A cryptocurrency wallet is a tool that allows users to interact with the blockchain system in three different forms: software, hardware, and paper. These wallets can also be categorized as hot or cold depending on their internal workings. Let's examine all about crypto wallets, including their differences and how crypto wallets work.

What is a Crypto Wallet and How Does It Work?

So, what is a crypto wallet, and how does it work? Let's take a detailed look at its functionality.

Contrary to what many people believe, crypto wallets are not designed to hold digital assets. Instead, they provide a means of interacting with the blockchain. In other words, these wallets can generate the information required to transmit and receive cryptocurrency through transactions. This data is composed of one or more sets of public and private key pairings.

How to use a crypto wallet? In order to utilize a crypto wallet, you must first generate an address by fusing your public and private keys. This produces an alphanumeric ID that is saved in the wallet. This particular combination of signs designates a particular place in the blockchain where you can get coins. To accept payments, you can share your address with other individuals, but you should never reveal your private key.

Regardless of the type of wallet you choose, the private key is necessary to access your cryptocurrency. With the correct private key or seed phrase and a different device, you can still access your funds even if your computer or smartphone has been compromised.

Note that the coins do not leave the system, but instead, they flow between addresses.

Hot and Cold Crypto Wallet: What is the Difference?

As we've noted above, depending on how they operate, crypto wallets can be classified as either "Hot" or "Cold."

Any kind of Internet-connected wallet qualifies as a hot wallet. For example, you might deposit money into your Binance hot wallet when you register for an account on the Binance exchange and add money to your account. For traders and other regular users, these wallets are practical because they are simple to set up and offer instant access to money.

Cold wallets, on the other hand, aren't connected to the Internet. They are less susceptible to hacking since they keep keys offline on physical media instead. As a result, cold wallets are a significantly safer way to store coins. This process, also called cold storage, is best suited for hodlers or long-term investors.

Types of Crypto Wallets

Now, let's take a closer look at each type of crypto wallet to get a full understanding of the difference between them.

Web Wallets

Using web wallets eliminates the need to download or install additional software to access the blockchain through the browser interface. This rule is valid for all browser-based wallets, including those found on exchanges. Most of the time, you can make a new wallet and secure it with a unique password, but certain businesses will manage your private keys instead. For less experienced users, this method could seem handier, but remember that web crypto wallets are actually less safe.

Desktop Wallets

Unlike other web-based options, a desktop wallet is a software you install and use on your computer, giving you total control over your keys and money. A file named "wallet.dat" is downloaded to your computer when you establish a new wallet. It's recommended that you encrypt this file with a special password because it contains details on the key needed to access your addresses.

Your desktop wallet must be encrypted for the application to read the wallet.dat file, so you must enter your password each time the program is launched. You won't have access to your money if you misplace your file or forget your password.

Due to this, "wallet.dat" should always be backed up and kept in a secure location. Also, if your computer is down, you can export the associated private key or seed phrase and access your money using another device.

In general, desktop wallets are thought to be safer than the majority of web-based alternatives. But, it's crucial to check your computer for malware and viruses before setting up and utilizing such a wallet.

Mobile Wallets

Mobile wallets are built primarily as smartphone applications, yet they perform the same functions as their PC counterparts. This makes it very convenient to transfer and receive cryptocurrency via QR codes.

When utilizing cryptocurrencies in the real world, mobile wallets are a great alternative for routine transactions and payments. Trust Wallet is a fantastic illustration of a mobile cryptocurrency wallet that works well for this use.

Hardware Wallets

A hardware wallet works as follows: it produces both public and private keys by utilizing a stochastic number generation (SNG). The device isn't linked to the Internet, and those keys are stored right there. In this way, this type of wallet is cold and is considered one of the most secure options available.

Paper Wallets

A paper wallet, in turn, consists of a piece of paper with a written address and a QR code and acts as the private key for crypto wallets.

You can produce a new address and key offline by downloading code from a paper wallet using several services. As a result, if someone wishes to access your paper crypto wallet, it'll be complicated to hack the system.

However, it still isn't recommended to use paper wallets to store cryptocurrency due to several drawbacks. It's important to be aware of all the risks if you decide to use it nonetheless. Paper wallets' biggest flaw is that you can only send the entire sum at once; they are not suitable for sending portions of your money.


As you can see, crypto wallets are a key middleware for those who use cryptocurrency. They are one of the main pieces of infrastructure that enable both sending and receiving funds within the blockchain. Each type of crypto wallet has its own benefits and drawbacks. That's why it's vital to have a full understanding of how to use a crypto wallet and learn its principles of work to utilize them.
