TLDR - A Comprehensive Guide to Crypto Wallets and Their Importance

A crypto wallet, also known as a cryptocurrency wallet, is a crucial digital tool designed for securely storing, sending, and receiving cryptocurrencies. It operates by interfacing with blockchain networks, allowing users to manage their digital assets effectively. There are different types of crypto wallets available, including hot wallets and cold wallets. 

Additionally, hardware wallets and software wallets offer unique features and benefits. Whether you prefer self-custody or seeking the best Web3 wallet, understanding the differences between these wallet types is essential. Moreover, crypto wallets play a significant role in the cryptocurrency ecosystem, raising the question of how they generate revenue.

A. Crypto Wallets: Types, Function, and Revenue Streams

What is a Crypto Wallet?

A crypto wallet is a digital tool that enables users to securely store, send, and receive cryptocurrencies. It functions by interacting with blockchain networks, providing users with an interface to manage their digital assets. Crypto wallets come in various types, such as hot wallets, cold wallets, hardware wallets, and software wallets, each with its own set of advantages and drawbacks.

How Do Crypto Wallets Make Money?

Exchange Fees and Transaction Fees

Crypto wallets make money through a variety of avenues. One such method is by charging exchange fees and transaction fees, like BitGo, a multi-signature wallet designed for corporate use. BitGo offers secure custody of funds and charges approximately 0.25% for any incoming or outgoing transaction. This service is tailored for companies seeking a reliable third-party custodian rather than individual users.

Staking and Interest

Wallets that support staking allow users to earn passive income while holding cryptocurrencies, with the wallet provider typically taking a small fee or commission.

Partnerships with Other Crypto Projects

Crypto wallets also generate income through partnerships by publishing advertisements or earning via affiliate links. A popular example is the integration of coin-swapping services like Shapeshift or Changelly, which offer attractive partner programs due to their higher-than-average market rates.

B. Wallet Types

Hot Wallets: A Closer Look

1. Software Wallets

Software wallets are applications installed on your computer or mobile device. They provide easy access to your crypto assets but are more vulnerable to hacking compared to other wallet types.


  • Easy to use
  • Accessible from your device
  • Supports multiple cryptocurrencies


  • Vulnerable to hacking
  • Dependent on the device’s security

2. Mobile Wallets

Mobile wallets are specifically designed for smartphones, offering on-the-go access to your cryptocurrencies. They are perfect for everyday transactions but can be susceptible to hacking or device loss.


  • Portable and convenient
  • User-friendly interface
  • Supports in-app transactions


  • Less secure than other wallet types
  • Risk of losing access due to device loss or theft

3. Desktop Wallets

Desktop wallets are software wallets installed on your computer, offering a balance between convenience and security. They are more secure than mobile wallets but still face potential hacking risks.


  • Better security than mobile wallets
  • Supports a wide range of cryptocurrencies
  • Accessible from your computer


  • Still vulnerable to hacking
  • Limited to one device

4. Web Wallets

Web wallets are accessible through a web browser, making them a convenient option for managing your cryptocurrencies. However, they are more susceptible to phishing attacks and hacking attempts.


  • Accessible from any device with a web browser
  • Easy to use
  • Supports multiple cryptocurrencies


  • Vulnerable to phishing attacks
  • Lower security than other wallet types

Cold Wallets: The Ultimate in Security

1. Hardware Wallets

Hardware wallets are physical devices that store your private keys offline, providing maximum security against hacking attempts. They are considered the safest wallet type for storing large amounts of crypto assets.


  • Exceptional security
  • Stores private keys offline
  • Resistant to hacking attempts


  • More expensive than other wallet types
  • Less convenient for daily transactions

2. Paper Wallets

Paper wallets are a simple, low-tech option for storing your private keys on a physical piece of paper. While they offer good security, they require careful handling and storage to avoid damage or loss.


  • Inexpensive and easy to create
  • No risk of digital hacking
  • Stores private keys offline


  • Can be damaged or lost easily
  • Less convenient for regular transactions

C. Custodial vs. Non-Custodial Wallets

Custodial Wallets

Custodial wallets entrust your private keys to a third party, usually a cryptocurrency exchange or wallet service. While they offer convenience, they are less secure than non-custodial wallets.


  • User-friendly
  • Access to additional services (e.g., trading, staking)
  • Easy recovery of lost passwords


  • Less secure due to third-party control
  • Risk of losing assets if the provider is hacked

Non-Custodial Wallets

Non-custodial wallets, also known as self-custody wallets, allow you to maintain control of your private keys. They offer greater security but can be more challenging to use, especially for beginners.


  • Greater control over your assets
  • More secure than custodial wallets
  • No reliance on third-party providers


  • Less user-friendly
  • Limited access to additional services

D. Which Type of Wallet is More Secure?

In general, cold wallets (hardware and paper wallets) offer the highest level of security, followed by non-custodial hot wallets (desktop and mobile wallets). Custodial wallets and web wallets are the least secure options due to their reliance on third parties and vulnerability to online threats. However, the choice of wallet type depends on your individual needs, preferences, and risk tolerance.

For those who prioritize security and store large amounts of cryptocurrency, a cold wallet like a hardware wallet is the best option. On the other hand, if you require frequent access to your crypto assets for daily transactions, a non-custodial hot wallet (e.g., desktop or mobile wallet) might be more suitable.

It’s important to note that using a combination of wallet types can provide an optimal balance between security and convenience. For instance, you can store the majority of your digital assets in a cold wallet for long-term holding and keep a smaller portion in a hot wallet for daily transactions and trading.

E. The Rise of Self-Custody Wallets

Self-custody wallets have recently gained significant attention as an innovative solution for securely managing digital assets. These wallets empower users to maintain control of their private keys, ensuring a higher level of security compared to custodial wallets.

The Importance of Self-Custody Wallets

The increasing need for self-custody wallets arises from tighter regulations on crypto services, leading to some exchanges announcing the closure of their platforms and leaving users in confusion about where to store their assets. Moreover, there is a growing number of high-profile hacks, exploits, and fraud cases in the ecosystem, such as the FTX incident which caused a lot of users to lose access to their cryptocurrencies on the exchange. As the crypto landscape continues to evolve, self-custody wallets offer a greater sense of security and control.

Seedless Self-Custody: The Next Frontier

One of the latest developments in self-custody wallet technology is the introduction of seedless wallets. These wallets come in several different types, each with its own set of pros and cons.

Conventional (HD) Wallets

Hierarchical deterministic (HD) wallets are a type of self-custody wallet that uses a single seed phrase to generate multiple addresses. This allows for greater privacy, as users can generate a new address for each transaction. However, reliance on a single seed phrase can be a double-edged sword, as losing the seed phrase could result in losing access to all assets stored in the wallet. An example of a conventional (HD) wallet is Ledger Nano S.

MPC Wallets

Multi-party computation (MPC) wallets represent a breakthrough in cryptocurrency wallet development. These wallets use advanced cryptography to distribute private key management among multiple parties, increasing security without compromising usability. By eliminating the single point of failure present in conventional wallets, MPC wallets offer enhanced protection against hacks and theft. The main drawback, however, is their complexity, which could make them less user-friendly for crypto newcomers. An example of an MPC wallet is ZenGo.

Smart Contract Wallets

Smart contract wallets leverage the power of blockchain technology to enable advanced features and security measures. These wallet types can interact with decentralized applications (dApps) and DeFi platforms, making them the best web3 wallet option for those looking to participate in the expanding DeFi ecosystem. Additionally, smart contract wallets can implement multi-signature security, further reducing the risk of theft. The downside is that these wallets may have higher gas fees due to the use of smart contracts and can be more complex to set up and manage compared to traditional hot and cold wallets. An example of a smart contract wallet is Safe.

As the world of cryptocurrencies continues to evolve, self-custody wallets are proving to be an essential tool for safeguarding digital assets. By understanding the benefits and drawbacks of various wallet types, users can make informed decisions about which self-custody wallet best suits their needs.

F. The Guide for the Right Web3 Wallet

When selecting the ideal web3 wallet, it’s essential to consider various factors that align with your needs, preferences, and security requirements. Here’s a detailed guide on the different factors you should evaluate when choosing a web3 wallet:

Security Features

The security of your digital assets should be a top priority when choosing a wallet. Look for wallets that offer robust security measures, such as:

  • Two-factor authentication (2FA)
  • Multi-signature support
  • Biometric authentication (fingerprint, facial recognition)
  • Regular updates and patches
  • Encrypted private keys and seed phrases

User Experience

A user-friendly interface and seamless experience are essential for managing your cryptocurrencies efficiently. Consider the following aspects:

  • Intuitive design and layout
  • Easy navigation and functionality
  • Quality of customer support
  • Availability of tutorials and guides
  • Compatibility with your preferred device(s)

Supported Cryptocurrencies

Ensure that the wallet you choose supports the cryptocurrencies you own or plan to invest in. Some wallets support only a limited number of coins and tokens, while others provide more extensive support. Also, look for wallets that are compatible with multiple blockchains and can accommodate various tokens and DeFi protocols.

Wallet Type

Consider the type of wallet that best suits your needs, taking into account factors like accessibility, convenience, and security. Here are the main wallet types:

  • Hot wallets (software, mobile, desktop, and web wallets): Offer convenient access to your cryptocurrencies but may be less secure due to being connected to the internet.
  • Cold wallets (hardware and paper wallets): Provide enhanced security by storing your private keys offline but may be less convenient for frequent transactions.

Custodial vs. Non-Custodial

Decide whether you prefer a custodial or non-custodial (self-custody) wallet:

  • Custodial wallets: Your private keys are managed by a third-party service, which may simplify the user experience but at the cost of reduced control and security.
  • Non-custodial wallets: You retain control over your private keys, offering greater security and independence at the expense of a potentially steeper learning curve.

Integration with DeFi Platforms

If you’re interested in participating in decentralized finance (DeFi) activities, look for wallets that offer seamless integration with popular DeFi platforms, allowing you to access lending, borrowing, staking, and yield farming services directly from your wallet.

Backup and Recovery Options

Ensure that the wallet you choose provides a reliable backup and recovery mechanism to safeguard your assets in case you lose access to your device or forget your password. Most wallets offer seed phrases or mnemonic phrases as a recovery tool, while some also support secure cloud backups.

Community Trust and Reputation

Research the wallet’s reputation and track record by exploring user reviews, expert opinions, and community discussions. A wallet with a solid reputation and a history of reliability and security is more likely to protect your assets.


Some wallets charge fees for certain transactions, such as exchanging one cryptocurrency for another or transferring funds to an external wallet. Compare the fees and weigh them against the wallet’s features and benefits to determine if it’s the right fit for you.

By considering these factors and evaluating your unique requirements, you can make an informed decision on the best web3 wallet for managing your digital assets securely and efficiently.

H. Wallet Security Tips

The Importance of Wallet Security

In a recent incident, Tay, a member of the MetaMask team, reported a massive wallet-draining operation that siphoned off over 5,000 ETH, along with numerous tokens and NFTs from crypto investors since December 2022. This highlights the need to avoid keeping all your assets under a single key or secret phrase for extended periods.

Tips for Improving Wallet Security

  1. Never Share Your Secret Recovery Phrase: It’s essential to keep your wallet’s secret recovery phrase confidential and not share it with anyone, including trusted individuals. Never engage with apps or people that require your wallet’s recovery phrase.
  2. Your Wallet App/Extension Should Always Be Official: As a precaution, always ensure that you download the official wallet app or extension from the provider’s website. For browser extensions, avoid downloading from third-party sources. Check the developer information and reviews of the app before downloading it. If in doubt, reach out to the provider for confirmation.
  3. Get Support Via Official Channels: Seek support only through official channels. Customer support may not be quick enough, but asking for help on social media or unofficial platforms can put you at risk of falling prey to scammers.
  4. Implement Two-Factor Authentication (2FA): Enable 2FA for all your accounts, including your crypto wallet, to add an extra layer of security.
  5. Diversify Between Hot and Cold Wallets: Use a cold wallet for long-term holdings, while keeping a hot wallet for active assets intended for DeFi or trading purposes.
  6. Secure Seed Phrases and Private Keys: Store your seed phrase and private keys in a safe place, like a hardware wallet or an offline location. Avoid relying on password managers, as they can be vulnerable to hacking, like Lastpass’ breach last year.
  7. Strengthen and Rotate Passwords: Use strong, unique passwords for your wallet and update them regularly to reduce the risk of unauthorized access.
  8. Stay Vigilant Against Phishing Scams: Be cautious when clicking links or downloading software, and avoid suspicious content to protect your wallet from potential threats.
  9. Monitor Your Wallet Activity: This will help you identify unusual or unauthorized transactions. For such tasks, you can use wallet extensions like Wallet Guard. Remember to revoke old and rarely used smart contracts, using built-in features in wallet apps like Debank’s Rabby or doing it directly with tools like, Unrekt, or blockchain explorers’ Token Approvals.
  10. Use Alternative Devices: Consider using a dedicated device or virtual machine for managing your crypto wallets, separate from your regular devices.
  11. Consider Multi-Sig Wallets: For added security, explore using a hardware wallet in conjunction with a multi-sig wallet, so even if one key is compromised, your funds remain protected.
