​​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 key to maintaining WETH’s peg with ETH is its 1:1 convertibility. If WETH were cheaper, people would buy it and convert it to the more expensive ETH to make a profit. This opportunity would increase WETH’s demand and, therefore, price. If WETH were more expensive, people would purchase ETH and convert it to WETH to sell, increasing WETH’s supply and lowering its price. These principles of supply and demand ensure that the peg remains relatively stable.
