What are Crypto Wallets and Why Do You Need One?

Crypto wallets are the tools that let you store and use cryptocurrencies. Learn how they work, what kinds of wallets are available, and how to keep your crypto assets secure while taking part in the crypto ecosystem.

If you’re planning to buy cryptocurrencies through a trading platform or exchange, you’ll need a crypto wallet first. These digital wallets or Crypto Wallets enable you to send, receive, and hold cryptocurrency. 

Crypto wallets, similar to bank accounts that carry fiat money (essentially any paper currency such as the Indian Rupee), store digital currencies such as Bitcoin and Ethereum. However, unlike typical bank accounts, not all crypto wallets are custodial. As a result, you may manage who has access to the funds by controlling who owns your private key.

Crypto Wallets Explained

A cryptocurrency wallet, often known as a crypto wallet, is a safe digital or hardware instrument that allows users to store, manage, and exchange cryptocurrencies. It does not physically store cryptocurrency, but rather the digital credentials needed to access and manage crypto assets on the blockchain, which is the fundamental process of cryptocurrencies.

It is crucial to keep in mind that cryptocurrency transactions do not represent the ‘sending’ of crypto tokens from one person’s mobile phone to another. When a user sends tokens, the transaction is encrypted by the user’s private key and released to the blockchain network. The network then incorporates the transaction in order to reflect the changed balance in both the sender’s and recipient’s addresses.

What are Crypto Wallets

As a result, the name ‘wallet’ is a bit misleading, because crypto wallets do not truly store crypto in the same way as physical wallets do. Instead, they read the public ledger to display the balances in a user’s address and hold the private keys that allow the user to conduct transactions.

Working of Crypto Wallets

Crypto wallets work by holding a pair of cryptographic keys – a public key and a private key. These keys are required in order to access and transfer cryptocurrencies.

◾Public and Private Keys: Your public key, akin to your bank account number, is a lengthy string of random numbers that can be safely shared with third parties, like cryptocurrency exchanges, without compromising your wallet’s security. This key enables cryptocurrency transactions.

Conversely, your private key must remain confidential as it grants access to your actual cryptocurrency on the blockchain. Unauthorized access to your private keys can lead to control over your digital assets.

◾Secure Storage: Crypto wallets come in two main types: software-based (online, mobile, desktop) and hardware-based (physical devices). Hardware wallets such as Ledger Nano S or Trezor are considered the most secure because they store private keys offline, reducing susceptibility to hacking.

◾Address Generation: When you wish to receive cryptocurrency, your wallet generates a unique receiving address derived from your public key. You share this address with the sender, who uses it to transfer funds to you.

◾Transaction Authorization: When you intend to send cryptocurrency, your wallet generates a digital signature for the transaction using your private key. This signature validates your ownership of the funds and authorizes the transfer.

◾Transaction Broadcast: The signed transaction is transmitted to the blockchain network, where it undergoes verification by network nodes (computers). Once confirmed, the transaction becomes part of the blockchain’s history by being added to a block.

◾Balance Monitoring: Wallets continuously monitor your cryptocurrency balance by scanning the blockchain for transactions associated with your public key. This allows you to track your digital asset holdings.

◾Access Security: To access your wallet and initiate transactions, you must provide your private key or a password (for software wallets). Hardware wallets often require physical confirmation, adding an extra layer of security.

Types of Crypto Wallets

There are two primary categories of cryptocurrency wallets: hot wallets, which are software-based and connected to the internet, and cold wallets, which are physical and offline. Keep reading to explore the various types of crypto wallets and determine which one suits your needs best.

Types of Crypto Wallets

◾Hot Wallets: These are online crypto wallets, making them more accessible but also more vulnerable to potential hacker attacks. Common examples of hot wallets encompass web-based wallets, mobile wallets, and desktop wallets. 

Hot wallets store private keys on the app itself, which poses security risks due to potential network vulnerabilities exploited by hackers or malware. While it’s generally discouraged to store large amounts of cryptocurrency in hot wallets, you can enhance security through stronger encryption or by using devices that safeguard private keys in a secure enclave.

Market participants often opt for a combination of hot and cold wallets based on their specific needs, given the diverse reasons for either connecting or disconnecting their cryptocurrency holdings from the internet.

◾Cold Wallets: These are offline crypto wallets, offering heightened security despite their reduced convenience. Cold wallets can take the form of physical objects like paper or engraved metal. 

Examples of cold wallets include paper wallets, where private and public keys are written or printed on a physical medium, and hardware wallets, external devices such as USB or Bluetooth accessories that store keys. 

Why Are Crypto Wallets Necessary?

Crypto wallets play a vital role in the operation and utility of cryptocurrencies. Here are some key reasons highlighting the importance of crypto wallets:

◾Asset Management: Crypto wallets empower users to oversee and control their cryptocurrency holdings effectively.

◾Transactions: The ability to send and receive cryptocurrency payments is a prominent feature provided by crypto wallets.

◾Interaction with Decentralized Applications (dApps): Utilizing Web 3.0 dApps necessitates the use of a crypto wallet.

◾Identity Verification: Cryptocurrencies are securely stored on blockchains, and these wallets facilitate transactions by associating usernames with public key addresses on the blockchain.

◾Key Management: Cryptocurrencies exist on the blockchain as public key addresses. Crypto wallets assist users in managing the private encryption keys required to access a specific address and initiate transactions.

Advantages & Disadvantages

Similar to any technology, crypto wallets have their own set of advantages and disadvantages:


◾Financial Control: Crypto wallets empower users with complete control over their funds, a capability not typically found in traditional banking systems.

◾Security: They offer a secure environment for safeguarding cryptocurrencies. Both hot and cold wallets incorporate various security features to protect your assets.

◾User-Friendly: Crypto wallets are relatively user-friendly, especially hot wallets.


◾Potential for Loss: Losing your private keys or hardware wallet results in the loss of access to your funds.

◾Hacking Risk: While crypto wallets generally prioritize security, they are not entirely impervious to hacking. Online wallets, in particular, can be susceptible to cyber threats.


Whether you’re a casual investor, a day trader, or a HODLer, having a trustworthy crypto wallet is crucial for handling your digital assets. While the security and usefulness of digital wallets have evolved substantially over the years, users must understand how they work and how to use them responsibly. 

Always keep your private keys safe, and only invest in cryptocurrencies that you understand and are willing to risk. Now that you know what a crypto wallet is and how it works, you can confidently traverse the world of cryptocurrency. Good luck with your crypto trading!
