Welcome to the exciting world of cryptocurrency! Whether you’re holding Toncoin, Bitcoin, or any other digital asset, you’ve taken a step into the future of finance. But with great power comes great responsibility. In the crypto world, you are your own bank. This means keeping your money safe is up to you.

It might sound intimidating, but it doesn’t have to be.

Think of crypto security like securing your own home. You wouldn’t leave your front door wide open or give your house key to a stranger. The same basic principles apply to your digital wallet. By learning a few simple, best practices, you can protect your assets and explore the crypto space with confidence and peace of mind.

While following security best practices is crucial, it’s also important to be able to recognize specific threats. To learn more, read our detailed guide on how to avoid common scams in the TON ecosystem.

This guide will walk you through the most important steps to secure your crypto wallets and assets. We’ll keep it simple, clear, and focused on what truly matters.

The Golden Rule of Crypto: Your Keys, Your Coins

Before we dive into specific tips, you need to understand the most important concept in crypto security: private keys.

Imagine your crypto wallet is a super-secure digital safe. Your public address (or public key) is like the slot on the front of the safe where people can send you money. You can share this address with anyone without any risk.

Your private key, however, is the secret code that opens the safe. Anyone who has your private key has complete control over your money. They can send it anywhere they want. This is why you must never, ever share your private key with anyone.

Most modern wallets give you a seed phrase (also called a recovery phrase) when you first set it up. This is usually a list of 12 or 24 random words. This seed phrase is just a more user-friendly version of your private key. It’s the master key to your entire wallet. If you lose access to your phone or computer, you can use this phrase to get your wallet back.

If you lose your seed phrase, you lose your money. If someone else gets your seed phrase, they can steal your money. It’s that simple.

Core Security Practices: The Must-Dos

Let’s start with the absolute essentials. If you only do a few things to protect yourself, make them these.

1. Secure Your Seed Phrase Offline

This is the most critical step. How you store your seed phrase determines the security of your entire crypto journey.

Write It Down: Use a pen and paper. Write your 12 or 24 words down clearly and accurately. Double-check the spelling and the order.
Store It Securely: Put this piece of paper in a safe place where it won’t be easily found or damaged. Think of places like a fireproof safe, a safety deposit box, or another secure, secret location. Some people make two copies and store them in different secure locations.
NEVER Store It Digitally: Do not take a screenshot of your seed phrase. Do not save it in a text file on your computer, in your email drafts, in a cloud storage service like Google Drive or Dropbox, or in your phone’s notes app. These digital locations are connected to the internet and are targets for hackers.

2. Use a Strong, Unique Password for Your Wallet

Most wallet apps require a password or a PIN to open them on your device. This is your first line of defense against someone who gets physical access to your phone or computer.

Make it Complex: Use a long password with a mix of uppercase letters, lowercase letters, numbers, and symbols.
Make it Unique: Don’t reuse a password you use for your email, social media, or anything else. If another service gets hacked, criminals won’t be able to use that same password to get into your crypto wallet.
Use Biometrics: If your wallet supports it, enable Face ID or fingerprint scanning. It’s a convenient and secure way to access your app.

3. Enable Two-Factor Authentication (2FA)

Two-Factor Authentication adds a crucial second layer of security. Even if a hacker steals your password, they still won’t be able to get in without the second factor.

What it is: After entering your password, you’ll need to provide a second piece of information—usually a 6-digit code from an app on your phone.
Use an Authenticator App: The most secure method is to use an app like Google Authenticator, Microsoft Authenticator, or Authy. Avoid using SMS (text message) for 2FA if possible, as phone numbers can sometimes be stolen by hackers.
Use it Everywhere: Enable 2FA not just on your wallet (if it supports it), but also on the email account associated with any crypto services you use.

Choosing and Using Wallets Wisely

Not all wallets are created equal. Your security also depends on using the right tool for the job. For instance, if you’re active in The Open Network, choosing a reliable wallet is your first step. You can explore a detailed list of the top 10 TON wallets for 2025
to see specific examples.

1. Understand Hot Wallets vs. Cold Wallets

Hot Wallets: These are wallets that are connected to the internet. They include mobile apps, desktop applications, and browser extensions. They are very convenient for making frequent transactions and interacting with apps. Most of the wallets people use day-to-day are hot wallets.
Cold Wallets (Hardware Wallets): These are small, physical devices (like a USB stick) that store your private keys completely offline. They are the most secure way to store cryptocurrency, especially large amounts. You only connect them to your computer when you need to approve a transaction.

A Simple Strategy: A great approach for most people is to use both. Keep a small amount of crypto in a hot wallet for everyday use, like trading or using apps. Store the majority of your assets—your long-term savings—in a secure cold wallet.

2. Be Careful with Public Wi-Fi

Public Wi-Fi networks (at cafes, airports, hotels) are not secure. Hackers can use these networks to spy on your activity or trick you. Avoid accessing your crypto wallet or making transactions when connected to public Wi-Fi. If you absolutely must, use a reputable VPN (Virtual Private Network) to encrypt your connection.

3. Keep Your Software Updated

Wallet developers are constantly working to improve security and fix potential vulnerabilities. Always make sure your wallet app, your phone’s operating system, and your computer’s operating system are updated to the latest version.

Protecting Yourself from Scams

Technology is only half the battle. The other half is being aware of the tricks and scams that criminals use to try and fool you.

1. Beware of Phishing

Phishing is when a scammer creates a fake website, email, or message that looks like it’s from a legitimate company to trick you into entering your password or seed phrase.

Check URLs Carefully: Always double-check the website address. Scammers often use addresses that look very similar to the real one (e.g., “https://www.google.com/search?q=mywaillet.com” instead of “mywallet.com”).
Be Skeptical of Emails and DMs: Legitimate companies will NEVER ask you for your seed phrase or private key. Never. Be suspicious of any message that creates a sense of urgency, like “Your account will be suspended unless you verify now!”
Don’t Click Suspicious Links: If you get an unexpected email or message with a link, it’s safest to go directly to the official website by typing the address yourself.

2. Your Wallet, Your Digital Identity

As you use your wallet more, its address becomes your identity on the blockchain. For an easier and more secure experience, you might want to give your long, complicated address a simple, human-readable name. This is where blockchain domain services come in. For a network like TON, for instance, a memorable .ton domain can make receiving funds less prone to errors. When considering this, it’s wise to look for an all-in-one platform that simplifies the process of registering and managing your blockchain domain, as this can be a part of securing your overall on-chain identity.

3. Safe Interactions with dApps and Trading

Your wallet is your gateway to a world of decentralized applications (dApps), including trading platforms. When you connect your wallet to a dApp, you are giving it permission to interact with your funds.

Use Reputable dApps: Stick to well-known and audited platforms. Look for community reviews and do your research before connecting your wallet.
Revoke Permissions: After you are finished using a dApp, it’s good practice to revoke its access to your wallet. Tools like Etherscan (for Ethereum) or other blockchain explorers often have features that let you manage these connections.
Seek Simplicity and Security in Trading: The best trading experiences often come from platforms that integrate smoothly and securely with your wallet. Look for user-friendly interfaces that make complex actions feel simple, removing potential for costly mistakes. An innovative trading platform might even operate directly from within a familiar application you already trust, making the entire experience feel as intuitive and easy as Pie.

Final Checklist for Peace of Mind

Feeling a little overwhelmed? Don’t be. Here’s a simple checklist to run through:

Did I write down my seed phrase on paper?
Is my seed phrase stored in a secure, secret, offline location?
Is it completely erased from my computer and phone?
Do I have a strong, unique password for my wallet app?
Is Two-Factor Authentication (2FA) enabled on my important accounts?
Am I using a cold wallet for my long-term savings?
Do I double-check website links and stay skeptical of unsolicited messages?

By following these best practices, you are taking control of your financial future and building a strong foundation of security. Your crypto journey should be exciting and empowering, and with these simple habits, you can ensure it stays that way. Stay vigilant, stay educated, and keep your assets safe!
