Crypto Wallet Security: 7 Rules to Protect Your Assets
Jakarta, September 11, 2026 — Millions of dollars in crypto are lost every year due to poor wallet security. Most losses are preventable. Here are seven rules every crypto holder should follow.
1. Never Share Your Seed Phrase
Your seed phrase is the master key to your wallet. No legitimate service will ever ask for it. Anyone who does is a scammer.
2. Use a Hardware Wallet
For holdings above $1,000, a hardware wallet (Ledger, Trezor) keeps your keys offline and safe from malware.
3. Separate Hot and Cold Wallets
Use a hot wallet (MetaMask, Trust Wallet) for daily transactions and a cold wallet for long-term storage.
4. Verify Every URL
Phishing sites mimic popular exchanges and wallets. Always type the URL manually or use a bookmark.
5. Revoke Unused Permissions
DeFi protocols often ask for token approvals. Use tools like Revoke.cash to revoke permissions you no longer need.
6. Enable 2FA
Use an authenticator app, not SMS. SIM-swap attacks are common.
7. Test with Small Amounts
Before sending a large amount, send a small test transaction first.
Conclusion
Security is a habit, not a one-time action. Follow these rules consistently and you will avoid the most common mistakes.
