Counterstake Bridge Frontend

A modern React.js Web3 frontend for the Counterstake Bridge, enabling cross-chain transfers between Ethereum, BSC, and 3DPass networks using MetaMask integration.

Features

• 🔗 Cross-Chain Transfers: Transfer tokens between ETH, BSC, and 3DPass networks
• 🔐 MetaMask Integration: Seamless wallet connection and network switching
• 🎨 Modern UI: Beautiful, responsive design inspired by 3DPass wallet
• ⚡ Real-time Updates: Live balance updates and transaction status
• 🛡️ Security: Trustless counterstake mechanism with automated assistants
• 📱 Mobile Responsive: Works perfectly on desktop and mobile devices

Supported Networks

• Ethereum (Mainnet & Goerli Testnet)
• 3DPass (Mainnet & Testnet)

Supported Tokens

Ethereum

• ETH (Native)
• USDT

3DPass

• P3D (Native, ERC20 Precompile at 0x0802)
• wUSDT (Wrapped USDT, ERC20 Precompile at 0xde)

Note: In 3DPass, all tokens (including the native P3D) are accessed through ERC20 precompile addresses, not through native token mechanisms like other networks.

Prerequisites

• Node.js 16+ and pnpm
• MetaMask browser extension
• Access to supported networks in MetaMask

Installation

1. Clone the repository

   git clone <repository-url>
   cd bridge-frontend

2. Install dependencies

   pnpm install

3. Configure networks (Optional) Edit src/config/networks.js to update RPC URLs and contract addresses for your deployment.

4. Start the development server

   pnpm dev
   # or
   pnpm start

5. Open your browser Navigate to http://localhost:3000

Configuration

Network Configuration

Update the network configuration in src/config/networks.js:

export const NETWORKS = {
  ETHEREUM: {
    id: 1,
    name: 'Ethereum',
    rpcUrl: 'https://mainnet.infura.io/v3/YOUR_INFURA_KEY',
    contracts: {
      counterstakeFactory: '0x...',
      assistantFactory: '0x...',
      oracle: '0x...',
    },
    // ... other config
  },
  // ... other networks
};

Environment Variables

Create a .env file in the root directory:

REACT_APP_INFURA_KEY=your_infura_key_here
REACT_APP_ALCHEMY_KEY=your_alchemy_key_here
REACT_APP_3DPASS_RPC_URL=https://rpc-http.3dpass.org

Usage

Connecting Wallet

1. Click "Connect Wallet" in the header
2. Approve the MetaMask connection request
3. Ensure you're on a supported network

Making a Transfer

1. Select Source Network: Choose the network you're transferring from
2. Select Source Token: Choose the token to transfer
3. Select Destination Network: Choose the target network
4. Select Destination Token: Choose the token to receive
5. Enter Amount: Specify the transfer amount
6. Enter Destination Address: Provide the recipient address
7. Review Stake: Check the required stake amount
8. Initiate Transfer: Click "Initiate Transfer" and confirm in MetaMask

Understanding Stakes

The counterstake bridge requires a security deposit (stake) for each transfer:

• Stake Ratio: Typically 10-20% of transfer amount
• Purpose: Ensures honest behavior through economic incentives
• Return: Stakes are returned after successful transfer completion
• Risk: Stakes can be lost if fraudulent transfers are attempted

Architecture

Components

• Header: Wallet connection, network switching, navigation
• BridgeForm: Main transfer interface with validation
• Web3Context: Global Web3 state management
• App: Main application layout and routing

3DPass Integration

The frontend includes special handling for 3DPass's unique ERC20 precompile system:

• Precompile Detection: Automatically detects and handles 3DPass precompile addresses
• Unified Interface: All tokens (including P3D) are treated as ERC20 tokens
• Asset Mapping: Maps precompile addresses to substrate asset IDs
• Validation: Special validation for 3DPass precompile transactions
• Contract Integration: Uses modified Export3DPass and Import3DPass contracts
• Automatic Approval: Handles ERC20 approvals for precompile tokens
• Stake Calculation: Real-time stake calculation from contract settings

Key Features

• MetaMask Integration: Automatic wallet detection and connection
• Network Switching: Seamless switching between supported networks
• Balance Loading: Real-time token balance updates
• Form Validation: Comprehensive input validation
• Error Handling: User-friendly error messages
• Responsive Design: Mobile-first responsive layout

Available Scripts

• pnpm dev or pnpm start: Start development server
• pnpm build: Build for production
• pnpm test: Run tests
• pnpm eject: Eject from Create React App
• pnpm lint: Run ESLint
• pnpm lint:fix: Fix ESLint issues automatically

Styling

The app uses Tailwind CSS with custom components.

Security Considerations

• MetaMask Only: Only MetaMask is supported for security
• Network Validation: All networks are validated before use
• Address Validation: All addresses are validated using ethers.js
• Smart Contracts: The contracts are open source and available for review (evm v1.1, evm v1-substrate)

Debug Mode

Enable debug logging by setting:

localStorage.setItem('debug', 'true');
