​​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

As mentioned before, you can unwrap Ether manually by interacting with a smart contract. However, it’s simpler and safer to swap WETH for ETH. To do this, follow our previous Uniswap or MetaMask instructions, but make sure you are changing from WETH to ETH. You can also use Binance to convert your WETH.

1. Head to the Binance Convert & OTC Portal. Select WETH in the [From] field and ETH in the [To] field, and then click [Preview Conversion].

2. You’ll now see the details of the trade. Make sure to confirm them before accepting the swap. Note that Binance does not allow you to swap ETH for WETH using this method.
