Depending on the device that is used to install MetaMask, you will have either the Browser extension (desktop) or app (mobile). Follow the initial instructions to either create or import an existing (Ethereum) account.

  2. Go to the GMI Marketplace and click on Connect to Metamask on the top right corner of the page.

  1. Navigate to the NFT you want to sell and click on Sell in the top-right corner. If you don't see the Sell button, make sure you're connected to the correct wallet.
