What is Paper Wallet?

A paper wallet is an offline crypto storage method (a piece of paper) that includes a user's private key, public key, and wallet address. They are used to store and transact cryptocurrencies (when connected to an exchange or blockchain node). Paper wallets were primarily used around the time Bitcoin was first created but are no longer common and have been replaced by more efficient hardware and software wallets. Paper wallets are considered "cold" wallets.
