1. Wallet Security

1.1 Use a Hardware Wallet

Purchase a hardware wallet directly from the manufacturer to avoid tampering (e.g., Ledger, Trezor).

Set up a PIN and enable an optional passphrase for added protection.

Store the wallet in a secure, safe location when not in use.


1.2 Backup Your Recovery Phrase

Write down your recovery phrase on paper and avoid saving it digitally (e.g., in cloud storage).

Store the written phrase in a fireproof and waterproof safe.

Consider using durable backup options like Cryptosteel or Billfodl.


1.3 Avoid Sharing Private Keys

Never share your private keys with anyone, even if they claim to be tech support.

Be cautious of phishing emails or websites asking for private key access.

If your private key is compromised, immediately transfer funds to a new wallet.


2. Account Protection

2.1 Enable 2FA

Use an authenticator app like Google Authenticator or Authy for 2FA instead of SMS.

Enable 2FA on all accounts, including exchanges, wallets, and email.

Regularly update and reconfigure your 2FA settings for extra security.


2.2 Use Strong Passwords

Create long, complex passwords with a mix of uppercase, lowercase, numbers, and symbols.

Use a password manager like LastPass or 1Password to store and generate secure passwords.

Change your passwords periodically, especially for sensitive accounts.


2.3 Review Permissions

Audit all connected applications and platforms linked to your wallet or exchange.

Revoke unnecessary permissions using tools like Revoke.cash.

Check for outdated or suspicious apps in your account settings.


3. Safe Transactions

3.1 Verify Wallet Addresses

Double-check wallet addresses before sending funds to ensure they match.

Use QR codes when possible to avoid manual input errors.

Start with a small test transaction before transferring large amounts.


3.2 Use Trusted Platforms

Research exchanges and trading platforms before use, looking for reviews and security audits.

Stick to well-known, reputable services with strong user bases.

Avoid platforms promising unrealistic returns or bonuses.


3.3 Avoid Suspicious Links

Bookmark official URLs for frequently used services like exchanges or wallets.

Type website addresses directly into the browser instead of clicking links from emails.

Be cautious of unsolicited messages asking for logins or transactions.


4. Smart Contract Security

4.1 Audited Smart Contracts

Check whether a DApp’s smart contracts have been audited by firms like CertiK or Hacken.

Look for public audit reports on the platform’s website or GitHub.

Avoid platforms that cannot provide evidence of a security audit.


4.2 Avoid High-Risk Projects

Research every project thoroughly, including its team, whitepaper, and community activity.

Use tools like RugDoc to assess the risk level of DeFi projects.

Steer clear of projects that lack transparency or over-promise returns.


4.3 Monitor Announcements

Follow official channels like Twitter or Telegram for updates from platforms you use.

Pay attention to security announcements, particularly regarding vulnerabilities.

Take immediate action (e.g., withdrawing funds) if issues arise with a platform.


5. Secure Your Network

5.1 Avoid Public Wi-Fi

Never access exchanges or wallets over public Wi-Fi networks.

Use a VPN like NordVPN or ExpressVPN to encrypt your connection when traveling.

Prefer private, secure networks for all crypto-related activities.


5.2 Use Antivirus Software

Install reputable antivirus software like Bitdefender or Malwarebytes on all devices.

Enable a firewall to block unauthorized access to your computer or network.

Regularly update your antivirus definitions to protect against new threats.


5.3 Update Your Devices

Enable automatic updates for your operating system, browsers, and wallet apps.

Update crypto apps and wallets immediately after new versions are released.

Ensure firmware for hardware wallets is always up to date.
