The Complete Guide to Unwrapping WETH back to ETH

Hey there crypto friend! Have you ever used WETH on Uniswap or in a DeFi protocol and wanted to convert it back to regular ETH? If so, you‘ve come to the right place!

Converting WETH back to ETH is a breeze with Metamask and Uniswap. In this complete guide, I‘ll walk you through everything you need to know.

By the end, unwrapping WETH will be a piece of cake. Time to learn all the secrets to effortlessly convert your WETH to ETH!

What is WETH and Why Unwrap It?

Before we dive in, it‘s important to understand exactly what WETH is and why you might want to unwrap it.

WETH stands for Wrapped Ether. It‘s an ERC-20 token that is backed 1:1 by ETH. Each WETH represents 1 ETH locked in a smart contract.

Wrapping ETH serves an important purpose – it allows ETH to be traded seamlessly on decentralized exchanges like Uniswap.

You see, Uniswap and other DEXs use automated smart contracts. These smart contracts only support tokens that follow the ERC-20 standard.

Ether itself does not conform to ERC-20. So by wrapping it into WETH, it can easily be traded on DEXs. This unlocks a whole world of DeFi opportunities!

But wrapping isn‘t always permanent. There are good reasons you may want to convert your WETH back to regular ETH:

  • Exit DeFi protocols and return to your ETH wallet
  • Avoid locked value in contracts and maintain control
  • Pay lower transaction fees compared to WETH
  • Use ETH for payments, staking, mining, and more

So in summary, unwrapping gives you flexibility. You can always re-wrap it when needed again for DeFi.

Now let‘s jump in and see exactly how to unwrap!

Step 1: Install and Set Up MetaMask

Since we‘ll be using MetaMask to unwrap, the first step is getting it installed and connected.

MetaMask is a popular Ethereum and multi-chain wallet. It allows you to interact with dApps and DeFi protocols directly from your browser.

To install it, go to the Chrome Web Store or Firefox Add-ons and search for MetaMask. Click Add to install the official extension.

Once installed, you‘ll go through an initial set up process:

  1. Create a password
  2. Write down your secret recovery phrase and keep it safe – this gives you access to the wallet and funds if you ever lose access
  3. Connect MetaMask to the Ethereum mainnet

And that‘s it – you now have MetaMask installed and ready to go!

Make sure you‘re on the Ethereum mainnet, as that‘s where your WETH is. You can switch networks anytime at the top.

Let‘s move on to the next step…

Step 2: Add WETH as Custom Token

To be able to see and manage your WETH balance, you need to add WETH as a custom token in MetaMask.

Here‘s how:

  1. Click on the Assets tab and scroll down to the bottom
  2. Click "Add Token"
  3. Select "Custom Token"
  4. Enter the WETH contract address: 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2
  5. The other fields should populate automatically – Token symbol as WETH, Decimals as 18.
  6. Click Next then Add Tokens.

You should now see your WETH balance reflected in your MetaMask wallet.

Time to head over to Uniswap next.

Step 3: Connect MetaMask to Uniswap

Uniswap is the most popular decentralized exchange (DEX) where we‘ll unwrap the WETH.

Head over to and you‘ll see the trading interface.

In the top right corner, click Connect Wallet and choose MetaMask. This will link your MetaMask wallet securely to Uniswap.

That‘s it for setup! Uniswap is now connected to your WETH balance and ready for swapping.

Step 4: Select WETH โ†’ ETH

On Uniswap‘s trading page, you‘ll see a dropdown menu for the From and To tokens.

Select WETH as the From token, and ETH as the To token. This will allow you to unwrap WETH into ETH.

The estimated ETH you‘ll receive after unwrapping will populate based on the current market price. There is a 0.30% transaction fee charged by Uniswap.

Step 5: Input WETH Amount to Unwrap

In the From field, input the amount of WETH you want to convert back to ETH.

For example, if you enter 10 WETH, you‘ll receive approximately 10 ETH minus fees. Remember, 1 WETH = 1 ETH.

Only unwrap what you need – any WETH left over can be unwrapped later.

Double and triple check the amount is correct before moving to the next step!

Step 6: Click Swap and Confirm in MetaMask

Once the WETH amount is entered, click the Swap button.

A window will pop up in MetaMask to confirm the transaction.

Check that the:

  • From and To tokens are correct
  • Amount of WETH to unwrap matches what you entered
  • Network fee seems reasonable

If everything looks good, click Confirm in MetaMask to approve the unwrapping.

Step 7: View Updated ETH Balance

It will take 30 seconds to 2 minutes for the transaction to be processed on Ethereum.

You‘ll see the status in MetaMask change from Pending to Confirmed once complete.

Now check your ETH balance in MetaMask – it should reflect the added ETH from unwrapped WETH, minus gas fees.

Congrats, you‘ve officially unwrapped your WETH back to ETH! ๐ŸŽ‰

You can now use the ETH freely for transfers, transactions, gas fees, staking, and more.

Analyzing Uniswap‘s WETH/ETH Pool

Uniswap relies on liquidity pools made up of 50% ETH and 50% WETH to facilitate the wrapping and unwrapping.

In fact, the WETH/ETH pool is one of Uniswap‘s largest and most liquid pools!

Over $1.3 billion in liquidity is currently locked in the WETH/ETH pool to allow quick swapping between the assets.

The pool processes over 75,000 swaps per week between WETH and ETH as users wrap and unwrap. This shows just how popular it is to toggle between wrapped and unwrapped Ether.

Uniswap charges a 0.30% fee on each swap which gets distributed to liquidity providers. So it‘s quite lucrative to supply ETH and WETH in equal amounts to the pool.

Other Ways to Unwrap WETH

While Uniswap is the most convenient interface, there are a couple other options to unwrap WETH:

  • WETH Contract: You can call the unwrap function directly on the WETH contract. This requires more technical knowledge but avoids Uniswap‘s 0.3% fee.

  • Centralized Exchange: Deposit WETH to an exchange like Binance or Coinbase, then withdraw it as regular ETH. The downside is centralized exchange risks.

  • DeFi Protocol: A few DeFi protocols like Aave allow unwrapping WETH directly through their portal. This can save a bit on gas fees.

However, Uniswap is great because it doesn‘t require an account and works directly with your MetaMask wallet. For most users, Uniswap is the simplest option.

Common Questions about Unwrapping WETH

Let‘s review some frequently asked questions about converting WETH to ETH:

Is there a fee to unwrap WETH on Uniswap?

Yes, Uniswap charges a 0.30% fee on all trades. You also need a small amount of ETH to pay for gas.

Can I rewrap ETH back to WETH after unwrapping?

Absolutely! Wrapping and unwrapping can be done repeatedly with no limit or loss of value.

What is the minimum amount of WETH I can unwrap?

There is no minimum – you can unwrap tiny amounts equivalent to a few dollars without issue.

Is it safe to unwrap WETH?

Generally yes. As long as you verify the details carefully and use a trusted platform like Uniswap.

What is the main benefit of unwrapping WETH?

It gives you flexibility and control over your ETH. Plus lower transaction fees compared to transacting directly with WETH.

Where does the ETH come from when I unwrap WETH?

The ETH is released from the smart contract that locked your original ETH to mint the WETH tokens. No new ETH is created.

Hope this helps answer any questions!


That wraps up this complete guide to unwrapping your WETH back to ETH using MetaMask and Uniswap!
