​​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

The process of generating WETH is simple – you send your ETH to a smart contract that then provides WETH in return. This means that all WETH created is backed up completely by ETH reserves. Your ETH is locked in the smart contract and can be exchanged back at any time for WETH. When your ETH is returned, the contract burns the supplied WETH.

To wrap Ether, you can interact directly with the WETH smart contract, so that it takes your ETH and credits your wallet with WETH at a 1:1 ratio (you still have to pay for transaction fees). Converting back requires another smart contract interaction, but the process is pretty much the same. 

However, it’s much easier to swap another token for WETH using a crypto exchange. Let’s see how you can swap your ETH for WETH using the Uniswap DEX or directly through your Metamask wallet.
