Understanding Paper Wallets
Among the various options for storing cryptocurrencies, paper wallets stand out as a secure offline solution. Unlike hardware or software wallets, a paper wallet is simply a physical document containing your public and private keys printed on paper. This method eliminates digital vulnerabilities like hacking or malware but requires careful handling to ensure security.
Why Choose a Paper Wallet?
- Enhanced Security: Offline storage protects against online threats.
- No Hardware Dependency: Doesn’t rely on devices prone to failure or theft.
- Multi-Currency Support: Some generators support 30+ cryptocurrencies, not just Bitcoin.
Step 1: Preparing to Create a Paper Wallet
Safety Precautions
Before generating a paper wallet, follow these critical steps to avoid risks:
- Avoid Online Generators: Never use web-based tools; malware could steal your keys.
- Verify Source Files: Download tools only from trusted repositories like GitHub.
- Work Offline: Disconnect your device from the internet during key generation.
- Use a Clean OS: A Linux live USB ensures no background malware interferes.
- Secure Printing: Print at home and clear the printer’s memory afterward.
- Storage: Laminate the wallet and store it in a fireproof/waterproof safe.
