I. Introduction: Navigating Crypto Wallet Risks
The decentralized nature of cryptocurrency demands rigorous security measures. The DEXX security breach (2024), which resulted in $21 million losses, underscores the critical need for robust private key management.
Key Principle: "Not your keys, not your coins."
Types of Crypto Wallets:

- Cold Wallets (Offline storage, e.g., Ledger)
- Smart Contract Wallets (Programmable, e.g., ERC-4337)
This guide explores wallet security features, selection criteria, and best practices to safeguard your assets.
