Understanding the difference between ETH (Ethereum) and WETH (Wrapped Ethereum) is crucial for anyone interacting with the Ethereum network, especially amid the recent Decentralized Finance (DeFi) boom.

These two terms may seem similar but serve distinct roles within the ecosystem. This article will explore the intricacies of ETH and WETH, their use cases, conversion processes, and how they interplay within the Ethereum world.

What is ETH

Ethereum is a decentralized, blockchain-based platform that enables the creation of smart contracts and Decentralized Applications (dApps). ETH is the native crypto for transaction fees and computational processes on the Ethereum network.

In simple terms, ETH is a decentralized application platform with a digital currency. It is traded like other cryptos and is used within the Ethereum network to facilitate transactions.

Example: If someone wants to create a decentralized application (like a voting system), they will use Ethereum's platform. To run the application, they must pay in ETH, covering the cost of computing resources.

What is WETH

WETH stands for ‘Wrapped Ethereum.’ It's a token representing ETH wrapped into an ERC-20 compatible format. Since ETH doesn't follow the ERC-20 standard, it cannot be traded directly on some decentralized platforms. WETH was created to overcome this issue.

Wrapping ETH into WETH is like converting it into a format that can be handled more easily across various decentralized platforms. It's equivalent to ETH, meaning 1 WETH is always worth 1 ETH.

Example: Imagine ETH as a dollar bill, and you need coins for a vending machine. WETH would be the coins equivalent to the dollar bill. You convert your dollar bill into coins (WETH), use them in the machine (dApps), and can convert them back to bills (ETH), if needed.

WETH plays a critical role in DeFi by enabling the trading and interaction of ETH with ERC-20 compatible platforms. As many DeFi protocols and decentralized exchanges rely on the ERC-20 standard, WETH acts as a bridge, enhancing liquidity and compatibility.

How to wrap ETH

Wrapping ETH is like changing the currency at a foreign exchange booth when traveling to another country. You still hold the same value, but it's now in a format accepted where you're going.

It is a process that helps make ETH compatible with the ERC-20 standard. Here's how you can wrap ETH:

Step 1

Choose a Platform: Select a decentralized exchange or platform that allows the wrapping of ETH.

Step 2

Connect Your Wallet: Link your ETH wallet to the chosen platform.

Step 3

Wrap the ETH: Select the amount of ETH you wish to wrap, follow the prompts, and confirm the transaction.

Step 4

Receive WETH: Once the transaction is processed, you'll receive an equivalent amount of WETH in your wallet.

Remember, while swapping ETH for WETH, you haven't traded or sold your ETH; you've just changed its format to make it more versatile. It's reversible; you can unwrap your WETH back to ETH.

How to unwrap WETH

Unwrapping WETH and converting it back into ETH is necessary for those who want to use their wrapped assets outside of specific dApps and exchanges. Here’s how to do it:

Step 1

Connect to a Platform: Any platform or a DEX that supports the WETH standard can facilitate unwrapping. Connect your wallet to the chosen platform.

Step 2

Approve the Contract: You must approve the smart contract to access your WETH. This is a standard process of granting permission for the contract to interact with your tokens.

Step 3

Convert WETH to ETH: Use the "convert" option you see on the platform or within the digital contract. This will exchange your WETH for ETH at a 1:1 ratio.

Step 4

Withdraw ETH: If you need to move your ETH somewhere else, you can withdraw them from the platform like any other crypto and send it to any Ethereum address you want

Remember, unwrapping WETH is simply reversing the process of wrapping ETH. You're taking the ETH out of its ERC-20 compatible form.

Security Considerations When Wrapping and Unwrapping ETH

Whether you are wrapping or unwrapping ETH, security is a crucial consideration. Here's what you need to know to ensure a secure process:

Choose a Trusted Platform

Always select a reputable and trusted decentralized exchange or platform for wrapping and unwrapping. Verify the authenticity of the platform's website and smart contracts to avoid fraudulent activities. The best way to verify it is to check for third-party audits, read user reviews on credible forums, and ensure that the platform's smart contracts are verified on known blockchain explorers.

Be Aware of Gas Fees

Understand that the process of wrapping and unwrapping ETH involves gas fees. Confirm the fees before proceeding to ensure they align with current network rates.

Smart Contract Interaction

When approving smart contracts, ensure you're granting permission only to known and verified contracts. Be cautious, as malicious contracts can pose risks to your funds.

Private Key Security

Ensure that your wallet containing ETH or WETH is secure and that you keep your private keys confidential. The loss or exposure of private keys can lead to a loss of funds. Legitimate platforms will never request access to your private keys at any stage. Always be cautious of such requests, as they are likely fraudulent.

Differences between ETH and WETH

Though ETH and WETH are often used interchangeably, key differences between the two are essential for users to understand.

Compliance

ETH is the native token of the Ethereum network, while WETH is an ERC-20-compliant token. This compliance allows WETH to be used across various dApps and decentralized exchanges that require ERC-20 tokens.

Use Cases

ETH is used for transaction fees and network interactions, while WETH enables ETH to be used in platforms that require the ERC-20 standard.

Conversion

ETH must be wrapped to convert it into WETH, and WETH must be unwrapped to convert it back to ETH. This process involves interacting with specific smart contracts or platforms that support wrapping and unwrapping.

Interoperability

WETH, due to its ERC-20 compliance, offers broader interoperability across various decentralized applications and platforms.

Use cases of ETH and WETH

ETH and WETH serve complementary purposes. ETH is essential for the core functionality of the Ethereum network, while WETH extends the usability of ETH to platforms and applications that demand the ERC-20 standard.

By understanding these distinctions and use cases, users can more effectively leverage the unique capabilities of both ETH and WETH.

Here are some of the use cases of ETH and WETH

Ethereum

• Smart Contracts and DApps Execution: Fuels computational processes within the network.
• Tradeable Asset: Bought, sold, and traded like other digital currencies, enabling investment opportunities.
• Collateral in DeFi: Used in lending platforms and liquidity pools, offering yield farming and other financial incentives.

Which is Better: ETH or WETH?

Choosing between ETH and WETH depends on what you plan to do within the Ethereum ecosystem. Let's explore the key considerations for both:

ETH: Being the native crypto of the Ethereum network, ETH is essential for paying gas fees in transactions and smart contract interactions. It's widely accepted across various platforms, and if you're looking to perform standard transactions or hold Ethereum as an investment, ETH might be the preferable option.

WETH: WETH offers greater compatibility with the ERC-20 standard. If you plan on engaging in activities within the DeFi space, WETH may be the better choice for its compatibility and seamless use across different dApps.

Conclusion

The distinction between ETH and WETH plays a vital role in the Ethereum ecosystem's functionality and flexibility. While ETH is the native crypto, WETH serves as its wrapped version to bridge the compatibility gap with the ERC-20 standard.

ETH is generally used for regular transactions and investment, whereas WETH facilitates broader interaction with dApps and DeFi platforms.
