MetaMask Test Dapp Multichain for Tron

A test dapp for the MetaMask Multichain API on Tron.

Prerequisites

• Node.js (version 18 or higher)
• Yarn package manager

Environment Setup

1. Clone and Install Dependencies

git clone <repository-url>
cd test-dapp-tron
yarn install

2. Configure Environment Variables (Optional)

For basic testing, you can use the public TronGrid API (rate limited). For production use or higher rate limits, get an API key from TronGrid.

Copy the example environment file:

cp .env.example .env

If you have a TRON PRO API key, edit the .env file:

# TRON PRO API Key (optional)
# Get your API key from: https://www.trongrid.io/
VITE_TRON_PRO_API_KEY=your-tron-pro-api-key-here

# Default recipient address for testing (optional)
# If not provided, uses a default test address
VITE_DEFAULT_RECIPIENT=your-custom-test-address

Note: If no API key is provided, the application will use the public API which has rate limits but works for basic testing.

3. Development

Start the development server:

yarn dev

The application will be available at http://localhost:8081.

4. Build for Production

yarn build

Usage

Once the development server is running, you can:

1. Connect your Tron wallet (TronLink, MetaMask, etc.)
2. Test message signing functionality
3. Test TRX transfers
4. Test USDT TRC-20 transfers

Configuration

The application supports multiple Tron networks:

• Mainnet: Production network
• Shasta: Testnet for development
• Nile: Alternative testnet

Network configuration and contract addresses are managed in src/config.ts.
