In this article, we will explore what crypto wallets are, how they function, and the various types available to suit different needs.
What is a Crypto Wallet?
A crypto wallet is a digital tool that allows users to store, send, and receive cryptocurrencies securely. Unlike traditional wallets, which hold physical cash, crypto wallets store private and public keys that grant access to digital assets on the blockchain.
