What is Wrapped Ethereum (WETH)?

Wrapped ETher (WETH) is essentially a version of Ether (ETH) but differs in numerous ways. WETH can be used on various platforms and decentralized applications (DApps) that support the ERC-20 token standard. WETH is pegged to ETH at a 1:1 ratio and can easily get converted. This leads to better interoperability on the Ethereum blockchain.

ETH can be wrapped manually by interacting with the WETH smart contract. WETH can also be created using decentralized exchanges (DEXs) such as Uniswap.

This guide will cover everything you need to know about Wrapped Ethereum (WETH).

What are wrapped tokens?

A cryptocurrency that's built on top of one blockchain network to be used on a different blockchain needs to be wrapped. Each token, or coin, is also built on specific standards.

Decentralized Finance (DeFi) use cases and DApps support specific standards. If the coin or token in question isn't supported by the blockchain, it needs to be wrapped.

Wrapped tokens make it a possibility to get a much higher level of utility for specific coins or tokens. Wrapped tokens solve incompatibility issues, and are supported by crypto wallets.

The procedure of wrapping a token is to swap one token for another token in an equal amount. This typically occurs through the usage of a smart contract or code on the blockchain, which can store or send funds.

Both tokens represent the same value. However, the Wrapped WETH version gets a higher level of compatibility. Wrapped tokens can be bought directly, or a merchant can convert their existing cryptocurrency and wrap it. The merchant, in this case, would send the person's crypto to a custodian.

The custodian would lock up the coin or token in a vault. Once the coin is locked, the custodian can create a wrapped token.

The wrapped token will represent the original coin, and this is a process known as minting.

What Is Wrapped Ethereum (WETH)?

Wrapped Ethereum (WETH) is essentially an ERC-20 token standard-compliant cryptocurrency that's pegged to the value of Ether (ETH). Ethereum’s native token, ETH, is used for paying gas fees on the network.

Wrapped Ethereum WETH can't be used for the payment of gas fees on the Ethereum network. WETH however, has a wider range of use cases when compared to ETH, specifically within the field of Decentralized Finance (DeFi).

Any cryptocurrency wallet that supports the ERC-20 token standard supports WETH.

Not every token built on Ethereum is alike. The network lets developers create new rules and standards for cryptocurrencies. There's the ERC-721 format, for example, that enables non-fungible tokens (NFTs) to operate on top of Ethereum. These are different when compared to ERC-20 tokens.

The majority of crypto wallets support ERC-20.

Most Decentralized Finance (DeFi) applications accept ERC-20 tokens for investment, staking, adding liquidity, borrowing, or lending, alongside other functionalities.

If we want to, for example, add Ether (ETH) to a liquidity pool and use it as collateral, it's better to have an ERC-20 version of the coin. In other terms, on Ethereum, almost all fungible tokens follow ERC-20. The standard was created to have a standardized set of rules for tokens. The aim is to simplify the new token launches and make them comparable to each other.

There are mandatory rules that all ERC-20 tokens follow, such as totalSupply, balanceOf, transfer, transferFrom, approve, and allowance.

Ether by itself doesn't comply with this token standard.

WETH is built to increase interoperability between blockchains and make Ether usable in dApps.

Some traders find themselves confused about ETH and WETH. But let's "unwrap" the distinctions between these two tokens and explore the decentralized possibilities.

ETH (Ethereum)

Ethereum, the blockchain platform, has its native token known as ETH. This digital currency serves as the lifeblood of the Ethereum network, enabling users to conduct transactions and pay gas fees. However, while ETH is a fundamental component of Ethereum, it has certain limitations regarding DeFi applications.

  • ETH is the native token used for transactions and gas fees on the Ethereum blockchain

  • Traders must exchange ETH to complete transactions on the Ethereum network

  • ETH isn't ERC-20 compliant, which can restrict its seamless integration with some DeFi applications

WETH (Wrapped ETH)

Enter Wrapped Ether, or WETH, the enchanting counterpart to ETH in the DeFi realm. WETH acts as a container, embracing the original ETH tokens and wrapping them in an ERC-20 compliant standard. This transformative process breathes new life into ETH, making it compatible with many DeFi apps.
