Question 1

What is WETH?

Accepted Answer

WETH, or Wrapped Ethereum, is an ERC-20 token that represents Ether (ETH) on the Ethereum blockchain. Essentially, it's a tokenized version of ETH that facilitates its use in Ethereum-based decentralized applications (DApps) and smart contracts.

Question 2

How Does WETH Function and What Are Its Use Cases?

Accepted Answer

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.

Question 3

Who Created WETH?

Accepted Answer

WETH is a community-driven initiative and a fundamental part of the Ethereum DApp ecosystem. Will Warren, the co-founder of 0x, a protocol for decentralized exchange of Ethereum tokens, is one of the key figures who championed the creation of WETH. In a Medium post, he urged the Ethereum community to establish a canonical ERC20-compliant wrapped ether token (WETH) with the aim of standardizing operations across dApps and ensuring safer smart contracts. This call to action marked a significant point in the journey towards the establishment of WETH.
