What Is Wrapped Ether (WETH)?
Wrapped Ether (WETH) is an ERC-20 token pegged 1:1 to Ethereum’s native cryptocurrency, Ether (ETH). While ETH is used primarily for gas fees, WETH expands utility by enabling compatibility with ERC-20 standards, making it indispensable for DeFi protocols, liquidity pools, and smart contracts.

Why Wrap ETH?
ETH isn’t natively ERC-20 compliant, limiting its use in DeFi applications that require standardized tokens. Wrapping ETH into WETH:
- Ensures seamless integration with ERC-20 DApps.
 - Enables participation in liquidity pools and collateralized loans.
 - Simplifies developer workflows for smart contracts.
 
How to Wrap ETH into WETH
Step-by-Step Guide:
- Connect your wallet (e.g., MetaMask) to a DEX like Uniswap.
 - Select ETH as the input token and WETH as the output.
 - Enter the ETH amount and click "Wrap".
 - Confirm the transaction in your wallet (gas fees apply).
 
Note: Wrapping is reversible—WETH can always be unwrapped for ETH.
How to Unwrap WETH Back to ETH
Reverse the process:
- On Uniswap, select WETH as the input and ETH as the output.
 - Click "Unwrap" and approve the transaction.
 - The burned WETH is converted back to ETH in your wallet.
 
Cross-Chain Wrapped ETH
WETH exists on multiple blockchains (e.g., BSC, Polygon) via:
- Bridging services: Convert ETH to WETH on other chains (1:1 ratio).
 - Exchange withdrawals: Some platforms support direct ETH-to-WETH swaps.
 
Caution: Research bridge security to avoid smart contract risks.
Price Parity Between WETH and ETH
WETH maintains a 1:1 peg with ETH due to:
- Arbitrage opportunities that balance supply/demand.
 - Convertibility ensuring WETH’s value mirrors ETH’s market price.
