Wallet Definition: A crypto wallet is where you store private keys to secure your crypto assets. The private keys are also known as passwords that provide access to your cryptocurrencies so that you can send and receive them safely.
The most common cryptocurrencies that use a wallet for this purpose are Ethereum and Bitcoin. Wallets are available in various forms, including hardware wallets, which resemble a USB stick, and online wallets. Hardware wallets are considered safer, as they store crypto assets offline.
