Cryptocurrency—wallet types

A way to manage, secure, and use cryptocurrencies such as Bitcoin

(CRYPTO: BTC) and Ethereum (CRYPTO: ETH) and other digital assets

based on a blockchain (for example, an NFT) is a crypto wallet. Software

wallets and hardware wallets are the two types of blockchain wallets. The

software wallets include Web (or crypto exchange) wallets, mobile wallets,

and desktop wallets. A hardware wallet is a physical device that secures

access to your cryptos offline.
