What Is a Crypto Wallet? How It Works & If You Need One

  • A crypto wallet is a device or program that allows you to transfer and store cryptocurrencies.
  • There are different types of crypto wallets, such as paper wallets, hardware wallets, and software wallets.
  • The security of a crypto wallet depends on how the private key is stored.

You can’t fold a bitcoin and put it in your wallet. however, you can hold the keys to your crypto using your own crypto wallet.

quick tip: wallets have many public keys. this means you can provide multiple different public addresses and use them to receive crypto in the same wallet.

The important part of a wallet, and the part where new users often get into trouble, is the private key. a private key is like the key to a safe deposit box. anyone who has access to a wallet’s private key can take control of the balance stored there.

but unlike a safe deposit box, crypto users who have their own private keys and transact using non-custodial wallets (i.e. a wallet that is not hosted by an exchange or other third party) become your own bank.

“It’s similar to a bank account, but the main difference is that it’s controlled by a key that only you control. You use this [private] key to initiate transactions, which is called a ‘signature,'” says joel dietz, founder of art wallet and contributing developer of metamask.

While the idea of ​​cryptocurrency itself is new to many people, cryptocurrency wallets are designed to be easy to use. web wallets like metamask and desktop wallets like electrum come with a graphical user interface (gui) that is designed to be as simple as possible.

understand how crypto wallets work

blockchain is a public ledger that stores data in what are known as “blocks”. These are records of all transactions, the balances held at any given address, and who holds the key to those balances. crypto is not stored “in” a wallet, per se. Coins exist on a blockchain and the wallet software allows you to interact with balances held on that blockchain. the wallet itself stores addresses and allows its owners to move coins elsewhere, while also allowing others to see the balance held at any given address.

quick tip: When sending a crypto transaction, always make sure you send it to an address for a wallet of the same type of cryptocurrency. if you send bitcoin (btc) to a bitcoin cash (bch) address, for example, those funds will be lost forever.

“Most cryptocurrency wallets allow users to send, receive and store cryptocurrency. Some have a function to buy and spend cryptocurrency,” says utsav dar, co-founder of incub8 finance. “Certain crypto wallets have additional features such as swapping between tokens, staking tokens for a fixed return paid to users, as well as access to dapps (decentralized applications) built on various networks.”

While each wallet has its own specific nuances, here are the general steps required to send or receive funds using a crypto wallet:

  • To receive funds, you must retrieve an address (also known as a public key) from your wallet. Locate the “generate address” feature in your wallet, click on it, then copy the alphanumeric address or qr code and share it with the person you want to send crypto to.
  • to send funds, you need the address of the receiving wallet. Locate the “send” function on your wallet and enter a wallet address you want to send coins to. select the amount of cryptocurrencies you want to send and click “confirm”. consider sending a small test transaction before sending large amounts of cryptocurrency. Please note that sending coins requires a fee to be paid to miners in exchange for processing the transaction.

Sending money via qr codes or long strings of numbers and letters may seem strange at first. but after doing it a few times, the process becomes quite simple.

types of crypto wallets

Cryptocurrency wallets fall into two general categories: software wallets and hardware wallets.

Software wallets are simply desktop programs or browser extensions that make it easy for people to send, receive and store cryptocurrency. hardware wallets serve a similar purpose, but are physical devices that can be plugged into a computer.

software wallets are sometimes called “active” wallets because the funds are held online. hardware wallets keep private keys offline or in “cold” storage.

hardware wallets

A hardware wallet is a small device that can store crypto offline. “A hardware wallet keeps your keys off your phone or computer,” Dietz says. “Usually you connect the hardware wallet from a USB port. This is much more secure because all the signing is done outside of your computer.”

The typical hardware wallet costs around $100, give or take. these tend to be a bit more complicated to use than software wallets.

Most hardware wallets interact with a computer in one of three ways:

  • a web-based interface
  • a company-built application
  • a separate software portfolio

software wallets

A software wallet is a computer program or mobile application that stores private keys online. software wallets are unique to each cryptocurrency, while hardware wallets often support multiple currencies (more on these differences later).

“[software wallets] can be used on the web, in which case they are custodial wallets, which are not completely secure. or [they can come] in the form of apps that can be installed on a phone/laptop, in which case the private keys are stored on the local device,” says dar. “These may be connected to the internet, which again makes them less secure.”

​​Quick Tip: When using software wallets, be sure to create backups on a regular basis. If a problem occurs with your web browser or hard drive, you could lose your wallet’s private keys, resulting in a permanent loss of funds.

The three main types of software wallets are:

  • web-based wallets, such as metamask, that work as a browser extension and can send eth transactions, making it easier for users to interact with things like decentralized applications and decentralized finance (defi ) protocols
  • desktop wallets, such as the electrum wallet, which can be used on a desktop or laptop
  • mobile wallets , such as the blockchain.com wallet, which allows users to store crypto, send/receive transactions, and “sweep” private keys from an existing in-app wallet by scanning a qr code on their smartphones

Each type of crypto wallet has its own use case depending on the user’s goals, although they all achieve the same thing.

quick tip: paper wallets are another way to store your private keys. But creating and using paper wallets carries a high risk of user error and is too dangerous to store a significant amount of crypto. it is generally recommended to use other types of crypto wallets.

pros and cons of crypto wallets

some advantages of using non-custodial crypto wallets include:

  • self-ownership of money. if you have your own private keys, then that crypto belongs to you and you alone. by comparison, money in a bank is technically the property of the bank.
  • the ability to send transactions to whomever you want, whenever you want. decentralized cryptocurrencies are censorship resistant because no one controls the network, making it difficult for anyone to stop transactions.

some drawbacks of using crypto wallets include:

  • user responsibility. becoming your own bank means you have to take 100% responsibility for anything that goes wrong.
  • learning curve. Using a crypto wallet requires a basic level of computer skills, as well as becoming familiar with a new kind of financial ecosystem.

the end result

the answer to the question “what is a crypto wallet?” is that it is like a crypto bank account that only you control. software wallets are designed for convenience, while hardware wallets are designed for security. To get started, you need to research what types of wallets work best for you. research the options available to you, including cost and safety.

Those interested in going one step further can invest in a hardware wallet, as doing so is one of the best ways to take ownership of your own private keys. learning how to use them may take a bit longer for beginners, but doing so might be worth the added security. For those who have large sums of money in the form of cryptocurrencies, most experts agree that using a hardware wallet is a must.
