​​What Is Wrapped Ether (WETH) and How to Wrap It?
Wrapped Ether (WETH) is a token pegged to Ether (ETH). WETH is used in several platforms and DApps that support ERC-20 tokens. While ETH is used to pay for network transaction fees, it doesn't have the same functionality as ERC-20 tokens. You can easily convert ETH into WETH through a process known as wrapping. You can also convert WETH back into ETH at any time. Both wrapping and unwrapping follow a 1:1 ratio, meaning there are no extra costs apart from transaction fees. You can wrap your ETH manually by interacting with the WETH smart contract, which will store your ETH and give you back the exact same amount of WETH. Ethereum's DeFi ecosystem is large, and using WETH provides more opportunities for staking and investing. There are many versions of WETH, but some are more popular than others. You can even find wrapped ETH on other blockchains to use in their ecosystems. Popular uses for WETH include NFTs trading, providing liquidity to liquidity pools, and crypto lending.

About Lesson
1. Open Uniswap and connect your wallet. Make sure Ethereum is also selected as your network.

2. Select ETH in the top field and WETH in the bottom. If you click [Select a token], you should see WETH above the list.

3. Input the amount of ETH you want to convert to WETH and click the [Swap] button. 

4. You’ll now need to confirm the transaction in your crypto wallet. Don’t forget that you’ll also need to pay gas fees, so make sure to have extra ETH at hand. Check the details of the transaction and click [Confirm].

5. Now you just need to wait for the transaction to be confirmed in the blockchain. The waiting time will depend on the current network traffic. If you are in a hurry, you can speed up the transaction (i.e., pay higher fees) to have it confirmed faster.

Wrapping ETH on MetaMask

3. Input the amount of ETH you want to swap and click [Review Swap].

4. You’ll now see a quote showing the conversion rate (which should be 1:1). Click [Swap] to finalize your transaction.
