Wrapped Ether (WETH) is a token that represents Ether (ETH) on Ethereum-compatible platforms. Since ETH cannot be directly used in some decentralized applications (dApps) or decentralized exchanges (DEXs) that require an ERC-20 token format, WETH provides a solution.When you “wrap” ETH, you convert it into WETH, which maintains a 1:1 value ratio with ETH. This conversion is achieved through a smart contract that holds the ETH in reserve while issuing an equivalent amount of WETH. Users benefit from WETH by being able to participate in various DeFi protocols, lending, and trading activities that require ERC-20 tokens. This enhances liquidity and usability across the ecosystem.To convert WETH back to ETH, the process involves “unwrapping,” where the WETH is returned to the smart contract in exchange for the original ETH. This seamless mechanism allows for greater flexibility and integration within the Ethereum environment.
