- Private keys never interact with internet-connected devices
- Uses air-gapped communication methods like QR codes for transactions
Multiple Implementation Methods
- Paper Wallets: Printed or handwritten private keys
- Brain Wallets: Memorized passphrases (requires exceptional recall)
- Hardware Devices: Dedicated cryptographic signing tools
Transaction Security Protocols
- Offline transaction signing capability
- Only broadcasts signed transactions to networked devices
- Tamper-proof hardware construction in advanced models
Cold Wallet Implementation Standards
