Wrapped Ethereum (WETH) is a tokenized version of Ethereum designed to enhance compatibility with decentralized applications (dApps) across various blockchain networks. Each WETH token is backed 1:1 by ETH, meaning they hold the same value and can be exchanged at parity. While native ETH operates primarily on the Ethereum network, WETH expands functionality to other chains like Binance Smart Chain, facilitating seamless trading and interaction in the decentralized finance (DeFi) ecosystem.
After completing transactions with WETH, you can convert it back to native Ethereum. However, to begin, you must first add WETH to your MetaMask wallet. This guide provides clear instructions for integrating Wrapped Ether on both Ethereum and Binance Smart Chain (BSC) networks.
Understanding Wrapped Ether (WETH)
WETH serves as an ERC-20 compliant representation of Ethereum, enabling it to function efficiently within smart contracts and decentralized exchanges that primarily support token standards. Unlike native ETH, which isn’t inherently compatible with all ERC-20 platforms, WETH broadens usability while maintaining a stable peg to ETH’s market value.
Adding WETH to MetaMask on the Ethereum Network
The Ethereum mainnet is pre-configured in MetaMask, simplifying the process of adding WETH.
Set Up and Unlock Your MetaMask Wallet
Install the MetaMask browser extension from the official source and create a new wallet or unlock an existing one using your password. Always store your seed phrase securely to recover access if needed.
Verify Network Selection
Confirm that your MetaMask wallet is set to the Ethereum network. Open the network dropdown menu and select “Ethereum Mainnet” to proceed.
Import WETH as a Custom Token
Navigate to the “Assets” tab in your wallet interface and click “Import Tokens.” Select the “Custom Token” option to manually enter contract details.
Locate the Correct Contract Address
Visit a trusted data aggregator like CoinMarketCap and search for Wrapped Ether (WETH). Under the “Contracts” section, copy the Ethereum contract address. Always verify sources to avoid fraudulent tokens.
Complete the Token Import
Paste the contract address into the respective field in MetaMask. The token symbol and decimal places should auto-populate. Click “Add Custom Token” to finalize. WETH will now appear in your wallet under Ethereum network assets.
Adding WETH to MetaMask on Binance Smart Chain
To use WETH on BSC, you must first add the Binance Smart Chain network to MetaMask.
Add BSC Network Manually
Open MetaMask, click your profile icon, and select “Add Network.” Enter the following details:
- Network Name: Binance Smart Chain
- RPC URL: https://bsc-dataseed.binance.org/
- Chain ID: 56
- Currency Symbol: BNB
- Block Explorer URL: https://bscscan.com
Save the settings to add BSC to your network list.
Import WETH on BSC
With Binance Smart Chain active, repeat the token import process:
- Click “Import Tokens” and choose “Custom Token.”
- On CoinMarketCap’s WETH page, select “More” and copy the BSC contract address.
- Paste the address into MetaMask and confirm the import.
WETH will now be accessible under the BSC network in your wallet.
Using WETH Across Chains
WETH enables cross-chain functionality for trading, lending, and yield farming. Its versatility makes it a preferred choice for users engaging with multiple DeFi protocols. Remember that gas fees and transaction times may vary between Ethereum and BSC.

Frequently Asked Questions
What is the difference between ETH and WETH?
ETH is the native cryptocurrency of the Ethereum blockchain, while WETH is a wrapped ERC-20 token representing ETH. WETH ensures compatibility with smart contracts and decentralized applications that require standardized tokens.
Can I transfer WETH between different blockchains?
No, WETH exists separately on each blockchain. You must use a cross-chain bridge or exchange to move WETH from one network to another, ensuring you use the correct contract address for each chain.
Is WETH safe to use?
Yes, WETH is fully backed by ETH held in secure smart contracts. However, always verify contract addresses from reputable sources to avoid counterfeit tokens.
Why would I use WETH instead of ETH?
WETH is essential for interacting with ERC-20 based dApps, such as decentralized exchanges (DEXs) and lending platforms, where native ETH may not be directly supported.
How do I convert WETH back to ETH?
You can unwrap WETH through supported platforms like decentralized exchanges or dedicated DeFi protocols, exchanging it 1:1 for native ETH.
Do I need to pay gas fees for wrapping or unwrapping ETH?
Yes, both wrapping and unwrapping require gas fees paid in the native currency of the network you are using (ETH for Ethereum, BNB for BSC).
Conclusion
Adding Wrapped Ether (WETH) to MetaMask on multiple chains enhances your ability to participate in diverse decentralized financial activities. By following the steps outlined for Ethereum and Binance Smart Chain, you can securely manage and utilize WETH across networks. Always prioritize security by double-checking contract addresses and using trusted resources.
