WETH vs ETH: What’s the Difference and Why Does It Matter?

TL;DR

  • ETH is Ethereum’s native cryptocurrency, essential for paying gas fees and running smart contracts. 
  • WETH, or Wrapped Ethereum, is an ERC-20 token version of ETH, created for compatibility with DeFi protocols. 
  • ETH is foundational for the blockchain, while WETH enables advanced functionalities like liquidity provision and token swaps. 
  • To convert ETH to WETH, a smart contract locks ETH and issues WETH in return. 
  • WETH is crucial for interacting with DeFi platforms but cannot replace ETH for gas fees. 

Both serve distinct purposes, making them equally important in the Ethereum ecosystem.

Ethereum (ETH) is one of the most recognized cryptocurrencies globally, serving as the backbone of the decentralized finance (DeFi) ecosystem. However, if you’ve been in DeFi or blockchain technology for some time, you’ve likely encountered the term WETH or “Wrapped Ethereum.”

In this article, we’ll dive deep into weth vs eth to help you understand the difference between the two and why WETH plays a crucial role in the Ethereum ecosystem.

What Is ETH (Ethereum)?

Ethereum, or ETH, is the native cryptocurrency of the Ethereum blockchain. Often referred to as digital fuel for running decentralized applications (dApps), ETH is essential for facilitating transactions and deploying smart contracts.

Primary Use Cases:

  • Gas Fees: ETH is used to pay for transaction fees on the Ethereum network.
  • Smart Contracts: It powers the execution of decentralized applications.
  • Store of Value: ETH is also viewed as a store of value and an investment asset, much like Bitcoin.

What Is WETH (Wrapped Ethereum)?

WETH, or Wrapped Ethereum, is an ERC-20 token that represents Ethereum. Unlike ETH, WETH adheres to the ERC-20 token standard, making it compatible with DeFi protocols and dApps.

Why WETH Exists:

Ethereum was developed before the ERC-20 token standard was introduced. As a result, ETH is not ERC-20 compliant. This limitation makes it difficult for ETH to interact seamlessly with many DeFi platforms, which heavily rely on the ERC-20 standard. WETH bridges this gap by wrapping ETH in an ERC-20-compatible form.

WETH vs ETH: Key Differences

Let’s break down the differences between wrapped eth vs eth:

Technical Structure:

  • ETH: ETH is the native cryptocurrency of the Ethereum blockchain, designed to facilitate transactions and smart contract executions.
  • WETH: WETH is essentially ETH that has been “wrapped” to comply with the ERC-20 token standard. It exists as a tokenized version of ETH, allowing it to function seamlessly within the DeFi ecosystem.

Token Standard Compatibility:

  • ETH: Since ETH predates the ERC-20 standard, it does not comply with this widely adopted framework. As a result, ETH cannot natively interact with many DeFi platforms and smart contracts that operate on ERC-20 tokens.
  • WETH: WETH was created to overcome this limitation. By adhering to the ERC-20 token standard, WETH ensures compatibility with decentralized applications, decentralized exchanges, and other DeFi protocols.

Use Cases in DeFi and dApps:

  • ETH: Primarily used to pay gas fees for transactions on the Ethereum network and for direct wallet-to-wallet transfers. Its role is more foundational within the blockchain ecosystem.
  • WETH: Plays a pivotal role in DeFi and dApps. It is used for activities such as liquidity provision, token swaps on decentralized exchanges (DEXs), yield farming, and staking in liquidity pools. Essentially, WETH acts as a utility token in the DeFi space.

Smart Contract Support:

  • ETH: While ETH is central to the Ethereum blockchain, it lacks the ability to interact directly with many DeFi smart contracts due to its incompatibility with the ERC-20 token standard.
  • WETH: Offers a solution by enabling full smart contract compatibility. This compatibility is critical for DeFi operations, as it allows WETH to participate in automated trading, lending protocols, and staking mechanisms.

By addressing the limitations of ETH, WETH opens the door to a host of advanced functionalities within the decentralized finance ecosystem, making it a cornerstone of modern DeFi operations.

How Does WETH Work?

Wrapping ETH:

To convert ETH to WETH, users send their ETH to a smart contract, which locks the ETH and issues an equivalent amount of WETH.

Example Transaction:

  1. A user wants to provide liquidity to a Uniswap pool but needs WETH.
  2. They swap ETH for WETH using a WETH exchange.
  3. The smart contract locks their ETH and sends back an equivalent amount of WETH.

Why Wrapping Is Essential for DeFi:

By wrapping ETH into WETH, users gain access to a broader range of DeFi opportunities. This includes trading on decentralized exchanges, participating in yield farming, and providing liquidity.

Why Is WETH Important in DeFi?

Interoperability with ERC-20 Tokens:

WETH ensures seamless compatibility with the ERC-20 ecosystem, enabling efficient trading, lending, and borrowing on DeFi platforms.

Use Cases for WETH:

  • Liquidity Provision: WETH is a staple in many liquidity pools.
  • Yield Farming: Many DeFi platforms require WETH to participate in yield-generating activities.
  • Token Swaps: On platforms like Uniswap or Rubic, WETH facilitates token-to-token exchanges.

For example, when you use platforms like Rubic, you can swap WETH to ETH or vice versa instantly, providing unmatched convenience.

How to Swap WETH to ETH (and Vice Versa)

Instant Swaps Using Rubic:

Rubic offers a seamless platform to swap WETH to ETH or any other ERC-20 token. The process is user-friendly and quick, making it an excellent choice for both beginners and experienced traders.

Is WETH Better Than ETH?

Whether WETH or ETH is better depends on the specific use case.

When to Use ETH:

  • Paying for gas fees.
  • Direct wallet-to-wallet transactions.

When to Use WETH:

  • Interacting with DeFi protocols.
  • Participating in liquidity pools or staking.
  • Conducting token swaps on DEXs.

Future of WETH: Will It Ever Be Replaced?

As the Ethereum ecosystem evolves, a common question arises: Will WETH always be necessary?

The Need for WETH in the Current DeFi Ecosystem:

As long as Ethereum transactions rely on the ERC-20 standard, WETH will remain an essential part of the ecosystem. WETH ensures smooth operations within DeFi, bridging the gap between ETH’s native capabilities and the standardized token requirements of decentralized platforms.

Ethereum’s Roadmap and ERC-20 Integration:

Future upgrades to Ethereum, such as better interoperability and scaling, may eliminate the need for wrapping ETH. The Ethereum network’s move towards greater compatibility could phase out WETH, but for now, WETH continues to be indispensable in supporting DeFi’s growth and accessibility.

Conclusion: Which One Should You Use?

Both ETH and WETH serve unique purposes within the Ethereum ecosystem. While ETH is crucial for network transactions, WETH is indispensable for DeFi applications. For most users, understanding when to use WETH versus ETH can maximize their opportunities in the blockchain space.
