Wrapped Ether

The "wrapping" process involves depositing Ether into a specific smart contract. This contract retains an equivalent amount of WETH, which is then enabled for use within the Ethereum blockchain. This mechanism allows users to trade, lend, borrow, or engage with ETH in various DApps requiring ERC-20 tokens without having to directly transfer ETH, thereby improving efficiency and flexibility.

One of the major advantages of WETH is that it enables ETH trading on decentralized exchanges (DEXs) that exclusively support ERC-20 tokens. Without WETH, trading ETH on these exchanges wouldn't be possible, as they are designed to interact only with ERC-20 tokens.

Another significant benefit of WETH is its compatibility with smart contracts. Since ETH isn't inherently an ERC-20 token, its direct use in smart contracts demanding ERC-20 tokens isn't straightforward. However, when Ether is wrapped into WETH, it effectively converts into an ERC-20 token, rendering it compatible with these smart contracts.
