A crypto wallet is an application or hardware device that allows individuals to store and transfer digital assets like cryptocurrencies and Non-Fungible Tokens (NFTs). There are several providers available, with Metamask being the most popular one.
After you register and download any crypto wallet, you take control of two 42-character keys. This is a public key, known as your wallet address, and a private key. You might consider your public key to be like your shareable bank account info, so you only have to copy and paste when people ask for your address. Your private key works like a password and should always remain private, for security.
Creating a crypto wallet is essential to transact with cryptocurrencies or NFTs, either on Exclusible or any other marketplace.
