A crypto wallet is essentially any application that incorporates features for storing and managing coins. A thorough explanation of how wallets function, as well as a review of the many types of crypto wallets and their applications.
It's vital to remember that cryptocurrencies are stored on the blockchain, not in the wallet. A publicly viewable address is provided to each coin/token on the blockchain. Block explorers can be used to look at these addresses. Aside from privacy, coin records, transaction histories, and address balances are open to the public.
A complicated mathematical method generates the public address from the private key. The process of producing a private key from a public key is nearly impossible to reverse. The coins are only accessible to the owner of the private key.
