Decoy Wallets

XColdPro ships with plausible deniability built into the foundation. A Decoy Wallet gives you something credible to open under coercion: what you surrender looks complete and reveals nothing about what else exists.

There is no visual indicator, no hidden menu, and no forensic trace pointing beyond what the attacker is shown. Configuration is covered in the licensed user manual.

Use Case — $5 wrench attack. Someone demands access to your wallet at gunpoint. You open a Decoy Wallet. They see a wallet with $200 in ETH and nothing that suggests anything further exists.

Security Protocols

Protocol 1 — BlackHole (Duress Layer)

An advanced duress-protection layer — a Nyxor-tier capability.

Under forced disclosure, what an attacker obtains does not lead to your assets. Nothing about what you hand over signals that a further layer is in play.

BlackHole is opt-in. With the layer off, your keys stay standards-based and portable — a plain BIP-39 seed that restores anywhere. Enabling it trades that portability for coercion resistance, by design.

  • Opt-in — never a condition of using the product
  • No visible indicator — the wallet behaves normally in daily use
  • Zero forensic trace — nothing on the device points to the layer
  • Documented for licence holders — setup and recovery live in the licensed user manual

Use Case. You keep a backup off-site. Even if that location is compromised, what is recovered there does not reach your holdings.

Protocol 2 — XBurnPro (Time-Locked Escrow)

Create time-locked burner wallets for escrow, proof-of-funds, or permanent destruction.

XBurnPro generates a temporary wallet, funds it from your main wallet, and locks it with a countdown timer. When the timer expires, you choose: claim the funds back, transfer to a recipient, or burn them permanently.

  • Three execution modes — Claim (retrieve), Transfer (send to recipient), or Burn (destroy forever)
  • Supported networks — BTC, ETH, BSC, SOL, XLM, DOGE with confirmed sign and broadcast
  • Timer presets — 1 hour, 1 day, 3 days, 7 days, or custom duration
  • Cryptographic proof — on-chain evidence that funds existed and were locked
  • Burner history — full audit trail of every escrow created

Use Case — Proof of funds for a deal. Lock $50K in BTC into a burner for 72 hours. Show the counterparty the funded address. If the deal closes, claim and transfer. If it falls through, the funds return automatically. If you need to walk away permanently, burn them.

Protocol 3 — Omega Protocol (Emergency Evacuation)

One-tap panic button that liquidates every asset across every network to pre-configured emergency addresses.

When activated, Omega Protocol sweeps all holdings from all 22 networks and all ERC-20 tokens to your emergency addresses. No manual intervention. No per-network setup. One button. Configure it once, and if you ever need to evacuate, it fires across every chain simultaneously.

  • 22 networks + ERC-20 tokens — sweeps everything in one execution
  • Per-network-family emergency addresses — separate destinations for EVM, Bitcoin family, and individual chains
  • Automatic fee estimation — calculates gas and network fees before execution
  • Wipe mode — optionally destroy Omega configuration after execution to eliminate traces
  • Execution status tracking — real-time per-network success/failure reporting

Use Case — Device compromise. You discover malware on your system. One tap on Omega Protocol — all assets across all chains are instantly sent to your cold backup addresses. The attacker gets an empty wallet.

Protocol 4 — Lazarus Protocol (Automated Inheritance)

Five-stage automated inheritance system that transfers your crypto to beneficiaries if you become incapacitated.

Lazarus monitors your activity. If you stop interacting with XColdPro for a configured period, it begins a staged execution chain: detection, notification, claim, verification, and payout. Your crypto does not die with you.

  • 5-stage execution chain — detection, notification, claim, verification, payout
  • Configurable inactivity timeout — set the trigger window (weeks or months)
  • Multiple beneficiaries — split inheritance across multiple recipients
  • Graceful cancellation — prove you are alive and cancel the countdown at any stage
  • Cross-chain execution — works across all 22 supported networks

Use Case — Estate planning. You hold $2M across BTC, ETH, and SOL. You configure Lazarus with a 90-day timeout and your spouse as beneficiary. If something happens to you, after 90 days of inactivity, Lazarus initiates transfer. No lawyers, no probate, no lost keys.

Protocol 5 — Seed Vault (Distributed Recovery)

Shamir Secret Sharing splits your seed into N shares where any M shares can reconstruct it — but M-1 shares reveal absolutely nothing.

Instead of storing one seed phrase in one location (single point of failure), Seed Vault lets you distribute shares across multiple secure locations. Any individual share is mathematically useless. Only the threshold number of shares together can recover your wallet.

  • Configurable M-of-N — 2-of-3, 3-of-5, or any threshold you choose
  • Zero-knowledge shares — individual shares contain zero information about the seed
  • Multi-location distribution — safe deposit box, trusted person, home safe
  • Perfect for estate planning — give shares to family members, attorney, executor
  • No single point of failure — losing one share does not compromise your wallet

Use Case — 3-of-5 split. You generate 5 shares. One goes in your home safe. One to your spouse. One to your attorney. One to a bank vault. One to a trusted friend. Any 3 of them can recover your wallet. No single person or location can compromise it alone.

Protocol 6 — Citadel Protocol (Offline Multi-Party Approval)

Multi-signature authorization that works 100% offline without smart contracts, hot wallets, or blockchain support.

Traditional multisig requires on-chain smart contracts that only work on specific networks. Citadel works on every blockchain, even those with no smart contract support, using air-gapped coordination via QR codes or USB. No internet required at any step.

  • Works on every chain — not limited to EVM or smart-contract-capable networks
  • Configurable M-of-N — require 2-of-3, 3-of-5, or any approval threshold
  • Air-gapped coordination — QR code or USB-based transaction distribution
  • No hot wallet exposure — all signers can remain fully offline
  • More secure than on-chain multisig — no smart contract vulnerabilities

Use Case — Corporate treasury. Your company holds $10M in crypto. No single person can move funds. The CFO creates a transaction, scans a QR code to the CEO's air-gapped device, who approves and passes to the Board member for final signature. Three approvals, zero internet exposure.

Active Protection — Sentinel Guard

Multi-shield malware protection with real-time process monitoring, clipboard hijack detection, and automatic threat termination.

  • Clipboard Guard — re-reads the clipboard after every copy and detects address substitution within a 100 ms window
  • Memory Protector — prevents RAM scraping of private keys and seed phrases
  • Screen Capture Blocker — blocks unauthorized screenshot and screen recording attempts
  • Anti-Debugger — detects and blocks debugger attachment to the wallet process
  • DLL/Dylib Monitor — detects malicious library injection in real-time
  • Rootkit Scanner — deep system scan for kernel-level threats
  • C2 Detection — identifies command-and-control server connections
  • Behavior Analysis — process execution pattern monitoring with auto-terminate
  • Global Threat Intel — signatures from ThreatFox, MalwareBazaar, Feodo Tracker, URLhaus
  • Background monitoring — continuous 45-second scan cycle with zero performance impact

Admin Tools & Tax Compliance

Cost Basis Tracking

XColdPro tracks the cost basis of every transaction across every network. Choose your accounting method and generate reports ready for your tax professional.

  • FIFO — First-In, First-Out (most common for US tax reporting)
  • LIFO — Last-In, First-Out (minimize short-term gains)
  • HIFO — Highest-In, First-Out (maximize cost basis, minimize taxable gains)
  • Realized & unrealized gains/losses — see your complete tax picture before year-end
  • Per-transaction tracking — every buy, sell, transfer, and swap recorded with cost basis

Export & Reporting

  • CSV export — wallet addresses, balances, token holdings, USD values, and transactions
  • Combined or separate — all data in one file or split by type
  • Date range filtering — export transactions for specific tax periods
  • Tax report generator — filter by year, network, and cost basis method (FIFO/LIFO/HIFO)
  • Portfolio summary — total cost basis, current value, unrealized gain/loss with percentage

Address Book

Professional contact management for wallet addresses across all networks. Organize by category, add notes and tags, search instantly.

  • Categories — Personal, Business, Exchange, Family, Other
  • Per-network addresses — store contacts for any supported chain
  • Search & filter — find contacts by name, address, notes, or tags
  • CSV export — export your full address book

Stealth Architecture

Your wallet data does not exist in any findable, readable, or recognizable form. XColdPro's Stealth Storage System scatters encrypted wallet data across platform-native locations using randomized filenames that blend into the operating system's own file structure. No file browser, no search tool, and no forensic scanner can distinguish XColdPro data from legitimate system files.

Even if an attacker locates the files, they are AES-256 encrypted, integrity-validated on every read, and bound to the device hardware. There is nothing to open, nothing to read, and nothing to reverse engineer. The data is designed to be highly resistant to inspection, discovery, and tampering.

Six Protocols. One Vault. Zero Compromise.

XColdPro is not a wallet. It is an AES-256 encrypted cold storage security platform engineered to make compromise computationally infeasible with current practical methods. AES-256-GCM authenticated encryption for the vault, with PBKDF2 key derivation (100,000 iterations; 150,000 with USB Binding). The optional Nyxor BlackHole seed-transformation layer uses AES-256-CTR with PBKDF2 at 500,000 iterations. Decrypted key material released on lock and on exit. Plausible deniability at every layer. Real-time threat annihilation. Automated inheritance. Emergency evacuation. Offline multi-signature. Time-locked escrow. Full tax compliance. 22 native blockchains plus thousands of ERC-20 and SPL tokens.

Brute force is computationally infeasible against PBKDF2 key derivation at 100,000 iterations or more. Stealth-encrypted storage is designed to be highly resistant to forensic discovery. Dual-password deniability removes the social-engineering shortcut. Each layer must be independently defeated — materially increasing the cost and complexity of compromise.
