Cryptocurrency Wallet: What It Is, How It Works, Types, & Security

In this guide, we cover everything you need to know about cryptocurrency wallets, from their core functions to key security tips for protecting your private keys.

What is a Cryptocurrency Wallet?

A cryptocurrency wallet is software that handles storage, transfer, and management based on the technology of the public ledger. It is just like a physical wallet, holding the private keys necessary to perform and authenticate transactions.

Blockchain transactions are made easier through modern cryptocurrency wallets. In earlier days of the crypto revolution, people utilized lengthy enciphering keys to transmit crypto. These days, wallets do most of the work in processing transactions more quickly and easily.

Bitcoin’s founder, Satoshi Nakamoto, created the first crypto wallet. The second recipient was Hal Finney, who received the first Bitcoin transaction of 10 BTC from Nakamoto, which started the cryptocurrency revolution.

Key Takeaways

• A cryptocurrency wallet is a safe app or device that stores your crypto keys. It allows you to manage coin transactions without any problems.

• Each wallet has two parts: a wallet address and a wallet private key. Accessing these funds requires a private key, so they are very important to keep safe.

• Different types of cryptocurrency wallets explained are created with various security features, specifically for users’ needs.

• Most wallets support multiple types of cryptocurrencies, and various ways of managing different digital assets exist in one place.

Understanding Cryptocurrency Wallets

Cryptocurrency wallets are software applications that run on computers, smartphones, and tablets. To participate in the blockchain network of your chosen cryptocurrency, you need to connect to the Internet.

Unlike physical storage, cryptocurrencies are not stored physically. However, as digital data spreads across the blockchain, they are. The app collects all bits tied to your public address and reveals the total balance in its interface. Using a crypto wallet, sending or receiving cryptocurrency is easy. To fund someone, enter the other person’s wallet address, choose how much, approve the transaction with your private key, add a fee, and confirm the transfer.

Sending is even easier: the sender enters your wallet address as though entering an email, completes the same process, and you’ll get your payment immediately from the receiver.

Cryptocurrency Wallet Types

We have two main types of cryptocurrency wallets today: custodial and noncustodial. A third party manages online wallets, known as custodial wallets or simply online wallets, which store your private keys.

These are often supplied by cryptocurrency exchanges or firms of secure data storage. Conversely, noncustodial wallets give you control over your private keys, and it is only at your discretion to secure them. Most wallets on personal devices fit in this category.

Hot and cold wallets are also further categorized. A hot wallet that remains online is much more prone to hacks because it is connected to the Internet. There are two types of wallets: a cold wallet, which is offline and prevents private keys from being online, and a cold wallet, which leaves more security in vulnerability to possible online threats.

Moreover, wallets can be divided into software, hardware, and paper. They can operate either hot or cold wallets per type.

For instance, you might use a noncustodial software hot wallet. This noncustodial hardware wallet permits users to utilize either hot or cold wallets or a custodial hardware cold wallet. Although these are the most common types, there are also variations for special access and security.

Software Wallets

Desktop and mobile apps are known as software wallets. After being installed on your computer, they allow you to access your cryptocurrency, send and accept funds, track your balance, and more. Some software wallets, especially those created by a cryptocurrency exchange, include built-in exchange features.

Mobile wallets are usually used for payment in physical stores through QR codes or near-field communication (NFC) technology. They are generally compatible with iOS and Android devices. Trezor, Electrum, and Mycelium are some of the most popular.

Most software wallets are hot, as they are always connected to the Internet and allow quick and convenient transactions.

Hardware Wallets

Private key storage offline on hardware wallets is popular as almost everyone can familiarize themselves with them. Indeed, they sometimes look like USB drives and come with very strong security features.

Plugging the wallet into your computer or phone lets you send or receive cryptocurrency. Most hardware wallets immediately sign transactions, so you do not need to type in your private key, which minimizes the chances of hacking your information.

Most of these wallets come with prices between $100 and $200, depending on features such as security, connectivity, and multi-currency support. Advanced protection comes with higher-end models, making them a great crypto storage investment. Ledger and Trezor are popular. It makes the cold wallets as they stay offline until they are needed.

Paper Wallets

In the days when cryptocurrency began, people used to write their private keys on paper, which were referred to as paper wallets. These later included QR codes so wallets could easily scan them with the help of a mobile. However, paper wallets have been lost or damaged, which is less popular today.

A paper wallet is still a secure backup if properly stored. Store it in a safe or deposit box, protect it against damage by water and fire, and periodically check it for readability. Enhanced care such as this safeguards your crypto assets from long-term security threats.

We chose companies with top security and good reputations. Wallets that score highly in this category include security features such as hardware wallet support, multiple currencies, customizable transaction fees, etc.

Crypto Wallet Security

Hackers tend to target digital assets, so securing your crypto wallet is crucial. You should also set a strong password, enable two-factor authentication on exchanges where you put funds, and keep larger sums offline for extra security.

Seed Words

A 12-word recovery phrase, commonly called a seed phrase, is a feature that most cryptocurrency wallets generate. Private keys are connected to random words such as bedroom, airport, impression, sample, protection, road, reception, shirt, etc.

This sentence helps restore your wallet and regain your funds if you lost or damaged your device. Since it gives you complete control over your crypto, users keep it safe in a secure offline location to avoid being stolen or a stealer taking over the power of your crypto.

Cryptocurrency Exchanges

Nowadays, cryptocurrency exchanges offer users the option to store their custodial keys. While that may seem convenient, it has risks. For the latest developments on exchange security breaches and regulatory changes, follow trusted sources like BTCRead.com. Storing assets on crypto exchanges makes them the first targets for hackers and susceptible to cyber-attacks.

There is another major concern regarding the financial stability of the exchanges. An exchange may shut down without recovery of your cryptocurrency. For example, in May 2022, Coinbase warned the U.S. Securities and Exchange Commission (SEC), amongst other things, that:

"Consequently, crypto assets held in custody can be considered bankruptcy estate property." Customers may be treated as general unsecured creditors if bankruptcy occurs.

Being an unsecured creditor means lower priority among bankruptcy claims. Your stored crypto could be lost permanently if the exchange doesn’t have enough money to settle the debts.

You must store your private keys offline in cold storage at the highest level of security. An extra layer of protection is placing them in a secure vault, safe, or deposit box. As your digital assets remain safer, it is harder for anyone to access your keys. It also reduces the accidental loss or access by someone you should have trusted.

The Bottom Line

Also, managing your digital assets through crypto comes down to crypto wallets. Each offers different features, giving you choices. It is necessary because you have to look for the option that would suit you, but on the other hand, you need to have strong security for your cryptocurrencies.
