1. **Use Hardware Wallets**: Store most holdings offline (e.g., Ledger, Trezor) to avoid exchange hacks.

2. **Enable 2FA**: Protect accounts with app-based 2FA (Google Authenticator), not SMS.

3. **Beware Phishing**: Verify URLs, avoid clicking unsolicited links, and never share seed phrases.

4. **Update Software**: Keep wallets/devices patched to fix vulnerabilities.

5. **Secure Seed Phrases**: Write them on metal/paper, never digitally, and store in multiple safe locations.

6. **Limit Exchange Exposure**: Keep only trading funds on exchanges; withdraw to self-custody wallets.

7. **Avoid Public Wi-Fi**: Use VPNs for transactions.

8. **Audit Permissions**: Revoke unused dApp/contract approvals (e.g., via Revoke.cash).

9. **Diversify Storage**: Split assets across wallets to minimize single-point failures.

10. **Stay Informed**: Follow security updates and scams.

*Security is ongoing—vigilance and proactive habits are non-negotiable.*
