A digital wallet is typically a piece of software that is used to transact with cryptocurrency and tokens. You don't actually store cryptocurrency or NFTs in your wallet. Each wallet has a unique wallet ID (referred to as a public key). Each NFT has a unique token ID. The blockchain records ownership of an NFT by associating its unique token ID with a unique wallet ID and storing that record on the blockchain. To buy or sell an NFT, the wallet owner must enter a private key (which is like a password) to authorize the transaction via the wallet. The public and private keys are cryptographically generated. With most digital wallets, you hold the keys and are in charge of your own assets. Your assets are only as safe as your private key, so it is advisable to back it up and not share it with anyone. Never give your Secret Recovery Phrase or your private key(s) to anyone or any site, unless you want them to have full control over your assets. To make the process of setting up a wallet user-friendly, there are many software wallets, such as Metamask, which equip you with a wallet address, key vault, secure login, and backup options to manage your digital assets securely. Metamask runs as a browser extension and/or mobile app, and you can be up and running in just a couple minutes. Learn more at Metamask .
