What is a Crypto Wallet? – Hot Wallet, Cold Wallet, Custodial, Non-custodial

What is a crypto wallet, and how do they work? This is a question that many people ask themselves. Upon entering the world of blockchain and bitcoin, there is a range of different terms.


What Is A Crypto Wallet?

Like a regular wallet, a crypto wallet is a software program that will store things inside. This program stores both public and private keys and interacts with various blockchain. This interaction allows users to receive and send digital currency.

If you use cryptocurrency or bitcoin, you will need a digital wallet.


How Do Crypto Wallets Work?

Although millions of people use crypto wallets, most people don’t understand them. Unlike their real-world counterparts, crypto wallets don’t store currency.

Instead, crypto wallets are software programs that store the private and public keys. A user can send currency or conduct other operations as required.

When you receive bitcoins, the person sending them is signing off ownership. The coin(s) will then register to your wallet.

To unlock or spend those coins, your wallet address and public address must match. If both the public and private matches, you’ll see your balance increase. Details matter when it comes to bitcoin.

The transaction gets recorded on the blockchain.


Are There Different Crypto Wallets?

There are several different crypto wallets. They’re divided into several categories.

Mobile wallets

A mobile wallet will run on a mobile app. The ability to use it anywhere is attractive, although they don’t have much space.


A hardware wallet, like the name suggests, is tangible—usually, a USB device. While hardware wallets do make transactions online, they are safer for storing information offline. Hardware wallets are compatible with a range of interfaces and currencies, and they are pin protected.


Accessible and convenient, these wallets are controlled by third-parties, which makes them more vulnerable. Online wallets store private keys.


You will download and install this wallet onto your computer. Only a single computer can access the wallet. It offers the highest security, but if your computer breaks or gets a virus, you may lose your wallet.


A paper wallet can be two things. The first is a printed copy of your public and private keys. The second is a piece of software that generates a pair of keys.

The keys are printed, which makes transferring bitcoin easy and straightforward. You will need to transfer funds between your paper wallet and your software wallet to spend it; this process is known as sweeping.

Hot/cold wallet

A hot wallet is a crypto wallet that is connected to the internet. A cold wallet is one that is not connected to the internet. 


A custodial wallet is where a third-party is looking after and storing your private keys. A non-custodial wallet, on the other hand, is kept and controlled by an individual.  


Are Crypto Wallets Safe?

These crypto wallets have various degrees of safety. The security level you can expect will differ based on the wallet and service provider. The top mistake with a wallet is sending money to a scammer or the wrong person. Once the currency leaves your wallet, getting it back is impossible, unless the person wants to return it.

To protect your currency, only store low amounts in your online wallet for everyday use. Paper or USB is the ideal way to give yourself protection against computer failure and loss. Keeping your software updated means you will have the highest security software.

Many users also add an extra layer of protection with complex passwords and ensuring all transfers require a password.
