Wrapped Ether (WETH) is used to make an offer to buy an NFT or bid on an auctioned NFT.
WETH is a form of cryptocurrency that allows users to make pre-authorized bids that can be fulfilled at a later date without any further action from the bidder. WETH is minted when a user sends ETH to the WETH smart contract. The smart contract holds the ETH sent by users and mints an equivalent amount of WETH. OpenSea does not mint WETH or exchange ETH for WETH, and OpenSea does not operate or control the WETH smart contract.

Converting ETH to WETH
You can follow these steps to convert ETH into WETH:
1. Navigate to the top-right corner of OpenSea and click your Wallet balance.
2. Under the Wrap tab, enter the amount of ETH you’d like to wrap and click Add to offer balance.
3. A MetaMask window will appear, asking you to confirm the transaction. The transaction will involve a gas fee, since you are interacting with the blockchain.
4. Once the wrap is complete, you'll see the following message:
If the wrapping transaction succeeds, WETH will appear in the Offer balance section of your wallet, and in your balance dropdown.
When bidding or making an offer on an item, you'll also be able to add more WETH to your wallet by clicking Add WETH.
