Operational Security, or OpSec for short, refers to the rigorous process of safeguarding sensitive information to prevent it from falling into the wrong hands. With Bitcoin and cryptocurrencies, OpSec takes on a crucial role in securing digital assets and preserving the confidentiality of transactions. 


The digital landscape is fraught with potential vulnerabilities and threats, not just in crypto, making proactive measures essential. By implementing robust security protocols and staying abreast of the latest security developments, individuals can effectively shield their digital holdings from nefarious actors. At the heart of securing these assets is the choice of wallet, which plays a pivotal role in every transaction and is the primary interface for managing one's digital currency.

Types of Bitcoin Wallets


In crypto, securing your digital coins involves selecting the right kind of "safe" for your digital wealth, and understanding each type of wallet – and what they can offer – is crucial.

Hot wallets

Extension wallets, software wallets, web-based wallets, and mobile wallets fall into the hot wallet category. These are digital wallets that are connected to the internet or a network, allowing users to easily access and manage their assets. 


Wallets like Leather are known as extension wallets. They are wallets that can be installed via a web browser and differ from web-based wallets, which are normally integrated into websites and web applications (Coinbase is a good example). 


Both extension and web-based wallets are also different from software wallets, which tend to be applications that are downloaded to your phone or desktop. Mobile wallets have also grown more popular over the years as wallets opt for mobile apps that can give their users access to their funds on the go. 


It is also important to note that a growing number of hot wallets are also non-custodial or self-custodial like Leather, which gives users complete control over their private keys.  

Cold wallets

Many users opt for hardware wallets, which are compact, physical devices resembling USB drives, designed specifically to store your Bitcoin's private keys offline. They are disconnected from the internet, which shields them from online threats such as hacking or malware. 


When you need to perform a transaction, you connect the hardware wallet to a computer or mobile device, sign the transaction within the device, and then disconnect it, ensuring your keys never leave the device unprotected.

Multi-sig wallets

Multi-signature wallets, often referred to as Multi-sig wallets, require multiple parties to sign off on a transaction before it can be executed. This type of wallet creates an additional layer of security by distributing the responsibility of authorizing transactions among several people. Multi-sig wallets are particularly beneficial for businesses or investment groups where funds need to be accessed by multiple stakeholders, thus preventing any single point of failure.


Each type of wallet serves different needs and comes with its own set of security measures, ensuring that users can choose one that best suits their operational security requirements and personal convenience.

Follow These Rules to Protect Your Crypto


Securing your Bitcoin involves more than just choosing the right wallet; it encompasses a series of prudent practices to enhance security at every step. Always remember the mantra, "Not your keys, not your coins," emphasizing the importance of personal control over your Bitcoin. 


Users can safeguard their assets in a number of ways. These include:

Creating “burner” wallets

A “burner” wallet is separate from a user’s primary wallet, and is often employed to conduct isolated transactions without accessing a user’s main funds. Leather users can generate burner wallets by creating additional accounts within their Leather extension.

Each sub-wallet can be used for a different purpose or to experiment with new dApps, testnets, and more. While Leather accounts are derived from one master seed phrase, users should note that it’s virtually impossible for any additional wallet accounts to be traced back to their main wallet.

Hardware wallet storage

As we mentioned, many users prefer hardware or cold wallets, which do not connect directly to the Internet, for storage. Ledger devices are compatible with the Leather extension and can be connected to the app. 


You’ll still need to ensure that your hardware wallets are updated to benefit from the latest security patches, but be cautious of firmware updates which might be malicious.

Additional best practices

Generally, you should also follow these best practices on an ongoing basis to secure your wallet:

  • Activating two-factor authentication: 2FA adds a layer of security, ideally through a physical device or an app. However, avoid less secure SMS options.

  • Avoid public networks: When accessing your wallet or executing transactions, steer clear of public Wi-Fi, which can be a hotbed for hacker activity. 

  • Password strength: Opt for long, complex passwords and consider a password manager to handle multiple strong passwords efficiently

  • Monitor your wallet activity: Regular monitoring of your wallet’s transaction history can help you spot and respond to unauthorized activity quickly.

  • Vet your dApps: Connect your wallet only to trusted decentralized applications to avoid scams and ensure that you use a separate wallet with limited funds for exploring new and untested applications. 


By integrating these practices into your daily digital routines, you can dramatically enhance the security of your Bitcoin-backed assets.

Protecting Your Bitcoin Wallet


Understanding and implementing operational security is paramount to success within crypto. OpSec is the art of protecting sensitive information—a principle that is critically essential in the realm of digital currency. Effective OpSec involves not only choosing the right security measures but also the right tools, with wallets playing a central role. 


By integrating comprehensive security protocols, users can protect their digital assets from the myriad of threats present in the digital world. Furthermore, adopting practices such as avoiding public Wi-Fi for transactions, using strong and unique passwords, and regularly monitoring transaction histories are crucial steps in fortifying one's wallet defenses. 


Additionally, cautious engagement with decentralized applications and maintaining multiple wallets to spread risk show prudent OpSec in action. Through these measures, anyone venturing into the world of cryptocurrencies can safeguard their investments while maintaining the confidentiality and integrity of their transactions.
