Wallet Creation #

1. Generate a New Wallet #

• Click “Create New Wallet.”
• Assign a recognizable name (e.g., Cold Storage #1).
• The system generates a BIP-39 Mnemonic Phrase.

2. Backup Recovery Phrase #

• Write down the 12/24-word phrase in exact order.
• Use the provided security card for storage.
• Keep it in a secure physical location.
• 🚫 Never photograph or digitize this phrase.

3. Verify Recovery Phrase #

• Re-enter the recovery words in order to confirm.
• The system will validate correctness.
• If incorrect, you must restart verification.

Receiving Cryptocurrency #

1. Select Network #

• Choose from over 15 supported blockchains.
• Each network generates its own address.

2. Generate Address #

• Click “Receive.”
• A QR Code and text address will be displayed.
• Addresses are deterministic — they remain the same each time.

3. Supported Networks #

• EVM: Ethereum, BSC, Polygon, Avalanche, Fantom, Arbitrum, Optimism,…*
• Native: Bitcoin, Solana, XRP, Cardano, TRON, …*
• Tokens: All ERC-20, BEP-20, and custom tokens.

Sending Cryptocurrency (Offline Signing) #

1. Prepare Transaction #

• Enter the recipient’s address.
• Specify the amount to send.
• Review the network fees.

2. Visual Verification #

• System generates a unique visual hash (5×5 color grid + emoji pattern).
• Prevents clipboard hijacking or address tampering.

3. Sign Transaction #

• Transaction is signed offline.
• A QR Code + hexadecimal string are generated.
• Copy the signed transaction to an online device.

4. Broadcast (Online Device) #

• Use any compatible wallet/service.
• Paste the signed transaction.
• Confirm broadcast to the network.

⚠️ Pro Tip:

Consult the Multi-Chain Section in this manual for a complete list of supported networks and protocols.

Custom Token Addition #

1. Add Token #

• Navigate to the target network.
• Click “Add Custom Token.”
• Enter the contract address.

2. Verify Token #

• System fetches token metadata automatically.
• Confirm name, symbol, and decimals.
• Add the token to your wallet.

Import / Export #

XColdPro allows users to import existing wallets (e.g., MetaMask, Exodus, or other software wallets) or export XColdPro-generated wallets for compatibility with external applications.

This flexibility provides convenience but also carries serious security implications that must be understood before proceeding.

What This Means for Users #

Import FROM these wallets: #

• • MetaMask (ETH + all EVM chains)
• • Trezor (ALL networks above)
• • Ledger (ALL networks above)
• • Trust Wallet (ALL networks above)
• • Phantom (Solana)
• • Exodus (Multi-chain)

Export TO these wallets: #

• • Same list – any wallet supporting BIP39/BIP44

Importing External Wallets #

When importing a wallet from another application into XColdPro:

• You are not “moving” the wallet. Importing creates an additional access point, not a migration.
• The wallet remains active on the original application (e.g., MetaMask) unless explicitly deleted.
• As long as the wallet exists in another application, it remains exposed to that application’s vulnerabilities.

⚠️ Important Warning:

If the intent is to place assets into true cold storage, simply importing is not sufficient.

• After confirming successful import and access within XColdPro, the wallet must be deleted from the original application.
• Failing to do so means your wallet continues to exist in a “hot” environment, accessible via the internet, defeating the purpose of cold storage.

Exporting XColdPro Wallets #

Wallets generated within XColdPro are natively Air-Gapped and have never touched the internet.

• Exporting these wallets into a hot environment (e.g., MetaMask or web wallets) introduces risk by exposing private keys/seed phrases to online systems.
• Once exposed, the wallet can no longer be considered 100% cold storage.

Best Practice:

Only export wallets when absolutely necessary for specific network access or decentralized applications. Always consider the trade-off between convenience and long-term security.

⚠️ Critical Security Warning

Importing a wallet does not move it to cold storage.

It only creates an additional access point.

• For true cold storage, the wallet must be deleted from all online applications after importing into XColdPro.
• If you import your XColdPro-generated Seed Phrase into a Hot Wallet, you are permanently exposing it to online risks.
• Seed Phrase = ultimate key. Whoever has it, has your assets.

Remember: Cold storage is only achieved when your wallet exists exclusively inside XColdPro and remains disconnected from internet-based applications.
