What is a wallet in the cryptocurrency industry? And what role does it play? As puts it, wallet is a service that allows cryptocurrency users to store and retrieve their digital assets. Similar to your personal wallets or bank lockers (hardware devices) where you keep your cash, credit cards, and jewelry among other sensitive items.

In the crypto world, there are primarily two types of wallets – Hot wallets and cold wallets. Hot wallets are those that are connected online or in other words, to the internet like software wallets. Cold wallets are those that are ‘disconnected’ from the internet which is typically hardware devices. You might wonder why someone would need a hardware or physical device to store digital assets? Keep reading.

What is a Crypto Wallet?

What is crypto wallet is an essential tool for managing and using cryptocurrency. They provide a way for users to access and interact with the blockchain, the distributed ledger that powers cryptocurrency transactions. Cryptocurrency wallets store two important pieces of information: public keys, which are used to identify a user’s address on the blockchain and receive cryptocurrency, and private keys, which are used to sign and broadcast transactions to the blockchain.

Cryptocurrency wallets can take many different forms, including software wallets that are installed on a user’s computer or mobile device, and hardware wallets that are stored on a separate physical device, such as a USB drive. Some wallets are designed to hold a single cryptocurrency, while others support multiple cryptocurrencies.

One important thing to note when you think ‘what is crypto wallet?’ is that they do not actually store cryptocurrency in the same way that a physical wallet stores cash. Instead, they read the public ledger to show users the balances in their addresses, and they use the private keys to enable users to sign and send transactions on the blockchain. This means that if you lose your private key, you may lose access to your cryptocurrency permanently.

In addition to basic features like sending and receiving cryptocurrency, the best crypto wallets offer additional functionality. For example, some wallets allow users to buy and sell cryptocurrency, or to interact with decentralized applications (dApps).

How Do Cryptocurrency Wallets Work?

Cryptocurrency wallets work by storing users’ private and public keys, which are used to identify the user’s address on the blockchain and receive cryptocurrency, and to sign and broadcast transactions, respectively.

When a user wants to send cryptocurrency to another person, they use their private key to sign a transaction and send it to the blockchain network. The transaction includes the amount of cryptocurrency being sent, the address of the recipient, and the address of the sender. The network then verifies the transaction and, if it is valid, adds it to the blockchain and updates the balances of the sender and the recipient.

Users can view the balance in their cryptocurrency wallets by accessing the public ledger, which is a record of all transactions on the blockchain. The wallet uses the user’s public key to look up the balance in the ledger and display it to the user.

It’s important to note that while crypto wallets provide a convenient interface for interacting with the blockchain and managing cryptocurrency, they do not actually store cryptocurrency in the same way that physical wallets store cash. Instead, they simply provide access to the user’s keys and the ability to read and update the public ledger.

Why are Crypto Wallets Important?

Now we know ‘what is crypto wallet?’ But why are they important? Crypto wallets are important because they provide a secure method for storing cryptocurrency. When you store your cryptocurrency on an exchange, you are relying on the exchange to keep it safe. However, exchanges can be vulnerable to hacking and other security breaches, and if your crypto is stolen or lost, you may have no way to recover it.

On the other hand, when you store your crypto in a wallet, you retain ownership of your private keys and have full control over your finances. This is particularly important for larger amounts of cryptocurrency, as it allows you to keep your funds safe and secure.

What are the Different Types of Crypto Wallets?

Cold WalletHot Wallet
Cold wallets are kept offlineHot wallets are connected to the internet
Best suited to those storing a large amount of crypto over a large period of timeBest suited to beginners or regular traders who need to make quick, online payments
Reduced threat from hacking and online attacksVulnerable to hacking and online threats
Less convenient and more expensiveEasy and convenient to use
Examples: Paper wallets and hardware walletsExamples: Web-based wallets, mobile wallets, and desktop wallets

1. Cold Wallet

Hardware wallets are considered the safest among crypto wallets. They offer cold storage for your crypto assets since they are disconnected from the internet. ‘Ledger’ and ‘Trezor’ are the most widely used hardware wallets and they look similar to USB drives. You would connect your hardware wallets to the internet to transfer funds in and out of the wallet. Storage is offline but the data gets synced with the underlying Web 3.0 technologies like blockchain when you connect online to make transfers. For the most part, your digital assets will remain offline and you will not have to worry about online hacks and rug pulls (where the custodian runs away with your money).

2. Hot Wallet

Hot wallets include your wallets on centralized and/or decentralized service providers. Wallets on crypto exchanges like Binance and Coinbase are examples of centralized hot wallets. Your Demat account that holds your equity stocks can be considered as a centralized hot wallet. Further, wallets such as Metamask, Trust Wallet, and Phantom are examples of decentralized wallet services. 

One of the core objectives of cryptocurrency and Web 3.0, in general, is to enable people to be their own banks without relying on third parties. No third party should be bothered about what you do with your funds as long as they are used for legitimate purposes. Those who are averse to centralized services (and cold wallets due to their disadvantages) have a good alternative in decentralized hot wallets.

Custodial WalletsNon-Custodial Wallets
A custodian of a third party has control of the private keys and fundsUsers have complete control of their private keys and their funds
Less secure as funds are stored online and are therefore vulnerable to hackingMore secure as users hold their private keys offline
Less personal responsibility but requires trust in the custodian that holds user fundsUsers are wholly responsible for keeping their funds and private keys secure
Backups in place so if users lose their private keys, they can easily regain access to their walletIf users lose their private keys or recovery phrases, then they lose access to their funds
Lengthy KYC and AML proceduresNo KYC or AML procedure
More user-friendlyLess user-friendly
Best suited to beginners just starting outBest suited to those who want to retain full control of their funds

1. Custodial Wallets

Custodial crypto wallets, which are commonly provided by cryptocurrency exchanges, are known for their ease of use and are popular with both novice and experienced traders. They differ from non-custodial wallets in that the user does not have full control over their tokens and the private keys needed to make transactions are held only by the exchange. 

This means that the user must trust the exchange to handle their tokens securely and implement measures such as two-factor authentication and biometric authentication to prevent unauthorized access. Exchanges may also transfer a portion of the funds to a cold wallet to protect them from online attacks. However, users must set up these security measures before being able to make transactions.

2. Non-Custodial Wallets

Non-custodial crypto wallets allow users to retain full control over their funds because the private key is stored locally on their devices. When setting up a non-custodial crypto wallet, the user is given a list of 12 randomly generated words, known as a recovery phrase or seed phrase, which can be used to generate the public and private keys for the wallet. 

It is important to securely store this phrase as anyone with access to it can gain control of the funds in the wallet. If the phrase is lost, it may be difficult or impossible to recover the funds. Hardware wallets are a type of non-custodial wallet that store the private keys on the device itself, while software-based non-custodial wallets also give users full control over their keys and funds. However, this also means that users must take responsibility for the security of their passwords and recovery phrases.

Additional Types of Crypto Wallets

1. Multi-Signature Wallets

Multisignature (or multisig) crypto wallets are a type of cryptocurrency wallet that requires more than one private key to authorize a transaction. This means that multiple people, or multiple devices, must sign off on a transaction before it can be completed. 

For individuals, using a multisig crypto wallet can provide an extra layer of security. If a user loses one of their private keys, there will still be other keys that can sign transactions, so the user will not lose access to their entire wallet. 

Multisig crypto wallets can also be useful for organizations such as hedge funds, exchanges, and corporations. By requiring multiple keys to sign off on transactions, it becomes much more difficult for any one individual to make unauthorized transactions. This can help prevent fraud and the misuse of funds.

2.NFT Wallets

An NFT crypto wallet is a secure place to store non-fungible tokens (NFTs). There are two main types of NFT wallets: hardware wallets and software-based wallets. When choosing an NFT wallet, you should consider factors such as compatibility with NFT marketplaces, strong security measures, a user-friendly interface, availability on multiple devices, and cross-chain compatibility. 

Hardware crypto wallets, such as those made by Ledger and Trezor, are popular options, but they may not natively support NFTs, so you may need to connect them to a hot wallet that can store and manage NFTs.

3. DeFi Wallets

DeFi crypto wallets are cryptocurrency wallets that are specifically designed for use in decentralized finance (DeFi). DeFi is a sector of the cryptocurrency industry that focuses on financial products such as lending, saving, and more, which do not rely on a central broker. 

DeFi crypto wallets allow users to interact with DeFi products and manage their cryptocurrency holdings, typically on a mobile app or browser extension. These wallets may have features such as support for a wide range of tokens and blockchains, the ability to view and manage non-fungible tokens (NFTs), and options for earning passive income through staking cryptocurrencies. Some DeFi wallets may also have additional security features, such as two-factor authentication, to protect user funds.
