This repository demonstrates how to perform an atomic-like Hedera Token Service (HTS) batch transaction using the Hedera JavaScript SDK. The demo covers:

1. Creating three test accounts with automatic token association.
2. Creating an NFT (Luxury Watch) and a fungible token (shares).
3. Batch-minting the NFT, distributing FT shares, pausing FT transfers, and submitting a topic message atomically.

• Node.js v14+ and npm
• A Hedera Testnet account (operator) with:
  • Account ID and private key

git clone https://github.com/hedera-dev/hip-551-batch-transaction-demo.git
cd hip-551-batch-transaction-demo
npm install

Create a .env file in the project root with the following variables:

OPERATOR_ADDRESS=<Your operator account ID>
OPERATOR_KEY=<Your operator private key>

node mintFractionalAsset.js

The script will:

1. Create three new test accounts with automatic token association.
2. Create an NFT, a fungible token, and a consensus topic.
3. Perform a batch transaction that:
   • Mints the NFT.
   • Distributes shares.
   • Pauses transfers.
   • Submits an allocation log via a topic message.
4. Print transaction statuses and the new account IDs to the console.

• mintFractionalAsset.js: Main demo script.
• accountUtil.js: Utility for creating test accounts.
• package.json: Project metadata and dependencies.
• .env: Environment variables (should not be committed).
