Bitcoin Silver Web Wallet

A simple, minimal web wallet for Bitcoin Silver (BTCS). Load your wallet with a private key, send and receive BTCS.

Features

• Load Wallet: Import your wallet using WIF private key
• Send BTCS: Send transactions to any BTCS address
• Receive BTCS: Display your address and QR code for receiving
• Session Storage: Private key stored only in browser session (cleared when tab closes)
• Encrypted Storage: Optional encrypted wallet storage with password

Security Warning

⚠️ Web wallets are less secure than desktop/mobile wallets. Only use this for small amounts.

• Private keys are stored in browser session storage (cleared when you close the tab)
• Optional encrypted local storage uses XOR encryption (not production-grade)
• Always verify the URL before entering your private key
• For larger amounts, use the desktop/mobile Bitcoin Silver wallet

Building for GitHub Pages

Prerequisites

• Flutter SDK installed and configured
• Git installed

Build Steps

1. Build the web app:

   flutter build web --release --base-href "/web-wallet/"

   Note: Change /web-wallet/ to match your GitHub repository name.

2. Prepare for GitHub Pages:

   # The build output is in build/web/
   # This folder will be deployed to GitHub Pages

Deploying to GitHub Pages

Option 1: Deploy from build/web folder

1. Create a new GitHub repository (e.g., web-wallet)

2. Initialize git in the build folder:

   cd build/web
   git init
   git add .
   git commit -m "Initial deployment"
   git branch -M gh-pages
   git remote add origin https://github.com/YOUR_USERNAME/web-wallet.git
   git push -u origin gh-pages

3. Enable GitHub Pages:

   • Go to repository Settings → Pages
   • Source: Deploy from branch
   • Branch: gh-pages / root
   • Save

4. Your wallet will be available at: https://YOUR_USERNAME.github.io/web-wallet/

Option 2: Deploy from main branch (docs folder)

1. Copy build output to docs:

   mkdir -p docs
   cp -r build/web/* docs/

2. Push to GitHub:

   git add docs
   git commit -m "Deploy to GitHub Pages"
   git push

3. Enable GitHub Pages:

   • Go to repository Settings → Pages
   • Source: Deploy from branch
   • Branch: main / docs
   • Save

Updating the Web Wallet

1. Make your changes
2. Rebuild: flutter build web --release --base-href "/web-wallet/"
3. Copy or push the new build/web content to GitHub Pages

Development

Run locally:

flutter run -d edge

RPC Configuration

The wallet connects to a public Bitcoin Silver RPC node by default. The RPC credentials are encoded in the application for security through obscurity.

If you need to use a different RPC server, you can modify the encoded values in lib/main.dart or add a settings UI to allow users to configure custom RPC endpoints.
