What Is the Definition of a Cryptocurrency Wallet?

A cryptocurrency wallet is an application that serves as a cryptocurrency wallet. It is termed a wallet because it is used similarly to a wallet in which cash and cards are stored. Instead of these actual goods, it stores the passkeys you use to sign Bitcoin transactions and provides the interface via which you may access your cryptocurrency.

Thanks to contemporary Bitcoin wallets, everyone can now view the blockchain. Sending cryptocurrency was a manual activity that required long keys when it was initially launched. The application now does the majority of the work for you. The first wallet was established by Satoshi Nakamoto, the creator of Bitcoin. The second wallet belonged to Hal Finney, who interacted with Nakamoto and is said to have been the first to use the Bitcoin client software wallet. As a test, Nakamoto sent him 10 bitcoins, and the cryptocurrency mania began.1-2

A cryptocurrency wallet is a hardware or software that stores your Bitcoin keys and allows you to access them.

- Wallets store a public key (the wallet address) as well as your private keys, which are required to sign Bitcoin transactions. Anyone with access to the private key has authority over the coins associated with that address. Wallets are available in a variety of styles, each with its own set of functions and security levels.

- Many cryptocurrency wallets are available for storing keys for various coins.

Understanding Bitcoin Wallets

Cryptocurrency wallets are software programs that run on desktops or mobile devices like phones and tablets. They link to the blockchain network for the cryptocurrency you're utilizing via an internet connection.

Cryptocurrencies are not "stored" somewhere; instead, they are bits of data in a database. These bit data bites are spread throughout the database; the wallet locates all of the bits linked with your public address and totals the amount in the app's interface for you.

These applications make it incredibly simple to send and receive cryptocurrency. Various methods exist for sending and receiving cryptocurrency from your wallet. Typically, you enter the recipient's wallet address, select an amount to transfer, sign the transaction with your private key, pay the transaction fee, and send it.

QUICK FACT

Many wallets have QR codes and near-field scanning technologies, allowing you to scan a code, enter your key, select the transaction cost, and click send.

Types of Cryptocurrency Wallets

Wallets are classified into two types: custodial and noncustodial. A third party stores your keys and hosts custodial wallets for you. This corporation may offer enterprise-level data protection technologies used by businesses to preserve and secure data. Some Bitcoin exchanges provide consumers with custodial wallets. Noncustodial wallets are those in which you are responsible for the security of your keys. 

This is the case for the vast majority of cryptocurrency wallets on mobile devices. There are two kinds of wallets: hot and cold. A hot wallet has an internet connection or is connected to another device, whereas a cold wallet does not. Finally, there are three types of wallets: software, hardware, and paper. Each of these is classified as a hot or cold wallet.

So you can have a custodial hardware cold or hot wallet, a noncustodial software hot wallet, or a custodial hardware cold wallet. These are the most common types, but more combinations are possible.

Wallets made of software

Software wallets include desktop and mobile applications. These wallets are installed on a desktop or laptop computer and allow you to access your cryptocurrencies, conduct trades, view your balance, and do a variety of other things. Some software wallets additionally provide extra features, such as exchange integration if you use a wallet created by a Bitcoin exchange.

Many mobile wallets provide rapid payments at physical stores using near-field communication (NFC) or QR code scanning. Mobile wallets often work with iOS or Android handsets. Wallets such as Trezor, Electrum, and Mycelium are examples. In general, software wallets are hot wallets.

WARNING: You access your cryptocurrency via private keys. Your coins are accessible to anyone who has your private key.

Hardware Wallets

Hardware wallets are the most popular type of wallet because you can store your private keys and remove them from your device. These devices resemble USB drives, and modern hardware wallets include a variety of features. 

By connecting the hardware wallet to your computer or smartphone, you can conduct cryptocurrency transactions. Most of them can sign cryptocurrency transactions automatically without requiring you to enter the key, circumventing a hacker's ability to log your keypresses or record your screen.

These devices are frequently priced between $100 and $200. The hardware wallets Ledger and Trezor are both well-known. Because hardware wallets do not have an active connection until they are plugged in, they are considered cold wallets.

IMPORTANT: Some modern hardware wallets include Bluetooth connectivity to your device. Use these with caution because Bluetooth is a wireless signal that, when activated, can be accessed by unauthorized parties.

Wallets Made of Paper

Early cryptocurrency users would write or type their keys on paper, referring to them as paper wallets. These expanded to include keys and QR codes, allowing mobile wallets to scan them. However, because paper wallets are easily damaged or misplaced, many cryptocurrency owners no longer utilize them.

There is nothing wrong with using a paper wallet as long as you maintain it securely in a safe or deposit box and check on it now and then to verify it hasn't deteriorated.

Crypto Wallet Safety

Wallet security is critical because cryptocurrencies are valuable targets for hackers. Encrypting the wallet with a strong password, utilizing two-factor authentication for exchanges, and storing any substantial sums offline are other measures.

IMPORTANT: There have been numerous reports of spyware masquerading as wallets, so do your homework before picking which one to use.

Seed Phrases

The majority of contemporary wallets produce a 12-word mnemonic seed phrase. A sentence like "airport bedroom impression sample reception protection road shirt..." may appear arbitrary, yet your wallet creates and links it to your keys. If your wallet is lost or damaged, you can use the phrase to recover it. These words should be properly preserved in a secure location because anyone who discovers them will have access to your cryptocurrency.

Exchanges of cryptocurrencies

Custodial key storage is now available for users of cryptocurrency exchanges. However, you should exercise caution when using this service. For attackers, cryptocurrency exchanges are highly prized targets.

Furthermore, there are no guarantees that you will receive your cryptocurrency if the cryptocurrency exchange goes out of business. Coinbase, for example, stated in its quarterly filing to the Securities and Exchange Commission in May 2022 that

... custodial-held crypto assets may be considered bankruptcy estate property; in the event of a bankruptcy, the crypto assets we hold in custody on behalf of our customers may Customers who are subject to bankruptcy proceedings may be classified as our general unsecured creditors.

In a bankruptcy case, general unsecured creditors are ranked lower on the list of creditors. As a result, if there are insufficient assets to liquidate and meet financial obligations for higher-priority creditors, your crypto assets may be lost if your custodial wallet company declares bankruptcy.

The best Bitcoin key security procedures comprise withdrawing your keys from your wallet, storing them cold, and storing them in a vault, safe, or deposit box. The more steps you take to access your Bitcoin, the more difficult it is for a criminal to do so. In this manner, you can avoid losing your keys. It also assures that whoever you send your keys to does not misplace them or refuse you access to them.

What Is the Best Cryptocurrency Wallet?

There are numerous wallets to select from, each with its own set of features. It's advisable to read as many evaluations as possible to pick one that meets your requirements while keeping your keys safe.

What Is the Safest Crypto Wallet?

The safest crypto wallet has no connection on its own or to a device with internet access. It should also not refuse you access to your cryptocurrency because the custodian is having financial difficulties. Many ostensibly "safe" wallets contain wireless connection technology that determined cybercriminals can use.

Do I Need a Cryptocurrency Wallet?

Yes. You cannot access your cryptocurrency without your private keys and a blockchain interface. Although all wallets can store keys, only hot wallets can access the blockchain, therefore keep your keys off your hot wallet until you need them.
