​​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

Other wrapped versions of ETH exist across major blockchains, which increases ETH’s interoperability. Using wrapped ETH on the BNB Smart Chain (BSC), for example, allows you to trade or use WETH within the BSC DeFi ecosystem. To do this, you’ll need to withdraw ETH from Binance or another exchange into your BSC wallet. Make sure that your exchange supports the conversion from ETH to WETH before making the withdrawal.

Alternatively, you can use a bridging service. These are third-party DApps that take crypto and store it on the origin blockchain, and then mint wrapped tokens at a 1:1 ratio on the destination blockchain.

Bridging tokens often works fine, but note that moving tokens across blockchains may involve risks. There were cases where some bridges had their smart contracts compromised. If you want to bridge wrapped Bitcoin, wrapped Ethereum, or another token, carefully research the platform you use before using their bridging services.
