How to Wrap Ethereum: ETH to WETH

What is WETH?

Wrapped Ethereum (WETH) is a token that is pegged to the value of ETH. It can be redeemed to ETH at any point in time.

WETH and other wrapped tokens have more utility than their original tokens.

Wrapped ETH and other wrapped tokens primarily solve the low interoperability of their originals tokens.

Why Do You Need to Wrap Your ETH?

WETH serves a few specific purposes:

  • Allows interoperability: Wrapped ETH allows users from the Ethereum blockchain to use their currency ETH on another network.
  • To bid on OpenSea: OpenSea uses WETH for bidding in the auctions.
  • To buy Axies: Axies are the NFT avatars of the play-to-earn game Axie Infinity. To play Axie Infinity, you need to have a Ronin wallet. Ronin Wallet doesn’t support ETH but WETH.

To wrap Ethereum, you need to have enough ETH for the swap and pay the gas fee.

Then, head to any DEX and connect the wallet.

Lastly, swap for WETH.

Alternatively, you can also wrap Ethereum on OpenSea.

Steps to Wrap Ethereum: ETH to WETH

  1. Install MetaMask or Coinbase Wallet
  2. Connect the Wallet to DEX
  3. Swap ETH for WETH
  4. Swapping ETH for WETH on OpenSea

1. Install MetaMask or Coinbase Wallet

You can skip this step if you already installed MetaMask or Coinbase Wallet.

2. Connect the Wallet to DEX

Once you have installed any of the Ethereum blockchain-supported wallets, you need to go to any of the decentralized exchanges (DEXs).

In this article, we will be using the most popular DEX Uniswap.

You can swap for WETH on any one of the DEX such as, KyberSwap, and more.

Let’s visit Uniswap.

Now, you will be able to see the Connect Wallet option located in the top right corner of the webpage.

Then, you need to click the Wallet icon on the top right corner of the OpenSea webpage.

Now, you will be able to view your ETH balance.

You can wrap Ethereum on most of the decentralized exchanges (DEXs) and on the OpenSea platform.

The fee to wrap Ethereum may vary from $1 to $40 approximately. This totally depends on the network congestion.

If you want to unwrap, you can do so by giving the WETH on the From field and ETH on the To field of any DEX.
