Wrapped Ether (WETH) is a token that represents Ether (ETH) on the Ethereum blockchain. It is created by wrapping ETH in a smart contract, allowing it to be used in decentralized applications (dApps) and on various platforms that require ERC-20 compliant tokens.The primary reason for using WETH is compatibility. Many decentralized exchanges and services operate using the ERC-20 standard, which makes WETH more versatile. By converting ETH into WETH, users can easily trade, lend, or stake their assets within these platforms. To unwrap WETH, users can convert it back to ETH at any time. The process involves submitting WETH to the smart contract, which releases the equivalent amount of ETH. This interoperability fosters greater liquidity and usability within the Ethereum ecosystem, enhancing trading experiences and expanding the range of financial services available to users.
