Protecting Your Crypto Assets: A 2025 Security Checklist

With over $3 billion lost to crypto crime in the first half of 2025 alone, protecting your digital assets has never been more important. This comprehensive checklist will help you stay safe.

Wallet Security

Hardware Wallets

Store significant holdings on hardware wallets
Buy directly from manufacturers (never secondhand)
Keep firmware updated
Store recovery phrases offline in multiple secure locations

Software Wallets

Use reputable, open-source wallets
Enable all available security features
Never store large amounts in hot wallets
Regularly check for and install updates

Seed Phrase Protection

Your seed phrase is the master key to your crypto. Protect it like your life depends on it:

Never store digitally - No photos, no cloud storage, no password managers
Never share with anyone - No legitimate service will ever ask for it
Use metal backup - Paper can burn or get water damaged
Consider splitting - Store parts in different secure locations
Test your backup - Verify you can recover before you need to

Transaction Security

Before sending any transaction:

Verify the address - Use tools like Wisesama to check if an address is associated with scams
Double-check amounts - Especially the number of zeros
Send a test transaction - For large amounts, send a small test first
Verify on the device - If using a hardware wallet, confirm on the device screen

Phishing Prevention

With AI-powered phishing up 1,633% in 2025:

Bookmark official sites - Never click links in emails or messages
Verify URLs carefully - Scammers use similar-looking domains
Be skeptical of urgency - Legitimate services don't pressure you
Use hardware keys - They're phishing-resistant
Enable 2FA everywhere - But avoid SMS-based 2FA when possible

Social Engineering Defense

The most sophisticated attacks target humans, not technology:

No legitimate support will DM you first
No real giveaway requires you to send crypto first
No emergency requires you to act in the next 5 minutes
When in doubt, verify through official channels

Network Security

Use a VPN on public networks
Keep your devices updated
Use a dedicated device for crypto if possible
Be cautious of browser extensions

The Wisesama Way

Tools like Wisesama help you verify:

Addresses - Check if they're associated with known scams
URLs - Verify websites aren't phishing sites
Social profiles - Confirm identities before trusting

Quick Reference Checklist

[ ] Using hardware wallet for main holdings
[ ] Seed phrase stored offline in multiple locations
[ ] 2FA enabled on all exchanges and services
[ ] Bookmarks for all crypto sites (no clicking links)
[ ] Test transaction habit for large transfers
[ ] Regular security updates on all devices
[ ] Address verification before every transaction

Stay safe out there. The crypto space is full of opportunity, but also full of people trying to take advantage. A few minutes of verification can save you from devastating losses.
