Unicity WEB GUI Wallet v0.4.9

Interface Overview

• Main Page Tabs:
  • Wallet Tab: Main wallet operations (Create, Load, Save, Reset, Send, Broadcast)
  • Cold Wallet Tools Tab: UTXO management for offline transactions (Export/Import UTXOs)
• Help Tabs: This help window has two tabs - General Usage (this tab) and Cold Wallet (detailed cold wallet instructions)

Getting Started

• Create New Wallet: Click the "Create" button to generate a new wallet with a secure private key
• Load Existing Wallet: Click the "Load" button to import from:
  • Text Files (.txt): Import wallets from WIF private keys or previously saved BIP32 keys
  • BIP32 Wallet Database (.dat): Import BIP32 hierarchical deterministic wallets from wallet.dat files
  • Encrypted Backup: Restore from password-protected wallet backups (click "Decrypt" button after selecting file)
• Wallet Scanning (BIP32):
  • When opening a BIP32 wallet file, the wallet automatically scans for addresses with balances
  • The scanner will check up to 100 addresses (configurable) for funds
  • Found addresses are displayed with their balances and derivation paths
  • Select any discovered wallet to use for transactions
  • After initial scan, a "Rescan Wallets" button appears to force a fresh scan and clear cache
• Network Connection: The wallet automatically connects to the Unicity network when online. You can also manually connect/disconnect using the endpoint controls

Importing Wallets

• Standard Backup Import: Use the "Load" button to import wallet files. If the backup is encrypted, you'll need to enter the password.
• BIP32 wallet.dat Import (EXPERIMENTAL):
  ⚠️ Important Notes:

  • Only unencrypted wallet.dat files are currently supported
  • No backup copy of wallet.dat is needed - the file is only read, not modified
  • Verify imported addresses: We cannot guarantee correct address restoration. Always compare with alpha-qt or alpha-cli to ensure the right addresses were loaded
  • The scanner checks 100 regular addresses and 100 change addresses by default
  • You can select any non-empty address found during the scan
  • To decrypt wallet.dat: use alpha-cli walletpassphrase "yourpassword" 600 then copy the wallet.dat

Exporting from Alpha Core (alpha-cli/alpha-qt)

• Method 1: Direct wallet.dat Copy (Recommended for BIP32 wallets):
  1. Stop alpha-qt or alpha daemon: alpha-cli stop
  2. Locate your wallet.dat file (usually in ~/.alpha/ or datadir)
  3. If wallet is encrypted, temporarily decrypt it:
     • Start alpha daemon/qt again
     • Run: alpha-cli walletpassphrase "yourpassword" 600
     • Stop the daemon and copy wallet.dat while it's decrypted
  4. Copy the wallet.dat file to a safe location
  5. Use the "Load" button in this wallet to import the wallet.dat file
• Method 2: Export with dumpwallet (Alternative):
  1. If wallet is encrypted, unlock it: alpha-cli walletpassphrase "yourpassword" 600
  2. Export wallet keys: alpha-cli dumpwallet "wallet_export.txt"
  3. The exported file contains all private keys in WIF format
  4. You can import individual WIF keys using the "Load" button
  5. Lock wallet after export: alpha-cli walletlock
• Method 3: Backup wallet (For safekeeping):
  1. Create a backup: alpha-cli backupwallet "wallet_backup.dat"
  2. This creates a copy of your wallet.dat that can be imported the same way

Security

• Save Your Wallet: Click the "Save" button to export your wallet with optional password protection. Write down the password - there's no recovery if forgotten!
• Backup Regularly: Use the "Save" button to create wallet backups. Store backups in multiple secure locations
• Offline Mode: For maximum security, download this page and use it on an offline computer

Complete Cold Wallet Transaction Guide

Initial Setup

1. Prepare Offline Computer:
   • Use a computer that will NEVER connect to internet
   • Download wallet HTML file on online computer
   • Transfer HTML file via USB to offline computer
   • Open wallet, click "Create" to generate new wallet
   • Click "Save" to backup wallet (with password protection)
   • Write down the wallet address (alpha1...)
2. Setup Online Computer:
   • Open wallet in browser
   • DO NOT create or load any wallet
   • Enter your cold wallet address in "Watch:" field
   • This enables watch-only mode for monitoring

Understanding Watch-Only Mode

How to Enable Watch-Only Mode:

1. Clear any loaded wallet: If you see wallet buttons, click "Reset" first
2. Locate Watch field: The "Watch:" input appears in wallet section when no wallet is loaded
3. Enter address: Type or paste your cold wallet's address (alpha1...)
4. Automatic loading: Balance, UTXOs, and history load immediately
5. Ready for transactions: You can now create unsigned transactions

PATH 1: Transaction Template Method (Recommended)

Create transaction template online → Sign offline → Broadcast online

PATH 2: UTXO Export Method (Alternative)

Export UTXOs online → Create & sign offline → Broadcast online

Important Notes & Tips

Troubleshooting

• Watch field not visible? Click "Reset" to clear any loaded wallet first
• UTXOs not showing? Ensure you're connected (green connection status)
• Can't import transaction? Use "Load" button, not "Broadcast" for unsigned files
• Broadcast fails? Check connection status and transaction queue for errors
• Wrong balance? Click "Rescan Wallets" if using BIP32 wallet

Security Best Practices

• Air Gap: Offline computer must NEVER connect to internet, even temporarily
• USB Hygiene:
  • Use dedicated USB for wallet operations only
  • Format USB between uses if possible
  • Never plug wallet USB into untrusted computers
• Verification: Always verify on offline computer:
  • Recipient address (every character)
  • Amount being sent
  • Fee is reasonable (usually 0.0001-0.001 ALPHA)
• Backups: Keep multiple encrypted backups of wallet in different physical locations
• Practice: Test entire process with tiny amounts first (0.001 ALPHA)
