Ethereum and Smart Contracts
The foremost concepts in a guide on wrapped Ethereum explained in detail would emphasize Ethereum and smart contracts. Ethereum is a distributed computing platform with the EVM helping developers create dApps for various use cases. Most the developer use Ethereum for the power of smart contract development. Smart contracts are self-executing programs that have the terms and rules encoded on the blockchain.
Smart contracts offer a new approach to ensuring immutable, automatic and traceable transactions on blockchain networks. When specific conditions for a transaction are fulfilled, the smart contract is triggered, and it completes the transaction according to pre-defined parameters.
Now, smart contracts have to evolve as new use cases of blockchain garner the attention of tech communities. Therefore, the new Ethereum standards define new scripting standards for supporting the emerging use cases for dApps. You can find the answer for ‘what is wrapped Ethereum’ in the fact that Ether does not support every dApp or smart contract on Ethereum. Smart contracts serve as the core element of dApps, which operate DeFi solutions on Ethereum blockchain. ETH is the primary requirement for the operations of dApps and smart contract deployment on the blockchain. As new smart contracts follow new standards such as ERC-20, it is difficult to use ETH for them.

What is Wrapped Ethereum?
The question presents a vital solution to the problem of interoperability between ETH and ERC-20 smart contracts. As the name implies, wrapped ETH is a wrapped version of Ether, the native token of Ethereum blockchain. The basic explanation of WETH suggested that it is nothing else but Ethereum, which has been ‘wrapped’ in compliance with ERC-20 token standards. Wrapped tokens and coins like WETH have the same value as the underlying asset i.e., ETH.
As a matter of fact, Bitcoin also has a wrapped variant known as Wrapped Bitcoin, pegged at a 1:1 ratio with Bitcoin. You can assume that wrapped tokens are practically similar to stablecoins, as stablecoins also have the same value as underlying assets. Just like redeeming stablecoins for fiat currencies, you can also ‘unwrap’ tokens at any time.

Working on Wrapped Ethereum
The fundamentals of wrapped tokens provide a clear impression of the stability of wrapped Ethereum price estimates. Interestingly, the process of wrapping and unwrapping tokens is simple, thereby ensuring faster transactions. Wrapped tokens have been tailored to resolve the problems of interoperability evident in most blockchains. For example, users could not utilize ETH on the Bitcoin blockchain. Wrapping helps in the tokenization of cryptocurrencies alongside wrapping them with the token standards of a specific blockchain. As a result, a specific cryptocurrency could serve use cases on another blockchain network.
One of the foremost aspects of Wrapped Ethereum would point to the fact that it is not useful for paying gas fees in Ethereum blockchain transactions. However, it can leverage ERC-20 compatibility for offering investment and staking opportunities on different DeFi apps. WETH could also serve as useful for purchasing and selling NFTs through auctions on the OpenSea marketplace.
The working of WETH involves sending Ether to a smart contract, which would generate WETH. At the same time, users have to lock ETH, thereby ensuring that the wrapped Ethereum has the backing of an Ethereum reserve. When you unwrap or exchange the WETH back into Ether, you have to burn or remove the converted WETH from circulation. This helps in ensuring that the wrapped token price remains at the same peg as the value of the underlying asset at all times. Crypto users can also access WETH by swapping other tokens on crypto exchanges such as Uniswap or Sushiswap.
