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). Crypto wallets are based on blockchain technologies, which enable the recording of information that makes it impossible to change, hack or cheat the system.
When you download a crypto wallet, you take control of two 42-character keys; a public key, known as your wallet address, and a private key. You can think of your public key as your shareable bank account info, so copy and paste it in when people ask for your address. Your private key works like a password and should remain private.
