Introduction
Ethereum (ETH) is the native cryptocurrency of the Ethereum blockchain, primarily used to pay gas fees for deploying or interacting with smart contracts. However, since ETH predates the ERC-20 token standard, it isn’t natively compatible with ERC-20-based applications—creating friction in decentralized finance (DeFi).
Wrapped Ethereum (WETH) solves this by converting ETH into an ERC-20-compliant token, enabling seamless integration with DeFi protocols. This guide explores WETH’s purpose, functionality, and benefits.
What Is Wrapped Ethereum (WETH)?
WETH is a 1:1 ERC-20 representation of ETH, meaning:
- Value Parity: 1 WETH = 1 ETH at all times.
- Interoperability: Works with ERC-20 DApps (e.g., Uniswap, Aave).
- Convertibility: ETH can be wrapped/unwrapped freely.
Developed by 0x Labs in 2017, WETH bridges Ethereum’s native currency and the broader ERC-20 ecosystem.

How WETH Works
Wrapping Mechanism
- Lock ETH: Send ETH to a smart contract, which holds it in reserve.
- Mint WETH: The contract issues an equivalent amount of WETH.
- Reverse Process: To redeem ETH, WETH is burned.
Platforms Supporting WETH:
- DEXs: Uniswap, SushiSwap.
- Wallets: MetaMask.
- CEXs: Binance, OKX.
Step-by-Step: How to Wrap ETH
Via Uniswap
- Connect Wallet: Select Ethereum network.
- Swap ETH → WETH: Input ETH amount, confirm transaction.
- Receipt: WETH appears in your wallet.
Unwrapping WETH
Reverse the process by selecting WETH → ETH.
Key Benefits of WETH
- DeFi Compatibility: Use ETH in ERC-20 DApps (e.g., lending, liquidity pools).
- Cross-Chain Utility: WETH works on Layer 2 networks (Polygon, Arbitrum).
- Simplified Development: Reduces coding complexity for smart contracts.
- Cost Efficiency: Avoids duplicate contract deployments.

FAQ
1. Is WETH the same as ETH?
Yes—WETH is just ETH in ERC-20 format. Values remain pegged 1:1.
2. Why can’t I use ETH directly in DeFi?
Most DeFi protocols are built for ERC-20 tokens. ETH lacks native compliance.
3. Are there fees to wrap ETH?
Only gas fees. No additional costs for conversion.
4. Can WETH be used on other blockchains?
Yes! For example, WETH on Polygon offers faster/cheaper transactions.
5. Is WETH safe?
Audited smart contracts ensure security. Always verify the platform.
Conclusion
WETH unlocks Ethereum’s full potential by making ETH interoperable with ERC-20 ecosystems. Whether you’re a developer, trader, or DeFi user, WETH streamlines transactions and expands utility across chains.
Pro Tip: Use Layer 2 networks (like Polygon) to wrap ETH and save on gas fees!
