What is WETH and why Wrapped Ether is needed?

Today, Wrapped Ether (WETH) is a token representing Ethereum (ETH) in the form of a standardized ERC-20 token. In general, all wrapped tokens are created to enable the use of a token equivalent in an environment where it does not operate. Essentially, it is a stablecoin pegged to the price of the original token and backed by it.

One of the key advantages of using WETH on decentralized exchanges (DEX) is to simplify the trading process. Now, let’s dive deeper 👉

Why is WETH needed on DEX?

About Dex

Facilitating Trading: The advantage of using WETH lies in its ability to streamline the trading process on DEX. Most decentralized exchanges deal with ERC-20 tokens. WETH allows Ethereum (ETH) to be compatible with these exchanges. Without WETH, trading ETH on such platforms would be cumbersome due to Ethereum lacking a standardized format. Using WETH enables users to easily and securely exchange ETH for other tokens on DEX, significantly simplifying the trading process for all participants.

Importance of ERC-20 Standard: ERC-20 is a technical token standard on the Ethereum blockchain. It defines a set of rules and functions that must be implemented in a smart contract to create tokens. Thanks to this standard, ERC-20 tokens are interoperable with each other and with other services operating on the Ethereum network. Utilizing a standardized token format, such as ERC-20, ensures security and convenience for users when exchanging and trading tokens on decentralized exchanges.

Increasing Liquidity and Market Accessibility: Since the majority of tokens traded on DEX are ERC-20 tokens, using WETH enhances the available liquidity on these platforms. This makes trading more efficient and provides broader market access for all participants.

Examples of using WETH on DEX

  1. Exchanging ETH for Other Tokens: Users can use WETH to exchange their ETH for other ERC-20 tokens on DEX without needing to withdraw ETH from the Ethereum network.
  2. Participating in Liquidity Provision: Participants can provide liquidity on DEX by using WETH in pairs with other tokens, allowing them to earn trading fees.
  3. Executing Complex Financial Operations: WETH can be used in more complex operations, such as orders with deferred execution or token conversions, where a standardized token format is required for successful execution.


WETH plays a significant role in decentralized finance by providing a standardized format for representing Ether on DEX. Its usage greatly simplifies the trading process, enhances market liquidity, and ensures user security. With the growing interest in decentralized finance, WETH is expected to continue playing a key role in ecosystem development.
