocurrencies by market capitalization. ETH serves as the native currency of the Ethereum blockchain, while BNB powers the BNB Smart Chain and BNB Beacon Chain. Although Metamask defaults to the Ethereum network, it supports EVM-compatible chains like the Binance Smart Chain (BSC), enabling BNB transactions.
However, direct ETH-to-BNB conversion isn’t possible within Metamask due to their separate blockchains. This guide covers two methods: using a cross-chain crypto bridge (decentralized) or Binance (centralized exchange).
Method 1: Bridging ETH to BNB Without Binance
Prerequisites
- BSC network added to Metamask.
- Binance-Pegged ETH (BEP-20) token imported.
Steps
Add BSC to Metamask:
- Visit ChainList.org, connect your wallet, and select Binance Smart Chain Mainnet.
- Click [Add To Metamask] or follow this manual guide.
Import BEP-20 ETH:
- On Metamask (BSC network), click Import Tokens.
- Paste contract address:
0x2170Ed0880ac9A755fd29B2688956BD959F933F8.
Use Celer cBridge:
- Navigate to Celer Bridge.
Connect Metamask and select:
- From: Ethereum Mainnet.
- To: BNB Chain.
- Token: ETH.
Transfer ETH:
- Enter amount, review fees, and click [Transfer].
- Confirm transaction via Metamask (5–20 min processing time).
Swap to BNB via PancakeSwap:
- Connect Metamask to PancakeSwap.
- Select ETH (BEP-20) as input, BNB as output.
- Approve swap and wait ~3–5 minutes.

Method 2: Converting ETH to BNB Using Binance
Steps
Deposit ETH to Binance:
- Copy your Binance ETH (ERC-20) deposit address.
- Send ETH from Metamask (Ethereum network) to Binance.
Convert ETH to BNB:
- On Binance, go to Convert.
- Select ETH → BNB and confirm swap.
Withdraw BNB to Metamask:
- Switch Metamask to BSC network.
- Withdraw BNB (BEP-20) from Binance to your Metamask address.
FAQs
Q1: Can I swap ETH to BNB directly on Metamask?
No. You need a bridge (like Celer) or CEX (like Binance) due to different blockchains.
Q2: Is Metamask BNB BEP2 or BEP20?
BEP20 only. Metamask doesn’t support BEP2 (BNB Beacon Chain).
Q3: Which method has lower fees?
Celer Bridge + PancakeSwap typically costs less than Binance for small amounts, but Binance offers faster processing.
Key Takeaways
- Cross-chain bridges (e.g., Celer) enable decentralized ETH-to-BNB conversions.
- Binance simplifies the process but involves higher withdrawal fees.
- Always verify contract addresses and network settings to avoid losses.
