   • Estimated global crypto ownership surpassed 420 million users by 2023.
2. Irreversible Transactions:some text
   • Blockchain transactions are immutable, making error correction or fund recovery nearly impossible.
3. Attractive Targets:some text
   • The high value and pseudonymous nature of crypto assets attract hackers and scammers.

1.2 Common Crypto Security Threats

1. Phishing Attacks:some text
   • Fake websites and emails trick users into revealing private keys or seed phrases.
2. Smart Contract Exploits:some text
   • Vulnerabilities in code enable hackers to drain funds from DeFi platforms.
3. Rug Pulls:some text
   • Malicious developers abandon projects after collecting investor funds.
4. Exchange Hacks:some text
   • Centralized exchanges become targets for large-scale attacks.

   • Use multiple wallets for enhanced security.

‍

3.2 Secure Private Keys and Seed Phrases

1. Avoid Digital Storage:some text
   • Never store sensitive information in digital formats.
2. Use Physical Backups:some text
   • Write down recovery phrases and store them in secure locations.

‍

3.3 Enable Two-Factor Authentication (2FA)

1. Strengthen Account Security:some text
   • Use apps like Google Authenticator or YubiKey instead of SMS-based 2FA.

‍

3.4 Regularly Audit Smart Contracts

1. Code Audits:some text
   • Hire professional auditors to review smart contract code.
2. Continuous Monitoring:some text
   • Use tools like CertiK or Immunefi for ongoing security checks.
