What is Wallet?

A wallet is a digital application or physical device that allows individuals and businesses to store, manage, and interact with their cryptocurrency holdings. At its core, a wallet contains a pair of cryptographic keys - a private key and a public key - that are essential for authorizing and receiving transactions on a blockchain network. There are two primary types of wallets: (1) hot wallets are connected to the internet and are typically used for frequent transactions. These include mobile apps, desktop software, browser extensions, and web-based services. While they offer high convenience and fast access, they are more vulnerable to online threats such as hacking, phishing, or malware; (2) cold wallets are offline wallets that store private keys on devices not connected to the internet, such as hardware wallets (e.g., Ledger, Trezor) or paper wallets. These are considered highly secure and are ideal for long-term storage or holding large amounts of cryptocurrency, as they are immune to most forms of remote attacks.

Wallets do not physically store cryptocurrencies like a bank account stores fiat money. Instead, they provide the interface to interact with blockchain networks, allowing users to sign transactions and monitor balances associated with their addresses. Choosing the right wallet depends on a user’s needs for convenience, frequency of transactions, security level, and technical expertise.
