Cold wallets have become essential for crypto security, especially after high-profile exchange collapses like FTX. But what exactly makes them safer than alternatives? Let's break down the fundamentals.
Cold Wallet vs. Hot Wallet: Key Security Differences
Hot Wallets (Like MetaMask)
- Internet-connected: Prone to remote hacking attempts
- Convenience-focused: Designed for frequent transactions
- Higher risk: Single point of failure if device is compromised
Cold Wallets
- Air-gapped storage: Private keys never touch the internet
- Transaction signing: Requires physical confirmation
- Tamper-proof designs: Many include anti-tampering mechanisms
