What Is a Crypto Wallet? (Plus How to Create and Use One)

Similar to a bank account in the traditional finance industry, a crypto wallet is a crucial element of your journey into the exciting world of cryptocurrencies. In fact, a cryptocurrency wallet is probably the first thing you will create when getting started with digital assets.

In this article, we will explain what crypto wallets are, how they work, and describe their main types. A crypto wallet is a tool — a software program that is sometimes accompanied by a hardware device — that allows you to interact with the underlying blockchain network. From a more practical perspective, a cryptocurrency wallet allows you to send, receive, and store digital assets. However, unlike bank accounts, most crypto wallets allow you to maintain full control over your funds by managing both your private and public keys to your wallet.

Blockchain networks , the underlying technology powering cryptocurrencies, use public-key cryptography to encrypt data and protect users. Cryptographic technology has two crucial elements: the private key and the public key. With public-key cryptography, the sender uses the public key to encrypt data, while the recipient utilizes his private key to decrypt the information. In terms of cryptocurrencies, the public key refers to your wallet address, which you are safe to share with anyone. On the other hand, you use your private key to create digital signatures and verify transactions.

For better understanding, think of the public key as your bank account number and your private key as your login credentials to your online banking platform.

Sharing your account number allows you to receive funds from others. However, if you do the same with your login credentials, cybercriminals and malicious parties will try to gain access to your funds. For example, while custodial solutions manage your private keys, others offer you full control over your funds. Also, some wallets allow users to interact with only one cryptocurrency.

In contrast, other crypto wallet services provide all-in-one solutions in which you have access to numerous coins and multiple integrated decentralized applications DApps.

With that said, the core functions of all cryptocurrency wallets are based on public-key cryptography. For that reason, they use the same process for sending and receiving digital assets, like in the following example:. In addition to the above, some more advanced cryptocurrency wallets provide additional features to their users, such as:. As mentioned earlier, there are multiple types of cryptocurrency wallets present on the market, which we will explore in this section.

Examples: Binance , Coinbase , Bitfinex. As their name suggests, custodial wallets store your private keys in their custody, meaning that you are not in full control over your funds, but the service provider is. This structure is similar to what financial institutions use to manage your funds in your bank account. In the crypto space, the most popular use-cases for custodial wallets are centralized exchanges, in which the service provider manages the funds of their users.

As a result, they can usually offer a better trading experience to their users as they have access to more liquidity while matching buyers with sellers more efficiently. This is especially useful when you seek to avoid transfers in congested blockchain networks that are infamous for their excessively high transaction fees and long processing times. Also, as the service provider controls the private keys, they are responsible for solving issues with transfers related to wallets on their platform.

Furthermore, in exchange for providing a custodial solution, some service providers offer specific guarantees or protections against security incidents, fraud, or other less fortunate events that could negatively impact your cryptocurrencies.

Also, with custodial wallets, you have to trust the service provider that it manages your funds properly, without the risk of losing your digital assets due to exit scams or bankruptcy. For these reasons, custodial wallets are often seen as the least secure option to store cryptocurrencies. Moreover, some exchanges use higher fees for withdrawals than for standard wallet-to-wallet transfers to protect themselves from losses, increasing the costs for users.

With non-custodial wallets, you are in full control of your private keys and your cryptocurrencies. They feature better security than their custodial counterparts, especially if you follow the best practices of storing your coins safely in your wallet we will talk about this later. Also, most non-custodial wallets allow you to set your own fees for crypto transactions, which you can use to speed up transfers or decrease processing costs. On the other hand, many non-custodial wallets lack the ability to connect natively to other services.

To access them, you have to transfer your digital assets to external wallets. Examples: Exodus , Atomic Wallet , Electrum. Desktop wallets are software solutions that you download and install on your computer to store cryptocurrency. Desktop wallets encrypt your private key with your password.

No one can access your cryptocurrency holdings unless they successfully log into your wallet or acquire your seed phrase. Also, most desktop wallets support multiple platforms, meaning that you can access your cryptocurrency holdings from mobile, tablet, and other devices as well. On the flip side, desktop wallets are hot wallets, which means that they are connected to the internet most of the time.

Due to the continuous online connection, desktop wallets are considered less secure than cold wallets that stay disconnected from the web. Similar to desktop wallets, mobile wallets are also software-based solutions that allow you to store cryptocurrency. Since you can carry your smartphone anywhere you go, mobile wallets provide continuous access to your cryptocurrencies.

As a result, you can scan a QR code or tap your phone against a terminal instead of manually typing or copy-pasting a wallet address to send funds to someone or pay for a product. While this feature makes it convenient to transfer crypto, it also minimizes the chance of sending funds to other wallets than you have originally intended to. Also, almost all mobile wallets provide two-factor authentication features to users, allowing them to store their funds more securely. Like some desktop wallets, many service providers offer you the option to sync your mobile wallet with other devices.

On the flip side, similarly to desktop wallets, mobile wallets are also continuously connected to the internet. Note that unless you have biometric security e.

Examples: Blockchain. Online wallets are software-based crypto wallets that are operated via a cloud server, allowing users to interact with their digital assets by simply opening the platform via their web browsers. Web wallets are convenient for users as they can access their cryptocurrency holdings basically from any device with an internet connection. With that said, multiple service providers have addressed the issue by implementing security measures, such as implementing multisignature technology into online wallets.

Multisig web wallets provide additional security to users as they require multiple signatures — one from the service provider and one from the customer — in order to move funds. However, online wallets require a constant connection to the internet, which decreases their overall security.

Examples: Ledger , Trezor , KeepKey. Hardware wallets are considered the most secure solutions currently on the market to store cryptocurrency. With a hardware wallet, your private keys are stored on a secure physical device, which only connects to the internet when you use it to transfer funds. For that reason, such crypto storage solutions are called cold wallets.

To access your digital assets on the hardware wallet, you have to plug the physical device like a pen drive into your computer, entering a PIN on the device to unlock it. You also have to provide your PIN via the device every time you seek to move funds to another wallet. Still, they also have to acquire the physical device to steal your cryptocurrencies, which is a highly unlikely scenario.

Hardware wallets support numerous often over 1, cryptocurrencies, allowing users to store a diversified digital asset portfolio using a single device. While hardware wallets provide excellent security to users, they cost money, and the initial setup can be challenging.

Examples: Bitcoin. As its name suggests, a paper wallet is a piece of paper on which users can print their public and private keys. Most paper wallets include the keys as both alphanumeric strings and QR codes for scanning via a smartphone. To create a paper wallet, users can utilize a free service that automatically generates a BTC address on the Bitcoin blockchain. As the final step, the user prints out his private and public keys on a piece of paper.

Like with other crypto wallets, users can share their public keys to accept digital asset transactions. To send cryptocurrency, the user has to load his private keys via a software wallet by either manually typing it or scanning the QR code. Since the private keys are printed on paper and stored in a physical form, paper wallets are a form of cold wallets that can effectively protect users from hackers.

Despite their cold storage-related benefits, experts recommend most users to avoid keeping their crypto holdings on paper wallets. Instead, you have to transfer all your paper wallet balance to another wallet before sending your recipient a partial transaction.

If you fail to do so, you could lose a significant share of your crypto holdings. Warning: One of the most popular paper wallets, BitcoinPaperWallet. In addition to BitcoinPaperWallet. Web 3 or DeFi wallets are the newest types of cryptocurrency wallets, allowing users to connect their wallets and interact with numerous decentralized applications. DeFi wallets are software-based, with most of them offering support for multiple platforms, such as desktop, mobile, and web.

Suppose users seek to explore the decentralized finance space. In that case, they can connect their Web 3 wallets natively via their browsers or via WalletConnect by scanning the QR code of a DeFi application with their mobile wallet via their smartphone cameras.

As a result, in addition to basic functionality like receiving, sending, transferring, and paying with crypto, users can access numerous other DeFi activities. Examples include lending and borrowing, yield farming, staking, exchanging, and swapping digital assets. While web 3 wallets are continuously connected to the internet, some of them have implemented advanced security measures, such as guardians. Unlike traditional crypto wallets that use a seed phrase for recovery, guardians are people you know and trust that are responsible for recovering your wallet and approving transactions that have exceeded your limits.

Generally, cryptocurrency wallets from legit service providers are considered safe in the digital asset community. Cryptocurrency wallet features differ not just by the type of the wallet but also by the actual solution. For that reason, we have collected the most important features to look for to select the crypto wallet that best suits your interests:.

Creating a non-custodial crypto wallet works a bit differently. We have outlined the actual steps to set a non-custodial software wallet below:. Like bank accounts in the traditional finance space, crypto wallets represent your own hub in the digital asset world. You use your cryptocurrency wallet to send, receive, hold, and pay with coins, with some solutions offering additional functionalities, such as external app integrations and built-in features.

Crypto wallets have multiple types, with each offering a different level of security, convenience, as well as features. While digital asset wallets from trusted service providers are considered safe, you should always do your own diligence and use the best practices of holding coins to stay secure in the crypto space.

If you have the budget, consider purchasing a hardware wallet from the manufacturer or a certified reseller, as it is currently the safest solution to store cryptocurrency. Since they provide cold storage solutions without being continuously connected to the internet, hardware wallets are considered the safest cryptocurrency wallets.

The wallets are disconnected, and the burden is on either the holder or the verifier to request all required information for each transaction.

Signing can for example result in executing a smart contract , a cryptocurrency transaction see "bitcoin transaction" image , identification or legally signing a 'document' see "application form" image. A crypto currency wallet works by a theoretical or random number being generated and used with a length that depends on the algorithm size of the cryptocurrency's technology requirements. The number is then converted to a private key using the specific requirements of the cryptocurrency cryptography algorithm requirement. A public key is then generated from the private key using whichever cryptographic algorithm requirements are required. The private key is utilised by the owner to access and send cryptocurrency and is private to the owner, whereas the public key is to be shared to any third party to receive cryptocurrency.
