Adding Wrapped Ether (WETH) to your MetaMask wallet is a crucial step for anyone engaging with decentralized applications (dApps), NFT marketplaces, or DeFi platforms on the Ethereum blockchain. While ETH is the native cryptocurrency of Ethereum, WETH—its ERC-20 compatible counterpart—enables seamless interaction across smart contracts and protocols that require standardized token formats.
In this comprehensive guide, you’ll learn what WETH is, how it differs from ETH, and the exact steps to add WETH to MetaMask across multiple networks like Ethereum and Polygon. Whether you're new to crypto or expanding your wallet functionality, this tutorial ensures a smooth, secure setup.
What Is WETH?
Wrapped Ether (WETH) is a tokenized version of Ether (ETH) designed to meet the ERC-20 standard. This means it functions like any other Ethereum-based token, allowing it to be used in decentralized finance (DeFi) protocols, NFT trading platforms, and automated market makers (AMMs).
When you "wrap" ETH into WETH, you're essentially locking your ETH in a smart contract and receiving an equivalent amount of WETH in return—1 ETH = 1 WETH. The value remains identical and pegged at all times.

This conversion was created because original ETH does not fully comply with the ERC-20 standard, which many dApps expect when processing transactions. By wrapping ETH into WETH, users gain broader interoperability across the Ethereum ecosystem.
Why Use WETH?
- Required for most NFT purchases on platforms like OpenSea
- Accepted by nearly all DeFi lending and yield farming protocols
- Enables direct token swaps on decentralized exchanges (DEXs) like Uniswap
- Facilitates automated trading strategies through smart contracts
WETH vs ETH: Key Differences
While ETH and WETH have the same market value and exist on the same blockchain, they serve different technical roles:
| Feature | ETH | WETH |
|---|---|---|
| Token Standard | Native cryptocurrency | ERC-20 compliant |
| Smart Contract Compatibility | Limited | Full support |
| Use in DeFi | Requires wrapping first | Ready-to-use |
| Transfer Mechanism | Direct balance transfer | Token contract execution |
Essentially, WETH extends the utility of ETH by conforming to widely adopted token standards. You can think of it as converting cash into a prepaid card that works seamlessly across digital platforms.
You can convert between ETH and WETH at any time using decentralized exchanges or built-in wallet features—no third-party custody needed.
About MetaMask
MetaMask is one of the most popular self-custodial cryptocurrency wallets, serving over 30 million monthly active users worldwide. Available as a browser extension (Chrome, Firefox) and mobile app (iOS, Android), MetaMask allows direct access to Ethereum and EVM-compatible blockchains.
Key features:
- Full user control over private keys
- Built-in token swap functionality
- Support for multiple networks including Ethereum, Polygon, Binance Smart Chain, and more
- Easy integration with thousands of dApps
Because MetaMask supports ERC-20 tokens by default, adding WETH is both simple and secure—no complex configurations required.
How to Add WETH to MetaMask Wallet
Follow these clear steps to import WETH into your MetaMask wallet. Whether you're starting from scratch or enhancing an existing setup, this process takes just minutes.
Step 1: Create a MetaMask Wallet (If You Don’t Have One)
- Visit the official MetaMask website and download the extension or mobile app.
- Click “Create a Wallet” and set a strong password.
- Securely back up your 12-word recovery phrase—never share it or store it digitally.
- Confirm the recovery phrase in MetaMask to finalize setup.
Your wallet is now ready for use.

Step 2: Wrap ETH into WETH
Before importing, ensure you have WETH. If you only hold ETH:
- Open MetaMask and go to the Swap feature.
- Select ETH as the input and search for WETH as the output.
- Confirm the 1:1 exchange rate and complete the transaction.
- Pay the gas fee in ETH to finalize wrapping.
Alternatively, use trusted DEXs like:
These platforms allow instant ETH-to-WETH conversion with minimal fees.
Step 3: Import WETH into MetaMask
Even after wrapping, WETH may not appear immediately in your asset list. To manually add it:
- In MetaMask, click "Import tokens" below your asset balance.
- Go to the "Search" tab and type “WETH.”
- Select Wrapped Ether (WETH) from the results.
- Click "Add", then confirm.
Your WETH balance will now display alongside other tokens.
🔐 Always verify token details before adding. Only use official contract addresses from trusted sources like Etherscan or CoinGecko.
Can You Add WETH to Other Networks?
Yes! MetaMask supports multi-chain functionality, meaning you can hold WETH on various EVM-compatible networks such as Polygon, BNB Smart Chain, and Optimism.
Add WETH to Polygon Network
- In MetaMask, click the network dropdown (top-left).
- Select "Polygon Mainnet" — if not visible, click "Add network" and choose Polygon from the list.
- Once switched, click "Import tokens" > "Custom Token".
- Paste the official WETH contract address for Polygon:
0x7ceB23fD6bC0adD59E62ac25578270cFf1b9F619 - Verify the token symbol (WETH) and decimals (18).
- Click "Add Custom Token".
Now you can use WETH on Polygon for low-cost DeFi interactions and NFT trades.
🌐 Repeat this process for other chains using their respective WETH contract addresses.
Frequently Asked Questions (FAQ)
Is WETH different from ETH?
Yes. While they hold equal value, WETH is an ERC-20 token, whereas ETH is Ethereum’s native currency. WETH is required for interacting with most dApps and smart contracts due to its standardized format.
Can you add WETH to MetaMask?
Absolutely. MetaMask natively supports WETH. After wrapping ETH or receiving WETH externally, simply import it via the "Import tokens" feature.
Can you add WETH to other networks?
Yes. You can add WETH to any EVM-compatible chain supported by MetaMask—such as Polygon or BNB Smart Chain—by manually entering the correct contract address for that network.
Do I need WETH for NFT trading?
Most NFT marketplaces (e.g., OpenSea, LooksRare) accept both ETH and WETH. However, some auctions and smart contracts require WETH specifically for smoother execution.
How do I unwrap WETH back to ETH?
In MetaMask’s Swap interface, select WETH as input and ETH as output, then confirm the reverse transaction. This burns WETH and releases an equal amount of ETH.
Is WETH safe?
Yes. WETH operates through audited smart contracts maintained by Ethereum developers. As long as you interact through legitimate platforms and verify contract addresses, it's as secure as ETH itself.
Final Thoughts
Understanding how to add WETH to MetaMask unlocks full participation in the Ethereum ecosystem—from yield farming and liquidity pools to NFT collecting and DAO governance.
