So what should you do?
Step 1: Check If Your Email & Passwords Have Been Leaked
- Visit Have I Been Pwned to check if your credentials are compromised.
- If any accounts are breached, change passwords immediately and use a password manager.
Step 2: Enable Two-Factor Authentication (2FA) Everywhere
- US residents can use tools like Efani to prevent SIM swaps and targeted attacks on your mobile communications.
- If not, use an authenticator app (like Google Authenticator) instead of SMS for added security.
Step 3: Use a Secure Browser for Crypto Activities
- Avoid Chrome—it’s commonly targeted by malware. Instead, use Brave for built-in privacy and security.
Step 4: Bookmark Official Sites
- Phishing sites look identical to real ones. Avoid clicking links from search engines—bookmark the real site instead.
Step 5: Double-Check Every Character When Transferring Crypto
- Scammers use lookalike addresses! Always copy-paste & double-check before sending large amounts.
- Send a small test transaction first to confirm the destination address.
Step 6: Revoke Risky Token Approvals
- DeFi dApps request “infinite approval”, meaning they can drain all your tokens if hacked.
- Use Etherscan Token Approval Checker to remove permissions you no longer need.
Step 7: Be Extra Cautious With Bridges
- Cross-chain bridges are high-value targets for hackers. Use only audited & reputable ones.
- Avoid clicking on random bridge links from Discord or X—always go directly to the official website.
- Before using any dApp or DeFi protocol, check for independent security audits from firms like Hacken to reduce the risk of interacting with vulnerable or malicious contracts.
Step 8: Use Separate Wallets for Trading & Long-Term Holdings
- Hot wallets (MetaMask, Rabby, Trust Wallet) are convenient but not secure for large holdings.
- Create a dedicated wallet for trading and DeFi interactions. Keep long-term holdings in a separate, secure, hardware wallet.
Step 9: Upgrade to a Hardware Wallet
- Hardware wallets store your private keys offline, keeping them safe from hacks.
- The majority of your portfolio should be in a hardware wallet, and only keep a small amount in your hot wallet for active trading.
Step 10: Store Your Seed Phrase Properly
- NEVER store it on your phone, email, or cloud storage!
- Use a steel backup for fire, water, and rust-proof storage
- Never share your seed phrase. A reputable company will never ask for your seed phrase. If someone does, they’re almost certainly impersonating a trusted service or brand.
