 Ether (ETH) is the main currency of Ethereum. It's used for several purposes like staking, as a currency, and paying for gas fees for computation. **WETH is effectively an upgraded form of ETH with some additional functionality required by many applications and [ERC-20 tokens](/glossary/#erc-20)**, which are other types of digital assets on Ethereum. To work with these tokens, ETH must follow the same rules they do, known as the ERC-20 standard.
 
 To bridge this gap, wrapped ETH (WETH) was created. **Wrapped ETH is a smart contract that lets you deposit any amount of ETH into the contract and receive the same amount in minted WETH** that conforms to the ERC-20 token standard. WETH is a representation of ETH that allows you to interact with it as an ERC-20 token, not as the native asset ETH. You will still need native ETH to pay for gas fees, so make sure you save some when depositing.
