Security Best Practices for Hot Wallets: - Never store large amounts in hot wallets (keep the majority in cold storage) - Use separate wallets for different purposes (one for DeFi, one for holding) - Regularly revoke token approvals (check via Revoke.cash) - Never enter your seed phrase into any website - Be cautious with browser wallet permissions - Enable all available security features (biometrics, passcode)
Attack Vectors: - Phishing: Fake websites that mimic legitimate dApps - Malicious Approvals: Token approvals that give attackers unlimited spending rights - Clipboard Malware: Replaces copied wallet addresses with the attacker's address - Compromised Browser Extensions: Malicious extensions reading wallet data
Recommended Setup: Use a hot wallet with small amounts for daily DeFi activity, and keep the majority of holdings in a hardware (cold) wallet. Many users pair a hardware wallet with MetaMask for the best combination of security and convenience.
