1. What Is Mnemonic to BRC-100?

Mnemonic to BRC-100 is a utility tool for deriving BRC-100 compatible wallet addresses from mnemonic seed phrases. It supports multiple wallet types including Centbee, Rock Wallet, and Electrum SV, allowing users to recover addresses and manage coins across different wallet implementations using standardized derivation paths.

Key Features:

  • Multi-Wallet Support - Compatible with Centbee, Rock Wallet, Electrum SV, and common derivation paths

  • Mnemonic Recovery - Derive addresses from 12 or 24-word seed phrases

  • Adjustable Gap/Offset - Find unused addresses with configurable gap limits

  • PIN Support - Optional PIN/passphrase for additional security

  • Address Generation - Generate multiple addresses from a single mnemonic

  • UTXO Management - View and manage unspent transaction outputs

  • Browser-Based - Runs entirely in your browser for privacy

Target Users: Cryptocurrency users recovering wallet access, developers working with HD wallets, anyone needing to derive addresses from mnemonics across different wallet implementations.

2. Before You Begin

Prerequisites

  • Mnemonic Phrase: 12 or 24-word seed phrase from your wallet

  • Web Browser: Modern browser with JavaScript enabled (Chrome, Firefox, Safari, Edge)

  • Wallet Type Knowledge: Know which wallet generated your mnemonic (Centbee, Rock Wallet, etc.)

  • Optional PIN: If your wallet uses a PIN or passphrase

Supported Platforms

  • Web-based: Access via https://mnemonic-brc100.vercel.app/

  • Cross-platform: Works on desktop and mobile browsers

  • No Installation Required: Pure web application

  • Offline Capable: Can be run offline for enhanced security

Security Considerations

  • Never share your mnemonic: This tool processes mnemonics locally in your browser

  • Use offline when possible: Download and run locally for maximum security

  • Clear browser after use: Clear cache and history after using the tool

  • Private environment: Use in a secure, private location

3. Getting Started: Step-by-Step

Step 1: Access the Tool

  1. Navigate to https://mnemonic-brc100.vercel.app/ in your web browser

  2. For maximum security, consider downloading the page for offline use

  3. The main form will appear with input fields

Main mnemonic input form

Step 2: Enter Your Mnemonic

  1. Enter your 12 or 24-word mnemonic phrase in the designated field

  2. Words should be space-separated

  3. Ensure correct spelling - mnemonics are case-sensitive

  4. If your wallet uses a PIN or passphrase, enter it in the optional PIN field

Step 3: Select Wallet Type and Derivation Path

Choose the correct derivation path for your wallet type:

Wallet
Derivation Path
Use When

Centbee

m/44'/0'/0

Recovering Centbee wallet addresses

Rock Wallet

m/0'/0

Recovering Rock Wallet addresses

Electrum SV

m/44'/236'/0'

Recovering Electrum SV wallet addresses

Common

m/44'/0'/0'

Standard BIP44 Bitcoin derivation path

  1. Select your wallet type from the dropdown or radio buttons

  2. The derivation path will be automatically set

  3. Advanced users can manually enter custom derivation paths if needed

Step 4: Configure Gap Limit (Optional)

  1. Set the gap limit or offset for address discovery

  2. Gap limit determines how many unused addresses to check

  3. Default is usually 20; increase if you've generated many addresses

  4. Higher gap limits take longer but find more addresses

Step 5: Generate Addresses

  1. Click "Generate" or "Derive Addresses" button

  2. The tool will derive addresses based on your mnemonic and settings

  3. View the generated addresses in the results section

  4. Each address shows:

    • Address string

    • Derivation index

    • Balance (if connected to blockchain)

    • UTXO information

Step 6: Manage Your Coins

  1. Review generated addresses and their balances

  2. Identify addresses with UTXOs (unspent coins)

  3. Use this information to:

    • Import addresses into wallets

    • Track down missing funds

    • Understand address usage

    • Plan transactions

4. Advanced Features

Custom Derivation Paths

Advanced users can specify custom BIP32/BIP44 derivation paths:

  • Format: m/purpose'/coin_type'/account'/change/address_index

  • Experimentation: Try different paths for recovery scenarios

  • Documentation: Research BIP32, BIP44, and BIP49 standards

Gap Limit Optimization

  • Small Gap (1-10): Quick address generation for recently used wallets

  • Medium Gap (20-50): Standard recovery scenarios

  • Large Gap (100+): Comprehensive search for heavily-used wallets

  • Performance: Higher gaps increase computation time

Security Best Practices

  • Run Locally: Download and run on offline computer for sensitive operations

  • Clear Browser: Delete browsing data after use

  • Verify Results: Always verify addresses on-chain before transactions

  • Test First: Use test mnemonics to understand the tool before real use

Wallet Integration

  • Export Addresses: Copy addresses to import into other wallets

  • Balance Checking: Verify funds before attempting recovery

  • Transaction Planning: Identify which addresses hold your coins

5. Troubleshooting & FAQs

Common Issues

Problem
Cause
Solution

No addresses generated

Incorrect mnemonic or derivation path

Verify mnemonic spelling; try different wallet types

Wrong addresses shown

Wrong derivation path selected

Try all wallet types; check if PIN is required

Balance not appearing

Not connected to blockchain or network issue

Refresh page; check internet connection; verify address on-chain

Tool not loading

Browser compatibility

Use latest Chrome, Firefox, Safari, or Edge

Mnemonic rejected

Invalid word or format

Check spelling; ensure words are BIP39-compatible

Important Tips

  • Refresh after spending: Refresh page after making transactions to update balances

  • Verify on-chain: Always verify addresses and balances on a blockchain explorer

  • Run code locally: Download and run offline for best security practices

  • Document your wallet type: Remember which wallet created your mnemonic

  • Test before trusting: Practice with a small amount first

Security Warnings

  • Never share mnemonics: Anyone with your mnemonic controls your funds

  • Beware of phishing: Only use the official tool URL

  • Use private network: Don't use public WiFi for mnemonic operations

  • Clear history: Remove all traces after use on shared computers
