Converting Wrapped Ether (WETH) back to Ether (ETH) is a common need for users navigating the decentralized finance (DeFi) ecosystem. Whether you're preparing to pay gas fees, withdraw funds, or rebalance your portfolio, doing so efficiently and securely matters. With 1inch, one of the leading DeFi platforms, swapping WETH to ETH is not only simple but optimized for speed, cost-efficiency, and protection against transaction manipulation.
This guide walks you through how to seamlessly swap WETH to ETH using 1inch, leveraging advanced features like Fusion and the next-generation Fusion+ for better rates, zero gas fees, and enhanced security.
Why Swap WETH to ETH?
WETH is a tokenized version of ETH that conforms to the ERC-20 standard, enabling it to be used across DeFi protocols that require ERC-20 compatibility. However, native ETH is still required for paying gas fees and certain wallet interactions. Converting WETH back to ETH restores full functionality on Ethereum-based networks.
The 1inch platform simplifies this conversion with smart routing, deep liquidity aggregation, and advanced execution mechanisms—ensuring you get the best possible rate with minimal slippage.

How to Swap WETH to ETH on 1inch
Swapping WETH to ETH on 1inch is intuitive and user-friendly, whether you're new to DeFi or an experienced trader.
Step-by-Step Process:
- Access the 1inch dApp: Open app.1inch.io in your browser and connect your wallet (e.g., MetaMask).
- Set Your Tokens: In the swap interface, select WETH under “You pay” and ETH under “You receive.”
- Enter Amount: Input the amount of WETH you’d like to convert.
- Choose Mode: Opt for Fusion mode to benefit from MEV protection and gasless execution.
- Review Details: Check the estimated output, slippage tolerance, and network fee.
- Confirm Swap: Click “Permit and Swap,” then approve the transaction in your wallet.
Once confirmed, the platform routes your swap across multiple liquidity sources to ensure optimal execution.
Key Benefits of Using 1inch Fusion
1inch doesn’t just aggregate liquidity—it redefines how swaps are executed through its proprietary Fusion technology.
MEV Protection
Miner Extractable Value (MEV) refers to profits miners or validators can make by reordering or inserting transactions. This often leads to front-running or sandwich attacks, where malicious actors exploit your trade for profit.
With Fusion, your swap is protected because transactions are bundled and matched directly with professional market makers called resolvers. These bundles are submitted as a single unit, shielding individual trades from manipulation.
Gasless Swaps
One of the biggest hurdles in DeFi is needing native tokens (like ETH) to pay gas fees—even when you’re trying to get ETH. Fusion solves this by allowing resolvers to cover gas costs on your behalf. This means you can swap WETH to ETH even if your wallet has zero ETH balance.

Smart Order Execution
Fusion uses a dynamic order-filling system where resolvers compete to fulfill your swap within your specified parameters. You can set:
- Preferred exchange rate
- Time limit for execution
- Execution speed preferences
Alternatively, use the “Auto” setting for a hands-free experience.
Optimal Efficiency via Dutch Auction Model
Fusion employs a Dutch auction-style mechanism for executing large orders. The swap is broken into smaller chunks, and resolvers gradually fill them at progressively better prices. This reduces price impact and often results in an average execution rate above market value—maximizing your returns.
Introducing Fusion+: The Future of Cross-Chain Swaps
Fusion+ is a major upgrade to the original Fusion protocol, enabling secure, self-custodial, and gasless cross-chain swaps. While standard Fusion operates within a single chain, Fusion+ extends these benefits across multiple blockchains.
Key Features of Fusion+:
- Cross-Chain Compatibility: Swap tokens across Layer 1s and Layer 2s—including Ethereum, Arbitrum, Polygon, Optimism, Base, Avalanche, and more.
- No Gas Fees: Resolvers cover transaction costs on both source and destination chains.
- Full Asset Control: Your funds never leave your custody—no bridges or third-party intermediaries involved.
- MEV Protection Across Chains: Transactions remain secure from front-running regardless of network.
This makes Fusion+ ideal for users looking to move assets between ecosystems efficiently and safely—without complex bridge processes or hidden fees.
Other WETH Swap Options
While converting WETH to ETH is essential for gas payments, WETH is also widely used in trading pairs across DeFi. On 1inch, you can swap WETH for hundreds of other tokens across supported networks such as:
- Ethereum
- Arbitrum
- BNB Chain
- Avalanche
- Polygon
- zkSync
- Gnosis Chain
- Optimism
- Base
- Aurora
If a token isn't listed, you can manually add it using its contract address.
Whether you're trading stablecoins like USDC or exploring new DeFi projects, 1inch aggregates liquidity from DEXs like Uniswap, SushiSwap, Curve, andBalancer—ensuring you always get competitive rates.
