This Node.js script demonstrates how to interact with the dHEDGE decentralized finance platform using the @dhedge/v2-sdk. It involves creating an investment pool, adding liquidity, and performing a trade on SushiSwap within the Arbitrum network.

• Node.js installed on your system (Node.js 14.x or higher recommended).
• An account with a blockchain provider like Infura that supports Arbitrum.
• A basic understanding of Node.js and asynchronous programming in JavaScript.

1. Clone the Repository or Download the Script:

   If available, clone the repository using Git:

   git clone <repository-url>
   cd <repository-directory>

   Or download the script directly into your project directory.

2. Install Dependencies:

   Run the following command to install necessary Node.js packages:

   npm install @dhedge/v2-sdk ethers

3. Update the Script to Use Environment Variables:

   Ensure your script dhedge.ts retrieves the environment variables:

   require('dotenv').config(); // at the top of your file
   
   const privateKey = process.env.PRIVATE_KEY;
   const providerUrl = process.env.PROVIDER_URL;

   Install the dotenv package to load the environment variables:

   npm install dotenv

4. Compile TypeScript to JavaScript:

   Compile the TypeScript file to JavaScript if necessary, using the TypeScript compiler:

   npx tsc dhedge.ts

1. Execute the Script:

   Run the compiled JavaScript file or the TypeScript file directly (if using ts-node):

   node dhedge.ts

2. Monitor Output:

   Watch the console for logs indicating the execution of transactions such as pool creation, liquidity addition, and trading operations.

• Security: Keep your private keys secure and never expose them in publicly accessible areas. The use of .env for sensitive information helps avoid hard-coding credentials in your source files.
• Gas Limits: The script sets high gas limits to ensure transactions do not fail. Monitor and adjust these values based on actual transaction requirements.
• Error Handling: Enhanced error handling is implemented to manage and log exceptions effectively.
