When exploring cryptocurrency wallets like OKX's Web3 Wallet (formerly MateX), many users wonder about security classifications - particularly whether it qualifies as a cold wallet. Let's clarify this fundamental distinction in crypto storage solutions.
Key Differences Between Hot and Cold Wallets
Hot Wallet Characteristics
- Internet-connected: Continuously online for quick transactions
- Convenience-focused: Ideal for frequent trading and DeFi interactions
- Examples: Exchange wallets, mobile wallets like MetaX/Web3 Wallet
Cold Wallet Features
- Offline storage: No internet connection, significantly reducing hack risks
- Security-first: Best for long-term holdings (e.g., hardware wallets, paper wallets)
- Transaction process: Requires manual signing via offline devices
