Digital Paper Wallet

Overview

Digital Paper Wallet (DPW) is an impregnable fortress for your cryptocurrency keys, empowering Sovereign and HighRisk tier users to generate, encrypt, and store private keys with cold storage-like security, exporting them as BIP-39 mnemonic seed phrases via the coercion-resistant Key Extraction Protocol (KEX). Designed exclusively for secure key management, DPW does not transact or hold keys, enabling seamless transfer to transaction wallets like Ledger or MetaMask for spending. Available only in Sovereign and HighRisk tiers, DPW ensures your Bitcoin, Ethereum, Solana, and other crypto assets remain under your sole, unassailable control.

How It Works

  • Offline Key Generation: Sovereign and HighRisk tier users generate private and public key pairs for Bitcoin, Ethereum, Solana, Ripple, Cardano, Dogecoin, and Litecoin offline in their browser, ensuring no third-party access, including UnoLock.
  • Client-Side Encryption: Keys are encrypted on the user’s device with AES-256 GCM, stored securely in the vault, and backed up to AWS S3 with pre-signed URLs, remaining unreadable without the decryption key.
  • BIP-39 Mnemonic Export via KEX: Keys are exported as 24-word BIP-39 mnemonic seed phrases using the Key Extraction Protocol (KEX), splitting phrases across two offline devices with optional multi-device authentication and self-destructing sessions for secure transfer to transaction wallets.
  • Cold Storage-Like Security: Encrypted keys are stored in a vault-like environment, mirroring cold storage principles, ensuring protection from online threats without transaction capabilities.

Security Implications

  • Zero-Knowledge Sovereignty: Client-side key generation and encryption ensure only you access your private keys, with UnoLock maintaining a zero-knowledge model, eliminating custodial risks.
  • Coercion Resistance: KEX’s split-device mnemonic retrieval, paired with DuressDecoy (Sovereign) and LifeSafe (HighRisk), protects keys against physical or legal coercion, ensuring attacker deception.
  • Cold Storage Resilience: Offline key management and encrypted storage shield keys from online threats like phishing or malware, providing cold storage-like security with digital flexibility.

Use Cases

  • Crypto Investors: Sovereign and HighRisk tier users generate Bitcoin or Ethereum keys offline, exporting mnemonics via KEX to Ledger or MetaMask for secure trading or long-term storage.
  • High-Security Asset Management: HighRisk tier users export Solana keys to Phantom Wallet via KEX, protected by LifeSafe against coercion in high-risk scenarios.
  • Enterprise Crypto Protection: Sovereign tier businesses generate and store corporate crypto keys, using KEX to securely integrate with hardware wallets, ensuring robust security for financial operations.

Why It Matters

Digital Paper Wallet redefines cryptocurrency security by offering Sovereign and HighRisk tier users a cold storage-like vault for key management, with secure KEX export to transaction wallets, ensuring self-sovereign control. In a world of cyber threats and physical risks, DPW’s zero-knowledge design safeguards your digital wealth with unmatched resilience.

FAQs

Can UnoLock access my DPW private keys?

No, DPW’s zero-knowledge model ensures keys are generated and encrypted client-side, inaccessible to UnoLock or any third party.

How does KEX secure mnemonic export?

KEX splits BIP-39 mnemonics across two offline devices with optional multi-device authentication and self-destructing sessions, preventing exposure to coercion, keyloggers, or malware.

Can DPW be used for cryptocurrency transactions?

No, DPW is designed for secure key generation and storage, not transactions; keys are exported via KEX to transaction wallets like Ledger or MetaMask for spending.

Compliance & Privacy Regulations

  • GDPR & HIPAA Compliance: DPW supports GDPR and HIPAA by encrypting keys client-side, ensuring user privacy and control during storage and export in Sovereign and HighRisk tiers.

Integration with Other Features

  • Local File Encryption: Complements DPW by encrypting keys client-side with AES-256 GCM, ensuring robust protection during storage and backup.
  • Post-Quantum Encryption Security: Enhances DPW with quantum-resistant AES-256 GCM encryption, safeguarding keys against future quantum threats.
