Staying safe in Web3

As an NFT collector, securing your valuable digital assets is critical. Let's explore best practices for protecting your NFTs, focusing on wallet types, avoiding scams, and staying vigilant.

As an NFT collector, securing your valuable digital assets is critical. In this post, we will explain the best practices for protecting your NFTs, focusing on wallet types, avoiding scams, and staying vigilant.

Wallet Types: Choosing the Right Armor

Understanding wallet types is key to NFT security, as each type offers unique advantages and trade-offs.

Here are three wallet types:

  • Cold Wallets
  • Hot Wallets
  • Warm Wallets

Cold Wallets: The Ultimate NFT Safe

Imagine a cold wallet as your digital safe deposit box, the ultimate choice for securing your NFTs. What makes it so secure is its offline nature – it's like keeping your valuables in a physical safe locked away in your home.

Offline, Unreachable, and Secure:

Unlike hot wallets, which are connected to the internet, cold wallets remain completely offline. This isolation means that your private keys and NFT assets are safe from the prying eyes and cyberattacks of online hackers. Think of it as a digital moat around your fortress.

Perfect for the Long Haul:

Cold wallets are ideal for those who plan to hold their NFTs for the long term or have a substantial collection. Just like you might store precious heirlooms in a bank's safe deposit box for generations, cold wallets ensure your NFT treasures remain intact, regardless of how much time passes.

Examples of Cold Wallets: Ledger, Trezor

Devices like Ledger and Trezor are trusted names in the world of cold wallets. They take your private keys and store them securely offline, making them almost immune to online threats.

The Seed Phrase: Your Safety Net

One crucial aspect of using a cold wallet is your seed phrase. Think of it as your spare key. If you ever lose your cold wallet device or it gets damaged, this seed phrase is your lifeline to recover your NFTs. Protect it as if it were the only key to your digital safe.

Hot Wallets: Your Accessible NFT Companion

Hot wallets are the more accessible, user-friendly side of the NFT security spectrum. These wallets are designed for frequent transactions and easy access to your NFT assets. While they offer convenience, it's important to understand their characteristics and limitations.

Online and Ready:

Unlike cold wallets, which remain offline, hot wallets are connected to the internet. This makes them readily available for managing your NFTs, checking balances, and participating in trading platforms.

Convenience Meets Vulnerability:

The trade-off for this convenience is an increased vulnerability to online threats. Since hot wallets are connected to the internet, they are exposed to potential hacking attempts and phishing attacks. Think of it as keeping your valuable items in an easily accessible drawer versus locking them in a secure vault.

Best for Day-to-Day Use:

Hot wallets are ideal for everyday NFT transactions. If you frequently buy, sell, or trade NFTs and need quick access to your assets, a hot wallet is the way to go. It's like having your wallet in your pocket for everyday expenses.

Examples of Hot Wallets: MetaMask, Rainbow

Popular hot wallets like MetaMask and Rainbow are trusted choices for managing your NFTs. They offer user-friendly interfaces and seamless integration with NFT marketplaces and decentralized applications, making them convenient for active NFT enthusiasts.

Protecting Your Hot Wallet:

To make the most of a hot wallet while mitigating security risks, consider these precautions:

  • Strong Passwords: Use a robust, unique password for your hot wallet to prevent unauthorized access.
  • Two-Factor Authentication (2FA): Enable 2FA whenever possible to add an extra layer of security to your wallet.
  • Be Wary of Phishing: Always verify website URLs and be cautious of emails or messages asking for your wallet information.
  • Limited Funds: Keep only the amount you need for frequent transactions in your hot wallet, and store the rest in a cold wallet for added safety.

Warm Wallets: Balancing Security and Accessibility

Warm wallets strike a balance between the security of cold wallets and the accessibility of hot wallets. They are designed for those who want to maintain a higher level of security while still having relatively convenient access to their NFT assets. Here's what you need to know about warm wallets:

Hybrid Approach:

Warm wallets adopt a hybrid approach to NFT storage. They combine some elements of both cold and hot wallets to achieve a balance. Specifically, the private keys in warm wallets are stored offline, much like in a cold wallet. However, they can be accessed through secure software when needed, similar to how you would access a hot wallet.

Security without Full Isolation:

Unlike cold wallets, warm wallets do not remain entirely disconnected from the internet. This means they are not as impervious to online threats as cold wallets. However, since the private keys are stored offline, they provide a higher level of security compared to traditional hot wallets.

Ideal for Moderate Investments and Transactions:

Warm wallets are well-suited for individuals who want to strike a balance between security and accessibility. If you hold a moderate amount of NFT assets and engage in regular transactions or interactions with the NFT ecosystem, a warm wallet can offer the security you need without the inconvenience of fully offline storage.

Example of a Warm Wallet Setup: Connect Ledger to MetaMask

A common way to create a warm wallet setup is by connecting a hardware wallet like Ledger to a software wallet like MetaMask. This configuration allows you to enjoy the security benefits of a hardware wallet (offline private key storage) while still being able to interact with NFT marketplaces and decentralized applications through MetaMask's user-friendly interface.

Key Considerations:

When using a warm wallet, it's essential to keep a few things in mind:

  • Website Trustworthiness: Ensure that the websites and platforms you use to access your warm wallet are legitimate and secure. Avoid suspicious or unverified websites.
  • Secure Device: The device you use to access your warm wallet should be secure, regularly updated, and free from malware or viruses.
  • Regular Checkups: Periodically review the security of your warm wallet setup and ensure that your private keys remain safe.

Beware of Random Discord Invites


Participating in NFT communities and discussions can be exciting, but it's important to stay cautious when it comes to random Discord server invites. Discord is a popular platform for NFT enthusiasts to connect, but it's also a potential hunting ground for scammers. Here's what you need to know:

The Discord Connection:

Discord is like a digital clubhouse where people gather to chat, share information, and discuss NFTs. It's a valuable resource for connecting with like-minded individuals, but not all invitations to Discord servers are genuine.

The Scam Alert:

Scammers often use the allure of exclusive Discord communities to trick people into granting them access to their wallets. They might send you a random invite, claiming it's for a special NFT group or community, and ask you to sign a message to prove your identity. This can be a ploy to gain control of your wallet.

Stay Safe:

To protect yourself from such scams, follow these essential steps:

  • Verify Server Legitimacy: Before accepting any Discord invite, research the server. Check for official announcements or social media references to confirm its legitimacy.
  • Admin Verification: Ensure that the server has trusted administrators. Genuine NFT communities typically have reputable moderators who can vouch for the server's authenticity.
  • Message Signing Caution: Be extremely cautious when asked to sign messages within Discord. This should only be done in trusted, verified, and well-known NFT communities.

Example: RTFKT Alpha Group Scam

An example of a Discord scam is the RTFKT Alpha Group scam. Scammers created a fake RTFKT Alpha Group Discord server and invited unsuspecting users, convincing them to sign messages. This led to compromised wallets and asset loss.

Be Cautious of Closed Alpha P2E Games


Participating in closed alpha play-to-earn (P2E) games can be exciting, but it's important to approach them with caution to safeguard your NFT assets. Here's what you need to know:

What Are Closed Alpha P2E Games?

Closed alpha P2E games are early versions of play-to-earn games that are typically only available to a select group of testers. These games often involve earning cryptocurrency or NFTs by playing, making them appealing to gamers and collectors.

The Risks Involved:

While closed alpha P2E games can be legitimate and enjoyable, there are risks to be aware of:

  • Scams: Some fraudsters may create fake closed alpha games to trick players into investing time or money. They might promise valuable NFT rewards that never materialize, leading to disappointment and potential loss.
  • Malware: Malicious actors can use fake P2E games as a way to distribute malware. Downloading and running a fake game could compromise your computer's security.

How to Protect Yourself:

Here are some steps you can take to protect yourself when considering closed alpha P2E games:

  • Research: Before participating in any closed alpha P2E game, do thorough research. Look for information about the game's developers, reviews, and community feedback. Legitimate games often have active communities and transparent development teams.
  • Verify Authenticity: Check the official website or social media channels of the game to verify its authenticity. Avoid downloading the game from unofficial sources.
  • Use Security Software: Ensure that your computer has reliable antivirus and anti-malware software installed. Scan any files or downloads related to the game for potential threats.
  • Beware of Requests for Personal Information: Be cautious if the game requests sensitive personal information or access to your wallet. Legitimate games should not ask for excessive personal data or access beyond what's necessary for gameplay.
  • Backup Your NFT Wallet: If you plan to link your NFT wallet to the game, ensure you don't have anything valueable for hackers to take.

Verify What You're Signing


When dealing with NFTs, it's essential to understand what you're signing before you hit that confirm button. This simple yet critical practice can help keep your digital assets safe from unintended actions and potential scams. Here's how to do it:

What Does "Signing" Mean?

In the world of NFTs, "signing" refers to the act of confirming and approving a transaction. Whether you're buying, selling, or transferring NFTs, you'll often be asked to "sign" or approve these actions.

Why Verification Matters:

  • Preventing Mistakes: By verifying what you're signing, you can avoid accidental transactions. NFT transfers are irreversible, so it's crucial to double-check the details before proceeding.
  • Scam Protection: Scammers sometimes try to trick you into signing transactions that transfer your NFTs to their wallets. By verifying, you can spot and avoid these malicious attempts.

How to Verify:

  • Review Transaction Details: Take a close look at the transaction details presented to you. Check the NFT's name, the recipient's address, the quantity, and any associated fees.
  • Understand the Implications: Make sure you understand the consequences of the transaction you're about to sign. For example, if you're selling an NFT, confirm that you're comfortable with the sale terms and the final price.
  • Use Trustworthy Platforms: Ensure you're using a reputable NFT marketplace or wallet that you trust. Be cautious of unfamiliar or unverified platforms.
  • Seek Clarification: If anything seems unclear or suspicious, don't hesitate to seek clarification or advice from trusted sources or communities in the NFT space.
  • Educate Yourself: Take the time to learn about different types of NFT transactions, such as transfers, auctions, and bids. Knowing the differences will help you make informed decisions.
  • Start Small: If you're new to NFTs, consider starting with small transactions to get a feel for the process and build confidence in verifying transactions.

Double-Check Website URLs


One of the essential steps in safeguarding your NFT assets is to double-check website URLs whenever you engage in NFT-related activities. This simple practice can help you avoid falling victim to phishing scams and fraudulent websites. Here's what you need to know:

Risk of Phishing:

Phishing is a common online scam where malicious actors create fake websites that mimic legitimate ones. These counterfeit websites often have URLs that look very similar to the real thing, with slight misspellings or variations. Their goal is to trick you into entering your login credentials or financial information, which they can then steal.

How to Double-Check Website URLs:

  • Read Carefully: Before clicking on any links or entering sensitive information, take a moment to carefully read the URL in your browser's address bar. Pay close attention to spelling, punctuation, and any unusual characters.
  • Look for HTTPS: Legitimate websites that handle sensitive information, like NFT marketplaces or wallet services, use HTTPS encryption. Check for the padlock icon in your browser's address bar and the "https://" prefix in the URL. This indicates a secure connection.
  • Bookmark Trusted Sites: To reduce the risk of accidentally visiting a phishing site, consider bookmarking the official websites of the NFT platforms you use. Then, access these sites through your bookmarks rather than by typing the URL manually.
  • Use Search Engines Wisely: When searching for NFT-related information or platforms, be cautious of search engine results. Phishing sites can sometimes appear in search listings, so double-check the URL before clicking.
  • Verify Social Media Links: Be wary of clicking on links to NFT platforms shared on social media or in messages. Always verify the URL's legitimacy before proceeding.

Why It Matters for NFTs:

NFT transactions often involve valuable digital assets and cryptocurrency. If you inadvertently access a phishing site and provide your wallet credentials or make transactions there, you risk losing your NFTs and funds.


As an NFT collector, securing your digital assets is non-negotiable. We've covered crucial best practices to help you protect your NFTs effectively.

Understanding wallet types is key. Cold wallets offer maximum security but are best for long-term holdings. Hot wallets are convenient for everyday transactions but come with increased risk. Warm wallets balance security and accessibility.

We've also stressed the importance of staying vigilant. Scammers use various tactics, so verify before you trust. Be cautious of Discord invites and skeptical of closed alpha P2E games. Always double-check transactions, website URLs, and consider using protective apps like Wallet Guard.

In the NFT world, your knowledge is your best defense. By following these practices and staying informed, you'll keep your NFT investments safe and secure.

Trust no one offering free fortunes, and remember: your assets, your responsibility.
