Ether (ETH) is the native cryptocurrency of the Ethereum blockchain, serving as the primary medium for staking, transactions, and gas fee payments. Wrapped Ether (WETH) enhances ETH's functionality by enabling compliance with the ERC-20 token standard, a requirement for seamless interaction with decentralized applications (dApps) and other Ethereum-based tokens.
How WETH Works
WETH is generated through a smart contract that locks ETH and mints an equivalent amount of ERC-20-compliant WETH. Key features:
- 1:1 Peg: 1 WETH always equals 1 ETH.
- Wrap/Unwrap Flexibility: Users can convert ETH to WETH (wrapping) and vice versa (unwrapping) anytime.
- Automated Burning: Unwrapping destroys WETH tokens, reducing circulating supply.

Did you know? Approximately 3% of ETH’s circulating supply is locked in WETH contracts, underscoring its critical role in DeFi ecosystems.
Why Wrap ETH as an ERC-20 Token?
ETH predates the ERC-20 standard, limiting its interoperability. WETH bridges this gap by enabling:
- Token Swaps: Trade ETH for ERC-20 tokens (e.g., DAI, USDC) via decentralized exchanges (DEXs).
- dApp Integration: Use ETH in applications designed for ERC-20 tokens without separate interfaces.
Key Benefits
- Standardized Transactions: Simplifies smart contract development by unifying ETH and token handling.
- Liquidity Access: WETH is the backbone of liquidity pools in platforms like Uniswap and Aave.
WETH vs ETH: Key Differences
| Feature | Ether (ETH) | Wrapped Ether (WETH) |
|------------------|-----------------------------------------|-----------------------------------------|
| Standard | Native Ethereum asset | ERC-20 compliant |
| Supply | Managed by Ethereum protocol | Minted/burned via smart contract |
| Gas Fees | Paid directly in ETH | Cannot pay gas fees (must use ETH) |
FAQs
1. Is WETH safer than ETH?
Both are equally secure since WETH is backed 1:1 by ETH held in audited smart contracts.
2. Can I earn interest on WETH?
Yes! Deposit WETH into DeFi protocols like Aave or Compound to earn yield.
3. How do I unwrap WETH?
Interact with the WETH contract (via platforms like MetaMask) to convert WETH back to ETH.

4. Why use WETH instead of ETH?
WETH is essential for trading, lending, or borrowing in ERC-20-based dApps.
