Secure Your Wallets
Use hardware wallets for significant holdings. "Always use self-custodial wallets and use hardware wallets that are air gapped."
Implement Shamir's Secret Sharing for seed phrases. "If you're not good at securing your seedphrase, go for a wallet that supports Shamir's secret sharing, I chose Cypherock for the same reason."
Separate hot and cold wallets. "I keep a cold wallet and hot wallet."
Practice Strong Operational Security
Maintain device hygiene. "I’d add that operational security matters as much as wallets or keys things like device hygiene, separating hot and cold environments, and not reusing emails or passwords tied to crypto accounts."
Never reuse passwords or emails. "Don't reuse passwords."
Use phishing-resistant 2FA like security keys. "Just use a security key wherever you can for your 2FA. This is the only phishing-resistant means to protect an account."
Avoid Scams and Social Engineering
Never share your seed phrase. "Never share your seedphrase with anyone, no matter who they are or what they clai."
Verify all transactions and URLs. "Stop blindly signing transactions/signatures - please verify the transaction data is as expected before signing."
Be wary of unsolicited links and offers. "Never click a link via email, message, web browser search, social media, etc to conduct an action you could otherwise do by going directly to the source."
Additional Security Measures
Keep your crypto holdings private. "Underrated practice: don’t tell anyone that you have crypto."
Consider an offline device for crypto transactions. "Have a laptop you keep powered off and offline that you ONLY use for crypto transactions."
