What Are Wrapped Tokens?
Wrapped tokens represent blockchain interoperability solutions—tokenized versions of cryptocurrencies pegged 1:1 to their native assets. They enable cross-chain functionality by allowing non-native networks to utilize these assets. Key benefits include:
- Interoperability: Bridges between incompatible blockchains (e.g., using Bitcoin on Ethereum via wBTC)
- Liquidity Enhancement: Expands DeFi opportunities across ecosystems
- Capital Efficiency: Maintain exposure to one asset while participating in yield farming on another chain
Popular examples include Wrapped Bitcoin (wBTC), Wrapped CRO (wCRO), and our focus—Wrapped Ethereum (wETH).
Understanding Wrapped Ethereum (wETH)
wETH is an ERC-20 compliant version of Ethereum, solving ETH's incompatibility with ERC-20 standards. Unlike native ETH:
| Feature | ETH | wETH |
|---|---|---|
| Token Standard | Native | ERC-20 |
| Gas Fees | Payable | Not usable |
| DeFi Use | Limited | Full integration |
👉 Discover how wETH powers advanced DeFi protocols
Creation Process
- Users deposit ETH into a smart contract
- The contract locks ETH as collateral
- Equivalent wETH is minted and sent to the user
- Burning wETH redeems the original ETH
Practical Uses of wETH
OpenSea NFT Bidding
wETH streamlines NFT auctions by enabling:
- Simultaneous bids on multiple items
- Automatic bid invalidation upon acceptance
- Pre-authorized offers without separate ETH allocations
Note: wETH works only for bids, while ETH is required for instant "Buy Now" purchases.
How to Acquire wETH on MetaMask
MetaMask's integrated swap function simplifies converting ETH to wETH:
Access Swap Interface
- Open MetaMask extension
- Click "Swap" beside the "Send" button
Configure Transaction
- Select ETH as "From" token
- Choose wETH as "To" token
- Enter desired amount (1 ETH = 1 wETH)
Complete Swap
- Review gas fees and exchange rate
- Confirm transaction
- wETH appears automatically (or import via token contract address)

Frequently Asked Questions
Is wETH safer than ETH?
Both are equally secure as wETH is fully collateralized by ETH reserves in audited smart contracts.
Can I convert wETH back to ETH?
Yes, through the same process in reverse—burning wETH releases the locked ETH.
Why doesn't MetaMask show my wETH balance?
Some tokens require manual importing using their contract address. Search for "wETH contract address Ethereum" to find the correct identifier.
Are there fees for wrapping ETH?
Small gas fees apply for smart contract interactions, but no additional wrapping/unwrapping charges exist.
Which networks support wETH?
Originally an Ethereum ERC-20 token, wETH now exists on multiple EVM-compatible chains like Polygon and Avalanche.
