How to Convert WETH to ETH in MetaMask [Cheapest Way]

·

Ethereum (ETH) is the native cryptocurrency of the Ethereum blockchain, widely used to pay for transaction fees—commonly known as gas fees—when interacting with decentralized applications (dApps), smart contracts, or transferring tokens. While ETH powers the network, it predates the ERC-20 token standard and does not fully comply with it. This limitation makes direct integration into many decentralized finance (DeFi) platforms challenging.

To bridge this gap, Wrapped Ether (WETH) was created. WETH is an ERC-20-compliant version of ETH, allowing seamless interaction within DeFi ecosystems such as lending protocols, decentralized exchanges (DEXs), and NFT marketplaces. Essentially, 1 WETH equals 1 ETH in value—there’s no price difference—making the conversion between them a simple "wrapping" or "unwrapping" process.

If you're holding WETH in your MetaMask wallet but need ETH for transactions or withdrawals, you’ll need to unwrap it. This guide walks you through the cheapest and most efficient way to convert WETH to ETH in MetaMask, while also explaining key concepts, differences, and best practices.

What Is the Difference Between WETH and ETH?

At their core, ETH and WETH represent the same value, but they serve different technical roles on the Ethereum network.

This distinction matters because many DeFi platforms only accept ERC-20 tokens. When you deposit ETH into a DEX like Uniswap or a lending protocol like Aave, it's often automatically wrapped into WETH behind the scenes. Conversely, when you want to withdraw funds back to your wallet as spendable ETH, you must unwrap WETH.

Understanding MetaMask: Your Gateway to Web3

MetaMask is one of the most popular cryptocurrency wallets in the world, serving as a bridge between users and the decentralized web (Web3). It functions as a browser extension and mobile app, enabling users to:

One of MetaMask’s standout features is its built-in token swap functionality, which aggregates liquidity from multiple sources to offer competitive rates. Additionally, it supports custom token imports—meaning you can manually add WETH if it doesn’t appear automatically.

Security-wise, MetaMask encrypts your keys locally, so only you have access. However, it's always recommended to store large holdings in a hardware wallet and use MetaMask primarily for daily interactions.

Step-by-Step Guide: How to Convert WETH to ETH in MetaMask

Converting WETH back to ETH (also known as “unwrapping”) is a straightforward process. Here’s how to do it safely and efficiently:

Step 1: Open MetaMask and Ensure You’re on Ethereum Mainnet

Launch your MetaMask extension or app and confirm that your network is set to Ethereum Mainnet. If you're on another network like Polygon or Binance Smart Chain, switching is essential—WETH on other chains isn’t directly convertible to Ethereum’s native ETH.

Step 2: Access the “Swap” Feature

Click on the “Swap” button located at the top of the MetaMask interface. This opens the integrated swap aggregator.

Step 3: Select WETH as the Source Token

In the “From” field, click “Select a token” and type WETH. Choose Wrapped Ether (WETH) from the list.

Step 4: Set ETH as the Target Token

In the “To” field, ensure Ether (ETH) is selected. The conversion rate should show 1:1 since WETH and ETH are pegged.

Step 5: Enter the Amount to Unwrap

Input the amount of WETH you’d like to convert. MetaMask will display estimated gas fees and the final ETH amount after fees.

Step 6: Review and Confirm

Check the details carefully:

Then click Swap.

Step 7: Approve and Confirm Transaction

You may first see an approval request for WETH spending—this is normal. After approving, confirm the actual swap transaction in your wallet.

Wait a few seconds for confirmation on-chain. Once complete, your WETH will be converted to ETH and reflected in your balance.

Frequently Asked Questions (FAQ)

Why do I need to convert WETH to ETH?

You might need ETH instead of WETH when sending funds to an external wallet that doesn’t recognize wrapped tokens, paying gas fees, or withdrawing from certain platforms. While functionally similar, some services only accept native ETH.

Is there a cost to unwrap WETH?

Yes—unwrapping WETH requires a blockchain transaction, which incurs gas fees paid in ETH. These fees vary depending on network congestion but are typically low during off-peak hours.

Can I convert WETH to ETH without paying gas?

No. Any on-chain transaction—including unwrapping WETH—requires gas. However, using Layer 2 solutions or timing your transaction during low-traffic periods can reduce costs significantly.

Does MetaMask support WETH by default?

Yes. MetaMask recognizes WETH automatically in most cases. If it doesn’t appear in your wallet, you can manually add it via the “Import Tokens” option using the official contract address: 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2.

How long does it take to convert WETH to ETH?

Transaction times depend on Ethereum network congestion. Under normal conditions, confirmations take 15 seconds to 2 minutes. During high traffic, it may take longer.

Can I reverse the conversion?

Yes—just like wrapping ETH into WETH, you can re-wrap your ETH at any time through the same swap interface or by using protocols like Uniswap.
