Module 3: Wallets and Security

Welcome to Module 3! Previously, you learned what crypto is (Module 1) and how blockchain works (Module 2). Now it’s time to explore wallets—your personal gateway to the crypto world.

Section 1: What Is a Crypto Wallet?

A crypto wallet is like your own digital vault, storing the tools you need to interact with your crypto assets on the blockchain. Instead of physically holding your coins (they always live on the blockchain), the wallet secures your keys, the crucial data that proves your ownership of those coins.

‍

🔑 Private Key vs. Public Key

• Public Key:
  
  • Similar to your bank account number, safe to share for receiving funds.
  • Example Format (Bitcoin): 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
  • Example Format (Ethereum): 0x31aDe13FA91EFAD242Ea3C5BD4db77f9…
• Private Key:
  
  • More like your PIN or master password, whoever holds it can control your crypto.
  • Example Format (Bitcoin WIF): 5HueCGU8rMjxEXxiPuD5BDu6mkq…
  • Example Format (Ethereum Hex): 0xa3d44f614d1ff55dbc41f36bdc23c…

‍

⚠ Warning: If you lose your private key, or it gets stolen, there’s no helpline that can recover it. Security matters more than ever here.

💡 Fun Fact: Many people think “my crypto is in my wallet,” but technically, your assets remain on the blockchain ledger. The wallet only stores your keys, which unlock access to those assets.

‍

Section 2: Hot Wallets vs. Cold Wallets

Not all wallets are created equal. A huge factor is whether they’re connected to the internet.

🔥 Hot Wallets

• Online & Convenient
  
  • Typically come as mobile apps, web wallets, or desktop wallets.
  • Easy access for day-to-day transactions, like using a debit card for small purchases.
• Security Trade-Off
  
  • Always online, so more vulnerable to hacking attempts.
  • Great for frequent trading or quick transfers.

❄ Cold Wallets

• Offline & Ultra-Secure
  
  • Think hardware wallets (e.g., Ledger, Trezor) or paper wallets (literally a piece of paper with your keys printed on it).
  • Since they’re offline, it’s much harder for hackers to access them.
• Less Convenient
  
  • Ideal for long-term storage or “HODLing” large amounts.
  • If you like to check your crypto portfolio five times a day, cold wallets can feel cumbersome.

💡 Pro Tip: Many seasoned crypto users keep a hot wallet for small, frequent transactions and a cold wallet for safely storing the bulk of their holdings.

‍

Section 3: Custodial vs. Non-Custodial Wallets

Another big decision is who controls your private keys.

🛡 Custodial Wallets

• Keys Held by a Third Party
  
  • Exchanges like Wayex typically provide custodial wallets.
  • Recovery is simpler if you forget passwords—just prove your identity, and the exchange can help.
• Trust Factor
  
  • You trust the platform’s security measures. If it’s compromised, your assets could be at risk.
• Ease of Use
  
  • Great for beginners or those who want fewer technical headaches.

🔑 Non-Custodial Wallets

• Your Keys, Your Coins
  
  • You manage your private keys directly—no one can freeze or seize your funds.
• High Responsibility
  
  • If you lose those keys, you’re out of luck—there’s no password reset.
• Examples
  
  • Hardware wallets (Ledger, Trezor), many mobile/desktop wallets (e.g., MetaMask, Trust Wallet).

💬 Crypto Saying: “Not your keys, not your coins.” It’s a friendly reminder that true ownership only comes when you control the private keys.

Section 4: How to Set Up a Secure Wallet on Wayex

🛠 Step 1: Download and Install

• Get the Wayex app from the official App Store/Google Play, or visit my.wayex.com.
• Double-check you’re not on a phishing site. Bookmark the correct URL to avoid mix-ups.

📧 Step 2: Account Creation

• Sign up using a valid email and secure password.
• Complete KYC verification (upload ID documents).

💰 Step 3: Wallet Setup

• Once verified, Wayex auto-generates a wallet for each crypto you want to hold.
• Send funds from another wallet or exchange by using your public receive address.
• Because Wayex is a custodial wallet, you won’t see your private key. Wayex holds it on your behalf with robust security protocols (read more on that below!).

Section 5: Best Practices for Securing Your Assets

Securing your crypto is like fortifying a castle: a strong fortress keeps out invaders, but one unlocked door can spell disaster.

1. Use Strong Passwords 🔐
   
   • Ditch “Password123.” Aim for 12+ characters, mixing letters, numbers, and symbols.
   • Consider a reputable password manager.
2. Enable Two-Factor Authentication (2FA) 📲
   
   • A must for any crypto account. Apps like Google Authenticator or Authy generate time-sensitive codes.
   • This ensures even if someone has your password, they can’t log in without the 2FA code.
3. Store Recovery Phrases & Private Keys Safely 📝
   
   • For non-custodial wallets, keep your seed phrase (12–24 words) offline.
   • Creative Storage:
     
     • Write them on metal sheets (fireproof!).
     • Split your phrase in two parts, each stored in different secure locations.
     • Engrave on a piece of wood or metal—just don’t lose it in that “boating accident!”
   • Avoid saving as screenshots or notes on your phone or computer.
4. The “Boating Accident” Joke 💀
   
   • People often joke about losing all their crypto in a “tragic boating accident.”
   • While humorous, it reminds us that if your keys are truly gone, your crypto is gone too.
5. Regular Software Updates 🔩
   
   • Outdated apps are prime hacker targets. Keep your OS, wallet apps, and antivirus software up to date.
6. Never Share Your Keys 🔑
   
   • Not with a friend, not with “support staff,” not with your cat. If anyone asks for them, it’s a scam.

‍

Real-World Horror Stories

• Hard Drive in the Landfill: One user accidentally threw away a hard drive holding thousands of BTC, now worth millions. He’s tried (and failed) to dig it up from the local tip!
• Lost Passphrase: Another user stored their keys on an encrypted USB stick and forgot the passphrase. Years later, still no luck guessing it.

Section 6: Avoiding Scams and Phishing Attacks

Scammers love crypto’s anonymity and global reach. Stay one step ahead:

1. Verify Links 🔗

• Phishing sites can mimic real websites. Example Only - (like “wayex-verify.com” instead of “my.wayex.com”).
• Always check the URL bar or use a saved bookmark.

2. Beware of Urgent Messages 🚨

• Emails or DMs saying “Your account is compromised, click here to fix it” are huge red flags.
• When in doubt, go directly to the official site or contact support via a known channel.

3. No One Legit Asks for Keys 🛑

• Not Wayex support, not your favourite influencer, not even “the government.”
• If someone requests your seed phrase or private key, they’re a scammer.

4. Stay Informed 📚

• New scams pop up regularly, Ponzi schemes, fake airdrops, etc. Following reputable crypto news sources can keep you alert.

Closing Thoughts‍

Wallets are central to your crypto journey, whether you’re a casual user buying a little bit of BTC or an active trader moving large sums. Balancing convenience (hot wallet, custodial approach) with security (cold wallet, self-custody) is key, and there’s no one-size-fits-all solution. Remember: protect those private keys, think twice before clicking any suspicious link, and if anyone asks for your seed phrase, run the other way!
