Enhanced interoperability is one of the greatest benefits of wrapped tokens. Wrapped tokens are crypto assets that represent a cryptocurrency from a different blockchain network or token standard. When tokens are wrapped, their value remains pegged to the original cryptocurrency while enabling cross-chain functionality.
Understanding Wrapped Ethereum (WETH)
Wrapped tokens like Wrapped ETH (WETH) function similarly to stablecoins, where their value is pegged to Ethereum (ETH). This allows ETH to be used on non-native blockchains, expanding its utility in decentralized finance (DeFi) applications such as:
- Cross-chain lending and borrowing
- Multi-chain trading
- Bridging between Ethereum and Layer 2 solutions
Every Ethereum wrapping transaction requires a custodian—typically a smart contract, merchant, or multisig wallet—to hold the original ETH and mint WETH in return. However, using third-party custodians introduces risks like hacking or protocol compromises.
Step-by-Step Guide to Unwrap WETH on Metamask
Follow these steps to convert WETH back to ETH directly in your Metamask wallet:
1. Log in to Your Metamask Wallet
- Open the Metamask browser extension.
- Enter your password to access your wallet.
2. Navigate to the ‘Swap’ Feature
- Click Swap in the wallet dashboard.
- Ensure you have enough ETH to cover gas fees.
3. Select Tokens for Conversion
- From: Choose WETH.
- To: Select ETH.
- Enter the amount of WETH to unwrap and review the estimated gas fees.
4. Execute the Swap
- Click Review Swap, then confirm the transaction.
- Wait for the blockchain confirmation (typically under 2 minutes).

Alternative Methods to Unwrap WETH
If Metamask isn’t your preferred tool, consider these alternatives:
- Decentralized Exchanges (DEXs): Platforms like Uniswap or SushiSwap allow WETH/ETH swaps.
- Centralized Exchanges (CEXs): Binance or Coinbase support WETH deposits converted to ETH.
- Bridging Protocols: Use cross-chain bridges (e.g., Polygon Bridge) for layer-2 conversions.
FAQs
Why would I unwrap WETH?
Unwrapping restores ETH’s native utility, such as paying gas fees or interacting with Ethereum-based dApps.
Are there fees to unwrap WETH?
Yes. Ethereum network gas fees apply, which vary based on congestion.
Can I unwrap WETH on mobile?
Yes. Metamask’s mobile app supports the same swap functionality.
Is unwrapping WETH reversible?
No. Once converted to ETH, you’d need to wrap it again via a custodian.

Conclusion
Wrapped Ethereum (WETH) bridges Ethereum’s liquidity to other blockchains, but unwrapping is essential for native ETH use. Metamask provides a seamless solution, while DEXs and bridges offer alternatives. Always prioritize security by verifying custodians or platforms before transactions.
