What's WETH? How do I get it?

Wrapped Ether (WETH) is used to make an offer to buy an NFT or bid on an auctioned NFT.

WETH 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 decentralized, open-source 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.

This guide explains:

  • How to add WETH as a token in your MetaMask wallet

Converting ETH to WETH

You can follow these steps to convert ETH into WETH:

3. You'll be prompted to confirm the transaction using a third-party smart contract. The transaction will involve a gas fee since you are interacting with the blockchain.

4. Once the wrap is complete, you'll see a confirmation message.

If the wrapping transaction succeeds, WETH (your offer balance) will appear under Tokens in your OpenSea wallet sidebar.

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.

Adding WETH to your wallet (MetaMask)
