The Ethereum (ETH) wallet is needed first prior to purchasing Non-fungible tokens (NFT). Most NFT run on the Ethereum blockchain and allow users to deploy smart contracts which store important data about the token.
MetaMask is an extension for accessing Ethereum enabled distributed applications, or "Dapps" in your browser. Follow the instructions below on how to install MataMask:
Step 2: After MetaMask has been added as an extension, users will need to add some ETH to it. Users can purchase ETH directly on Metamask by going to “Buy,” and then selecting “Continue to Wyre.”
Make sure to add enough to cover the cost of your desired NFT and accompanying Ethereum gas fee (a fee you must pay to have your transaction authorized on the Ethereum network).
Step 3: Now that you've got your Ethereum wallet setup, you have to choose which NFT marketplace you'd like to purchase from. You can buy NFTs from OpenSea. Rarible and hundreds of other NFT marketplaces.
